## About This Content
The mighty Union Pacific Challenger 4-6-6-4 is now available for Train
Simulator, featuring four exciting and challenging scenarios specially created
for the Sherman Hill route.

The stiff gradients of the Wasatch Mountains demanded newer, more powerful and
efficient locomotives, leading to Union Pacific’s chief engineers to design a
4-6-6-4 steam locomotive that utilised two sets of driving wheels each with
their own steam cylinders. The Challenger’s impressive articulated wheel
arrangement made it one of the most successful large steam locomotive designs
ever developed and was considered to be one of the most technologically
advanced of its kind, providing both high horsepower and efficient operations.

Their mammoth weight made the Challenger a regular sight on UP’s heavy
mountainous freight routes but they were also put into service on the
occasional passenger service through mountain territories to California and
Oregon. In total, 252 Challengers were built between 1936 and 1943 by the
American Locomotive Company and Baldwin Locomotive Works, just less than half
for UP.

The Union Pacific Challenger V2.0 for Train Simulator is available in two
liveries – the famous Union Pacific black livery and Union Pacific lined grey
livery. Key features include TSX effects, new smoke and steam particle
emitters, and enhanced cab interior.

The Sherman Hills Add-On (available separately) is required to play the
scenarios included with this Add-On.
