Built in 1966, this example is one of only eight unique units built for the anticipated Toronto Commuter service and initially wore CN paint. Named the GP40TC (Toronto Commuter), they eventually wore a couple of GO Transit liveries before being sold to Amtrak in 1988. With Amtrak, they wore Phase III and stayed primarily on the eastern half of the country, but some did see service in California. In 2005 they were all rebuilt and reclassified as GP38H-3s, and received Phase V paint. These days they primarily perform work train duties, but can still pinch hit on revenue trains as they retained HEP plants.
