A group of male passengers travelling in a female-only carriage
on New Delhi's new metro system were ordered to do sit-ups on the
platform by the furious women, according to reports.

At least one carriage is reserved for women on every metro train
in the Indian capital, where female residents and tourists have
complained about sexual harassment on public transport for
decades.
The metro has also become severely congested with the lines
expanding into the suburbs over the last year and most regular
carriages packed to capacity.
The Times of India said on Saturday police led a crackdown at a
station in Gurgaon, a booming satellite development on the
outskirts of Delhi, after a series of complaints -- and women
passengers joined in the action.
"Not only were the unruly commuters made to shell out a fine of
250 rupees (5.40 dollars), angry women slapped some of them and
forced them to do sit-ups," the Times reported.
Gurgaon police commissioner S. Deswal, who led the raid, told
the newspaper: "We found many male passengers in the women's coach.
The moment the women saw us, they got the courage to teach the men
a lesson."
"We want our young girls and women to feel confident and safe
while travelling in the Metro," he said.
The Mail Today reported how some of the men in the women's
carriage "had to bear the ignominy of doing sit-ups in public" when
they were caught on at the Guru Dronacharya station on Thursday
evening.
