Groping and verbal harassment is an exasperating reality for women using public transportation in this sprawling capital, where 22 million passengers cram onto subways and buses each day. Some men treat women so badly that the subway system has long had ladies-only cars during rush hour, with police segregating the sexes on the platforms.

But that hasn't helped women forced to rely on packed buses, by far the city's most-used form of public transportation - until this week.

Acting on complaints from women's groups, the city rolled out "ladies only" buses, complete with pink signs in the windshields to wave off the men.

As word spreads about the buses, the women seem delighted, while some men forced to wait a few minutes longer have shown their anger. Still others have stumbled on board despite the signs, much to their embarrassment.
