Under a stormy sky in Jasper, Alberta, on September 17, 2002 is GMD SD40-2 5320 leading a westbound train through the yard. This 1979-GMD-built locomotive features the CN-designed comfort cab that provides better collision protection as well as crew comforts such as refrigerators, hot plates and coffeepots. This cab design became a CN signature for a decade and a half, and became the inspiration for all safety cab locomotives built henceforth for service in North America.
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.
