About the model
This 1940 locomotive model, built for Union Pacific, perfectly captures all key lines of the real-world original. The wheels are configured as 4 leading + 8 coupled + 8 coupled + 4 trailing. Distinctive highlights include the elongated boiler and the attached tender in the carrier's iconic yellow livery. The Big Boy is a static display model set on a 104 cm long track section. The track segments are compatible with COBI® and LEGO® systems.
