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.
