Many Transport for London maps, posters, etc. show a wheelchair symbol, indicating that access from the street to the station platform is "step free". However, the vertical step and horizontal gap from the platform to the train can be up to 323mm (12.7 inches) for the step and up to a 253 mm (10 inch) gap, denying wheelchair users the dignity of independent travel.
So, about eight months ago I set about gathering information from various maps, rail station information websites (and actually visiting some platforms with a tape measure) amending a TfL step-free map [see my image below] and, from that, I've drawn up a guide map of lines, stations and accessible toilets - for independent travel by manual wheelchair users. I did this primarily for my own use and amusement but I've been encouraged to share it with other disabled people.
Thank you Lisa for your comment above (I'm honoured you've visited here). I questioned myself about whether I should put in those "odd" stations - such as Earls Court - where there may be access on one platform, but not for the other platform and I decided against including it; on the grounds that the station is not really accessible for travel. Invariably when I use a station I need to know that I can travel both to that destination and away from it ... and preferably in either direction.
I wanted it uncluttered but I kept the Piccadilly Line in because I wanted to show the potential danger of getting on at either of the Heathrow stations and then finding that you couldn't get off anywhere else! As for the Metropolitan Line, I believe it has the trains but does not yet have any accessible stations feeding it; when its platform at Kings Cross comes on line I'll add it (but I suspect, like the Piccadilly Line, it might look a bit lonely for sometime to come).
I realise that, for those cool athletic wheelchair users who are capable of doing wheelies (or have a PA with them), my map might look over cautious and restrictive - and it is certainly no substitute for the comprehensive TfL step-free map - but I wanted to draw one that could be quickly easily understood by another disabled person travelling independently by manual wheelchair on London Underground, London Overground and DLR (and also, perhaps, that it would indicate the true state of access in London to those with power to improve transport - BoJo, please note). However, the castors on some powered wheelchairs have a diameter as small as 72mm (2.8 inches) which would reduce the access to even fewer stations than I have indicated.
For anyone with an emerging interest in maps of the London Underground (in particular, the alternative ones), if you don't yet know it, you can't miss the following brilliant resources:
And, for those with a wicked sense of humour, don't miss these:
