We’re back to look at a few more of the cars from the Secret Santa Rail Car Exchange I participated with in 2020. If you are just joining us, take a look at part one of this series to catch up on the what, how, who, and why. We’ll wait for you.

Rail Car Secret Santa 2020 Part 1

Alright, let’s dig in to the next group of cars.

Roadrailer: Trevor’s build for Monty

Trevor drew Monty’s name, and the car he built to gift was perfect for Monty’s fleet. Trevor choose to model one of the more interesting pieces of intermodal equipment to come out of the 1980s, the Roadrailer.

RoadRailers were specialty trailers that could easily be moved from the highway to the rails without having to be loaded onto a flatcar. The technology dates back to the 1950s. The trailers were built with integrated railroad wheelsets that could be lowered into position when the trailer was pulled behind a train. However it was not until the 1980s that the idea finally gained traction.

Modern roadrailers do not include integrated railroad wheels, but ride on regular trucks that do double-duty, serving as articulation points between multiple trailers in a train. Each regular truck is equipped with one fifth wheel at one end and a connector plate at the other end. The connector plate slides into a female receptacle on the rear of the trailer in front and is secured with a steel pin. At the head of a Road Railer train there is an adaptor truck equipped with one fifth wheel and one regular AAR Type “E” or Type “F” automatic coupler. Each semi-trailer has one king pin at each end. Because the truck (bogie) is significantly lighter than a rail flatcar or well-car, roadrailer freight trains are much lighter and therefore are more energy efficient than traditional intermodal trains.

Though the use of road railers has waned in recent years, Triple Crown still uses them. The “TCSZ” on the trailer is the AAR reporting mark for Triple Crown Service. The trailer number beginning with 464 indicates that the trailer was built approximately 1999–2002, and weighs only 1,000 lb (454 kg) more than a regular highway-only trailer.

Frisco Express Reefer: Jeffry’s model for Bradley

Those of us who know Bradley, know he has a bit of a love for the St. Louis–San Francisco Railway, or as it’s more commonly known, the Frisco. Love may be an understatement, I swear he eats sleeps and breaths nothing but Frisco. So when Jeff pulled Bradley’s name, the road choice was obvious.

With the road choice nailed down, the choice of car type came next. Bradley has already modeled a very nice Frisco train depot, so Jeff played into that and built a piece of head end equipment to compliment Brad’s depot. And what head end car is cooler than an express reefer. Pun fully intended.

Express refrigerator cars were used to carry perishable crops like berries and melons to distant markets at passenger train speeds before spoilage could occur. Normally, they were operated at the head end of passenger trains, which required that the cars meet the same design standards as steel postal cars in terms of high speed trucks, passenger car brake systems, air, steam and signal lines, passenger car buffers as well as passenger paint and lettering schemes.

This car was built by American Car & Foundry, AC&F. The car is 50ft in length and featured passenger style trucks and of course is lettered for Bradley’s favorite road, the Frisco. 

Matt’s Northern Pacific Wood Chip Gondola for Jeffry

Matt drew Jeff, and the resulting car is a really nice wood chip gondola. Here is some more info from Matt on his car.

My build was for Jeff Fonda. His railroads and era of choice were Northern Pacific (NP) or Great Northern (GN), and mid to late steam (40’s to 50’s). The first step was to find a prototype, one that hadn’t been modeled already by Brick Model Railroader (BMR) or Brick Train Depot (BTD) – meeting all three of these criteria would prove to be tough! 

In the beginning I quickly realized that both these roads had woodchip gondolas, which was a type of car I personally hadn’t seen done in Lego before (which meant BMR and BTD certainly hadn’t done it). The problem was that the majority of the cars I was seeing were later than Jeff’s chosen build era. I briefly started looking at other types of cars, but since a woodchip hopper had been something I’d wanted to build for a while I came back and searched a bit harder. Eventually I found the NP 52000-52749 series of cars, which were drop-bottom gondolas built in 1937. 

By now you’ve probably seen the photos of the car, and may be thinking, “Matt, don’t you know anything about math? 118837 is not between 52000 and 52749!” You would be correct. These types of wood chip cars, like wood chip cars on many other railroads, were in-house conversions from existing cars. The few 52000 series cars that were converted for wood chip service were renumbered to NP 118500-118540. Now you might think, “OK, but you’re still 297 cars off…” I also found the NP 118800 series of cars, which were very similar 40’ drop-bottom gondolas converted to wood chip service. In my research I learned that these wood chip cars were used in captive service to specific mills and the extensions were to increase capacity were designed by the mills, thus the design varied between each class. 

The resources I found for the 118500 series were very scarce, and the few photos I found showed the cars in 1980 being prepped for retirement and wearing much different livery than they would’ve in the 40’s or 50’s.  I also found very few photos of model cars, and these were low quality and only from the side. The source I had found for the 118800 series cars had a number of very large photos of a very well-detailed model. There were some features of these cars that I knew I wouldn’t be able to get right, so I decided to merge the two designs. The fact that each mill had different designs for the cars that it was served by in my mind lent credibility to my design. 

Once the prototype was settled upon, it was time to design the car! Some of the prominent details that I tried to capture included the corrugated ends and ribs of the gondola, the flat, smooth sides of the extensions, the rods to operate the door mechanisms, and the gap between the floor and the trucks, due to the need for the entire length of the car to be able to dump, which also puts the underbody details on display. 

The widest part of the car ended up being 9-wide since the corrugated ends needed to be an even width (8-wide) and the ribs and upper lip of the gondola extended beyond this. The design is almost entirely SNOTed, with lots of internal structure to hold everything in place securely. (It may have been a bit overbuilt, but that probably helped it get to Illinois in a minimal number of pieces!)

Once the design was done, it was time to order parts and decals. Lately, my preferred method for ordering parts is to make a wanted list on Bricklink, use the auto-select function to automatically generate carts, then order two or three of these carts at a time. This way I don’t have to make a special order for the one or two missing parts if there’s any parts missing from orders, last-minute changes to the design, or if I simply forget a piece. (I ordered all the parts at once for a boxcar I recently built and was missing a single 2×2 tile in the end…) The downside to this method is that I can’t start building it when the parts start arriving (though I still did that anyways).

The last step before shipping it was to photograph the car for my records and to share on social media. Without a dedicated photo area or workspace, this involves dragging furniture around…

Then the last step was to pack it up and ship it out! I’ve heard the motto “if it shakes, it breaks” from the ceramics industry, so I took that advice and packed the box with bubble wrap and paper so that when I shook the box I couldn’t hear movement. As far as I know it didn’t break in transit, so I think it worked!

Lots of paper… and some bubble wrap!

Lastly, here are some more shots of the completed car.

Part 3 Coming Friday

That’s three more cars down, and we still have 5 more models to go. Come back tomorrow to see the next group of cars.
