Three axles on the model are powered. The locomotive and tender are constructed mostly of metal. The running gear is intricately constructed of metal with a partially open bar frame. There is an open view through the running gear. Dual headlights change over with the direction of travel, will work in conventional operation and can be controlled digitally. The oncoming train light is separately controllable. The lamps are designed to be white. Maintenance-free, warm-white LEDs are used for the lighting. The factory-installed smoke generator kit works in conventional operation. The cab is modeled in detail, and the cab lighting is digitally controllable. There is a close-coupler mechanism between the locomotive and tender with a “display case position.” The tender has a close coupling with a guide mechanism and an NEM pocket. The front buffer height conforms to NEM specifications. Intricate smokebox door steps, a hook coupler and air hose for the rear of the tender, and protective piston sleeves are also included.
