Not enough to warrant a timetable extension, sorry but it is no different now to five years ago. And rolling stock has been updated with more capacity so we are told.
You see it from your point of view, which is understandable, but every single day of the week I arrive at stations on time, and joe public ambles along, AMT coffee in one hand, laptop bag in the other. Stands by the waiting train, looks at the screen, looks at the train, looks at the screen, looks at the train. Asks the paltform staff if this is their train looks at the screen ,looks at the train.
Gets on the train. Pokes head back through the door, looks at the screen. Asks a different passing member of platform staff if this is their train. Looks at the screen. Finally moves into the carriage.
Then just as train is about to be despatched, someone at one end of the train gets off. Leaves the door open and walks away, now platform staff has to run down platform to shut the door, while this is going on more idiots are trying to work out if this is their train, repeat ad nauseum.
Eventually leave 5 mins late, after all the idiots are on board and then the passengers blame the trains for making them late.
There are more passengers travelling than there were 10 or even 5 years ago (backed up by statistics, if you care to check) and I'm convinced (altough this is possibly not in the public doman) that their collective IQ's are much lower
