Operations - The Crew Knows

As a follow-up to Bart's recollections and the very interesting and useful information that most of the time the crew knows where the cars belong, here's some more information from Dale along the same line. Actually, some very interesting information for more modern modelers. All photos by Dale Kritzky.

Even on the prototype, couplers may not match up. As long as it works...

Car Routing

One day when they got to Hartford, in the cut of cars was a CN box car. Dale initially said it wasn't theirs. They don't get CN box cars. The engineer checked the paperwork and said it was theirs. OK, Dale said, then it's not for (Home) Depot. They don't get CN box cars.

But his engineer said it must be, so they took it up and delivered it to Home Depot. A couple of days later, Home Depot told them it wasn't their car. As it turned out, it was for Hartford Lumber, an industry right at the junction, and one they have rarely had to spot a car.

When Dale had told me this, it confirmed that (most of ) the crew can often tell where a car is destined by the road/type of car. But there was something even more intriguing to me.

The Rules and Reality May Differ

But wait. Why was the engineer telling the conductor where the cars go? Or more specifically, why was the engineer handling the paperwork?

It's a great example of how the crew will find what works best rather than just following the standards or the rules. Since the CNZR is usually a two-person crew, the engineer had told the office that it was stupid that Dale (the conductor) had to manage the paperwork, and record the time when each car was spotted or picked up, etc.

While Dale is the conductor, he's also the brakeman, fireman, and everything except the engineer. As a result, it's much more efficient for the engineer to be recording the necessary information on the paperwork while he's sitting there waiting for Dale to throw the iron, or set/release handbrakes, etc. So that's how they do it.

In my era, the conductor wouldn't be busy on the ground, since there would be a head-end brakeman and a rear brakeman to be on the ground. There's more leeway on a shortline railroad where everybody does a bit of everything. I've heard many similar stories from railroaders on larger roads as well.

The saga of the CN box car continues. After they were informed it wasn't for Home Depot, they had to take it back down to Hartford Lumber. As I mentioned, they rarely had to spot a car there. In the meantime, a shipping container had been shoved back against a chain link fence, which was pushed too close to the rail. So the car peeled away several yards of fence, which then needed to be cut out so they could spot the car.






Misrouted Cars

There was a day when I had stopped by and there was another car that was a bit of a problem. The day was busy, and there were more cars than fit on the runaround in Hartford. This presented its own problem, and I'll explain how the resolved it in a moment.

The reason there was too many cars is because Pan Am had made a mistake a couple of days before. The CNZR crew had left a car for CSOR, but Pan Am had picked it up. So on this morning, Pan Am, after realizing their mistake, had brought it back.

So because of this extra car, they had to determine how to deal with the fact that they essentially had no runaround. One option was to shove a car or two up the Hartford Lumber track. That would provide enough space for a runaround. But it also added a number of extra moves.

Instead, they decided to operated in a push-pull configuration. First I should point out that they planned out these moves before they even got on the locomotive for the day. When they went to pull the cars from Home Depot, they left one locomotive on the main, pulled the cars, and then had a locomotive on either end of the train.

This meant that when they got to Hartford, they could run the locomotive with the cut of outbound cars down one side of the runaround and hold. Then they uncoupled the rear locomotive and used that to pull the cut of cars that fouled the other end of the runaround. That allowed the lead locomotive to escape from the other end of the runaround, after they added the extra car to the cut of outbound cars.

Bad Order Cars

On another day, there was a box car that had a broken bell crank, which meant that you can't set the handbrake. Dale told called his office and CSOR and told them that he wouldn't accept the car until it was repaired. They wanted him to accept it and have it unloaded first, but he still refused and they had to fix it first.

After the repair.

Here's the applicable rules from the 1943 New Haven Rule Book, under the section for Freight Conductors:

826. They must not handle a car which is found to be overloaded or improperly loaded or not in condition to run safely and report cars in such condition to the superintendent promptly.

827. They must, when bad order cars are set out of the train, report the fact to the superintendent promptly, advising nature of defect, where waybill or manifest was left and note on waybill or manifest the point at which car was left. 

