a stop in Kempten. Electrification of the remaining Lindau-Aeschach junction–Lindau-Insel section was completed by December 2021. Operations Long-distance services A Trans-Europ-Express (first class only) service was introduced in the 1969/70 winter timetable, running on the Munich–Lindau–Bregenz–St. Margrethen–St. Gallen–Winterthur–Zurich (lines 56 and 57), called the Bavaria. On the evening of 9 February 1971 a TEE 56 service derailed on the Munich–Zurich route at Aitrang due to speeding, killing 28 people and seriously injuring 42. In 1977, the TEE service was replaced by a "D" (two-class express) service between Zurich and Munich (lines 276 and 277). EuroCity trains have operated on the line since the introduction of the train type in 1987, initially also called the Bavaria. Four pairs of EuroCity trains ran daily between Munich and Zurich, but it has not been given a name since 2002. From the beginning of the 1990s, most EuroCity trains between Munich and Zurich ran via Memmingen to Lindau, with only a single EuroCity train pair running via Kempten (trains 196 and 197). There is also a daily Intercity train pair between Hamburg and Oberstdorf that uses the Buchloe–Immenstadt section of the Buchloe–Lindau line. Another InterCity train runs between Magdeburg and Oberstdorf, using the Buchloe–Lindau line only between Kempten and Immenstadt. The German EuroCity trains on the line were replaced by ICE TD (class 605) diesel multiple units in 2001/2002 on the Munich–Lindau–St. Gallen–Zurich route. These trains from the start, however, had significant defects that were resolved only gradually. The authorisation for the class to run on the line was cancelled from 24 July 2003 and EuroCity trains were reintroduced. Operation of Eurocity services with ETR 610 electric multiple units on this line ended at the timetable change on 13 December 2020. Eurocity services have since been operated with EuroCity-Express (ECE) sets, but only over the upgraded line via Memmingen and therefore only use the Buchloe–Lindau line on the electrified section between Hergatz and Lindau-Aeschach. In long-distance traffic, the Nebelhorn Intercity train pair from Hamburg to Oberstdorf uses the Buchloe–Immenstadt section of the line. The Allgäu Intercity from Oberstdorf to Dortmund runs on the line between Immenstadt and Kempten. Regional services All remaining stations on the Allgäu line have at least hourly services, except Günzach, where trains run only two hours. The DB Regional Express service from Munich to Lindau-Reutin (RE 70) runs every two hours. This is coupled with the RE 76 to Immenstadt,
