but fate had other plans for gråkallbanen. the trondheim tramway is one of only two in the world, along with the cairo tramway, to use the combination of metre gauge and 2.6 metre-wide cars. this made it practically impossible to sell the trams and finance the 20 new scania buses that trondheim trafikkselskap needed to operate the bus route to lian and lade. in the end the 11 trams were not sold and instead a company owned by 1400 enthusiasts, as gråkallbanen, was created to operate the tram route on the only remaining line, that started in 1990. in 2004 veolia transport's division in norway, veolia transport norge, bought the company and have announced they will invest another nok 10,7 million, after the purchase in improved infrastructure on gråkallbanen. july 1, 2008 the company name changed from as gråkallbanen to veolia transport bane as. since then the company was renamed boreal transport bane as in 2011, boreal transport midt-norge as in 2012 and finally boreal bane as in 2016.
