Wow, well after my long weekend in Munich I thought I would pop a short post on here about the U and S bhan. On arrival at the airport I got a ticket to Nordfriedhof for the day and ended up buying a 3 day pass for the rest of my time.
I noticed that not once on all the times I used the S & U bhan did anyone actually check I had a ticket or are there any barriers at any of the tube stations? Is everyone from Munich so trustworthy that they aren't needed?
I hasten to add I always had a valid ticket, but this system seems it could be open to abuse?
