Product info

The image of the locomotive is digitally retouched.

Notes for operating this locomotive: The locomotive can be used on curved track with a radius of 360 mm / 14-3/16" or more. However, we recommend larger radii. Due to the overhang of the long boiler, signals, catenary masts, bridge railings, tunnel portals, etc. must be installed for sufficient clearance on curves. The track must be well mounted due to the heavy weight of the locomotive. The locomotive can only be run through a turntable or transfer table. Products bearing "Union Pacific" are made under trademark license from the Union Pacific Railroad Company.

A freight car set to go with this locomotive can be found in the Trix H0 assortment under item number 24914. This model can be found in an AC version in the Märklin H0 assortment under item number 37997.
