Ah, I hadn't read this closely enough, thanks for pointing this out!It reads much more like the driver will both open and close the doors.
Interesting that the drivers will actually be closing the doors, after a 1-2 on the buzzer, and also be required to check the platform train interface using the cameras before they do so. Also doesn't mention the guard actually having to check the PTI before boarding the train and giving the buzzer, just checking the signal.
At which point who is responsible for the safe dispatch of the train if anything goes wrong? It reads like it is to become the drivers responsibility.
Does anyone know if this is this closer to the method of working adopted for Greater Anglia?
To your point about the guard's responsibilities: the document says that after the doors are closed the guard is required to monitor the PTI through the window and can stop the train at any point by pressing the emergency stop switch, which will apply the brakes immediately. This presumably counts sufficiently for the RMT that the guard retains a role in the safe dispatch of the train (and also noting that the agreement includes a requirement for a guard on every train, which is the RMT's general position on retaining guards in a safety-critical role and not converting them to a 100% customer service and revenue protection role). In the event of an accident, I would expect the investigating authorities to look at both the actions of the driver and the guard - the driver has the benefit of CCTV and also has their hand on the power handle, but the guard may hear a shout from passengers or see something through the window. I don't think safe dispatch has to be a single person's responsibility, it's more that where a guard is part of the crew they provide an additional pair of eyes on the situation.
