Rail Length

 


Getting ready to move a pile of rail from here to there at Depot St. I walked about 3 miles around the circumference of a 20’ radius circle in an afternoon.

What I also found interesting is the ratio we were moving. It was rolled in 1915 and 1922 for the NH, 107 lb rail taken out of the Canal Line near the Massachusetts border.

New Haven Rail

What’s the length of a piece of rail? The conventional knowledge is 39-feet, so it would fit in 40-foot gondolas. While that is true, 40-foot gondolas weren’t always the standard length pre-depression. In addition the surveying, real estate, and railroad industries use some standard systems of measurement.

These rails are two rods long, or 33-feet long, a rod being 16.5-feet. Of course, that worked well since it fit in 36-foot cars. The NH didn’t have 40’ gondolas (or flat cars) until the 58000-series of gondolas were built in 1929. (For more on those, including a diagram, see this post.) So they may have continued to receive 33-foot rail until those cars were built.

The 16.5-foot rod is related to other measurements - a chain is 4 rods (66-feet), a furlong is 10 chains (660 feet), and a statute mile is 80 chains. The surveyors’ chain is just that. A chain with 66 foot long links.

So for those modeling earlier eras (pre-depression to a large degree), it may be more appropriate to put those joint bars every 33 feet instead of 39 feet. This is appropriate on some lines even today, large portions of the CNZR is CNE/NH rail from pre-1926, the oldest I think from 1896-7. The Highland Line is still largely 107 lb NH rail, so I’ll have to go take a closer look at when it was produced. I suspect that I’ll need to go with that measurement on the layout.

Rail Code

Another question that comes up frequently on Facebook and other groups is, "what code rail should I use?"

Well, I probably couldn't get a better picture than this to show why you might want to consider different code rail on your layout:


The new rail is 131 lb., and the old rail is so worn I haven't been able to find any markings. It is the smallest rail that I think I've ever found. How can I figure out what size rail it is?

Measure it.


It's 4" tall. I happen to have several original NH documents regarding rail dimensions.


This page isn't dated but doesn't have any rail that's only 4" tall.



This one did, though. It's 56 lb. rail. There's another page that's a fold-out and too large for my scanner, but it confirms the dimensions. Even better, it lists all of the standard rail dimensions, and notes which ones the NH used:


Once again, we find that the 4" rail is 56 lb. Here are a couple of additional pages from the book regarding rail:




How does this apply to our modeling? 

Conventional modeling wisdom is to use Code 83 for main tracks, and Code 70 for sidings and yards, and occasionally with Code 55 for light industry tracks. The fact is, for many modelers it should be Code 70 and lighter.

To start, a quick refresher on rail codes. Model rail is measured by "code" which refers to the height of the rail. Code 100 is 0.10" and Code 70 is 0.70" tall. The prototype refers to the weight of the rail, per yard.

There are many sources that relate the two, a common one I see (such as this one) is:

  • Code 100 = 156 lb. rail
  • Code 83 = 132 lb. rail
  • Code 70 = 100 lb. rail

Or this one from the NMRA that indicates Code 100 "represents" 152 lb. rail instead of 156 lb. rail.

But the NMRA data shows it's a bit more complicated:

  • 155 lb. rail would actually be Code 92 (and 152 lb. rail would be maybe Code 90).
  • Code 83 falls between AREA 140 lb. rail (Code 84) and AREA 132 lb. rail (Code 82).

Railway Prototype Cyclopedia 5 has a chart detailing several brands of rail, in various scales, which fills in some holes. I use Microengineering track/rail, which is:

  • Code 100 = 177 lb. rail (!)
  • Code 83 = 136 lb. rail (Code 82 is 132 lb., Code 84 is 140 lb.)
  • Code 70 = 108 lb. rail
  • Code 55 = 74 lb. rail

Can we even model the 56 lb. rail? Microengineering makes Code 40 rail, although it's designed for N-scale. But it would be even smaller, about 3.5" tall or the equivalent of 40 lb. rail. On the NMRA RP 15.1 it shows 55 lb. rail is Code 47.

