The Komet (German for The Comet) was an international overnight express train service between Germany and Switzerland, which was in operation from 1954 to 2016.

By at least the early 1960s, the Komet was operating seven days a week, and its route had been extended from Basel to Chur, Switzerland.

[5] On 31 May 1987, the Komet was one of the eight initial night services in the then-new EuroCity (EC) network.

On 2 June 1991, the Komet lost its EuroCity status and was reclassified as a German D-Zug (ordinary express train).

Its main, daily route was shortened, to Hamburg–Zurich, and both the Chur and Brig through cars ran only on Fridays (returning on Saturdays, northbound).

[7] In winter 1995/96, the Komet was reclassified as a CityNightLine service, with train numbers EN 470/471.
