One of the three ex-Illinois Terminal SD39s purchased by the Guilford organization from the N&W for the Boston & Maine heads up an ex-Conrail GP40 and a native B&M GP40 on train POPY (Portland-Potomac Yard) as it crosses the Connecticut River between Montague and East Deerfield, MA, on a fall day. These SD39s were the first six-motor freight diesels on the B&M roster.
The EMD SD (special duty) series are a strong and reliable kind of locomotive which still serve America's rails today. They have proved themselves reliable by clocking in several million miles of freight service over several decades.
