Drivers seem confident things will run a lot better. The information given to passengers will improve too, hopefully, with less 'on time' trains suddenly disappearing because the inbound/return workings weren't linked up to allow the non-existent train to show as delayed/cancelled automatically. Doing all of that manually was, well, what made all of these things so much worse in recent weeks.
I also hope we no longer need stop orders on trains that cause chaos and confusion for passengers and staff, with drivers able to refuse and then confuse matters more. Of course they can do this because it's their train, so it's not an attack on drivers, rather the fact that the information is then wrong. It just hasn't been possible to wait for confirmation that a driver accepted a stop order before putting information on the screen, and when that has been attempted you end up with trains stopping that aren't shown at all. Just as bad in many cases, as people have taken other trains or left the station to get a bus/taxi or whatever.
Monday requires getting stock into the right positions, but Tuesday onwards will almost certainly be a vast improvement. Perfect? Maybe not. Reliable? I think so. [come back and quote this to me next week!]
