I think it should but the car out line fits UK stock. The BMT/IND trains just fit into it while the IRT cars have no problem. Also the train wash you see is two of them put together, the train wash at the Coney Island Yard in Brooklyn, New York is over 600 feet long.
It seem that I have also run into a problem with building the yard, my lap top can't work well with more then one or two full length trains so it will have to wait till I get a new computer. I will continue to add detail, but I won't run many trains on it.
