Here is a project high on my “bucket list”. A tank car this has some interesting features. The prototype was a General American Tank Car (GATC). The major tank car builders evolved designs during the steam era. Tank car designs evolved with changes in the method of tank construction and frame design. GATC developed the Type-17 around the time of World War I. The frame was composed of two 12″ channels riveted together with steel plates to create a box structure. To this cast steel tank saddle/bolster were riveted to hold the tank and become the connection to the trucks.
The photo shown above is an example of Type-17 design with a later tank design.
The picture shown above shows the bolster casting with it’s poling pockets and support for the running boards. The picture from Tangent Scale Models with used with permission of David Lehlbach The subject of this build is a specific series of 10,000 gallon tank car leased to Union Oil Company. The cars were built in 1922 by GATC.
The picture shown below was from the Arnold Menke collection. It is dated 1938 with no location specified.
I have always liked this 10,000 gallon single compartment car. It has an unusual underframe when compared to the often-modeled AC&F Type-21 or Type-27. In the world of 1/48 modeling, the AC&F designs are about the only design available. General American, Standard Tank Car or Union Tank Car have not been modeled much. The tank features a three horizontal course construction. The tank has a smaller diameter dome (48″) that is 2’9″ high.
You can see the general shape in these two photos. I found a picture on the Tangent Scale Models that shows the bolster really well. The second picture is of an ex-SP&S 10,000 gallon Type-17. Rick Leach took the picture a number of years ago.
LETS GET STARTED:
The model is largely built from styrene. The tank is from a Red Caboose kit. I bought a couple bodies from Bill McClung when he was shutting down the business. The tank body has a cast-on dome that is too large in diameter so I elected to remove that section of the body.
The gray section was salvaged from a spare body. It was spliced into the upper section and reinforced with some .040″ sheet.
The frame is made up of two lengths of Evergreen 1/4″ channel. I used some 1/4″ x 1/8″ strip for hold together the channels. The top of the centersill is “plated” with rivet impressed .010″ sheet. The brass screw is for mounting the coupler. You can see the the bolster assemble installed on the centersill.
The end view shows the basic structure of the bolster and tank saddle. I built the parts from photos and a little guessing. I am not sure how accurate it is but I can live with it.
Well, that is enough for tonight. Next time I will start detailing the tank and dome.
