Former SOO SD60 6057 was rebuilt by CAD Railway Services (Lachine, QC) and put into service in August 2012.
In April 2013 it was put into storage with the rest of the SD60 and SD60m fleet. The last assignment for 6257 was train 450 between Saratoga and Kenwood. Upon being pulled off that train it was placed in storage at Saratoga where it remains.
