It will, at the end of the day, be an additional cost that will have to be passed on to the pax via increased ticket prices.
I am sure all of those demanding impeccable service will be only too happy to pay for it
What compensation do you get when your train breaks down ? or your car leaves you stranded at the side of the road ?
I think it is just too "nanny mentality" UK for words. If the company concerned has performed maintenance in accordance with the manufacturers recommendations, and has a "reasonable" arrangement in place for unscheduled maintenance , both at home base & elsewhere, why, exactly, should you expect to be compensated for something that isn't the companies fault.
I believe most reasonable companies will stump up & accommodate stranded pax, that is reasonable, but more than that strikes me as gross exaggeration.
