PROTOTYPE SPECIFIC INFORMATION

In September of 2014, Norfolk Southern purchased 100 ex-Union Pacific SD90MAC locomotives from EMD/Progress Rail to assist in the high-volume traffic that NS was experiencing. As AC traction was being more accepted by the railroad, which previously had relied solely on DC power, the 90MACs fit the new direction of motive power for the railroad.

Starting in 2016, NS began the SD70ACU capital rebuild program using the SD90MAC units as cores. All major components were either overhauled or replaced, including an overhaul of the 710G3C prime mover. Most notable in the rebuild is that from the electrical cabinet forward, all new components were used, including a new ACe style isolated cab with AAR-style control stand. The new electrical cabinet contains Mitsubishi electronics, replacing the 90MAC’s original Siemens equipment.

Later, starting in 2018, Canadian Pacific announced a plan to acquire 30 SD70ACU units from EMD/Progress Rail using their laid-up fleet of SD90MAC locomotives as core units. That number was later increased from 30 to 60. They also acquired 2 ex-Union Pacific units, in 2019.

In September of 2019, CP unveiled two Heritage painted locomotives in the Tuscan and Grey paint schemes; one unit, 7010, using the Canadian Pacific script lettering and the other unit, 7015, utilizing the Roman font. CP has painted 10 units in this scheme, 5 with the script style lettering and 5 with the Roman style lettering.

In November of 2019, CP painted 5 SD70ACU’s into 5 separate military inspired paint schemes. These units commemorate the Army, Navy, Air Force and a special tribute locomotive for D-Day wearing camo and the Allied invasion stripes used on June 6, 1944.

All Canadian Pacific units have been completed in 2020 and can been found plying the rails of Canada and the US, with a few having even reached Mexico!
