Portrait Winterthur
Two generations of trolleybuses during a TVS extra course at the loop Waldegg in 1998
After the now usual trolleybus system was introduced successfully in Lausanne in 1932, other Swiss cities started to be interested in this system. Winterthur was the first city in German-speaking Switzerland, which decided to build a trolleybus. First, the tramway line between Hauptbahnhof (main station) and Wülflingen was replaced, in 1941 the line to Seen was added, which led to a single through route Wülflingen - Hauptbahnhof - Seen (line 2). In 1948, the trolleybus network was expanded by the newly electrified line 3 Hauptbahnhof - Rosenberg. The era of the tram in Winterthur ended in autumn 1951, when the remained tram line 1 Oberwinterthur - Hauptbahnhof - Töss was converted to a trolleybus line. With the circular route to Breite (connected with the line 3), the development of the network stopped in 1960 for several years. The next large expansion followed in 1991, when the line 6 from Hauptbahnhof to Oberseen was opened, hence the network reached its biggest dimensions, which stayed for only four years. The line to Breite (since the 80ies line 4) was taken out of service in 1995, due to road works and later completely deconstructed. After a reorganisation of the bus network in 2006, nowadays there exist three trough routes 1, 2 and 3. The current line 3 was created by connecting the line from Rosenberg with the former line 6 to Oberseen.
