Plans to build an interurban tramway between Frauenfeld and Wil were first made in the early 1850s. The rail line opened in 1887, and was electrified in 1921. Around 1.25 million passengers use the line every year.
Locals call the train "Wilerbähnli" or "Wiler Bähnli".[4]
Operation
Trains run every 30 minutes as S15 service of St. Gallen S-Bahn, requiring 3 trains in operation at once, with trains crossing at the stations of Matzingen and Schweizerhof.
In 2011 the railway company ordered five new ABe4/8 low floor trains from Stadler Rail, to replace the old trains. However, there are plans for a 15 minutes interval in future and therefore some of the old trains will be retained. The first train was delivered in March 2013 and was tested for 3 months. It went into regular service on 26 June 2013.[5][6][7] FWB closed the station at Murkart in 2018 in order to maintain connections with long-distance trains at Frauenfeld.[8]
