I think the questions here is whether rail passengers, regardless of gender, race, status etc are able to travel in safety, more importantly feeling safe. Our rail companies have a duty to ensure the safety of all rail passengers. When I was travelling regularly to Lancashire some years back I wrote to Arriva asking why the train I went out on only had 2 carriages and we were packed in like sardines whilst when I returned on a Sunday the train was 5 carriages long with only a handful of people on board. They wrote back (and I quote) "our responsibility id passenger safety NOT passenger comfort . . . charming!
Clearly Glenda's experience highlights that safety on trains is not a priority and I am sure her experience is not an isolated one. But I do agree that safety should not mean segregation. Young unaccompanied males, males with learning disabilities, the disabled (I could go on) everyone should be able to travel in safety.
