What is it?

The MP54AC, also known as MP40PHTC-T4AC, is the latest locomotive in the MPXpress family and uses a pair of Cummins QSK60 60-liter, 16-cylinder engines rated at 2,700 hp each for 5,400 hp total. The source states that it is designed to meet EPA Tier 4 emissions standards, can operate on one engine during low power demand, and was launched with GO Transit; the first prototype was a converted MP40PH-3C unit delivered in late 2015.
