Am I the first female to comment on this thread?
I think it is rubbish, for many reasons, most of which have already been aired. As a very frequent train user, I am more likely to have a man offer to lift my luggage down from the rack, or on/off the train, than be assaulted by him.
On the services I use, most of the passengers are in couples or families anyway, so would obviously have to sit in the non-segregated coach, which would make it more overcrowded due to males who were prohibited from accessing a considerable section of the train. How would people feel having to stand, if they could see that the female coach was half empty?
Very very rarely do I see any incidents where the gender of the perpetrator is a factor - more likely to be an obnoxious young woman shouting obscenities into her phone in my experience!
Even as a frequent Merseyrail traveller, which to be fair has its share of "scallies", their misbehaviour is not directed towards female passengers, but more of the feet-on-seats, abusive language between themselves variety. Of course I don't travel late at night so cannot comment on the situation then.
Jeremy Corbyn lives on another planet. Or doesn't use trains!
