Slovenská strela is the name of an express train famous for its fast speed, first operated in July 1936 on the route between the Czech capital Prague and the Slovak capital Bratislava。 It originally ran with unique mid-1930s motor units M 290.0 (Tatra 68), which cut the travel time by more than an hour as compared to the then fastest train pulled by a steam engine。 The regular travel time of 4 hours and 18 minutes was not overcome until the 21st century。 The motor units were so fast that they earned their nickname “Slovenská strela” (Slovak for “Slovak Arrow”).
