I know how it feels to avoid public transport due to disability. Do you?
Once I was refused access to toilets at a train station because there 'should be one on the train'. The toilet onboard was out of action, disability caused bladder urgency, so I hoiked up my smart skirt and peed in the car park. That was when I could still walk; now I avoid trains entirely. So much for independence.
Here's a news report about Paralympian Anne Wafula Strike who wanted a train toilet but didn't get access to it. If you know how to reach Ms Strike, please send her the link to this post and tell us about it.
[Edit]
Here she is. I've now invited her to this blog post.
