Portland and Western 1853 (formerly known as Southern Pacific 1532) named "Forest Grove", is an EMD SD9m (formerly an EMD SD7R and EMD SD7) that was manufactured in January 1953 by General Motors Electro-Motive Division (EMD) originally for the Southern Pacific Transportation Company. It is also known to be the only EMD SD9m locomotive ever used by the Portland and Western's roster.

History

Construction, delivery and revenue service

Portland and Western 1853 was manufactured in January 1953 and it was delivered to the Southern Pacific Transportation Company that same year in 1953. It began its life as Southern Pacific SD7 #5288.

In 1965, it was renumbered to 2709 under the Southern Pacific's 1965 renumbering scheme, and then renumbered again to 1409.

It was then rebuilt into an EMD SD7R and renumbered to #1532 and was updated with the addition of a huge mars barrel signal light being mounted on it. After being rebuilt with some upgrades, Southern Pacific 1532 continued to serve with the Southern Pacific Transportation Company area throughout most of its life on the Southern Pacific.

Retirement and preservation

Southern Pacific 1532 was originally retired from active service prior to April 1st, 1995, but was unexpectedly reinstated on May 9th, 1995 until being fully retired on May 17th, 1995. Southern Pacific 1532 was later donated to the Willamette and Pacific Railroad (W&P) on July 24th, 1995, and renumbered by the W&P as #1853.

When the Willamette and Pacific Railroad had become part of the Portland and Western Railroad (PNWR), #1853 retained its current number and was given some cosmetic work by painting the PNWR logo on the locomotive, repainting it into Genesee and Wyoming colors and re-lettering it with PNWR lettering before entering service on the Portland and Western Railroad. Sometime during its days on the Portland and Western Railroad, the locomotive was later rebuilt into an EMD SD9m in order to comply with newer EPA regulations and it was officially named by the PNWR as Forest Grove after a city in Oregon of the same name.
