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. Its name reflected the notion that the Comet train and an actual comet can both be described as travelling through the night at high speed. It was introduced in 1954. It became a EuroCity (EC) service upon the launch of the EC network in 1987. It became categorised as CityNightLine (CNL) service in the mid-1990s. With the decision by Deutsche Bahn to terminate all CNL services in December 2016, the Komet ran for the last time on 10–11 December 2016.
