“Setting back a train up to one car” basically means that if you go past a signal or platform by less than one car you can reverse the train. In the past we had to walk through the train and drive it in the wrong direction; if you stayed up front and stuck it into reverse you were sacked.
I’ll say that again, YOU WERE SACKED.
LUL have decided that something that TOps used to lose their job for doing is fine and dandy. It doesn’t matter if we can’t see what’s behind us, just back her up and carry on. This procedure has been in use on the Jubilee Line Extension since it opened but they have Platform Edge Doors so there’s no chance of anyone falling on the track behind you.
OSN no.101 says that if the train is setting back into a platform then the move will carried out by either using the in-cab CCTV or with a member of station staff on the platform at the rear of the train to “make announcements to customers” and “to pass messages from the controller to the train operator”. How you pass messages to someone who’s at the other end of a train isn’t explained.
As we have CCTV on the Central I could be asked to drive a train backwards into a platform with just my trusty, somewhat grainy, often flickery and fuzzy in-cab monitor to guide me . Somehow I can’t see myself doing that with a platform full of passengers.
