| Milw 614 at Hoquiam |
The MILW introduced diesel locomotives to Gray's Harbor operations after WWII. Based on a February 2000 Yahoo Group text, James Fredricson, a dispatcher for the NP, reported that on Friday August 21, 1959, the Milwaukee Road had MILW 614 (a SW1200) located at Hoquiam for switcher service.
The first batch of units was built in January 1954 and numbered 1637 to 1642. The remaining diesels, 2020 through 2061 (no. 638 started life as no. 2033), were built in November 1954. All of the 1,200-hp locomotives were renumbered into the 600 series in 1959.
1637 was 614's original number.

I am going to model Milw 1637. I am going to kitbatch this locomotive using an Athearn SW7 Blue Box Edition model.
