Lionel created special taller mounting plates for the trucks for this car. The reason for this was that these plates also held the ends of the bulkheads in place and the bulkhead angle bars latched into a stake hole. Each bulkhead has a brake wheel. This is in addition to the regular brake wheel that is mounted on the chassis.
There was no load that was furnished with this car, that came with four No. 2411-4 stakes that were mounted in stake holes equidistant from the bulkheads. There are no variations.
