Is that not the role discription for a train guard duties as it stands ATM & to deal with "incidents" would these trolley hosts not have to have been given Safety Critical training.
Yes, but the guard won't have to do any train duties normally - and will concentrate on commercial interests to make the post viable, which in turn means they keep their job.
But if anything goes wrong, their extra training kicks in - and that's what justifies a higher salary.
You could argue that we have guards who are better positioned to deal with emergencies, yet we have very few emergencies. That will no doubt be used as an argument to get rid of them in the coming years, whereas my idea ensures they keep their job.
I accept some may not want to suddenly have to dish out food and drink (I recall SAS staff hating having to handle money when the airline decided to charge for food/drink on short-haul flights a few years ago) but if it's that or no job at all...
To clarify; I wouldn't expect any changes until we have new stock that is designed solely for DOO. Thus, existing jobs would be safe for quite a long time. It's staff in ticket offices most at risk in the short term, and even that won't happen overnight until we address a number of ticketing issues.
The quickest way to save money quickly is to review how much projects are costing. Staffing issues will take longer to deal with.