This could be done on the model as well. I've seen some ops sessions that use cards to identify bad order cars for whatever reason. But on the prototype a cut of cars is walked to check for defects, set/release handbrakes, test the brakes, etc. On the model, the conductor should also be checking the train. If defects are found, issues with the coupler, damage to the handbrake, or things like broken sill steps, could be flagged as a bad order car and either refused or set out to be repaired. This would be useful for the layout owner, because they'll know which cars have broken parts

Empowering Your Crews

I enjoy this sort of operation since it provides some interest and work aside from just dropping off and picking up cars. It's more immersive, and also better models how the prototype actually operates. More importantly, it makes your crews a more integral part of the operations, and empowers them to make decisions and do the job like the real crews. Yes, there are rules to follow, and often a dispatcher or yardmaster who must provide permission to do the work. But once permission is granted, it's the crews that determine how to actually do their work.

Operations - Local Freights and Freight Houses

I've been meaning to put this post together for a while after asking more questions of Bart Hollis, former head end brakeman on the Highland Line at the end of the New Haven (he hired out in 1968 in East Hartford Yard, then moved to the Highland after 6 months, so really at the end...)

He worked NX-17 (Waterbury to Plainville) and has been able to confirm much of the research Chris and I have done. There were some surprises as well, but they make sense. 

The Work of the Local Freight

Bart says the conductor received, "a list of the cars in the train with instructions as to where they were to be spotted." 

He also says he doesn't quite remember, but thinks they were given the waybills too, but then indicates the waybills would be delivered to the agents in Bristol and Plainville, so they must have had them.

This would be a the Consist/Wheel Report that we've seen in earlier posts. From Hartford, Maybrook, Cedar Hill and others these would be printed via Teletype. From Waterbury it would still be a handwritten report. This lists all the cars in the train in order, from engine to caboose, and their destinations. In other words, for a local freight it tells you everything you need to know about the cars in your train.

As we know from other research, the waybills would travel with the conductor, and this confirms that they would be given to an Agent once delivered. That is, they don't go to the industry (since they are railroad documents).

I expect that if the Yardmaster knows of any cars to be picked up they would also tell the conductor at that point. 

Bart then provides a town-by-town description of the work:

"The first siding was at Terryville. There was a passing siding on the south side of the track which was only used if we had to double the hill. There was also a trailing point switch that went to the north side that went into the woods and ended. I was told it went to a clock factory years ago. There was a trailing point switch that had a short track that ended on a trestle and only once did we spot a loaded car of coal there."

DERS-1 (DL-109) 0733 entering the east portal of Terryville Tunnel. Tom McNamara
You can see Terryville station and the passing siding in the distance.

"The next switch was the passing siding at Bristol. Off the siding was the house track. When I first started we would occasionally get a car for the house. There was also a track that went just beyond the station that was used as a team track. There was an agent at Bristol by the name of Coffee (I forget his first name). If we had a car for Bristol, he would tell us exactly where it went and if there was one to pick up he would tell us the road and number. I don't know if the conductor got any paperwork, though."

Bristol 1948

There are a couple of interesting things here. First is that they received an occasional car to spot on the house track. More on that in a moment.

The second bit of info, of course, is that the Agent in Bristol told them what work they had. In a small town, this very well may have been a verbal exchange, although for a pickup the waybill would still be given to the conductor. 

"The next break in the rail was Bristol Brass. It was a facing point switch, so we had to work that place on the return. The Bristol agent was responsible for it and so the same instructions came from him."

They received their work while in town, but would work it on the way back.

"The next break was at Hildreth Press. A printing company. This was a trailing point switch that had another track off it. Again, it was handled by Bristol. This place had four spots. They would get a load of paper cars and we had to store them on the passing siding at the Bristol station. I remember as many as twenty loaded cars consigned to Hildreth Press."

By this era, with no passenger trains scheduled on the Highland Line, there were no passing sidings remaining. That is, the track was there, but they weren't designated in the Employee Time Table as a Siding. The Rule Book only defines two types of track:

  • Main Track: A track extending through yards and between stations, upon which trains are operated by time-table or train order, or both, or the use of which is governed by block signals.
  • Siding: A track auxiliary to the main track for meeting or passing trains.
There are three other related definitions:
  • Single Track: A main track upon which trains are operated in both directions.
  • Two or More Tracks: Two or more main tracks, upon any of which the current of traffic may be in either specified direction.
  • Yard: A system of tracks within defined limits provided for making up of trains, storing of cars, and other purposes, over which movements not authorized by time-table, or by train order, may be made, subject to prescribed signals and rules, or special instructions.

In other words, the Main Track(s) refer only to tracks that are controlled by time table, train order, signals, or later forms of control.

