SIRT 489 works the west end of Edgewater Yard on the Baltimore & New York Ry. It's a Custom Brass imported model from a few decades back, with some modifications to better match its prototype. The Custom Brass Alco S models were built with All Nation drives and motors.
The 250-ton flat is a Max Gray from 1954, with a GE stator load made from PVC pipe and electrical conduit pieces. It was painted to match a GE stator at the New York State Electric & Gas Jennings power plant. At the time when I was living near there, this former coal burning plant was using ground up, worn-out tires for fuel. It was later converted again, to burn natural gas.
