SISS maintenance across the GWR network
Planned and corrective maintenance of CCTV, CIS, PA and Help Points at managed stations and depots, with a customer helpdesk, CCTV downloads and the asset database.
Case study
Help Point maintenance support, WAM-GSX board testing and replacement, and Help Point spares.
TDM supports Help Point maintenance for GTR with telent: it tests faulty WAM-GSX boards, replaces those that cannot be repaired economically, and supplies Help Point spares.
Faulty Help Point electronics on the estate need testing, a clear repair or replace decision, and replacement parts to hand.
Each repair job covers one board: TDM tests it, records the fault and replaces the board where repair is not economical. Faults found include a non-functioning power circuit and a faulty modem.
