Great Britain doesn't have an Americans with Disabilities Act. Now, you may say, why would Britain care about Americans with Disabilities. What I mean by this are that conditions for those with disabilities in Britain seem much harsher than in the US. In particular, I will note the public transport system, especially the rail system.
To be clear, Britain does have a
Disability Discrimination Act of 1995. It is just that the requirements that are made of extant systems are much more modest than the US.
The reason I note this is not, fortunately, because anyone in my household is physically disabled, rather because as I and my wife take our 2 year old son out in a stroller, we notice problems that just don't appear in the US. In part this is because we don't use public transport much in the US, but if we were to use rail transport, there would be an elevator to get to the platform at every station. Even where it would not be difficult to provide a ramp, a short staircase is often the only alternative. Sometimes, a long staircase is required, leading to the stroller carry (which is easier than unbuckling and rebuckling, especially if our son is sleeping).
A quick review of the TfL Underground map shows the extent of the problem, only stations with the wheelchair have lifts or are level with the ground.
One could argue this is about economic efficiency, retrofitting hundreds of stations would be expensive. But the relevant value here is not efficiency but equity and inclusion, if economic efficiency were the criteria, one would make almost no accomodations for the disabled.
This is one more case where the buses beat the trains. Buses are a short enough step that manipulating a stroller is not too difficult. They also have better accomodation for wheelchairs than trains, though in four months here, I have only seen one wheelchair on a bus.
"Barely hospitable" is the phrase my wife uses to describe London. Many Underground patrons are quite helpful in lifting one end of the stroller while one of us has the other, it is the infrastructure that is not designed for anyone who who is not fully mobile.
Most of the sidewalks do have curb cuts, though the rough surfaces make wheeling along them less than optimal, but not impossible.
Finally, one must ask about the omnipresent urban slogan: "Mind the Gap". Why can't trains and platforms be level? London has had over a century to get this right on even the deep-tube lines. I understand that the trains in the deep-tubes (e.g. Bakerloo, Piccadilly, Northern) differ from those on the older (e.g. Metropolitan, District, Hamersmith & City) lines, but how hard could it be to make the stations level with the trains they do serve, to minimize if not eliminate the gap. For all of the human energy devoted to installing Mind the Gap signs and making the everpresent announcements, rectifying the original problem would have been warranted, and probably less expensive.
