Run Lola Run

In the beginning of the movie, when Manni leaves the bag (die tasche) on the train, he stops short and tries to retrieve the bag, but the cops hold him back.
This has bothers me. I don’t understand why they are holding him back while he’s struggling and yelling.
Are you not allowed to re-enter a subway train in Germany?
Even if you left your purse or a bag with 100,000 marks in it?

Last year I was in Berlin (where much of the movie was filmed) and their train system is open, as in no turnstiles or fare collectors. You can enter any train, but you’re supposed to have a pass with you at all times. Every now and then there’s a spot check to see if everyone has a pass, and if you don’t, there’s a big fine.
