The late 1960s and early 1970s saw several countries experimenting with gas turbine trains. The UAC TurboTrain had been in revenue service in the United States and Canada since 1968, with mixed results. [4] British Rail began testing the APT-E in 1972; for a variety of reasons, British Rail did not pursue gas turbine propulsion. [5]
The gas-turbine engine was an 820 kW Turbomeca Turmo IIIF3 gas-turbine Voith hydraulic (derived from a helicopter turbine) and the diesel was a 320 kW Saurer SDHR diesel-mechanical. [2] These trains reached 160 km/h (99 mph). [2] The ETGs entered service in 1971 on the Paris-Caen-Cherbourg.
A 44-ton 1-B-1 experimental gas turbine locomotive designed by R. Tom Sawyer and built in 1952 for testing by the U.S. Army Transportation Corps UP 18, a gas turbine–electric locomotive preserved at the Illinois Railway Museum. A gas turbine locomotive is a type of railway locomotive in which the prime mover is a gas turbine. Several types of ...
GE diagram of a turbine locomotive. 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.
Klimov TV3-117 turboshaft engine. The accessory drive is the large casting on the top. The accessory drive is a gearbox that forms part of a gas turbine engine. [1] Although not part of the engine's core, it drives the accessories – such as generators, pumps for fuel and lubrication oil, air compressors, hydraulic pumps and engine starters – that are otherwise essential for the operation ...
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
It was completed in 1941, and then underwent testing before entering regular service. The Am 4/6 was the first gas turbine – electric locomotive. British Rail 18000 was built by Brown Boveri and delivered in 1949. British Rail 18100 was built by Metropolitan-Vickers and delivered in 1951. A third locomotive, the British Rail GT3, was ...
Combined cycle gas and steam primary movers, with CNG in one tank and water in the other tank, and would be used as a slug behind a diesel electric conventional locomotive. A combined cycle powered locomotive is a patented idea to use two primary movers , a gas turbine with a steam turbine to gain the efficiency of a combined cycle power plant ...
