All aboard for some hands-on choo-choo train fun! This four-car wheeled wooden train includes an engine, coal car, box car, and tanker that easily link and unlink with sturdy coupler. Removable cargo boxes fit in the box car and there's a reversible cargo piece so the train can carry coal or gold! The water tank comes apart and fits on the train in different ways, and the box car doors slide open and shut, helping kids three and older to develop fine motor skills and hand-eye coordination. Sturdy wooden construction means this train will be rolling through years of creative playtime.
