Over the course of the past few years, the MARC roster has been entirely expunged of their once mainstay GP40WH-2's. Now in 2013, the last unit standing is the MARC 68, which has been relegated to protect service on the NEC. It now spends most of its days idling away, always running and waiting in case of an emergency, here at the Odenton, MD Maintenance of Way Base.
