A so-called special committee was set to look at the matter. With five votes against one, they rejected introducing buses, pointing out that Hovdenak had too optimistic numbers for bus operation. The company was debt-free, and investments in the Singsaker Line would be a natural next step; amortized over 30 years, the upgrade would only cost NOK 59,000 annually. Overhead costs were going to be reduced by 500,000 with the last payment on the debt the same year. On the other hand, buses would inflict an immediate expense of 500,000, while there were sufficient trams to operate the route. In April 1968, the city council voted with 47 against 38 votes to close the line. This was followed second voting some time later, which gave 44 against 41 votes in favor of closing. The last trip, on 21 November 1968, was marked with an original Singsaker tram running the final run. Along with the Singsaker Line, the loop to the railway station was also abandoned. The Singsaker Line was the first part of the Trondheim Tramway to be closed.
