Silver Lake posted:This week I am posting images of yet another rebuild program the UP SW10.
These were started in 1979 and the rebuild program went on to the mid 1980's. UP rebuilt thier older Switchers using parts from retired GP9s . . . Of the 75 total units rebuilt 40 units were sold off to other Railroads after UP retired the class in 1998.
One unit is still on the UP roster the #96 and it is considered part of the Historic collection and switches the Challenger and Centennial at the steam shop in Cheyenne.
This was a good project, in my opinion. They eliminated the higher-maintenance front cooling system by using off-the-shelf parts that could be changed out quickly.
