Indeed, which is why I asked if it was a habitual problem. Generally, other passengers seems very happy to be accommodating and actively helpful on trains I have been on when people get on with pushchairs and certainly a wheelchair. Often helping to lift pushchairs, help with the parent's luggage etc. Less so with bicycles.
If the story posted about bus drivers refusing to allow wheelchairs to board because "it is too much trouble" are true then that's a bit of a different story
If my experience is anything to go by there are more “scummy mummy” types on buses, who are likely to be difficult…
I don’t mean that to sound snobby, but I’m sure we all know the sort!