A Siding was a track that was specifically identified in the Employee Time Table for the purpose of meeting or passing trains.

Yards only exist between Yard Limit Signs (a type of fixed signal) and do not require train orders for movements on those tracks. We know that additional rules govern the use of the Main Track within Yard Limits.

So what are the other tracks? They aren't listed in the definitions, but they are referred to in other rules ("Sidings and other tracks to the right of the main track" for example). In the Engine Restrictions section of the ETT we can see a number of examples, such as house track, bulk track, brick yard tracks, industrial tracks, run  around track, plus many identified by name, such as A.H. Hayes Fuel Co. track. They are also frequently referred to by track number.

 (Model) railroaders often call them sidings or spurs. When working with real railroaders, they tend to refer to them by name (Depot box car track, Depot flat car track, etc.) so there's no question which track they are referring to.

Anyway at this point the former Sidings in Terryville, Bristol, and Forestville are now used by the crew as needed, which is exactly what Bart describes. In my era, these were still in use as Sidings, and they would have had to inform the Dispatcher if they were to leave a cut of cars on any of them.

"Next was Wallace Barnes. Again, a trailing point switch. They received covered gondolas loaded with steel coils. Once more, handled by Bristol.

Two RDCs at Forestville in September 1956 (McNamara).

Eagle-eyed readers who know Forestville might notice something odd about this picture...

"Then came Plainville." 

Three trains at Plainville, 1948 (Cochrane).
I-1 1001 with a passenger train at Plainville station on the eastbound main.
DEY-5 (S-2) 0604 with YN-3 coming down the east leg of the wye onto Track No. 5.
Between them, you can just see the caboose of the Bristol local on the westbound main.
That's known as HDX-3 in 1948, but NX-17 in 1968.

There was an operator and an agent there. The agent's name was Ed Coffee, brother to the Bristol agent. Almost all of the loads bound for Plainville came via NX-25 out of Hartford. Occasionally we would be asked to spot one or more of them and once in a while we would pull a load back to Waterbury. I remember a few times we would take a car from Plainville north on the Canal Line to a lumber yard and/or a cement place. Not often. Then, a few times we took a car south on the Canal Line to either a lumber yard or a car of casting sand to a forge. I believe these place were within Plainville Yard Limits as I don't remember ever getting orders to go there."

I love the fact that the two agents on the line were brothers. But this also confirms that the Agent would assign work as needed to the crews that were available where there were multiple trains.

What about the lack of paperwork? I asked whether the orders were verbal or written, and his reply was very informative (and hinted in the notes above):

"For the most part, we could tell by the type of car and the road which one went where."

He also clarified, "As I remember, the only time we got a list was a hand written note with the road and number for Hildreth Press. The rest of the cars were obvious."

Another question I had is whether an industry would tell them to pull a car, or if they had to get permission from the Agent.

 "If the consignee asked us to pull a car, we would as a service to the customer."

This makes sense, although they would still need to get a waybill from the Agent before the car could move on the railroad. Because the Agents along the line would know the work (or the crew calls ahead), I suspect this would be relatively rare. But if they were pulling a car from an industry that is prior to reaching the station, then they would get the waybills from the Agent at that point. 

So while the New Haven had forms for switching at yards, and must have had something for the road too, the reality is that these sort of working documents (that didn't have to be saved for recordkeeping purposes) weren't needed as much for regular crews. They knew their industries, and how they would work them. In the era Chris and I are modeling, there are more industries, and they would be receiving more house cars. So the paperwork would still be important, although the crews will still be able to pick out the obvious cars. They would also use chalk marks to identify specific cars.

Operating a Local Freight 

From a model railroad operating viewpoint, while you may want to know what your work will be ahead of time, most of us won't know a model railroad as well as a crew that works it 5 days a week. After a quick glance to see if there's something unusual, I think the key is to approach it one town at a time.

The train should be blocked by town, as on the prototype. Prior to leaving one station (town), the conductor should already be looking at what work will be done at the next town. Identify the end of the cut, then start by identifying which industries will be served, and an efficient order on how to serve them. 

You don't have to worry about the specific cars at this point, just the industries and the order to serve them. It doesn't matter which order the cars are in the block at this point, because you'll simply cut the train just behind the car that is being dropped at a given industry.

The train may pass some industries on the way into a town. If there are cars to drop, then the train can stop on the way. To determine if there are cars to pick up, then can get that info from the prior station, or the industry can give it to them there. In either case, they can pull the cars, and pick up the waybills from the Agent prior to leaving town.

