Successful CATS Auxiliary Case Replacement Cutover

Our team, in collaboration with fiber subcontractor TelWare Corporation, successfully completed the Charlotte Area Transit System (CATS) Auxiliary Case Replacement project, receiving final approval from CATS.

The project involved replacing the existing crossing case, establishing a temporary fiber splice to maintain communications, and installing, testing, and commissioning new equipment.

Working around the clock in rotating shifts, our crews coordinated installation and testing activities to complete the cutover and return the system to CATS ahead of schedule.

With the new equipment commissioned and approved, this upgrade supports reliable system operations and safe transit service for the Charlotte community.
