A variety of BNSF power sits in Springfield Yard waiting for the call to duty, including most notably an ex-Santa Fe GP50 and an executive SD70MAC. If you squint hard enough, you might be able to see the three units in the background, which include a BNSF SW1500/MP15DC, a BN-painted SW1200, and an ex-BNSF Geep of some sort.
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.
