Hackers on a train - Toying with transportation

"Inspired by the great success in the UK, the de facto monopoly on railway passenger transportation in Austria was recently broken by a new competitor called WESTbahn. Amongst the perks offered to customers are wifi for everyone, prepaid kilometer tickets and the possibility to buy tickets on the train without penalty. Armed with an antenna, a barcode scanner and a ticket for a few rides, I embarked on an epic mission to find out what kinds of fun are to be had with a newly developed system like this. To take away the first question: Yes, yes you can ride for free. As WESTbahn went into service less than a month ago, this talk is somewhat work in progress. In the worst case, you learn how to steal^Wuse other people's tickets and get to hear some amusing tales of train rides, wireless networks and the equipment running on them. Audience participation is allowed, suggested and appreciated."
