                  many ways, the  is a modified SD90MAC. The SD90MAC struggled 
                  to find a place on US and Canadian Railroads in the 90s. While 
                  Union Pacific and Canadian Pacific purchased many of these engines 
                  – smaller railroads felt alienated from the gigantic prime movers 
                  which limited the SD90MAC’s operational use. In 2016 Norfolk 
                  Southern decided to convert several SD90MACs to s, the 
                  Siemens tech was swapped with Mitsubishi components and the 
                  cab was replaced with the SD70ACe’s cab.
 Canadian 
                  Pacific decided to rebuild their collection of SD90MACs as well. 
                  However instead of going to Norfolk Southern to rebuild these 
                  engines, they reached out to Progress Rail instead. 60 ACUs 
                  were delivered in 2019, and this order contained several heritage 
                  units. These special heritage units were used to commemorate 
                  different branches of the US and Canadian Army.  
                  CP 7020 is painted in NATO green, replicating the standard camouflage 
                  used by Canadian and U.S. military vehicles in temperate areas. 
                  It’s a faithful nod to defense-oriented equipment.CP 7021 features a desert tan paint scheme, accurately representing 
                  vehicles operating in sand-heavy climates.
 CP 7022 is considered the Navy variant. It’s detailed in a grey, 
                  red, and black paint which is inspired by Canadian and American 
                  warships
 CP 7023 is painted in a two-tone grey finish. This closely resembles 
                  colors seen on modern fighter jets.
 CP 6644 proudly wears a camouflage paint scheme based on the 
                  Royal Canadian Air Force Spitfires flown during the D-Day invasion 
                  of Normandy on June 6, 1944.