It's also not uncommon for a Siding or track to be near the center of a town. That is, the local freight would come to the station, pull into the siding to clear the Main, then go get their work from the Agent. They would leave their train on the siding and go back to work any industries in that town that they already passed. It wouldn't be uncommon to work both sides of town before putting their train back together and continuing to the next one.

For a layout owner, I would recommend providing some information for pickups at the start of a run, and the rest would be communicated along the way. When the train arrives in town, the conductor should have already planned out how they will work the industries, and usually they will get their additional work from the Agent (it could simply be a box with a card).

Don't be afraid to spend a few minutes finalizing your planned moves in that town. Again, I think the focus should be on how you'll work the industry itself, don't pay attention to specifically which cars. Then when you go to switch each industry you can look at the cars in the train and determine where to make your cut. 

Freight House Traffic

Chris and I had been told that some freight houses (such as Rocky Hill) were served by truck in our era. Combined with sources like the ETT which lists what stations are open for Train Orders, came to the conclusion that there wasn't an Agent at many of those towns. This is related not only to traffic at the freight house, but also how the crew receives work.

The funny thing is, I believe I've had the answer for several years now, and just didn't realize it. As I've been digging through paperwork, I missed a subtle but important point. The Freight Car and Package Car schedules list scheduled L.C.L cars to the freight houses. I originally thought any remaining traffic to the freight house essentially used it as a bulk/team track. I now think that's incorrect.

I think the freight house could still receive cars, or be used to load cars, they just weren't scheduled. These freight houses were on scheduled truck service from freight houses that received scheduled service, but traffic that wasn't part of those scheduled cars would have still gone direct to the freight house in that town.

Of course, even if the freight house only received from trucks (which I now know is incorrect), they would still have a Freight Agent, and that agent would still be the point of contact for local industries and the place where crews would receive their work. For example, by the 1966 ETT Bristol was not open for Day Train Orders (only Plainville). On the Valley it was Wethersfield and Middletown.

But industry work isn't a  Train Order. That is, they aren't orders that give them permission to occupy the Main Track. Train Orders aren't required to occupy an industry track. So whether or not a station is a Day Train Order station doesn't tell us whether there is a Freight Agent on duty, and Bart's recollections prove that.

So how can we tell?

Well, indirectly any freight house that has scheduled service by rail or truck must have a Freight Agent. That Agent would provide the local work for the crew. But there's also a publication that specifically identifies every station with an Agent.

Official List of Open and Prepay Stations

Open and Prepay Stations for 1949

Issued annually, this book lists every freight station in the North American Rail System, including Canada, Mexico and even Alaska (although from what I understand it wasn't directly connected to the rest of the rail system). Hawaii is not listed, although Cuba (!) is.

Like all such books, entries may have numerous notes.

The first note (designated by an asterisk) states: No Agent. Freight charges to this station must be prepaid. Except as otherwise provided, to order (or negotiable) bills of lading must not be issued to a station where there is no freight agent. In other words, every active freight house is listed, and it identified which ones have an Agent and which do not.

So for Chris' benefit (and to satisfy my curiosity), here's the Valley Line in 1949:

Essex, Deep River, Chester, East Haddam and Moodus, Higganum, Cromwell, Rocky Hill, and Wethersfield are all Open. South Wethersfield is Prepay (no Agent) and there are several notes that apply:

1. Carload freight only. (South Wethersfield)

76. A very long note: Shipments for the following points, except "Shippers' Order Notify," when consigned to the persons or firms named, may be forwarded "Collect," unless shipments are of such nature that the governing "Classification" requires prepayment: Shipments for all other consignees must be prepaid. There are then several pages of Stations and Consignees to which this applies. For South Wethersfield it only applies to B. O. Pelton. (South Wethersfield)

126. Nearest less than carload delivery for this station shown is: Chester > Deep River; South Wethersfield > Wethersfield. This rule likely always accompanies Rule 1 to inform shippers where to route L.C.L for that station. (Chester and South Wethersfield) 

1560. Carloads only, except that less than carload shipments in lots of 4,000 pounds or more will be handled from or to industries having private sidings. (Chester)

So my earlier interpretation was wrong. The freight houses in our era are still active, if low volume.

