Ladies only cabin is indeed the trend in major cities worldwide.
I am quite shocked that many you guys do not know about it.
Tokyo and indeed major Japan subway/subway and suburban services
have this Ladies’ Car in the morning peak, some in the evening peak
as well. Its feasibility here in Singapore, however, would be at
doubt because of the lesser amount of train cars (6 compared to
Japan’s 8/10/11/12/14/16) and the difference in society
culture.
In selected JR night rapid and Express/Superexpress trains,
there are female only reserved seats. A female passenger just need
to tell the ticket attendant at a station that she wants to take
the female seat and it can be done. The seats are nothing special
(I sat on to try when the train ended its service) but they are
grouped near the staff cabin and have at least four or more seats
of the same type together.
Not to worry that husbands and wives cannot get on the train
together; the other carriages are not male only, right?
Children only cabin, I don’t think its a feasible idea as well,
how can children take care of themselves, as in young ones. They
would end up pressing the emergency buttons every stop.
