The lighting is provided by maintenance-free LEDs, including the front signal, the tender and the number boards.

"Realistic Sound Experience"

This model offers a rich sound experience, including steam locomotive sounds that vary depending on speed, bell sounds, whistles and the sound of screeching brakes. The acceleration and braking delay can also be controlled digitally. With a strong speaker in the tender and adjustable sound volume, this locomotive will deliver the authentic sounds of a Big Boy.

"Impressive Details and Dimensions"

This model is equipped with many impressive details, such as coupling hooks in the rail clearer at the front and swiveling steam pipes with guided cylinders.

With a length over couplings of 46.5 cm, this model is an impressive addition to your model railway layout.

"Optimal Enjoyment on Your Railroad"

This locomotive can be used on curved rails from a radius of 360 mm, but a larger radius is recommended. Make sure that the dimensions of the long boiler have sufficient distance from rails, signals, overhead line masts and other objects. Due to the great weight of the locomotive, a stable rail is required. Please note that turntables and overhead bridges can only be driven on in drive-through position.
