Hi
fyi
As a wheelchair user who catches trains every day, for work and leisure, it recently became apparent to me that many wheelchair users are not aware that if they buy tickets at the station (it doesn't seem to be available online, presumably for reasons of proof). you will receive a 50% discount for you and one other adult travelling with you.
This is without the rail card, (which I don't have) and only entitles me to 33% but costs £20. It is a separate discount, which relates to the wheelchair user not using a seat that can then be used by someone else. I've had this discount for many years on a daily basis, for short trips and intercity, but it seems that many people presenting rail cards and/or booking online the are only getting 33%..
I don't personally book assitance either, unless I'm pre-booking for work purposes, as I find it works better for me not to and I usually don't know what time I will be travelling that far in advance anyway. I just to give staff some notice that I am travelling and find it works just fine, although I am not advocating this strategy for everyone (especially anyone in parts of London), as many others don't have the same experience it seems..
Hopefully this information helps someone.
