Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Southern Pacific Railroad's Pengra Pass route connecting Portland, Oregon with San Francisco, California was completed in 1926. Hauling the trains over the Cascade Mountains would be the answer to problems with huge amounts of curvature and very steep grades dictated by the old line down the Willamette Valley and over the Siskiyou Mountains. Nonetheless, a major helper operation is demanded by the 44 miles of constant grade - the longest anywhere on the former Southern Pacific system - and remember, that would include Donner Pass.show more
