The line then passes into Overhalla and continues to Øysletta Station (11.99 km or 7.45 mi), before crossing to the north shore Namsen on the 195-meter-long (640 ft) Bertnem Bridge.

It then crosses Namsen on the 89-meter-long (292 ft) Bjøra Bridge and reaches Himo Station (44.92 km or 27.91 mi).

The line then reaches Overhalla Station (25.58 km or 15.89 mi), which has a passing loop and serves the municipal center of Ranemsletta.

An industrial spur then branches off before the main line reaches Skage Station (36.90 km or 22.93 mi), which has a passing loop.

[9] Next the line reaches Grytøya Station (40.55 km or 25.20 mi) before running through the 46-meter-long (151 ft) Vika Tunnel.

[9] Because the line was built during the Great Depression and NSB was experiencing an operating loss for the first time in its history, minimal investments were made in stations and their facilities.

The main architects were Gerhard Fischer and Bjarne F. Baastad, who both worked for the in-house NSB Arkitektkontor.

After complaints, also Skogmo, Skage and Øysletta Stations received cargo expeditions some years after the opening of the line.

[18] The original proposal called for a line directly from Steinkjer via Beitstad to Namsos and from there onwards to Nordland.

[18] In 1884, Nord-Trøndelag County Council appointed a new committee to plan a railway from Stjørdal via Namsos to Vefsn.

[19] Building a railway to Namdalen was seen as important to ease export both of lumber, farm produce and seafood.

[24] In an 1892 report, a line from Trondheim via Beitstad to Namsos was estimated to be 212 kilometers (132 mi) long and would take 6 hours and 40 minutes.

[28] It was further argued that Beitstad did not need a railway as it was connected to the Trondheimsfjord and that a branch line to Namsos would be built anyway.

Conversely, a line from Sunnan via Snåsa to Grong would cost NOK 6.59 million and would be 79.2 kilometers (49.2 mi) long.

In addition, the branch from Grong to Namsos was estimated at 4.28 million and would be 48.4 kilometers (30.1 mi) long.

[29] In 1900, Trondheim Municipal Council promised to grant NOK 75,000 towards the Nordland Line on condition that it run via Snåsa.

On 10 June 1908, Parliament unanimously passed these lines in the Railway Plan of 1908, which included the 79-kilometer-long (49 mi) section from Sunnan via Snåsa to Grong, albeit without a branch to Namsos.

[35] The county stated that they would not grant any district funding to the line unless a branch to Namsos was also passed.

The level of the district grants were subject to public debate, as they would affect the municipal finances for a long period.

The wage differences were opposed by the trade union, who in 1923 demanded the same pay for the same work, which came into effect from that year.

[41] In 1927, Minister of Labor Worm Hirsch Darre-Jenssen of the Conservative Party stopped construction of the line.

He stated that time had run from the line, and that instead a "good road" should be built between Grong and Namsos.

[42] This resulted in an uproar among local politicians, who in unison stated that cars were not a suitable means of transport, particularly for freight.

Both contributed in giving a lower axle load, resulting in only lighter locomotives being able to use the line and reducing train sizes.

Southwards, which had most of the traffic, the railway was 67 kilometers (42 mi) longer than National Road 17, which runs via Beitstad.

[12] Another problem with the line was that it, as a child of a parliamentary compromise, was built with lower standard than was common on railways at the time.

Although the route was good, the use of gravel ballast and substandard rails, resulting in a low axle load.

[7] In 1997, the National Rail Administration proposed demolishing several closed railways, and stated that they would only retain maintenance of the Namsos Line until 2002.

[46] By 2000, the only regular user of the line was Namdal Mølle og Kornsilo, a grain silo in Namsos.

However, the mining company, Heli Utvikling, stated that should they increase their production to the planned 1.5 million tonnes per year, they would again consider Namsos.
