Some XC Train Managers can be a bit heavy handed. I was on a packed voyager and the wheelchair space was full of luggage (there was nowhere else for it!) and the TM was adamant luggage couldn't be left there-even though no one in a wheelchair needed the space nor was it booked. So luggage was left in the aisle thus meaning the trolley couldn't get down and the TM was having to climb over it! It was ridiculous. Fortunately common sense prevailed after a TM swap and new one moved all the luggage from the aisle into the wheelchair space!
You're better off pretending the wheelchair space isn't there in terms of luggage.
1. Many years ago I was on the receiving end of photos sent into the company by a disability lobbyist because someone had chosen to put cases there, ironically after I'd already been through checking tickets.
2. If a wheelchair user turns up unexpectedly the delay to the train whilst the mess is sorted out can be significant. If there really is literally nowhere else for the luggage to go chucking it off at an intermediate station often offends, as we have potentially seen in this case.
It isn't a luggage space, you can't use it as such. Do you expect to be allowed to store luggage in the driver's cab or the galley?
We are briefed not to allow storage of luggage in the wheelchair space.
People who place things in the wheelchair space usually do so with a cry of "but there's nowhere else for it to go!"
Suddenly, when faced with their luggage being dumped on the platform when the space is needed, there *must* be somewhere else for it to go, begging the question of "why isn't it there in the first place?".
In the event of any delay being caused as a result of unblocking the wheelchair space, the train manager you refer to will also be held personally responsible for the cost for failing to work their train correctly and the delay minutes in such circumstances are attributed to them.
