Southern are interested in the flexibility: less time to train. An OBS can go anywhere, unlike a guard. You don't need to cancel a train, if there is no OBS. There's also a few seconds less dwell time, important on a heavily trafficked route.
The RMT hate it, because less power to hold us all to ransom. And ASLEF are not keen after the Liverpool guard case, they'd rather let someone on 20k less take all the flak.
A good compromise would be dual door controls, with a Scotail agreement driver opens, OBS closes. OBS on all trains except where operationally necessary, then the driver would take full control. They could have kept old staff on their current rate, and paid new ones £20k double manning countrywide except metro areas, and got them to flog drinks and snacks and clean up at the end.
But they're all such a bunch of kids, bunkered in their own sense of power and self-worth using their customers as cannon fodder, lord knows whether that will happen. The government will probably turn into a busway before we're done.
What a pathetic industry the rail industry is at times.
Driver-opens-guard-closes is already the current method of operation. Train dispatch is a safety-critical task, so Southern would never agree to let OBS participate in dispatch since a main reason for the change to OBS is to get rid of the safety management system. "Safety trained" has no definition under the rules, so they are free to manage "safety trained" staff however they want.
In fact, that's one of the reasons there has been no agreement yet. ASLEF asked for information and assurances regarding training and assessment standards for OBS; Southern initially agreed but then refused to provide it. So far, my understanding from speaking with "fully-qualified" OBS is that the extent of their safety training can be paraphrased as "If anything happens, call the driver, he'll know what to do. If the driver is unavailable, call Control for instructions." Good luck getting through to Control during a major incident, if you even have mobile signal.
ASLEF asked for information and assurances regarding the protocol for clearing the new routes for DOO. Despite initial agreement, SN ignored it and pushed ahead anyway.
Also, ASLEF asked what the "exceptional circumstances" would be that the train would run without an OBS (since SN are keen to say that all former-guard services would have one except in exceptional circumstances) and SN haven't engaged on that. Is normal staff sickness considered "exceptional"? Is intentional understaffing and rest day working "exceptional"? No one knows. They can
roster an OBS to every train, but experience has shown that rosters at SN are rarely fully-covered.
So to say that ASLEF (at least at a local level) has been completely unwilling to negotiate is nonsense. ASLEF has been negotiating since the start of the franchise, but when SN's position is that they're going to move ahead with or without you so you'd better shut up and accept their terms, then that's not good faith. When you actually come to agreements that suddenly become "operationally unworkable" once the company consults the DfT, that's not good faith.
