The EMD E8 is a 2,250-horsepower (1,678 kW), A1A-A1A passenger-train locomotive built by General Motors' Electro-Motive Division (EMD) of La Grange, Illinois.A total of 450 cab versions, or E8As, were built from August 1949 to January 1954, 447 for the U.S. and 3 for Canada. 46 E8Bs were built from December 1949 to January 1954, all for the U.S.
The Atchison, Topeka and Santa Fe Railway (reporting mark ATSF), often referred to as the Santa Fe or AT&SF, was one of the largest Class 1 railroads in the United States between 1859 and 1996. [ 1 ] The Santa Fe was a pioneer in intermodal freight transport ; at various times, it operated an airline, the short-lived Santa Fe Skyway, and the ...

He developed the battery to be the battery of choice [22] for electric vehicles, which were the preferred transportation mode in the early 1900s (followed by gasoline and steam). Edison's batteries had a significantly higher energy density than the lead–acid batteries in use at the time, and could be charged in half the time; however, they ...
In the early 1960s the Reading Company sent 14 of their VO-1000s to General Motors Electro-Motive Division to have them rebuilt to SW900 specifications. Unlike the "Beep", these locomotives retained most of their original carbodies.
The energy density (energy/volume) of a new LFP battery as of 2008 was some 14% lower than that of a new LiCoO 2 battery. [46] Since discharge rate is a percentage of battery capacity, a higher rate can be achieved by using a larger battery (more ampere hours) if low-current batteries must be used.
The added "headroom" in power extended the life of mechanical parts, which was a critical issue with early diesel engines in locomotives. The units were built with AAR type B two-axle trucks. As development design locomotives, modifications were frequently made to them to overcome various teething problems; the EMC demonstrators spent ...
This conversion was sometimes performed when the A-unit had been in a collision and rebuilding the cab was not cost-effective. In some rare instances, B-units were converted to incorporate a cab, such as on the Chicago & North Western Railway in the 1970s with some EMD E8 B-units bought from the Union Pacific. The homebuilt cabs were referred ...
