The work will be carried out at Progress Rail’s facilities in Mayfield, Kentucky, and Muncie, Indiana, with the locomotives due for delivery to CP next year.

The project involves complete replacement of traction control systems and fitting the latest EMD cab, which is compliant with current United States Federal Railroad Administration (FRA) crashworthiness standards. Progress Rail says all major components, including the EMD 710 engine, will be remanufactured to ensure optimal performance and reliability.

CP’s fleet of 60 SD90MACs was introduced in 1999 but in recent years the fleet has been stored out-of-use in Winnipeg. CP had offered the locomotives for sale but failed to find a buyer.

The only other operator of SD70ACUs at present is Norfolk Southern (NS), which is rebuilding 110 SD90MACs at its workshops in Altoona, Pennsylvania. More than 70 of these locomotives are now in service with NS.
