A manifest train occupies the siding at Standing Rock, with a very recognizable SD40-3 (with its square cab) as lead power. The beginning rebuild of EMD SD40-2 locomotives into the Dash 3, was in 2010. Once a new crew enters the cab and gets a signal to proceed onto the main, unit No. 4289 will use 130,000 lbs of tractive effort to move its freight over the rails.
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.
