Portland and Western 1501 (also known as Southern Pacific 1530) is an EMD SD7/EMD SD7R that was originally built by General Motors Electro-Motive Division (EMD) for the Southern Pacific Transportation Company in November 1952. [2] It is also known to be the only EMD SD7 locomotive ever used by the Portland and Western's roster. [3]

History

Construction, delivery and revenue service

Portland and Western 1501 was constructed in November 1952 and it was delivered to the Southern Pacific Transportation Company that same year in 1952. [2] It was the Southern Pacific's second EMD SD7 unit that was ever built, it began its life as Southern Pacific SD7 #5280.

In 1965, it was renumbered to 2701 under the Southern Pacific's 1965 renumbering scheme, and then renumbered again to 1401. [2]

It was then rebuilt into an EMD SD7R and renumbered to #1530 and was updated with the addition of a huge mars barrel signal light being mounted on it. [2] After being rebuilt with some upgrades, Southern Pacific 1530 served mostly within the California area throughout most of its days with the Southern Pacific. [2]

1st retirement and preservation

Southern Pacific 1530 was later retired from active service in 1995 and was later donated to the Willamette and Pacific Railroad (W&P) and renumbered by the W&P as #1501. [2] When the Willamette and Pacific Railroad had become part of the Portland and Western Railroad (PNWR), #1501 retained its current number and was given some cosmetic work by painting the PNWR logo on the locomotive and re-lettering it with PNWR lettering before entering service on the Portland and Western Railroad specifically for yard use, [3] #1501 retained its scarlet and gray paint and functional oscillating gyralite during its service on the Portland and Western Railroad. [2]

2nd retirement and current status

The locomotive was officially retired from active service on the Portland and Western Railroad on July 19, 2023. [4] [5] After that, it was later sidelined along with PNWR locomotives #1801, #1803, #1852, #1854 due to Genesee and Wyoming's EPA scandal. [5] [6] But surprisingly, #1501 was eventually acquired by Dieselmotive Company, Inc. (BUGX) in September 2023. [1]

The E9 was the tenth and last model of EMD E-unit and differed from the earlier E8 as built only by the newer engines and a different, flusher-fitting mounting for the headlight glass, the latter being the only visible difference. Since some E8s were fitted with this, it is not a reliable way to distinguish the two. The E9 has two 1,200 hp (895 kW), V12 model 567C engines, each engine driving one generator to power two traction motors.

The EMD SD70 is a series of diesel-electric locomotives produced by the US company Electro-Motive Diesel in response to the GE Dash 9-44CW. Production commenced in late 1992 and since then over 5,700 units have been produced; most of these are the SD70M and SD70MAC models. While the majority of the production was ordered for use in North America, various models of the series have been used worldwide. All locomotives of this series are hood units with C-C trucks, except the SD70ACe-P4 and SD70MACH which have a B1-1B wheel configuration, and the SD70ACe-BB, which has a B-B-B-B wheel arrangement.

The EMD SW1 is a 600-horsepower (450 kW) diesel-electric switcher locomotive built by General Motors' Electro-Motive Corporation between December 1938 and November 1953. Final assembly was at EMD's plant at LaGrange (McCook) Illinois. The SW1 was the second generation of 3,402 cu in (55.75 L) switcher from EMD, succeeding the SC and SW. The most significant change from those earlier models was the use of an engine of EMD's own design, the then-new 567 engine, here in 600 hp (450 kW) V6 form. 661 locomotives of this design were built, with a gap in production between March 1943 and September 1945 due to World War II.
