Weathering Experiments

I'm making some modifications to one of the Rapido X31a box cars that recently arrived. Since I'm going through that process, I want to complete the car, weathering and all. To that end, I've grabbed a spare body (I removed the roof for another project) to attempt to develop a basic process.

Because the X31a cars were built 1934-6 and still in their delivery scheme, I'm using several of Jack Delano's excellent photos as inspiration. I believe these photos are c1942. I also found that there's a book of his railroad pictures, which I immediately added to my Christmas list.

The late '40s/early '50s is still the steam era, so the cars will still weather in a similar manner, so I think these are a good reference for any car that is still in the same paint scheme in my era.


While all of these are useful, I'm focusing on the Pennsy cars, like the X29 in the front.


There are two X31a box cars in this photo.


There's an X29 in the back row, left.

Key Observations

  • The cars in this era don't show a lot of heavy areas of rust like modern cars do.
  • There is a fairly consistent coating of dirt/soot on the dirty cars.
  • There is a range of "dirty." The density of the coating of soot likely has to do with how many months/years a car has gone without a repaint.
  • The roofs tend to be darker.
  • Some of the roofs show paint failure.
  • Some of the wood roofs and running boards show repairs.
  • A few cars (very few) show "chalking" or streaking of the lettering, like the X29 in the third photo.
  • Reefers tend to be cleaner. I know that PFE washed their cars, presumably others did as well.

Base Weathering with Oil Paints

Using this as a guideline, I started with painting along the rivets and other raised elements (including the door) with burnt umber oil paint. I really like working with this medium, and expect that it will form the base of most of my weathering. These photos show the process of working the oils.


You can apply it fairly heavily, since it's easy to remove.



After drying, I was seeing more streaks than I wanted.





I found that removing the excess on the panels with a paper towel was more consistent than a brush.


Here's a few photos on the layout after it had dried.




I tried a number of approaches, all of which worked pretty well. Wetting with (odorless) mineral spirits first, or not. Applying as a wash vs. a thicker application and taking away/thinning with a brush and mineral spirits, and similar variations.

I did find that I preferred upstrokes (from the bottom of the car) with fairly thick paint to apply the color, and down strokes with a damp brush to remove it. This was basically a brush that had been cleaned with mineral spirits and then dried with a paper towel.

I wanted there to be more dirt under the rivets than on top. I used a very fine brush to work on other fine details to ensure they received as much dirt as I wanted. Thinned paint, but not to the point of a wash, on a very fine brush worked well for along the panel lines.

A generous wash in large depressions, such as the door corrugations, did a nice job of providing a random application or dirt. Once dry I used a brush or paper towel to remove excess on the corrugations themselves, particularly along the top.

I wanted a very thin coating to dull the bright white of the lettering.

So far I'm quite happy with the approach, and I can see how it would be easy to do a number of cars at once time.

Just post something. Ha!

So here it is, a week, a week and a half, ummm, nearly two weeks since my last post. After being very consistent all year, my busy schedule has caught up with me. In this case it's been extra hours at all of my work/business endeavors, plus it was my birthday, etc.

That's not to say that I haven't been able to do anything.

After the last post, I was able to finish soldering all of the feeders to the rail at Whiting St. Yard that evening. I have also connected enough under the layout that it's even operating!

AML Modeling buddy Mark Stafford pointed me in the direction of Krone connectors. These are a type of punch block (well, several types) where you can terminate dozens of wires that are then connected to an output wire. In the US we have similar punchdown blocks for phone, and sometimes network systems. These look like a great idea, but getting it done now was more important, so I went ahead with my original plan of wire nuts and T-Tap Connectors.

As is typical, a few models have crossed the desk. I started working on a Wright Track (ex-Smoky Mountain Model Works, potentially available from Southbound Model Works & Decal Co). This has turned out to be quite a challenge, which I'll explain when I get to actually building it. I also cleaned up all the parts for a Resin Car Works DSS&A box car. This will be a fun (and quick) build, just not sure when.

Work at CNZR has been great, naturally. I take a lot of photos like these:


Bloomfield freight house from Wintonbury St.



A frosty morning at Savin Road.
Two ex-B&M Pullman PS-4 50-ton flat cars.


Morning (prior to daylight savings) at Tobey St.

There's also a lot of wildlife, like this deer right near the Copaco cattle chute.


I've seen bobcats, foxes, turkeys, a bear, lots of snakes and frogs, a very large praying mantis, and others I'm probably forgetting.

For fun I sent my daughter a few pictures like these:

There's a frog in this photo.


There are two frogs in this one.

But I'm not sure how much of this I want to keep including things like these on a blog about modeling and my layout. So I've decided to start a group on Facebook where I can post things like this, and also be able to communicate more directly. It's also a place where I can provide more informal updates and previews for what will often end up on the blog.

You can let me know in the comments what you think, and of course on the Facebook Group.

I plan on trying to post to this blog weekly (instead of the three times/week I've been doing for about the last year). I have several posts in progress, but there are a few other priorities right now:

1. Complete the update of the website (I have to switch over by the end of the year).
2. Finish a clinic for the December Hindsight 20/20 meet.
3. Build a website for a friend's model train business - I'm very excited about this one, but can't say anything else yet...

In addition, I'll have work, business, and family things to manage, with Thanksgiving and Christmas right around the corner.

Posts I'm working on:
1. A tour of my buddy Dale's layout.
2. Modifications to a couple of Rapido's X31a models.
3. (Semi) handlaid switches with CVMW tie strips and Proto 87 Stores parts, among others (I have to build two), and Fast Tracks Diamond Line crossing.
4. More work on the Proto S-1, Atlas S-2, Bachmann/W&R 44-tonners, and Crown Custom I-2 locomotives.
5. Upgrading NE-5 and NE-6 cabooses.

So that's where things stand today. It's really adding 40+ additional hours working at the railroad that has restricted the amount of time I have to work on the layout/blog for now. But it's an adjustment, and it's not uncommon for me to get more accomplished when I'm very busy compared to when I have more free time.
