 and UP 26 at the Utah State Railroad Museum in Ogden, Utah, UP 18's tender UP 907853, built in 1937, had a long history; first built for use with UP's FEF series steam locomotives before conversion to turbine use, it served as a water tender from the 1970s to 1984 for trains such as the Expo '74 and the American Freedom Train before being donated to the Kansas Railroad Museum, and then acquired by the IRM.Neither of the turbines are reported to be in operable condition, nor are planned to be restored.In October 1962, Union Pacific constructed an experimental GTEL of its own, using a modified ALCO PA-1 as a cab, the chassis of a GN W-1-class electric locomotive (bought for scrap from the Great Northern Railway) as the second unit, and a modified turbine prime mover removed from one of the 50 to 75 series locomotives.
