A lady on the news said she felt uncomfortable in a carriage with drunk men on a recent journey.
I'd like to see the issue of drunk, rowdy, antisocial behaviour tackled rather than the separation of the passengers.
Therein lies an even more complex issue, the consumption of alcohol on trains can of course be stopped but unfortunately people coming on the train drunk can't be legislated for.
Perhaps we should have a quiet coach, a drunkards coach, a woman only coach, and a children only coach! Corbyn's idea may lead to a bit of a slippery slope of further demands for segregated carriages, meaning that websites which allow seat reservations such as The Trainline would get the feel of a dating site!
