A variant of the C30-7, 50 GE C30-7As were purchased by Conrail in mid-1984. Externally similar to the GE C30-7 model, six tall hood doors per side (in place of eight) showed it had a 12-cylinder (rather than 16-cylinder) prime mover. Both engines produced 3,000 horsepower (2,200 kW) but the C30-7A's smaller engine used less fuel.
The Dash 7 Series is a line of diesel-electric freight locomotives built by GE Transportation. It replaced the Universal Series in the mid-1970s, and was superseded by the Dash 8 Series in the mid-1980s.
However, for simplicity, many railroads decided to use designations which follow the pattern of the Dash-7 line. Thus, for example, the Dash 8-40C is usually rendered as "C40-8". The "W" suffix indicates the then-optional wide-nose "North American" safety cab. For example, the Santa Fe used the designation "B40-8W" for GE's "Dash 8-40BW".
The GE B30-7 is a diesel-electric locomotive model produced by GE from 1977 to 1983 as part of their Dash 7 Series, featuring a 16 cylinder engine producing 3,000 horsepower. A total of 399 units were produced, including 120 cabless B30-7A units. [1] The B30-7AB/A(B) is an unofficial model. The B30-7 was GE's successor to the U30B.
The GE Dash 8-32B (also classified as B32-8 or D8-32B by some railroad companies) is a 4-axle 3,150 hp (2,350 kW) diesel-electric locomotive built by GE Transportation between 1984 and 1989. It is part of the GE Dash 8 Series of freight locomotives. A total of 49 examples of the Dash 8-32B model were built for North American railroads.
The GE B39-8 is a 4-axle diesel-electric locomotive built by GE Transportation Systems.It is part of the GE Dash 8 Series of freight locomotives. Following the production of the first three units for the Atchison, Topeka and Santa Fe Railway, GE made many mechanical and electrical improvements that were reflected in a redesigned carbody for the remainder of production; these later units are ...
Upon each rebuild, GE classified 8022 (and reclassified 8007) as model C30-8Mi. As rebuilt by New Zealand Rail, DXR8007 was classified by GE as their model C30-7M. In 2007, DXR8022 was one of the locomotives involved in a biofuel trial using a fuel mix of 5 per cent biodiesel and 95 per cent regular diesel over a period of six months. [ 22 ]
The Dash 8-40CM is powered by a 4,000-horsepower (3,000 kW) 7FDL-16 diesel engine driving a GE GMG187 main alternator.The power generated by the main alternator drives six GE 752AG or 752AH direct current traction motors, each with a gear ratio of 83:20 and connected to 40-inch (1,000 mm) wheels which allow the Dash 8-40CM a maximum speed of 70 mph (110 km/h).
