The buses changed the route, and continued from Rosenborg School down Nonnegata to Olav Trygvassons gate in the city centre, but not via the railway station. This was to reduce the travel time to the city from Rosenborg. They had a five-minute headway in rush hour, and eight minutes otherwise. From 16 December the line was driven in both directions. From February 1969 the buses were forced to drive via the station due the concession; this resulted in every other bus taking the former tram route via Singsaker to the city. This gave a 15-minute headway. The other route kept a 7–8 minute headway.
