MBTA at Rochester

Today in Rochester Yard we spotted this MBTA GP-40M (i think). This is a neat looking locomotive! It's got a wide cab, rare for a 4 axle unit (around here anyways), flared SD-45 style radiators and a wide striker plate on the rear end to mate up with the car diaphragms. Oh, yeah and the purple paint! The problem is that while I was shooting the "T" engine the yard crew was switching a couple of MTA cars. They were both "named" cars but the cut was out of range to see what they were. The cars were shoved onto a track with DMM and GWI cars so I would imagine they are heading to Dansville.
