Amtrak #68 is out of Montreal Central Station with a rare leader on Amtrak ; one of the 8 EMD GP38-H3's in service. Originally a GMD GP40TC, they were built by General Motors Diesel (GMD), for GO Transit in Toronto. Eight units were manufactured between 1966 and 1968. They were built on an enlarged frame to accommodate a head-end power generator. GO Transit sold the fleet to Amtrak in 1988. The units were based in Chicago and used on short-haul trains. The Norfolk Southern rebuilt all eight at its Juniata Shops in Altoona, Pennsylvania during 2005. These are now classed as GP38H-3, and work as maintenance-of-way trains or standby power for Downeaster trains. But due to a power shortage at Albany, Amtrak sent this unit up north.
