The Rotterdam Metro is a rapid transit system operated in Rotterdam and surrounding municipalities by RET. The first line, called Noord - Zuidlijn (North - South line) opened in 1968 and ran from Centraal Station to Zuidplein, crossing the river Nieuwe Maas in a tunnel. It was the first metro system to open in the Netherlands. At the time it was also one of the shortest metro lines in the world with a length of only 5.9 kilometers (3.7 mi).
