So far the only rail system I have heard that is 24 hours would
be the New York subway.
Tokyo is nearby, with some trains ending at 1.30am and starting
at 4.30am.
But for a smaller city like us, I don't think night trains will
be feasible for the next few decades; even Hong Kong does not have
trains for night service.
I remember reading a report in the newspaper that SMRT is not
earning a profit through the pretext of having under capacity even
during peak hours.
I suppose that until our trains are congested until people are
squashed like packed sardines, we won't have any night services for
train.
