There's nobody in the cab. BNSF remote-control SD40-2 No. 6926 pulls a long string of cars out the east end of the yard. The RCO is way back in the yard using a belt back to control the locomotive. For safety, he must keep a line of sight on the loco at all times.
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.
