Sweden stirs debate with women-only swimming, in nod to Muslims

10. Gosh your own link tells a far more complex tale than you suggest....one car experiment:

One women’s group, the Women’s Municipal League, supported the idea, while a host of others opposed it, stating that it was impractical and unnecessary.

After months of debate, the idea was abandoned. Officials decided that the Hudson Tube women-only cars weren’t that successful after all, and that women didn’t want them anyway.

Said one official in an August 1909 New York Times article:

“Almost an equal number of people (to the advocates of women’s cars) stated that men are the best protection that women have in a crowded car, and that they prefer to ride in cars where men and women are together, that while there are rare occasions when some brute will take advantage of the situation to insult a lady, on the other hand the gentlemen are the best protection the ladies want against such conduct.”

So it did not last, it was not widely supported and according to the article they had one single car on one line. Your post implies many cars as an ongoing policy....
