With the timetable change on 23 May 1982, the Rosenberg line (line 3) was separated from the Breite line (a new line 4). The latter line, which operated as a circle line, was converted back into a diesel bus service on 28 May 1995, and the last remaining traces of its overhead wires disappeared at the end of January 2010.
Meanwhile, in December 2006, lines 3 and 6 were merged into the present line 3.
The present system is made up of the following lines, all of them cross-city routes:
1
Töss–Hauptbahnhof–Oberwinterthur
In rush hour at 6-minute intervals, with 10 trolleybuses.
2
Wülflingen–Hauptbahnhof–Seen
In rush hour at 6-minute intervals, with 11 trolleybuses.
3
Rosenberg–Hauptbahnhof–Oberseen
In rush hour at 7.5-minute intervals, with 10 trolleybuses.

Evolution
The Winterthur trolleybus system was operated initially by conventional length, two-axle vehicles. In 1957, the first five articulated trolleybuses were ordered. They entered service in 1959.
In 1997, Stadtbus Winterthur sold a few trolleybuses to the Romanian city of Timișoara. Other trolleybuses were sold in 1998 to the Bulgarian city of Ruse, and, a year later, to Burgas, also in Bulgaria.
In March 2004, an order for 10 articulated trolleybuses was placed with Solaris Bus & Coach. In November 2005, the first trolleybus in this order was delivered. By the end of 2005, all had entered service; they replaced the Saurer trolleybuses nos. 122–131.
