The 33657 Lumber Truck is ready to transport some serious loads across the BRIO World. This long, red semi-truck and detachable trailer features a hidden engine that can be found when the semi-truck cabin is tilted forward, as well as a magnet on the rear of the trailer to connect to any BRIO World wagon. Lift the red trailer cover off to reveal the three wooden log loads stored safely underneath, each with a metallic pin to connect to any magnetic crane in the BRIO World railway.
