He was probably pissed off that this lowly woman would confront him on the train about his ticket which was invalid for where he was going, from Brussels to Amsterdam. Knowing enough not to start trouble with a Muslim, the conductor tells him to pay the fare when he arrives at the station, then she walks away.
As they exit the train, the Muslim thug runs up behind the conductor and punches her so hard in the back of her head that she falls to the ground. He then runs away like the filthy piece of pond scum he is. If you enlarge the video when they exit the train you can see that he is a Muslim by his ugly bearded face.
