| SP TEBU 1609 at Tucson, Arizona on November 21, 1985, photo by Chuck Zeiler. The SP had 14 of these TEBU's (Tractive Effort Booster Unit, #'s 1600-1613) made from U25B's. The first unit (#1600) was made by Morrison Knudsen, the rest were made by SP. They were generally placed between two modified GP40-2's (modified GP40-2 #'s 7940-7959, SSW #'s 7960-7966), and could transfer fuel between the TEBU's 2900 gallon fuel tank and the GP40-2's, balancing weight between units. They were equipped with dynamic brakes. This one was made from former SP 6713, rebuilt December 1981, assigned UP S316 but retired July 25, 2000 before receiving the number. It is stencilled: EL PASO EP M2 9-85. |
