Fitting of door control for guards. Are these door controls being fitted at every door opening which means a total of 12 door controls per 4 car unit (6 per side)?
How will the guard communicate with the driver? Will the guard have a radio/mobile phone/other similar device so the guard can be anywhere in the unit, even out on the platform, or will it be via plugging into a socket by a door or both? I think via a mobile device is much more flexible and effective.
If a guard is dealing with a passenger when a train arrives at a station, and dealing with a passenger is taking a long time and needs to continue uninterrupted, will the guard be able to instruct the driver to take control of the door closing procedure so the driver can perform the train despatch procedure? I am assuming there will also be the necessary cctv in the cab functioning as in a DOO setup.
