I think you miss some of the point though - a "quiet space" on public transport is impractical. Whilst it may make travelling difficult for you, I think you'd struggle to make a case that a lack of such a space is discriminatory.
As for trains which don't have toilets, these tend to be on trains where people make short journeys - so a lack of provision cannot be considered discriminatory.
I have not missed the point at all.
Point is, not that many years ago the idea of unassisted access and accessible toilets for wheelchair users was deemed utterly impractical due to all the modifications of trains and stations required.... altered platforms, lifts etc., new rolling stock. By contrast, proper definition and enforcement of quiet zones esp on longer distance trains merely requires less tolerance of ASB. MUCH cheaper and easier to achieve- IF there was the will to, IF the "invisible" disabilities were accorded the same "status" as visible disabilities.
Toilets and long distance: how do you define long dist? An hour on a train from the top of the valley to Cardiff is a fair stretch especially if first travelling to a toiletless station (as most Valleys stations are). That's also assuming the train is not held up. But the new trains on this route are I understand to be without toilets, on a line which has for a long time now had toilets on trains. Removal of provision.....
No, the real issue is that invisible disabilities don't allow the same level of virtue signalling so get forgotten. Only visible disabilities matter in real life, indeed there's an attitude in some parts of society that a disability doesn't exist unless visible.
Hence I repeat, accessibility is about MUCH more than provision for wheelchair users and some tactile paving. Whilst having those things is good and necessary, it is NOT of itself enough to make a service fully accessible.
Accepting lack of provision for invisible disabilities is no better than expecting a wheelchair user to be consigned to the Guards van. We've (thankfully) moved on from thinking it OK to expect a wheelchair user to be in a Guards van, but the same has not happened for invisible disabilities, nor will it if achieving provision for wheelchair users is conflated with "accessibility. "
Using your argument, we didn't need all the accessibility mods as travelling for wheelchair users was generally possible although difficult (book ahead for assistance etc). All I ask is that invisible disabilities get equitable provision vs visible disabilities.
