The California Northern Railroad has operated over portions of the former NWP and SP, including the former SP West Valley Line, since 1993. Painted in an attractive green and white scheme, the line’s varied locomotive types included a group of former CNW GP15-1s. The line was acquired by RailAmerica in 2002 and then became a part of Genesee and Wyoming in 2012. Three of the original GP15-1 locomotives were repainted in the current G&W orange and black scheme.

In the mid-1970’s EMD developed the new GP15-1 model in an effort to offer their customers a replacement for their medium sized road switchers which were wearing out. Many railroads (i.e. ATSF, SP & ICG) were rebuilding their older road switchers and EMD wanted to offer them a different option. Unfortunately there weren’t a lot of takers and only 310 units were built for US railroads. This small 1,500 horsepower unit came with a radiator intake section similar in appearance to the special one that EMD was using on the larger SD40/45T-2 models being produced for the Rio Grande and Southern Pacific to alleviate overheating issues in their many tunnels. Railfan’s dubbed these lager units “Tunnel Motors” which led to the smaller GP15-1’s receiving the moniker “Baby Tunnel motors.” Many GP15-1’s remain in service today for major Class 1 railroads, regional railroads and shortlines.
