Firstly, why is everyone so keen to rush to board the train as soon as possible. These days, most seats are reserved, and the train's departure time is timetabled, so I don't see that rushing onto the train as soon as possible achieves anything at all other than annoy the people patiently queuing to show their ticket and get on the train.
Secondly - why no bins on stations? The excuse given is always security, although I fail to see why removing the bins helps. I know bombs have been planted in bins in the past, but surely if a terrorist was planning to plant a bomb at a station, they wouldn't get to the station and think "oh, there no bins, I'd better take this bomb home with me again".
