On a foggy night in the New River Gorge, CSX employees guide Amtrak train No. 51, the westward Cardinal, into the station at Prince, West Virginia. On its run from New York to Chicago, the train was delayed by damaged signal wires. Signal systems employ the 'fail safe' principle, meaning the signals are designed to stop train movements when problems arise. In this case, to minimize delays, the CSX dispatcher allowed the train to proceed after the men walked ahead to check for broken rails and other obstructions. The top of the image features traditional signal hardware typical of that installed by CSX predecessor Chesapeake & Ohio. C&O signaling practice favored large cantilever signal bridges used to center the signal heads over the specific tracks on which they governed train movements. Here, the signals for both tracks display the red over red aspect, which indicates "stop."
