the second suggestion was from the city planner, trygve thesen, in 1917. he proposed alternative routes. while the upper sections were identical or close to those of bjerke, thesen suggested making a large loop around dyrborg, just west of ila. this was expected to be the immediate growth area for the city, and would give an improved passenger base for the line. it would, however, increase the travel distance to the upper sections. the city planner presumed that the section within the city limit would be built by the municipal trondhjems elektricitetsværk og sporvei, while the section in strinda would be built by the new company. this would cost the city , while it would cost the company nok 413,000.
