RailComm Inc. recently installed a yard automation system at Union Pacific Railroad’s Centennial Yard in Fort Worth, Texas.

The railroad will use the system to control and monitor 23 power switch machines. Universal controllers in the yard monitor switch position and track occupancy for individual switches, and wirelessly transmit data back to a central personal computer (PC).

A Domain Operations Controller (DOC®):Yard application displays rail car location, switch position and the train traversing and clearing a route, and provides supervisory control for one of the yard’s crossovers.

The system replaces a PC-based control system with hard-wired communications. Designed to eliminate the need for control wiring and cabling back to a central yard office, the system can be expanded, enabling UP to add workstations and/or field control nodes without interrupting the current system’s operation.

RailComm markets machine-to-machine command, control, communication and information systems to North American freight and passenger railroads, and other industries.
