"The GE Dash 8-40CW is a 6-axle diesel locomotive built by GE Transportation Systems from 1990 to 1994. It is distinguished from the Dash 8-40C by the addition of a "wide" or "safety" cab. This locomotive model is sometimes referred to as a C40-8W.

The first Dash 8-40CW was delivered the Union Pacific railroad in 1990, in total GE would build 756 Dash 8-40CW , the Dash 8-40CW was succeeded by the GE_Dash_9-44CW in 1994. Like most GE locomotives, the Dash 8-40CW saw continuous upgrades over the course of its production, later model Conrail units were built with split cooling systems for the Turbocharger Intercooler and Engine Cooling (previous Dash 8 series had both on the same cooling system). The later units delivered to Conrail in 1993 and 1994 were equipped with GE's Integrated Function Displays (IFD). The IFDs are LCD displays that provide the engineer with the same information previously provide to him/her by analog gauges, as well as integrating counter and End of Train Device telemetry functions.

Technical:
The Dash 8-40CW is powered by a 4000 horsepower V16 7FDL-16 diesel engine driving a GE GMC187 main alternator. The power generated by the main alternator drove 6 GE 752AG or 752AH Direct Current traction motors, each with a gear ratio of 83:20 and connected to 40 inch wheels which allowed the Dash 8-40CW a maximum speed of 70 mph (110 km/h).

Depending on customer options, the Dash 8-40CW carried approximately 5000 US gallons (18927 L) of diesel fuel, 410 US gal (1,552 L) of lubricating oil, and 380 gallons (1,438 L) of coolant. Like most North American diesel locomotives, the Dash 8-40CW uses normal water for cooling. The Dash 8-40CW has a maximum tractive effort of 108,600 lbf at 11 MPH with the 83:20 gearing. Overall dimensions for the Dash 8-40CW are 70ft 8in in Length, 15ft 4in in Height and 10ft 2 inches in width."

From Atlas' Announcement:

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.
