The EMD SD45T-2R was a rebuild from EMD SD45T-2 diesel locomotives that were originally built between February 1972 and June 1975 for the Southern Pacific Transportation Company and the St. Louis Southwestern Railway (also known as the "Cotton Belt Route").[1][2][3][4]

History[edit]

Starting in the 1977, the Southern Pacific Transportation Company and the St. Louis Southwestern Railway (also known as the "Cotton Belt Route") had began rebuilding the majority of their EMD SD45T-2 locomotives into what had became the EMD SD45T-2R.[3][4] Both railroads had rebuilt a total of 126 of their EMD SD45T-2 locomotives into EMD SD45T-2R locomotives, which left a total of 121 EMD SD45T-2 un-rebuilt and they were all renumbered as 6793-6832, 6834-6868 and 6869-6892.[2][3][4]

Only one EMD SD45T-2R has survived into preservation while the rest are still in service to this day:
