turntables...

engines wouldnt fit. this piece is designed to turn on the spot and send the car back the way it came. engines would be too long and the drivewheels likely wouldnt make it onto the rollers, which is what makes the table turn.

there have been train ones that do this released, but they were under the chuggington range from plarail. not sure if they can be bought seperately or not
