Important information about the operation of this locomotive: 
This locomotive can be used on curved track with a minimum radius of 360 mm / 14-3/16", but we recommend larger radius curves. Due to the overhang of this locomotive's long boiler, signals, catenary masts, bridge railings, tunnel portals, etc. must be set out further from the curved track for clearance. The track must be well mounted for the high weight of the locomotive.

Numerous separately applied details such as railings, grab irons, signs, piping and appliances underscore the high-quality construction. Yet, the Big Boy comes completely assembled and ready-to-run right out of its protective packaging. The railings and grab irons are modeled using etched sheet metal and fine wire. You have easy access to the DCC connector for installation of a locomotive decoder.

The running gear is another highlight of this model. The frame, wheel sets, and the side and drive rods are all made of metal. The steam lines to the front cylinder group swing with the cylinders. The tender is ready for installation of a sound effects system to be offered later. A close coupling with a guide mechanism connects the locomotive to the tender with a prototypically close spacing.
