The fact you talk about “public transport” makes me think you’re British, in which case when you say > We have trains from the 70s on the track, and aside from multiple steps and a gap, there are no places for wheelchairs you’re wrong. The only 1970s train still in widespread use is the HST. These have generally been refitted with wheelchair spaces: it’s in carriage C on a GWR HST, for example. Besides, HSTs are being either replaced or hugely refurbished (power doors etc.) by 2020 - because really serious accessibility regulations come into force then (RVAR). Entire fleets of 80s trains (Pacers) are being scrapped because of this. The British railways are already good for accessibility, and getting much better.
