[quote user="erikem"][quote user="futuremodal"]  Did Milwaukee also have a wish list plan for Beverly to Boylston, or was electrification the sole solution offered?  [/quote] As for the 2.2% grade between Beverly and Boylston - sounds like a helper district to me. At 18 miles in length, it would have been a piece of cake compared to the Donner Pass line on the Espee. With the existing Coast line electrificatiion, the Milwaukee would have benefitted from max'ing out the capacity of the Doris and Kittitas Substations (i.e. three 2MW MG sets in each). This would have allowed a pair of EF-5's on a WB train to operate in full parallel - and allowed them to approach the 1 hour rating on tractive effort. [/quote] So as far as anyone knows, there were no plans for even a "high" bridge across the Columbia to reduce the 2.2% of Beverly to Boylston?  At 1300' elevation the shortest distance across Sentinal Gap is about a mile and a quarter, a tremendous length for a high (800' above the water) bridge no doubt.  But it would also have reduced the ruling grade from 2.2% to 1.25% at the same 18 miles between Boylston and the river, and would have required a new total realignment from Boylston to Smyrna, where the 1.25% would have begun.  So 30 miles of 1.25% vs 18 miles of 2.2%, with no increase in total rail miles.
