That is the hidden charm of rail. The rationing is implicit. Instead of 2000 cars, providing unlimited mobility 24 hours a day you get 20 departures in 2 directions at your local railstation.

Yeah - railways within cities are the future. Look to Mumbai/india - there are 3 main stretches faning out from downtown - and every station are supported by busses/rickshaws/taxies for the local vicinity of the stations. Private driving is rare as the local trains serves 6-7 millions a day ! Hurrah
