In-cab signalling on UK rail lines begins.
This historic sea-change seems to have been underplayed.
The southern section of the East Coast Main Line has been designated as the first piece of UK railway to be converted to in-cab signalling, and the Northern City Line (Finsbury Park to Moorgate) is now running ETCS Level 2 (Both lineside signals AND in-cab sgnals). Linky here .... http:///www.railjournal.com/signalli...ine-in-london/ This should improve headway significantly (& so punctuality) as the NCL is a pair of old single bore tube tunnels which are full of winding curves where each signal is out of sight until you're on top of it, causing drivers to crawl slowly if they're on a yellow (3 Aspect signalling).

I thought the Cambrian Line from Pwllheli to Harlech was the first line to have the ERTMS in cab signalling. IS this something different.

I think the point is that the Cambrian Line was a test bed - a bit like a sandbox where they were able to experiment and fix issues. They were able to experience situations which would have constituted a major incident on a main line, but which can be regarded as 'growing pains' under the protection of the safety system they had in place. Equipment could be assessed and modified.
There were plenty of problems to iron out. According to Wonkpedia.. Quote:
Presumably if the digital side goes lairy they can stop all movements and revert to lineside signalling, but it may cause significant disruption to services. If enough trains stack up it will tail back to Finsbury Park on the Up Side, and this will impact ECML services. So this could be quite embarassing if it goes significantly wrong. As always we wait with baited breath.... John |
I agree the Cambrian Line was a test bed however it has been running succcesfully for several years and the experience has enabled Notwork Rail to proceed with installation on the ECML and other places. I was just questioning the use of the term 'First piece of railway' to be converted. If it said first mainline I think that is more correct.

Yes I agree.
