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.

Union Pacific's gas turbine fleet totalled 55 locomotives. The first turbine, No. 50, was built by Alco-GE in 1948 and was tested extensively on UP in 1949. Although it was painted in Union Pacific colors, the railroad never owned No. 50, but it …

The General Electric steam turbine locomotives were two steam turbine locomotives built by General Electric (GE) for Union Pacific (UP) in 1938. The two units were streamlined, 90 feet 10 inches (27.69 m) in length, capable of producing 2,500 horsepower (1,900 kW), and reputedly able to attain speeds of 125 miles per hour (201 km/h).

The gas turbine locomotive was a follow-up to the rather unsuccessful steam turbine design. In many ways, however, the designs were completely different from a mechanical standpoint. Also known as GTELs (which was short for gas turbine-electric locomotives), Union Pacific was the only Class I railroad to use the design in regular service.

GT3 (Gas Turbine 3) was a prototype mainline gas turbine locomotive built in 1961 by English Electric at its Vulcan Foundry in Newton-le-Willows to investigate the use of its gas turbines in rail traction applications. It followed 18000 and 18100 as gas turbines 1 and 2.

The improvements are expected to extend locomotive life, improve fuel efficiency by 18%, increase reliability by 80% and increase haulage ability by 55%. Wabtec will modernize the locomotives at its plants in the United States and plans to deliver beginning in 2023.

Nov 17, 2016 · Dubbed the GE Evolution Series Tier 4 Locomotive, the first production models of these massive machines began appearing on Union Pacific railroad property in fall 2015. The 432,000-pound 6-axle behemoths have 4,400 traction horsepower and can reach a maximum speed of 70 miles per hour pulling thousands of tons of freight.

Union Pacific No. 80 (also known as the GTEL Coal Burner) was an experimental gas turbine-electric locomotive (GTEL) built by the Union Pacific Railroad (UP) themselves in October 1962.

Aug 5, 2013 · This adage could very well apply to the reintroduction of the gas turbine-electric locomotive (GT-EL) in the USA driven by and fueled by the new abundant supply of shale natural gas brought about by fracking.
