Our NameTrains Farm Car Set contains a tractor, cow, duck, and dog on an 12" straight piece of track. Individual cars measure about 2.8" 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. Tractor color may vary from that pictured here.
