Steam Big Boy

The “Steam Big Boy” is a steam powered locomotive in Rolling Line. It was included on the release of Rolling Lines on the 6th of April 2018.

The engine uses a 4-8-8-4 wheel configuration and is based off the real-world Union Pacific Big Boy type locomotive. The engine also features animated wheels, side-rods and steam effects which can be activated by using the valves in the cab.

Custom livery support was added on the 6th of May 6, 2019 for update v1.071. On update v2.1.4, the model was revamped with an extended frame and featured the 4014 road number and a bell. Articulation was implemented on version v2.27. Wheels would now curve around turns and the front of the train pivots separately from the boiler.
