Buses
Verkehrsbetriebe Karlsruhe and its predecessor have operated bus services since 1911, some with their own vehicles and some operated by subcontractors. The first bus line opened between Mühlburg and Daxlanden on 30 December 1911 and operated for only three months due to large losses. In 1926, another bus service was established to Rüppurr and it continued until 1931. In 1928, the first bus line that still exists today was opened, connecting to the Weiherfeld district. Other bus routes were established over the decades to complement the tram network. Today the bus network has 23 lines and they are organised as feeder services to the tram and Stadtbahn networks. ==References==
