After the opening of the loop, the line became a much more profitable. Despite being longer, it could still be run with only seven trams; the higher speed up the Singsaker Hill allowed faster travel times. Ridership in November 1955 was up 33 percent since the previous November. Subsequently, the Solhaug bus route operated by Trondheim Bilruter had lost sufficient ridership to be terminated. During rush hour, an extra tram was put into service, decreasing the intervals from six to five minutes. Eventually trailers were also put into use. All this was despite a price increase with 50% in 1955.