Based on the common designation of Code 100 = 155 lb, it's often noted that the only use of such heavy rail was the PRR on a relatively short section of their heaviest mainlines. This isn't quite true. As it turns out, 155 lb. rail is noted on a NH Rail Weight Diagram (updated through November 9, 1954) in a very short segment on the westbound main track just west of Saybrook. I believe it was also used on the P&LE in at least one segment. Regardless, it's not widely used.


The rest of the rail on the westbound main track from Boston to Woodlawn is 130 lb. or 132 lb. rail. Some sections of the eastbound main are 140 lb. rail, much of it welded.

If the Shoreline is 132 lb. rail, or a close match to Code 83 and the Maybrook Line is 130 lb. rail, it seems that the old standard of "Code 83 for the main tracks" holds true.

Or does it?

If you look at the diagram, the only other major section on the entire New Haven Railroad with 130/132 lb. rail through 1954 is Middleboro to Matfield, MA. The Springfield main track is 112 lb. rail (along with Groton to Norwich), with all of the rest of the rail on the New Haven 107 lb. or lighter. The Berkshire Line, Highland Line, Most of the Norwich & Worcester, parts of the Air Line, Midland Line, and the Canal Line north of Plainville are all this weight rail.

Branch lines, like the New Hartford, Griffins, Suffield, and even the Valley Line are under 80 lb. rail. An earlier map reveals these to be primarily 78, 79 and 80 lb. rail.

So unless you're modeling the Shoreline, Maybrook Line, or Springfield Line, your New Haven layout should be Code 70 or even Code 55 for the main tracks.

There are far more prototypical rail weights than available codes of model rail, because it's not practical to manufature all of them. Here's how I would cover the range of rail weights:

  • Code 83 = 122-140 lb. rail
  • Code 70 = 91-121 lb. rail
  • Code 55 = 74-91 lb. rail
  • Code 40 = anything less than 74 lb. rail
Another way to think of it is heavy, medium, light, and extra light rail. 

So yes, Code 83 for heavily trafficked main tracks. Otherwise, Code 70 for main tracks, and Code 55 for others. While this covers only the NH, I suspect it holds true for a lot of other railroads through the '50s (at least).

New Haven standard rail weights are: 56, 60, 67, 68, 70, 74, 75, 78, 79, 80, 90, 93, 100, 107, 130. That's 15 different rail profiles, although I think this was largely because the NH was consolidated out of many smaller roads and they each used different rail.

  • Code 83 = 7.1" tall, New Haven 131 lb. rail is 7-1/8" tall.
  • Code 70 = 6.1" tall, New Haven 107 lb. rail is 6-1.8" tall.
  • Code 55 = 4.8" tall, New Haven 78 and 79 lb. rail is 4-3/4" tall.
That's a pretty close match in my opinion.

Prototype Usage

Really? Code 70 for most model railroads? Yes, at least pre-1970, and probably much later too.

The NMRA has a chart at the bottom of RP-15 - Rail that compiles prototype usage of different weights of rail from 1940 to 1960. What I find very interesting is that in 1960 only 25.66% of rail in use on Class I railroads was 120 lbs or heavier.

That is, in 1960, only 25% of rail in use was the equivalent of Code 83.

The rest would be the equivalent of Code 70 (52%) or less; ~20% would be Code 55, and the remainder even lighter, or Code 40.

I don't have percentages for eras later than 1960, but as you can see the adoption of heavier rail was fairly slow. Part of that is because the heavier rail is primarily installed on heavily used main tracks. A lot of the time that old rail that doesn't meet the standards for heavy main track use can still be used on branch and lighter used lines. So the rail gets reused, and the oldest rail slowly gets replaced. 

Here's an old webpage on the Internet Archive that has information for a number of prototypes:

Today

What about more modern modelers? I don't have a lot of info, of course, except for what I've seen around here. Over on the ex-Highland Line and the Canal Line (in Plainville) it is still predominantly ex-NH 107 lb rail (Code 70). But it can vary.

