GE U50
The GE U50 was an eight-axle, diesel-electric locomotive built by GE Rail. They were twin-engined locomotives, combining two diesel engines. Configuration The U50 rode on four two-axle trucks, grouped in pairs linked by span bolsters, giving a wheel arrangement of B+B-B+B. The trucks and bolsters were re-used from scrapped UP turbine locomotives built by GE during the 1950s. The U50 is sometimes inaccurately referred to as the U50D, a back-formation from the U50C name given to the six-axle units. The name is incorrect and was never used by the manufacturer or the railroad. The U50 did not ride on D trucks in any case. It is also sometimes referred to as the U50B, but this is incorrect as well. The U50 was built in response to the Union Pacific Railroad's requirement, issued in the early 1960s, for a 3-unit locomotive intended to replace the turbines. The design was effectively two U25B locomotives on a single frame; each diesel engine and generator powered only the tw ...

GE U50C
The GE U50C was a diesel-electric locomotive built by GE Transportation Systems. Each was powered by two diesel engines. History Forty were built between November 1969 and November 1971 solely for Union Pacific, which numbered them 5000 to 5039. The U50C used a pair of three-axle trucks instead of the four two-axle trucks used on the earlier U50. Again, these were reused trucks, this time from the later, GE turbine locomotives. Development of the U50C was to the same UP specification that produced the EMD DDA40X "Centennial" units—a requirement for a high power locomotive for the railroad's high-speed freight trains. The span-bolster B+B-B+B design was not suited to this service, and the requirement for power at speed rather than low-speed hauling meant six powered axles would be sufficient. The design incorporated extensive weight saving features. GE replaced the 16-cylinder prime movers of the U50 with advanced 12-cylinder engines, lighter and shorter. The engines wer ...

Union Pacific GTELs
The Union Pacific GTELs were a series of gas turbine-electric locomotives built by Alco-GE and General Electric between 1952-1961 and operated by Union Pacific from 1952 to 1970. Background Union Pacific operated the largest fleet of gas turbine-electric locomotives (GTELs) of any railroad in the world. The prototype, UP 50, was the first in a series built by General Electric for Union Pacific's long-haul cargo services and marketed by the Alco-GE partnership until 1953. The prototype was introduced in 1948 and was followed by three series of production locomotives. At one point, Union Pacific said the GTELs hauled more than 10% of the railroad's freight. Fuel economy was poor, for the turbine consumed roughly twice as much fuel as an equally powerful diesel engine. This was initially not a problem, because Union Pacific's turbines burned Bunker C heavy fuel oil that was less expensive than diesel. But this highly viscous fuel is difficult to handle, with a room-temperature con ...

Scrapped Locomotives
Scrap consists of recyclable materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types — typically metal scrap will be crushed, shredded, and sorted using mechanical processes. Scrap recycling is important for creating a more sustainable economy or creating a circular economy, using significantly less energy and having far less environmental impact than producing metal from ore. Metal recycling, especially of structural steel, ships, used manufactured goods, such as vehicles and white goods, is a major industrial activity with complex networks of wrecking yards, sorting facilities and recycling plants. Processing Scrap metal originates both in business and residential environments. Typically a "scrapper" ...

Railway Locomotives Introduced In 1963
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...
