The Milwaukee Road - Lines West

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.
