An online report this week indicated that all Amtrak Midwest Corridor trains in Michigan are now being pulled by Siemens SC-44 Charger locomotives.
Chargers have been pulling some Amtrak trains in Michigan for several months, most notably the Blue Water between Chicago and Port Huron.
But the units were slow to be assigned to Wolverine Service between Chicago and Detroit (Pontiac).
The delay in introducing Chargers to the Detroit corridor was due to the need to develop software for positive train control that was compatible with the Incremental Train Control System used on Amtrak-owned tracks between Kalamazoo, Michigan, and Porter, Indiana.
The first Charger to enter revenue service for Amtrak did so on Aug. 24, 2017, on a Hiawatha Service train between Chicago and Milwaukee. The units are not commonly used on corridor trains in Illinois, Wisconsin and Missouri.
The Chargers used by Amtrak in the Midwest were ordered by the Illinois Department of Transportation in conjunction with state transportation agencies in Michigan, Missouri and Wisconsin that also fund Amtrak corridor service.
Amtrak in December 2018 ordered 75 Chargers that will replace GE P42DC locomotives on long-distance trains starting in 2021.
