Trams operate in dedicated centre-of-road reservation between Jaarbeursplein and the Vasco da Gamalaan stops. Around the Kanaleneiland-Zuid stop, trams operate between two parallel streets in a dedicated right-of-way. History Earlier tram services In Utrecht, there were earlier tram services that existed between 1879 and 1949, after which there was no tram service until the sneltram opened in 1983. Tram service in Utrecht began in 1879 with a horse-drawn tram line running between Utrecht, De Bilt and Zeist. Between 1883 and 1929, steam and horse trams ran between Utrecht and the villages of Jutphaas and Vreeswijk, now part of Nieuwegein. The first electric trams ran in Utrecht in 1906, and later in 1909 from Utrecht to De Bilt and Zeist. In 1921 there were five tram lines. Tram lines connected the city center with suburbs such as , and . With the increase in auto traffic and bus services, city tram service ended in 1938. After being interrupted during the Second World War, tram service to Zeist ended in May 1949. Sneltram timeline The sneltram light rail system was constructed during the late 1970s and early 1980s. There were two branches both opened on 17 December 1983. One branch ran between Moreelsepark (Utrecht city centre) to Nieuwegein-Zuid in the suburb of Nieuwegein as line 100. A second branch ran from Moreelsepark to Doorslag in Nieuwegein as line 101. The operator was Westnederland. On 14 December 1985, line 101 was extended to the Achterveld stop in IJsselstein. In 1994, Midnet took over operation of the sneltram from Westnederland, and lines 100 and 101 were renumbered as 60 and
