Yes, we've recently had a large conference - "ticket to travel?" - which looked at accessibility of rail travel in particular.  Wales is notoriously bad beause the infrastructure is so old and so poor anyway.  

Disabled people can't get around independently unless public transport is accessible to them (many disabled people live in poverty so a car isn't something that they can afford.)  Transport is crucial to the whole overarching Independent Living campign.

We had an update from Arriva trains on how they are improving accessibility in partnership with local authorities and other companies supplying stock/upgrading stations...  

Passenger Focus also spoke about their survey results but the key flaw (which they admitted) was that they only interviewed disabiled people who used rail travel, and not all those who can't but would if they could.
