Port Authority of Allegheny County inks control center deal with Union Switch & Signal


Port Authority of Allegheny County (PAAC) March 15 selected Union Switch & Signal to provide a new operations control center (OCC) system that would regulate traffic on the Port Authority’s light rail "T" line.



Under contract terms, US&S will provide material and engineering for the system, which will include centralized light-rail vehicle control, supervisory control and data acquisition (SCADA), closed-circuit TV, security, and voice and data communications functions.



US&S also will provide wayside signaling and control systems for PAAC’s Library Line extension, and the Stage II signaling and control project, which includes reconstructing 12 miles of the Overbrook, Library and Drake lines.



The new OCC will replace an existing system that US&S designed and delivered in the 1980s.
