A bank holiday, and Network Rail contractors were out doing maintenance on the CCTV system. This is not a recorded-footage security system, but a local, real-time system that enables drivers of one-person-operation trains to see all the doors along the trains and make sure they are clear before shutting the doors and setting off.
