The problem with a single designated exit door is that on super busy trains, if you on the wrong end you'll cause more problems trying to get off through all the people who aren't. Japan has already solved this with a very low tech solution. The right hand side of the door is where people line to to enter, the left hand side is where people exit. As a commuter in the UK that can't remember when my train home was last on time, I find it hard to believe that it's the passenger fault when we are told it's either infrastructure failure or no reason is given. I've switched to the tram train route that's just opened in Sheffield and that is seeing the same problems. Northern trains running late causing a backlog. I really miss Japan's rail system.