Operations - Paperwork for Stanley Works

 As I've been working on operations, one question has been what sort of paperwork, if any, would I be using for Stanley Works? They won't have waybills, since those are created by the railroad and must go to the Freight Agent when delivered.

Since I have switching lists for the New Haven, I figured I'd use something similar for Stanley. I recently found something on eBay that shows I'm on the right track.


This is a booklet of Conductor Car Reports from an industry -  The New Jersey Zinc Co (of PA).
The booklet also had a time card:


In the lower right of the time card it notes S&M Department Railroad Division. Presumably, based on the paperwork, this company has their own locomotives.

The New Jersey Zinc Co (of PA)



As this Sanborn map shows, the NJ Zinc Co was located along the Chestnut Ridge and Lehigh & New England Railroads. The CNJ (presumably the CRP in most of my era) looks like it may have served a plant at the other side of town. The Lehigh Valley was also across the river from this plant.

Here's a picture of part of the west plant:


The town of Palmerton was a company town, built by the NJ Zinc Co (of PA) and named after it's president at the time (who apparently didn't like that).

The company was apparently the largest producer of zinc in my era, which is useful since Stanley Works has a galvanizing building at their main plant in New Britain. I can believe that, here's an aerial view of the west plant from 1931, looking east:


From what I understand, they had from 2 to 4 Alco S-2 switchers, which replaced earlier steam switchers. I believe they acquired them at the same time the Chestnut Ridge Railway received theirs. 

It's clear that the west plant has a yard at the west end of this plant. The LNE has a direct connection to the east plant. In addition, the Chestnut Ridge Railway has connections to both.

Chestnut Ridge Railway

This was a small short line that, according to a newspaper article, hauled 4 million tons of freight in 1947 and 1948. Their primary (only?) customer by that time was the NJ Zinc Co (of PA). It clearly connects to the LNE at the east plant in Palmerton. Another article notes that it was originally built with a connection to the CNJ for passenger, mail, and the primary freight commodity of bricks before the Zinc plant was built. Passenger service, as on so many branch lines, ended in the '30s.

Zinc and zinc products for New Britain can come via CRP/CNJ then by carfloat to the NH and to New Britain via Cedar Hill. A more direct routing would be LNE to Maybrook to New Britain.

In the aerial photo above, you can see the LV (lower tracks) and LNE (upper tracks) on the other side of the Lehigh River. 

The Chestnut Ridge Railway crosses over the CNJ/CRP (on a bridge) in the upper left. Although not on the Sanborn map, I believe the tracks that come down the berm to the yard to the left of the CNJ Main is also the Chestnut Ridge Railway. The CNJ station is tucked up against the curve in that berm.

Right along the top edge of the photo you can see the LNE branch that's heading to the east plant. 

Operational Paperwork

It certainly looks like an interesting place to model, but what is of most interest to me is the paperwork.

The pages are perforated, several are missing, and it was clearly used because I may be able to figure out some info from the prior form since they had written with a heavy hand.

It would make sense that a company large enough to have their own locomotives would have their own railroad department. They would not only have to have an engineer, but also a yard foreman (conductor) and most likely a brakeman. In addition, they would needed a shop and crew to maintain their locomotive(s).  I don't know think they would fall under railroad union rules, but they would probably have operated much like any small railroad. 


The Conductor's paperwork is simpler than the railroad's. All of the traffic to/from Stanley Works interchanges with the New Haven. The Agent will also serve as the Stanley Yardmaster. I'll create a similar Yard Check paper for Stanley Works. I'll also need some method to release those cars through the session, as they won't all be ready to pull at the start of the session.

These forms can be used as they are designed, and issued to the Stanley switching crew as needed, just as the New Haven switch lists are given to the crews throughout the session.

The Senator takes a Vacation

Well, part of it anyway.

Dale informed me that this move was going to happen on Sunday, but unfortunately I had to work. So he made sure to take some pictures.

For years (decades?) there have been two ex-Senator PRR parlor cars on one of the tracks at the Hartford Regional Market. The Greenwich Estate was previously named Betsy Ross and Greenwich Harbor was Roger Williams.

They are owned by Dale's boss' (owner/operator of CNZR) brother. I guess for a while Amtrak wasn't allowing the use of private cars. But apparently that has changed, because the cars' owner and his wife are going on vacation to Florida - in their ex-PRR Parlor Cars.

CSOR coupling up to the cars.


Heading out.




