| Union Pacific 3985, an Alco built 4-6-6-4 Challenger (specifications) articulated steam locomotive, heads eastbound out of Ogden, Utah, and up the 1.14% ruling grade to the summit at Wahsatch, a distance of 65 miles. Seen here in the heart of Weber Canyon (source photo), the 3985 is about to meet 3977 and 3980, two 4-6-6-4 Challengers (source photo) pulling a westbound empty train of Pacific Fruit Express reefer cars down the original main line built in 1869, which has a 1.72% ruling grade. This westbound train will be interchanged with the Southern Pacific Railroad in Ogden, which will transfer it west to California and the farmlands of the San Joaquin Valley. With a 4-8-8-4 Big Boy helper pushing on the rear of the train, UP 3985 works on the second main line built in 1916, next to the Weber River. With a new fireman learning how to fire the locomotive, a seasoned veteran of the Challenger takes a few moments to enjoy the scenery. |
