Project Description

Project will provide for the comprehensive overhaul of CTA's Public Address System to upgrade the Authority's PA system from antiquated and obsolete technology to modern digital technology with disaster recovery/business continuity solutions, increased capacity, and compliance with NFPA 130. The PA system upgrade will include the upgrade/replacement of the master head-end system at the Control Center and Backup Control Center, and remote systems at each rail station, with ancillary physical infrastructure.
