List of metro systems in Europe
The following list of metro systems in Europe is ordered alphabetically by country and city. Although the term metro is widespread in Europe, there are also other names for rapid transit systems, such as subway, underground, tube, T-bane, tunnelbana or U-Bahn. The list contains systems that can be defined as rapid transit with a completely segregated alignment, including light capacity metros, as well as light rail systems with a considerable section with a completely segregated alignment. Systems like these are grouped by Mark Ovenden as "Urban rail systems" in the 2007 version of the book Metro/Transit maps of the world.
