Signaling & Communication (S&C)

Signal systems you can trust, from design to ongoing maintenance.

Safety takes no shortcuts in rail dispatching.

Our centralized dispatching center in Fort Worth, Texas, provides reliable, around-the-clock coverage for short line and commuter railroads across the United States. From managing more than 1,100 crew starts to issuing thousands of track warrants and bulletins each month, we keep rail operations moving safely and efficiently across 2,000 miles of main track.
