Rapido was the name of the Canadian National Railway's express passenger train service on the Quebec City-Windsor Corridor. The service was introduced on October 31 1965 on the Montreal-Toronto route. In 1966, service was extended to the Montreal-Quebec City route and later, to other city pairs, including Toronto-Windsor/Sarnia and Toronto-Ottawa.

Rapido was a BBC 2 television show of the late 1980's presented by Antoine de Caunes. The show which would usually go out in an early evening slot, such as 7.30pm on a Wednesday night, featured reports from up and coming new bands linked together with footage of Antoine standing in front of a large Rapido sign on a white background.
