East Coast Main Line South Bi-Directional Capability
London has a rail capacity problem, for both freight and passenger trains.
This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).
One of the secondary recommendations of the report is to use the bi-directional capability of the East Coast Main Line to create another freight route through London.
The report explains it like this.
The southern end of the East Coast Main Line, from Kings Cross to Stoke Tunnel (about five miles south of Grantham), is due to be the first part of a national main line to be fully converted to European Train Control System (ETCS) digital signalling.ETCS, because it does not rely on fixed lineside equipment facing one way or another, is bi-directional by nature.
This presents an opportunity for freight to make use of a new routeing at the southern end of the East Coast Main Line, which current signalling and track layout do not permit.
This strategy therefore proposes installing new track layout features that would facilitate this routeing for freight trains, enabling them to take advantage of the bi-directional capability brought about through ETCS deployment.
The main expected change would be the creation of a facing crossover at Bowes Park, to enable southbound freight trains to run onto the Down Enfield Viaduct in the up direction, before continuing onwards to the terminal at Ferme Park or accessing the Gospel Oak-Barking Line at Harringay.
This example shows an advantage of digital in-cab signalling.
This map from cartometro, shows the lines between Bowes Park and Alexandra Palace stations.
Freight trains coming from the North regularly take the Hertford Loop Line and arrive in North London at Bowes Park
Currently, they sneak down the Eastern side of the East Coast Main Line and then take a route across London, which probably uses the North London Line.
What is proposed is that with an extra crossover just South of Bowes Park station, freight trains will crossover and take Enfield Viaduct the wrong way to the Western side Alexandra Palace station.
The Enfield Viaduct is the track taken from Alexandra Palace station to Bowes Park station, by trains going to Enfield. It takes a bit of a loop to the West.
This second map from cartometro, shows the lines South of Alexandra Palace stations.
Note.
- Hornsey is the next station to the South of Alexandra Palace.
- The Eastern side of the East Coast Main Line is crowded with maintenance depots for trains.
- The orange line is the Gospel Oak to Barking Line.
By the use of digital signalling a new freight route through North London can been created.
Conclusion
How many other places can this technique be used?

London has a rail capacity problem, for both freight and passenger trains.
This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).
One of the secondary recommendations of the report is to increase speed through Gospel Oak.
The report explains it like this.
This proposal would see the current 20mph line speeds through Gospel Oak increased, through an upgrade to the junction immediately to the west of the station. Improving the flow of traffic through this critical flat junction, where the North London Line and Gospel Oak-Barking Line meet, would be of benefit for the wider operations and performance of these orbital routes. Freight trains in particular, which run non-stop through Gospel Oak, using all available routes, would see a notable uplift to how quickly they are able to pass through the area.
This would not only contribute to achieving the fast end-to-end cross-London paths that are a priority for freight but would also reduce the time trains would occupy the junction, increasing performance resilience at Gospel Oak, the impact of which would drive improvement right across the North London Line and Gospel Oak and Barking Line.
This map from cartometro shows the track layout at Gospel Oak.
Note.
- The double-track North London Line passing through Platforms 1 and 2 at Gospel Oak station.
- The double-track Gospel Oak and Barking Line passing to the North of the station.
- Platform 3 is a West-facing bay platform for services to Barking.
- There is no Westbound connection to Platform 3.
- All tracks in the map are hace 25 KVAC overhead electrification.
The two double-track railways merge west of the station at Gospel Oak junction.
This Google map shows the same area.
Note.
- Gospel Oak junction is in the North-West corner of the map.
- Platform 1 and 2 of Gospel Oak station are in the South-East corner of the map.
This Google map shows the junction to a larger scale.
There would appear to be space to the North of the junction for expansion.
It might even be possible to squeeze in another line, so that trains can go straight through at a faster speed.
Conclusion
This looks like another junction, that could be easy to improve on an engineering basis.
But whether the locals will accept it quietly could be another matter.
