Additional Information: 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 consistency similar to tar or molasses. To solve this problem, a heater was built into the fuel tanks (and later into fuel tenders) to heat the fuel to 200 °F (93 °C) before feeding it into the turbine. Eventually UP switched from Bunker C to modified No. 6 heavy fuel oil, which contained fewer pollutants and solvents. Soot buildup and blade erosion caused by corrosive ash plagued all of the turbines. Changes to the air intake systems on the production turbine locomotives improved the quality of the air that reached the turbines, which in turn reduced the wear to the turbine blades and increased the turbine's running life. The GTELs were operated into late 1969 and the final two (numbers 18 and 26) were stored at the Cheyenne roundhouse in operating condition until being retired in February 1970. Both were later sent to museums. PrototypeUnion Pacific had long sought the biggest and best locomotives. In the 1930s, a pair of steam turbine locomotives were tried but rejected. Before World War II, Union Pacific had been adding diesels to its roster, but none pulled road freight trains. The idea of using four diesels to equal the power of a steam locomotive was unappealing, so the search began for something bigger. General Electric had been building gas turbines for aircraft and proposed using something similar on a locomotive. Union Pacific thought maintenance costs for a locomotive were largely independent of its power, so a smaller number of more powerful locomotives would save money. Union Pacific decided the best way for the turbine locomotives to realize their potential would be to put them on mainline freight trains. The long runs and relatively high speeds would maximize the turbines' efficiency. After Union Pacific expressed interest, GE built a prototype, GE 101, completed in November 1948. After tests in the Northeast during June 1949, it was renumbered UP 50. Painted in Union Pacific Armour Yellow, UP 50 began a round of tests. Union Pacific never took ownership of this locomotive. This was one of the few internal combustion locomotives in North America that had a cab at each end. The cabs themselves resembled the FA units being built by Alco-GE at that time. The sides of the locomotive had numerous air intake louvers that could be opened and closed in varying patterns. UP 50 was a carbody unit with a B+B-B+B wheel arrangement – four two-axle trucks, with pairs connected by span bolsters. The turbine produced 4,800 hp (3.6 MW), of which 4,500 hp (3.4 MW) was available for traction. This power output was more than double that of diesel-electric units of that era. For starting, the unit's auxiliary diesel generator would power a set of windings in the gas turbine's main generator, causing the generator to rotate. The generator's rotation would begin to spin up the turbine, at which point diesel fuel would be used to start combustion. A steam generator would heat and liquefy the turbine's primary fuel supply (heavy Bunker C oil). When the turbine and fuel oil reached their minimum operating temperatures, the fuel to the turbine would be switched from diesel to the primary fuel. This machine weighed 500,000 lb (230,000 kg) and was over 80 ft (24 m) long. The turbines were delivered in three main groups after extensive testing of the prototype. Union Pacific intended to use the turbines to replace its Big Boy steam locomotives, which were scheduled to be taken out of service. First generation From January 1952 to August 1953, UP received units 51–60, like the prototype but with a cab at only one end to increase fuel capacity. Each cost US$540,000. The locomotive frame carried 7,200 US gallons (27,000 L) of fuel. The GTELs initially pulled freights between Ogden, Utah and Green River, Wyoming, passing through Weber Canyon and Echo Canyon, Utah. In 1954, they began running Ogden-Laramie and, soon after, Ogden-Cheyenne. In 1955 and 1956, 24,000-US-gallon (91,000 L) fuel tenders were added behind the turbines, allowing them to run to Council Bluffs, Iowa. UP 53 was used to test an improved roof-mounted air intake, which proved successful, and locomotives 57-60 were built with this intake. In May 1953, UP 57 was converted to operate on propane using a pressurized tank car as a tender. This fuel burned cleanly and didn't foul the turbine blades as Bunker C oil did but was more difficult to transport and there were safety concerns. The project ended in January 1954 and UP 57 was converted back to Bunker C. No other conversions were done. UP 59 and 60 were used in an experimental 9,000 hp (6,700 kW) double-turbine pair, sharing a fuel tender between them. The trailing turbine sometimes flamed out in tunnels. Despite modifications to minimize these difficulties, the experiment was discontinued, in favor of running additional diesel locomotives with the turbines. The first-generation turbines were retired by June 1964. Second generation 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. Third generation In 1955, Union Pacific ordered a new turbine-electric, the world's most powerful locomotive. Each would be two units plus a fuel tender, rated at 8,500 horsepower (6,300 kW). The A unit contained the control cab and an auxiliary diesel engine generator. The B unit carried the turbine and main generators to provide electricity to the traction motors on both the A and B units. The turbine was a new design, a GE Frame 5 simple-cycle gas turbine with a sixteen-stage compressor, ten combustion chambers and a two-stage turbine. No steam generator was needed to heat and liquify the heavy Bunker C fuel because the tenders were insulated. The original plan was to number these units in the 7000 series but they were numbered 1 to 30. They were delivered to Union Pacific between August 1958 and June 1961. These units were very different from the previous generations, having a wheel arrangement of C-C on each of their units (not including their tenders). The locomotive weighed about 610 tons with a full tender. Continuous tractive effort was 146,000 lb (66,000 kg) with the 65-mile-per-hour (105 km/h) 74:18 gearing; in 1961 tonnage ratings were 6740 on the 0.82% climb west from Cheyenne and 5180 on the 1.14% east from Ogden. The turbines in these units are the most powerful prime movers ever installed in any North American locomotive. With 8,500 hp (6,300 kW) from a single prime mover, these engines set a record that still stands. That rating was claimed[by whom?] to be at 6,000-foot (1,800 m) altitude and 90 °F (32 °C), and in cooler, denser air the turbine itself could exceed 10,000 hp (7,500 kW) if the electrical system could handle it. In 1963, Trains wrote, "The big 8500 h.p. jobs remain under constant scrutiny as UP: (1) jacks some of them up to 10,000 h.p. ratings; (2) considers motorizing their fuel tenders with traction motors..." Lee's book explains that UP tried resetting generator excitation to absorb the higher rating but only on test. The motorized tender sounds unlikely, though Trains mentioned that the turbines' four-month trial to Los Angeles in 1962 ended when "tender wheels were motorized, imposing speed restriction." (The 1961 and 1963 timetables show a 65 mph (105 km/h) limit for all the turbines.) These turbines eventually displaced units 51 to 75. There had been problems with fuel filters clogging on the earlier turbines, so it was decided to filter the fuel before filling the locomotive fuel tanks and the tender. Unlike the earlier turbines, the 8,500 hp (6,300 kW) turbines came with 24,000 US gal (91,000 L) fuel tenders, in addition to the 2,500 US gal (9,500 L) of diesel fuel in the locomotive tank. They had Leslie S-5T-RF air horns on the cab roof (later moved to the mid radiator section of the A unit, in response to ice build-up in the bells). The third generation turbines were all retired by 1970. Retirement Bunker C's cost advantage waned as the plastics industry began to find uses for it and improved cracking techniques allowed the oil, previously considered waste, to be converted to lighter fuel grades. The last run of a gas turbine locomotive took place on December 26, 1969. Their running gear was recycled into the GE U50 series of locomotives. Trucks, traction motors and span bolsters from locomotives 51 to 75 were used in the construction of the U50, and trucks and traction motors from locomotives in the 1 to 30 series were used in the construction of the U50C. Several of the tenders were retained and converted to hold water for maintenance of way purposes and later to be used for Union Pacific's operating steam locomotives: UP 844 and UP 4014.
