As the only remaining part of the Trondheim Tramway, it runs from the city centre at St. Olav's Gate, via the suburban area Byåsen to Lian.

The operating company Boreal Bane owns seven Class 8 trams out of the eleven delivered in 1984-85 for the then longer route.

The first was made by engineer Ferdinand Bjerke, who worked for the Norwegian State Railways, on behalf of the company.

Here it would continue in its own right-of-way, as a single track line up Nyveibakken, past Gamle Åsvei to Bygrensen, Breidablikk, turning west at Hoem, Rognheim and to Munkvoll.

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.

The company was also afraid of passengers "leaking" off at Wullumsgården south of the Dyrborg Loop, and walking to Ila.

By terminating at Ilevolden, the company could choose any rolling stock, including the higher 1,200 V current used on the Ekeberg Line of Oslo.

If the city chose to start the rebuilding of track from the current 200 cm (79 in) width, it would allow Graakalbanen to buy wide stock.

Not before Trondhjems og Stridens Sparebank issued a loan of NOK 1.6 million was it possible to continue construction.

At Munkvoll a brick transformer station was built along with a wooden depot with three tracks and capable of nine trams and trailers.

The management felt this was because Munkvoll was not close enough to the recreational areas of Bymarka, and proposed a quick expansion to Ugla.

At the same time, the ticket price was set high compared to the city trams, at NOK 0.60 for adults.

[clarification needed][14] Further expansions to Lian were also considered, but management was skeptical at having two destinations, since they would not create the necessary critical mass.

To finance the line extension, Graakalbanen decided to create a new company; A/S Ugla–Lian was organized in such a way that it would have no expenses, only income.

During the 1950s, the amount of recreational travel to Lian decreased, but this was compensated by increased traffic from new housing built along the line.

[21] To supplement the aging stock, the GB Class 3 single tram and trailer, from Hønefoss Karrosserifabrikk (Høka) was ordered in 1954.

Because of the increased traffic, a new signaling system was introduced in 1957, and a double track was built from Bergsli gate to Ila.

The rolling stock was painted the same yellow and blue, but the coat of arms used by Trondheim Sporvei were not used on Graakalbanen.

However, from 30 June to 19 August 1968, Trondheim Sporvei needed the trams again, and the old Class 1 was back in service.

The terminus at St. Olavs gate was closed, and passengers were no longer offered a heated waiting room.

An accident that occurred on the bottle neck caused substantial damage, and a fixed block signaling system was installed on the whole line.

As part of a four-line network connecting all the major suburbs, a new route was proposed branching off from Munkvoll and running through Kystad, Stavsted, Kolstad to Heimdal.

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.

These include an extension of the line to the harbour area via Olav Trygvasons street and Trondheim Central Station.

A short stretch from St. Olavs gate to nearby Prinsenkrysset, regarded as part of this plan, was given the green light in 2006, the building was supposed to start in 2009, when the Nordre Avlastningsvei (northern bypass) was due to open and supposedly relieve the city centre from car traffic.

As of 2011 it has been decided to build the extension during the summer of 2012 when the city centre's main bus terminal is to be rebuilt[citation needed].

At the same time the whole section of track within the city centre will be rebuilt to meet the requirements of increased traffic and to remedy years of neglect.

It is stated by Gråkallbanen that they seek to modernize their fleet of six vehicles to low-floor, to allow wheelchair users to board the trams.

Furthermore, there have been several calls for an additional light rail scheme based upon the current railway lines running through the town.
