The Munich Transrapid project was being formulatee when I worked in the city for 18 months. The S-Bahn was very good and I used it all the time. I could land at MUC at 23:00 on a Sunday night, be on the train 25 mins later and then 40 mins to the centre and it was ALWAYS there.
However, I expect that they will have to build something faster soon as the car traffic out to there is grim.