The CNZR has slowly upgraded portions of the track over the years. They get rail from other roads in the state. From what I understand, since the state owns the railroad, when rail is taken out someplace else, such as the Springfield mainline, it has to be made available for the smaller railroads. A freight-only line with low speeds doesn't need the same weight of rail as a high-speed main track. In a few hundred feet I found rail in use from as early as 1908, and up to 140 lb. welded rail. Compromise joint bars must be used between sections of different size rail, and in some cases, there are very short sections of a given size simply because they need to use multiple size compromise bars to get from a very small weight rail to a much heavier size. In a lot of cases I could barely read the old markings, but the first one is the standard NH 107 lb. rail that is still common throughout CT.











This sort of detail may seem very particular, but it is noticeable, especially in photographs. Since photos of our models turn them into 1:1 scale, and most people are likely to see your modeling in photos than in person, little details like these can become more important.

Myths About Rail Code

The code of rail doesn't have anything to do with reliability or ease of use. Wheels interface with the rail the exact same way regardless of what code the rail is. Code 100 isn't easier to work with, more durable, less prone to derailments, less susceptible to poor track installation, etc., or any of the many other comments you may see. 

The only exception are models that don't have RP-25 flanges may bottom out on the spikes (especially oversized spikes, molded or otherwise). You may find these on older (early '60s and before), or European models (which are often actually 00 scale), through the '80s. But fixing this is as simple as changing out the wheelsets. This is possible even with locomotives.

The reason there is no difference in use is simply because the only thing that matters is how the wheel rides on the rail head. The wheel primarily contacts the inner railhead, although model wheel treads aren't always cone-shaped like the prototype so sometimes they ride more on the railhead itself. The only difference is how tall the rail is, but that's irrelevant mechanically, unless the wheels have oversized flanges.

Electrically, smaller rail does have a higher degree of voltage drop, for the same reason that a thinner wire does. However, they conduct electricity to the wheelsets in exactly the same way. Sufficient feeders are recommended for redundancy anyway. 

Code 55 or less is more flexible. If you compare it to Code 100 you'll see why. It's much lighter rail. But the mechanical operation is the same.

I'd recommend doing a little research, and you may be surprised and find that even Code 83 is larger than you need. I also found Microengineering Code 70 was less expensive than Atlas Code 100 when building my layout. I do wish I had used more Code 55 for industry tracks, but in photos it appears the yard tracks may be the same size rail as the main tracks.

Pictures from work (CNZR)

I haven't done a whole lot of rail fanning, but when I have, it's often literally "rail" fanning, since there aren't all that many trains running near me. Now that I'm working at CNZR part time, I have a lot of opportunity to do so.

Here's a shot at the start of a Sunday morning work day at Tobey Rd looking toward Hartford.


One of the things you'll notice on a lot of layouts is that the right of way, and scenery around it, is often very uniform. This is true to some degree on a well maintained mainline, especially back in the '50s and earlier. But you'll otherwise find that it's quite variable, in part because of the terrain around it.

Looking the other way, and a little up the line (past the current construction) you'll see that there are a lot of tall weeds. It's hard to tell, but this is in a drainage ditch. The track here is actually in a bit of a depression, you'll note that the ground on both sides is higher. 


If I move up to where that line pole is, you'll see that the weeds are much less, and the ditch has a lot of small puddles of water. 


On the opposite side, looking back towards Hartford again, this side has almost no vegetation (it's in shade all day), It's just dry, but still has a drainage ditch (also dry).


Looking away from Hartford again, the pile of newer ballast is where the other photo was taken. That ballast is there for the ongoing construction, but it also highlights that the scenery also tells a bit of the history of the railroad. 


That's often most clear in things like the ties, in this case where there are a lot of well-worn ties, with some replacements. Again you can see how the ballast varies quite a bit.

One last shot looking toward Hartford.


For earlier eras, we have to rely on photos for details like these. If you're modeling railroading today, though, I highly recommend getting out there and taking a look where you can (safely and legally). I will say that in pictures of New Britain in my era, the track and right of way are much better maintained. This sort of interesting track and scenery almost makes me want to model a later era. 

Almost...

