Atlas's HO scale Master Silver Series GE Dash 8-40CW captures Union Pacific #9427 in the railroad's iconic Armour Yellow and Harbor Mist Gray with red lettering — the wide-cab GE freight workhorse that helped UP haul intermodal and unit grain trains across the West through the 1990s and 2000s. Standard DC, with the same precision Master Series mechanism Atlas is known for, just minus the factory sound.

Is this DCC-ready?
Yes — this is a standard DC analog model with a DCC-friendly mechanism. A decoder can be added (not included). It will not produce sound; this is a non-sound version.
What's the difference between the Atlas Master Silver and Gold series?
Silver Series is Atlas's standard DC offering (no factory decoder, no sound). Gold Series typically ships with ESU LokSound DCC sound preinstalled. Both share the same body, mechanism quality, and detail level.
Will this run on tight curves?
Atlas recommends a 22" minimum radius. The long six-axle Dash 8-40CW will bind on smaller curves typical of N-scale-style or starter-set HO layouts.
What era is this prototype?
The Dash 8-40CW (wide-cab GE) was built starting December 1989. Union Pacific #9427 dates to the early 1990s and saw service into the 2000s. Suitable for any modern UP layout.
