graakalbanen was sceptical about the suggestion from thesen, since they would have to rent instead of of track from the city; this would increase the leasing fees from nok 7,000 to 12,000. the company was also afraid of passengers "leaking" off at wullumsgården south of the dyrborg loop, and walking to ila. the dyrborg suggestion would also increase the travel time from torvet to fjellseter from 36 to 57 minutes. however, the city planner's suggestion was cheaper (nok 1,300,000 vs. nok 1,630,000). bøchman recommended bjerke's suggestion, and the board agreed. after the hotel at fjellseter burnt down in 1917, the line was chosen to only terminate at lian.
