Frank Hodina has been busy bashing some parts to build a new tank car. Here are his tips and techniques.
General American built thousands of tank cars used on US railroads. The GATX Type 30 tank cars were built in the late 1920s and early 1930s. The frame was a design improvement that developed in the late 1920s and became known as the Type 30 frame. Tanks followed typical construction and could vary in size by gallon capacity or if it was an insulated tank. Some older tanks were also used on newer frames. For this model, I’m working towards a Type 30 frame with a newer tank and GATX straps and tank anchoring typical of the early 1930s.
The model frame uses two Tangent Scale Models short Type 30 frames. The Tangent frame is lengthened by four feet for an end platform dimension of 35’-10 ½”. I used as much of the ends of the top of one frame and a middle section of another to get the extra four feet. The bottom plate was the opposite with as much of middle between the bolsters being used. This provided an overlapping joint in the frame which was reinforced with styrene.
After lengthening the frame, the assembly was pretty much as per the Tangent instructions. Cal-Scale brake AB system parts and Yarmouth Model Works sill steps were substituted for the kit parts. The saddles at the bolsters were sanded to fit the larger 8000 gallon tank, a resin tank casting done by Tom Madden. As an alternative, an InterMountain tank can be converted for this project.
As this car will be painted for one in food service no warning placards are needed. Instead small route boards were installed. The dome vents were also removed and replaced by one from Owl Mountain Models.
The car is in the paint tray waiting to be painted, but some shiny things on the layout have distracted me. I’ll share a final image soon.
