Ulm
There is no flixbus service from Memmingen to Stuttgart. The train runs with a change in Ulm. The German Railways website offered tickets, leaving 8 to 15 minutes for transfers. But over the past month, I came across several posts in the feed criticizing German railways, so instead of a single ticket I took two, increasing the transfer time to one and a half hours. And, in general, he did the right thing.
When the train from Memmingen left exactly on schedule, I relaxed and thought: in vain they slander the Germans, you won’t drink the ordung. But after 30 km, the train stopped at some half-station, the driver said something in German, and the passengers began to leave the car with confused faces. As it turned out, the locomotive broke down. The train got stuck for an indefinite time, blocking the only way (here I was glad that I rode this train, and not the next one, so I got at least half way). They promised to send a bus, but it is not clear when. The only way to get to Ulm on time is a taxi for 60 euros. It's good that I found three fellow travelers to share the fare.
To be fair, the next 4 trips on German trains were uneventful. Only one train was delayed by 25 minutes.
Ulm - a city on the border of Bavaria and Baden-Württemberg, on the Danube River, 120 thousand inhabitants. Known for being the birthplace of Albert Einstein, Germany's tallest cathedral and painted town hall.
