It looks like a copy of Lionels traditional line of enclosed auto carriers abeit that the menards cars are sealed...no way to add a load. Another thing is all flat cars are labeled dttx which is a doublestack container car marking instead of ettx [tri level rack] or bttx [bi-level rack]. The good thing is the cars are sold individually or in a 4 pack with 4 different numbers.
The only question remains is performance! Will the cars be top heavy or weighted on the underframe of the flat car.
