Corbyn calls for "Ladies Only" carriages

A curious side issue in the Labour Party's leadership campaign is his call for carriages for women only. "Ladies Only" compartments were usual on trains in Britain at least until the late 1950.

But why the fresh call for them? Could the real problem be that too many seats are being crammed into too small a space? And could that be due to the fact that a railway carriage in 1955 cost around £6000, compared to £2.6 million today - a real increase by a factor of nine, so every square inch of floor space costs that amount more?

Now there is a question that really does call for an answer, because the 1955 carriage wins hands down in terms of spaciousness, comfort and general ambience.