Dale has been working this summer just hanging out in his truck all day 
to protect the one train that comes through, and move the construction crew.
This is an industry track off of the old Valley Line, which is on the other side of the overpass.



At the Springfield Line in Windsor Locks, waiting for a southbound Amtrak shuttle...



...and a northbound CT Rail to pass...



With the special following close behind.




The cars are on their way to Springfield and will be added to an Amtrak train to Florida there. What a way to travel! I wonder what sort of service they'll have onboard.

Milwaukee Rib Side Cars

On Friday I posted a list of plastic freight cars and mentioned that the Exactrail Rib Side car is the better option for the early Milwaukee Rib Side Box Car, but that it was hard to find. Today I received a notice that it a new run is coming soon.

So let's take a closer look at this prototype and this model.

Milwaukee "Rib Side" Welded Box Cars

The Milwaukee Road built their unique welded "Rib Side" cars between 1937 and 1947. These were welded cars, using long panels arranged horizontally. The ribs were more than just a corrugation, and not hat-section (u-section) ribs attached to the side as many have thought in the past. Each sheet of steel was bent upwards enough for the next lower sheet to nest into the bend, and then the main portion of the rib corrugation provided stiffness. These panels were welded together along the bottom seam. Part of the reason for this type of construction was that the cars were built using Inland Hi-Steel. This steel was more corrosion resistant than the standard steel used in car construction, and was also lighter - an advertisement claimed as little as half the weight.

Other cars built with such lightweight construction had additional stiffeners, and corresponding rivets, between the main supports as seen in the so-called "Alternate Center Rivet" (ACR) car designs. Another approach was more panels (12-panel cars), and many used welded construction like these cars.

The end result for the Milwaukee cars was a unique signature design that is easy to spot in photos, even at an oblique angle. Chris and I have seen many on the NH, such as this one on the Valley Line.

The first cars built with this type of construction were 500 50' Automobile Cars built in 1937.

From 1939 to 1940 they constructed 3,188 40' Box Cars. All except for one of these cars featured "long ribs" that continued behind the ladders, and the "Type 1" Murphy double panel welded roof. These had 11 double panels, plus short end panels. The later roof used on cars built from 1941 to early 1947 had one fewer panel and wider end panels.

  • 18000-21187 - 5/5 Dreadnaught End with lumber door, early Double Panel Roof (3,188)

Rib Side Cars grouped the short-rib cars into four phases.

  1. 21188-22187 - 5/5 Dreadnaught End with lumber door (1,000)
  2. 22188-23937  - 4/4 Improved Dreadnaught End with lumber door (1,750) (Intermountain)
  3. 23938-25537 - 4/4 Improved Dreadnaught End, no lumber door (1,600)
  4. 25538-28559 - 4/4 Improved Dreadnaught End, no lumber door, Diagonal Panel Roof (3,022)

Accurail acquired the Rib Side Cars tooling, and have released a couple versions so far. Note that they identify their cars differently. They label their long-rib car as "Phase I" which means the short-rib cars, should they release them, will be Phases 2-5.

The 40' Double-door Automobile car was built only in the short-rib variation. In addition to the rib sides, they are unusual in that there is a removable center post between the two doors, making it appear as if it is a two-door box car, rather than a double-door car.

  1. 6500-7099 - 5/5 Dreadnaught end with lumber door (600)
  2. 9000-9499 - 4/4 Improved Dreadnaught End with no lumber door (500)

There are basically two designed for 50' cars in both single- and double-door configurations. A small number of cars with shorter interior heights were built as express or merchandise cars, I haven't included those here. Only the first group had the long ribs (and were the first rib side cars built).

  1. 13500-13999 - Double-door, 5/5 Dreadnaught End with lumber door, Hutchins welded roof (500)
  2. 50000-50599 - Single-door, 5/5 Dreadnaught End with lumber door (975)
  3. 140000-14429 - Double-door, 4/4 Improved Dreadnaught End, no lumber door (500)
  4. 15500-15749 - Single-door, 4/4/ Improved Dreadnaught End, no lumber door (250)

In photos on the New Haven we've seen pictures of the 40' and 50' cars, and both the box and automobile cars.

Models

There are other models that have been produced, but don't reach my level of accuracy and/or fidelity so I won't be including those.

Sunshine

The Sunshine kits, of course, are very good. There are a couple on eBay now, but they will typically sell for ~$75+. I don't own either, and while I've seen finished models I haven't studied them carefully.

