Little History:

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. Units 61 to 75 were delivered beginning in 1954. The outside walkways along the flanks earned it the nickname ''Veranda'' and made it a hybrid of carbody and hood locomotives. The turbine and electrical equipment were about the same, though the side louver air intakes were replaced by the large roof-mounted intake first tested on UP 53. UP 61 was used in multiple-unit control tests with diesels starting in 1958. These tests were successful and eventually all but six of the 4,500 hp (3,400 kW) GTELs were equipped to run with diesels. As tonnage requirements increased, trailing diesel locomotives in multiple unit operation became more commonplace. The Verandas were retired between August 1963 and June 1964.
