Built in 1960 by International for the Boston and Maine, the transfer cars did have a number of similarities to the caboose order of the previous year, however were built specifically for transfer runs. With these cars, we've modified the frame rail down the center of the car. While it does not have the I-Beam, in it's place are slots that will allow metal rods to be inserted to help maintain frame stability. To finish the build you'll need to provide trucks, couplers, and screws. At present there is no interior to this caboose.
