Our NameTrain Passenger Train Car Set contains a black engine, two passenger cars (one blue and one green), and red caboose on an 11-1/4" straight piece of track. Individual cars measure about 3" long by 2" high each and have a non-toxic finish. Track is sanded smooth with laser-engraved stripes and is unfinished. All pieces are crafted from locally sourced, sustainably harvested hard maple and are compatible with our and other wooden railway systems.