USRA Single Sheathed Box Cars - Coda

I did an overview of the USRA single sheathed box cars here. But it appears Rapido has been sneaky and added another car that I haven't seen discussed much in the usual places yet.

CP 230000 as built in 1920

CP received 3,500 single sheathed box cars in 1920 and 1921 that very closely followed the USRA design. The major differences were the 7/8 Murphy ends, and they had grain hoppers in the floor. Like many other Canadian single sheathed cars they also had grain clips (Rapido calls these siding clips) to help keep the lowest boards from bowing out when loaded with grain.

Rapido's model is accurate for cars from the mid-30s after the grain hoppers were removed, along with receiving Ajax handbrakes and AB brake appliances.

Tichy and Westerfield also have this variation available, and the same commentary applies as before. Both of them can be built with the grain hoppers. I should also point out that Tichy also makes a cement car modification, with hatches in the roof and floor that matches a D&H prototype. Until the Rapido cars are released I can't tell how easy it would be to use the Tichy parts to modify them.

Yes, I've already ordered one...

Oddity in Foresville

 In a recent post I included this photo and mentioned that something looked a bit odd:


Two RDCs at Forestville in September 1956 (McNamara).

When I first saw the photo I thought it was Forestville. And sure enough, that's the notation on the photo as well. But when I looked closer, I questioned that, as something just doesn't look right. (You'd have to know Forestville to spot it.)

It looks like the station has moved. 

Huh?

Here's a birds-eye view of Forestville today:


The current location of the station is No. 1, on the west side of Central St. 

In the photo of the RDCs, the track (labeled No. 2) is between Tom McNamara (the photographer) and the station. The signs and lettering on the RDCs proves the photo is not reversed. In addition to the curve in the street, you can see the hip-roofed building (No. 3) in the background. Furthermore, if the photo was from the other direction, the Pequabuck River would be right in front of the station. 

The station in Tom's photo looks like it's located where I've labeled No. 4 (on the east side of Central St). Tom was standing at the corner of Central St. (you can see the top of the stop sign). 

Forestville is a neighborhood in Bristol that borders Plainville. In addition to the passenger station it's a village that is known for its clocks. Both the Sessions Clock Co, and E.N. Welch Manufacturing were to the east of the passenger station, adjacent to the Freight House.

I've oriented all of these maps and photos so they'll match Tom's photo. The train is westbound, so westbound (Waterbury) is to the right, Plainville to the left (east).

On the valuation map from 1915 it looks the station is on the west side of Central St (where the station is today), but only a gateman's house on the east side where the station is in the photo. 

 


Yep, on the 1884 Sanborn map it's to the west of Central St. which is also where it is in both a 1952 and 1965 aerial photos:


Another clue? The sign for Bristol Paint Factory. Although I can't find a listing for a company with that name in the 1956 City Directory, I do find Bristol Lacquer and Chemical Co. Their address? 

29 Church Ave. Which is right at the corner of Church Ave and Central St. and would be to the right of Tom when he took the picture.

However, the relationship of some of the buildings beyond the station don't look quite right to my eye. The hip-roofed building isn't quite in the correct location. 

There's another clue.

There's a detour sign at the corner.

Could this be a temporary bridge while they rebuild/repair the Central St. bridge? If so, Tom would be standing at the corner of Academy St. and Church Ave. 

The proof is another building. At the very edge of the photo is a building with a sign that ends in "nny's." Sure enough, Johnny's Restaurant was at 164 Central St. It was just south of the railroad tracks, on the east side of Central St. (and the station was on the west side of Central St.) and just prior to the bridge.

Was the Central St. bridge damaged or washed out by the 1955 floods? 

It certainly was. Here's a photo looking down Central St, with Johnny's on the left, and the station off the picture to the right.

Dorothy McBrien, August 1955

You can see the grade crossing and Johnny's. The river is usually just past Johnny's. 

There's a picture by George Cowles over at the Bristol Press showing the remains of the bridge.

Sometime after the flood, the temporary bridge was built and still in use in September, 1956 when the picture was taken by Tom.

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.

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.
