A list like this one and the metro systems that appear in it may always remain somewhat controversial. One reason is that definitions of what a metro is may vary according to whom you ask (a popular definition is here). Differences between commuter rail, metros and trams are increasingly fading as new hybrid trains allow metros to include sections in streets or shared with heavy rail. In other cases, metros have gradually evolved from former tram or rail lines, so it is sometimes difficult to tell the actual length or date of inauguration of the metro system.
