To prepare MARTA for changes to its train control system, TRA provides ongoing support to the Train Control Systems Upgrade (TCSU) project, and especially to its business process re-engineering and organizational change management (BPR/OCM) teams, which include both contractor staff and MARTA personnel. TRA worked with MARTA Rail Transportation and TCSU project personnel to ensure that both groups recognized and addressed critical open issues. The TCSU project replaces MARTA’s rail control and supervisory hardware and software, while the Integrated Operations Center (IOC) project constructs a new control center building to house the TCSU-supplied gear (related to rail service), as well as bus and police control functions.
