Extra 1624 East rolls by the interlocking at Reservation, WA on the outskirts of Tacoma at 4:20PM on February 3, 1973. The massive structure in the background is the Milwaukee Road bridge on their line to Chehalis. The Northern Pacific built Reservation Tower as a 31 lever GRS mechanical interlocker. It opened in 1929. The installation of the plant cost $32,000. At the time there were about 75 trains and an equal number of switching moves through the plant each day. It was closed around 1975.
A couple weeks later I was trying to get pictures from the highway bridges near Reservation. The Union Pacific, Northern Pacific, and Great Northern built small yards in the downtown area. As a result when Tacoma grew it had no where to go except up the hillside in the distance. Disk 9
