When visiting Copenhagen the Metro is a safe, fast and easy way to get around. Actualy it was awarded with the prize for the world's best Metro in 2010. All Metro stations are marked with a red M. There are two lines, M1 runs from Vanløse Station to Copenhagen Airport on East Amager, and M2 runs from Vanløse Station to Ørestad on West Amager. Both lines take you through the heart of the city. The trains are driverless and fully automatic, but with Metro stewards on the train. In addition all trains and stations are equipped with CCTV. Metro around the clock The driverless Metro trains operates at four - six minutes' intervals during the day and evening hours and every 15 - 20 minutes during the night. Between Christianshavn and Vanløse the intervals during rush hour are only two minutes. Between 01:00 - 01:30 and 04:00 -04:30 you will have to wait a little longer, as the trains switch from nighttime to daytime operation and vice versa. The City Ring The next extension of the Copenhagen Metro, the City Ring, will feature 17 stations and link the socalled Bridge Quarters of the city with the city centre via an underground tunnel ring. The City Ring will be completed in 2018. Thus you will see a lot of digging and bulding going on in Copenhagen city centre, especially around Kongens Nytorv and City Hall Square.
