Amsterdam Underground
Overview
The Amsterdam Metro network consists of three heavy rail metro lines Oostlijn (53 & 54), Noord-Zuidlijn (52) and two light rail lines Ringlijn (50) and Amstelveenlijn (51). The inner city part, from Central Station to Amstel station is underground. Most of the tracks are (far) above ground level. In 2018 an addition to the underground rail network, the Noord-Zuidlijn (52), opened.
All lines share much of their track (bed) with NS or other GVB tracks. Those tracks should be and are mapped separately.
The Amsterdam Metro lines are operated by GVB.
Here is a map of the Metro network.
All lines are standard gauge, power is provided through a third rail.
