D-DB 51 80 17-92 030-8 Aüe032 ex 11701. From 1954 to 1959 this one was used in one of the most prestigious trains of the era, the F 55/56 "Blauer Enzian". As DB didn't have new series coaches yet, they composed the train of pre-war coaches. The 11701 was used together with refurbished first-class coaches, a restaurant car rebuilt from a 1928 Rheingold coach and the observation car 11700. Koblenz-Lützel, 2020-10-03.