The first model is the 13500-series of long-rib automobile cars. This is the only model available in this configuration, and I may eventually pick one up for that reason.

The second variation they produced is the long-rib box car, or the same as the Exactrail car, and also the long-rib Rib Side Cars model, which has since been released by Accurail.

Exactrail

The long-rib 40' cars were the largest group of cars. There are minor issues. The lumber door is the biggest one, it should be slightly recessed and it's lacking the rivets around it. It looks like it's a separate part, though, perhaps it can be modified.

The retainer valve is hanging in mid-air, the pipe should bend above the top of the upper corrugation and be mounted to the end of the car. The bottom of the pipe is also hanging in mid-air, instead of bending to go under the car. The Intermountain one is similar. The brake appliances are lacking some piping that is on the Intermountain car, and is a slightly different configuration. I don't have a diagram handy to verify which is correct.

In Railway Prototype Cyclopedia 13 it lists 164 car numbers confirmed to wear the "Route of the Electrified Olympian" slogan. All of them are long-rib cars. Six of the Exactrail cars will be released in this scheme (4 built in 1939, 2 in 1940. Of those 164 car number, 91 were built in 1940. 

Intermountain

This is also very accurate and also must-have in my opinion since the shorter ribs are noticeably different than the earlier arrangement. The detail is perhaps slightly less fine than the Exactrail car, for example the intermediate corrugations on the Improved Dreadnaught End are a little narrow. And the handled the retainer valve in a manner similar to the Exactrail car as well. But overall it's very well done.

Accurail/Rib Side Cars

These models were originally produced by a company that only made Milwaukee Rib Side prototypes, and most of the variations are therefore available in plastic. Accurail has released two of the versions so far, and I don't think any modifications were made to the tooling.

The tooling design varies depending on the car. All are well done, although the roofs aren't quite as good as the Exactrail/Intermountain cars, and the details aren't as fine. The running boards are well detailed injection-molded plastic, but aren't see-through (Most of the Exactrail wooden running board is also not see-through, just in a couple of locations such as part of the lateral running boards).

The long-rib 40' car is the same as the Exactrail and Sunshine car. The few grab irons on the car are molded on. This is one variation to be re-released by Accurail, but the Exactrail car is better and RTR.

The short-rib car was produced in all four phases. They have an innovative approach to the bracket grabs on the left end of the sides, with the brackets molded on, and holes pre-drilled for wire grabs. Although the Intermountain tooling is a bit finer and has more details, there is one specific detail that the Rib Side Car models have that the Intermountain is lacking. There is a vertical line that should delineate the end of the ribbed portion of the car side where it is welded to the flat "pans" next to the door. Intermountain did get this vertical seam at the ends, but not by the doors for some reason.

The 40' Automobile Cars have molded grabs, and unlike all of their other models, the doors are cast into the car side. Brass models tended to attach the removable center post to one of the doors, so you could open one (but not the other since the post went with it).

The 50' cars, only the short-rib versions, are designed similarly to the 40'short-rib cars, except that the brackets for the grab irons at the left end don't stand free from the side, it's just the base and holes drilled for wire. The Improved Dreadnaught End main corrugations are a bit too "straight" and mostly lack the bulge in the center.

Comparisons

Here are some comparison pictures of the models I have.

Roofs of the Rib Side Cars, Intermountain, and Exactrail models.


The Rib Side Cars lumber door on the left is better detailed than the Exactrail.


The Intermountain lumber door is a different design and a pretty good match to the prototype.

The Improved Dreadnaught Ends of the Intermountain and Rib Side Cars models.
Neither are entirely accurate, but the Intermountain are better.


I already shaved off the molded on grab irons on the Automobile Car.
Ignore then in-process paint removal...


Both 50' cars have the same bracket grab base, with holes drilled for wire grab irons.


The 40' "Phase 1" Rib Side Car models (5/5 Dreadnaught Ends, short-ribs)
have actual brackets drilled for wire grab irons.


You can see how they extend from the car side.
This is an innovative and well done design.

As you can see I have several of the Rib Side Cars models, most in the wrong paint schemes, so I'm stripping them. They show up on eBay occasionally, but not that frequently and not always in the paint schemes I need. Hopefully Accurail will produce more of the variations that Rib Side Cars tooled. I have the 40' Automobile Car on the way, so that eliminates some of the work on that body.

Because these cars are so visible, I think having a couple makes sense since more than one may be on the layout during a given session.
