Classic Signals Ready to Fall With replacement signals up all along the Columbia Sub, it is only a matter of time before the classic SAL signals go dark.

Leading the F756 local is the former Clinchfield stickered SD40-3, a nice surprise for a rare daylight run down the Columbia Sub.
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.
