Milwaukee Road's Structures
A summary of the Tunnels, major Bridges, and Substations of the
Chicago, Milwaukee, St. Paul and Pacific Railroad.
Tunnels
The Milwaukee Road owned a total of 64 tunnels on their railroad.
Fifty one of these were located on the mainline between Chicago and Seattle,
of which two remain in use. The other 13 tunnels were on other lines, with 6 still used by various railroads. By the beginning of 1980, 5 tunnels had been daylighted, 1 was abandoned and another was bypassed. After the system rationalization during March 1980, only two tunnels remained on the slimmed down CMSP&P. Besides their own tunnels, the Milwaukee Road used Union Pacific's tunnel in Spokane, just east of Union Station.

Major Bridges
With over 10,000 route miles during most of its existance, it was natural that the Milwaukee Road had a large number of significant bridges. The following are the ones which I consider to be the most remarkable.

Substations
The western half of the Milwaukee Road mainline between Chicago and Seattle
crossed over 5 mountain ranges. These were the Belt, Rocky, Bitterroot, Saddle and Cascade Mountains. The decision was made to electrify the Rocky Mountain and
Coast Divisions, powered by 28 substations. The first 14 substations were located along the 440 mile section linking Harlowton, MT, with Avery, ID.
On the Coast Division, 216 miles were electrified from Othello to Tacoma,
including 8 stations. The Avery to Othello section was never completed, and substations #15 to #20 were not built.
Even though the power was turned off over 30 years ago, seven of these
substations are still standing.
