Norwegian cab ride

The line seems to be fully track circuited and controlled from Trondheim in the south but this seems to end at Eiterstraum with the signals north of there under local control and a member of staff acknowledging each train as it passes. I'm not sure if there is any equivalent of tokenless block in use here.

The line continues to be fully signalled (although under local control) until Skonseng but north of there until Bodø the only signals simply control the entrance to stations/loops with authority to proceed into the next section given either when the train has stopped or by a green flag/light if the train is not stopping. At Fauske you can even see a member of staff changing the points and driving back to the station on a quad bike/snowmobile.

You can see new signals have been installed between Mosjøen and Bodø but not yet in use so it would seem that these videos were filmed in the last days of this method of operation in the north before resignalling.

I'm not quite sure how the token system work in UK, but we don't have tokens per se here in Norway. The TXP at adjacent stations exchange togmelding (directly translated "train message"with each other. TXP at station A call the TXP at station B, ask if he can send train 123. TXP at station B accept, and write down the train number on a piece of paper). When the train arrives at station B, the TXP write down that the train has arrived, and the track is clear.)!

Hope there's a bit more structure than that. There was a similar system in the UK in 1874 which allowed the Thorpe rail accident to occur when incorrect messages were sent, supposedly with the authority of the equivalent of the TXP.

I have seem some photos of the line from about 10 years ago where you can see flags on the platform at stations between Grong and Eiterstraum so it seems that this section used to be controlled in the same way as north from Ørtfjell. Did Eiterstraum to Skonseng used to be controlled this way or have there always been TXP controlled signals on this section?

Also how does Eiterstraum work, are the signals and points there controlled both by the TXP and Trondheim The TXP would need to exchange togmelding with Mosjøen but the section from Trofors would be controlled by Trondheim.

Also in all four videos, the train proceeds at full speed through Bolna without even slowing for the entry signal. Since there is no TXP visible then I guess this is what we would call here "switched out" with Dunderland exchanging togmelding direclty with Lønsdal. In this case then the driver must have been told in advance that there was no TXP on duty at Bolna so they would know not to slow for the entry signal.

Tusen takk, stighetl. I wasn't expecting anyone in Norway to reply so your information us much appreciated.
