Well the the FOI response I have submitted has come in and I am honestly disgusted by the attitude Northern has! They seem to be branding me as a nuisance and not bothering to investigate it properly.

KeTech, who supply the customer information software for Northern, seem interested in trying to resolve this issue as well but as the contract lies with Northern and not me, any requests to implement changes has to come from them. The last response in the email thread says the following:
What on earth kind of an attitude is this?! I have tried to be as reasonable as possible with Northern and have only chased it to this degree because it seemed to me that they weren't providing any kind of meaningful response. Turns out they weren't even trying to do anything!
I am very angry with Northern about this. Clearly all this 'passenger charter' stuff means nothing to them if they don't implement accessibility improvements. I contacted my MP about this issue at the same time as I opened this thread.
Also just to clarify, I have nothing against either Network Rail or KeTech regarding this problem. They have both been very reasonable to deal with and are just simply unable to do anything about it.
