With some problems I had found a very nice B & B and after a real continental breakfast which was served in my room by the hosts I drove to downtown to join a tour with the "Mühlhäuser Straßenbahn".
Only one lady was participating besides me. Wolfgang the driver was excited to have somebody from Canada on board and demonstrated immediately his knowledge of English which he learned by travelling through the United States.
When I asked him about whether cold drinks are served during the ride, he ran away and came back with a warm bottle of Coke. He could not get a cold one.
Then the train started moving and I got my camera ready.
I was really thirsty and gulped down the warm coke before it became hot.

The ride war pretty bumpy and I was surprised how our little road train managed to creep around corners and through narrow streets.
Occasionally the assistant had to pull out posts which prevented that other vehicles enter certain areas.
Pretty girls greeted and waved at us when we passed them. I really liked that.
I learned that it took over two years to get all the required permissions to tour the over 1000 year old city on this route.
The train was built in the Czech Republic and powered by a Japanese diesel engine.
Wolfgang stopped occasionally to allow me to take better pictures. He must have realized that even the built in stabilization system of my camera could not prevent blurry pictures when we drove through the picturesque scenery of Mülhlhausen.
What I had not considered was the effect of the warm coke in my belly. Have you ever shaken a coke bottle and opened it after that? I was feeling like such a bottle and the internal pressure was increasing with each bump in the road.
