I body mounted all the couplers with MT 1015's as well as changing out all the trucks on the sleepers. The bus is a resin kit I picked up somewhere (it really should be a cab over school bus, but this one was about as close as I could find). I body mounted the couplers on all the flats as well. This is not the whole train, only what would fit on the display board. I have a few more sleepers and about twice as many flats. It takes three big units to pull it on our Modutrak layout. It runs quite well and is a big draw at the shows.
