RandstadRail (Dutch pronunciation: [ˈrɑntstɑtˌreːl]) is a tram-train network in the Rotterdam–The Hague metropolitan area in the west of the Netherlands that is jointly operated by HTM Personenvervoer (HTM) and Rotterdamse Elektrische Tram (RET). It connects the cities of Rotterdam, The Hague and Zoetermeer, primarily using former train and existing tram tracks.[2][3]
Named after the Randstad conurbation, the light rail network came into operation in 2006, after regular train services on the Hofpleinlijn and Zoetermeer Stadslijn had been discontinued.[1] The system consists of four routes and serves 73 stations, with a total length of approximately 71 kilometres (44 mi). In 2018, it had a daily ridership of around 125,000 passengers.[1]
