A pair of Soo Line SD40-2’s idle in the servicing area at Gladstone, Michigan in August, 1986, with a fairly worn GP30 in the background. The 764 was delivered in March, 1973, retired in 2003, and scrapped. The 778, built eight months after the 764, survives today.
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.
