Gaia Trafikk

Gaia Trafikk is the largest public transportation provider in Bergen, Norway and Os. It was formed by the 1998 merger of Pan Trafikk, the bus company serving northern and southern Bergen, and Bergen Sporvei, the company serving Bergen's inner city. The route network covers most of Bergen, but the western suburbs are serviced by Hardanger Sunnhordlandske Dampskipsselskap (HSD).

Among the fleet of about 300 busses are 8 trolley busses (two of them are dual mode busses), making Bergen the only city in northern Europe to have them.
