NS #8417 (Patched CR Quality)

First built for Union Pacific in the late 1980's by General Electric, the DASH 8-40C diesel locomotives were identified by an enlarged exhaust stack and the mounting of the dynamic brake grids in a square-like unit behind the cab, which housed an enlarged equipment blower fan. These six-axle, 4,000 hp engines are still in service today in North America.

The 4,000hp Dash 8-40CW was produced by General Electric between 1989 and 1993 as a follow-up to the successful Dash 8-40C locomotive. The most distinguishing feature of this model was the introduction of GE’s version of the wide-nose “North American Safety Cab.” This style of cab would become a common sight on railroads across the country. Four major railroads purchased the Dash 8-40CW in fairly large quantities, including Conrail, CSX, Santa Fe and Union Pacific. Most of these units are still in regular mainline and heavy-haul freight service today. Due to various mergers, they can also be seen operating for new owners Norfolk Southern and BNSF.

The Atlas Master™ Series Gold versions of these locomotives are able to use all of the QSI® Quantum System™ sound features on DC layouts with use of the Atlas Quantum Engineer™.

    Atlas Dash 8-40CW

    Haven't had for very long, but like the model. Surprised by Atlas choice of QSI decoder which, like BLI decoders, seem to move far afield from many other manufacturers standard practices. It took some online research to figure out how to program address (JMRI w/Digitraxx Zephyr wasn't cutting it!)( Audio is also unique. Still have to explore changing some other CVs, but now that I know how...I'm fairly happy with purchase. Only real performance issue is some surprising lack of smoothness just above "creep" speed...goes away quickly on further acceleration. BNSF model has lo headlight, and NS/Conrail has high mounted they should. I view purchase of my pair as reasonable additions to my fleet.
