- W179601122 abstract "Not as famous in railroad circles as nearby Cajon Pass and Tehachapi, Beaumont Hill has posed a challenge to the Southern Pacific's (and now Union Pacific's) Sunset Route for 125 years. With a 1.0% grade climb and a 2.0% descent, Beaumont meets the requirements for a heavy-grade challenge. The descent takes trains into the Salton Sink, a depression that is below sea level. Helper locomotives are based in Beaumont, which gives the hill its name. The geographically accurate term is San Gorgonio Pass, a saddle between the San Bernardino Mountains on the north and the San Jacinto Mountains to the south. In the early 1950s, steam locomotives and short sidings began to be replaced by diesel locomotives and long sidings. The article describes that switchover and has historic photos of the transition. Included is a layout of the sidings and signals from 1956." @default.
