Berolina was a named passenger train between Warsaw and Berlin via Frankfurt (Oder). Introduced in 1959, it went through a number of iterations, including a short period without a name. Part of the Interexpress network as IEx 242/243 from 1986, it became categorised as EuroCity trains 42 and 43 in 1992. The service was finally replaced by the Berlin-Warszawa-Express in 2002. Berolina is reintroduced as an ICE train from Berlin to Vienna in 2018. The train's name, Berolina, is the New Latin name for Berlin and the allegorical female figure symbolizing the city.
