The only two EMD hood units painted in the Daylight scheme, Southern Pacific SD45R 7399 and SD40E 7342, drift through Ansel, California.

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.
