Is Caledonian Road And Barnsbury An Ideal Four-Track Station?

This Google Map shows Caledonian Road And Barnsbury station.

Note the island platform, with two tracks on either side.

These four pictures show each pair of tracks in both directions.

And these pictures show general views of the station.

I don’t know the layout of every station, but Caledonian Road And Barnsbury seems to be unusual.

  • There is a spacious island platform in the middle of the four tracks.
  • On either side of the island platform, there are the two lines for local passenger trains.
  • Outside of the two local passenger lines, there are two lines for freight trains.
  • Access to the island platform is via a simple half-bridge with only two lifts.
  • Everybody enters the station from one side.

Does this layout have advantages?

Ease Of Construction

I think that this station was designed, so that it was quick and easy to build.

Once the tracks are aligned correctly, it shouldn’t be too complicated to build.

The bridge only has to span two tracks, so that must be half the work of crossing four tracks.

Passenger Safety

I have used real time trains to check the platform of freight trains passing through Caledonian Road And Barnsbury station.

It seems that only rarely do trains use the tracks in the two platforms.

This must surely be safer, when compared with the standard arrangement.

These pictures were taken at Highbury & Islington station.

The wide platform, also allows passengers to keep well out of the way of any trains that do pass through.

Would The Layout Work With High Speed Trains?

I don’t see why not!

The space between the outside lines and the platform, almost acts like a moat in a zoo, that keeps visitors away from dangerous animals.

Costs

It was probably not an expensive station to build.

Conclusion

Why are other four-track stations not built like this?

The main reason is probably, that most four-track main lines were laid out decades or even centuries ago and their builders used their own layouts.

Will Camden Road Station Get A Third Platform?

 

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 recommendations of the report is to build a third platform at Camden Road station. It says this about the third platform.

Reinstatement of a third track and platform on the northern side of Camden Road station, utilising part of
the former 4-track formation through the station.

Camden Road station used to have four platforms, but now it just have two.

This Google Map shows the station as it is today.

Note.

  1. Platform 1 is on the South side of the tracks with the London Overground roundel conveniently shown on the roof.
  2. Platform 2 is on the North side of the tracks.
  3. Regular users of the station can probably pick out the lift at the Eastern end of Platform 2.
  4. There is a bridge to the East of the station which takes the tracks over the junction of Royal College Street and Camden Road.

To the North of this bridge, two further bridges can be seen, that used to take the former third and fourth tracks over the roads and into two additional platforms to the North of the current two.

This map from cartometro.com shows the track layout through Camden Road station.

Note.

  1. The tracks shown in orange are the route of the North London Line of the London Overground.
  2. The two orange platforms labelled 1 and 2 at Camden Road station.
  3. The two former lines passing behind Platform 2, used to rejoin the North London Line to the West of the station.

These pictures were taken on the current Platform 2.

And these are some pictures of the bridge, what is behind the fence and other bridges.

Note.

  1. Most of the pictures of Platform 2, were taken from Platform 1.
  2. Behind the fence on Platform 2, there appears to be a substantial urban forest.
  3. Renewing the bridges and updating the railway arches could improve the area significantly.
  4. Camden Road station is a Grade II Listed building.

I don’t think, that any of the construction would be too challenging.

How Would The Third Platform Be Used?

This is said in the Network Rail document about the third platform at Camden Road station.

This proposal would reinstate a third track and platform on the northern side of Camden Road station, utilising part of the former 4-track formation through the station.

The additional capacity provided would facilitate much greater flexibility in pathing options for trains on this busy central section of the NLL, opening up new options for future service provision and bolstering performance resilience.

Reinstatement of a third platform would enable platform 2 to be used as a central turnback, with platform 3 becoming the eastbound line for through London Overground services and the majority of freight.

Transport for London modelling suggests that the eastern end of the NLL, from Canonbury to Stratford, will see some of the strongest long-term demand growth on the Overground network.

A turnback platform will allow this to be addressed with peak capacity boosting services between Stratford and Camden Road and there would also be the option to operate these through the off-peak, which could offer a means of providing additional passenger capacity where it is most needed.

The availability of an additional platform would also aid performance recovery during perturbation on
the orbital routes.

That all looks fairly sensible and wouldn’t require much work to the current station.

Note.

  1. Platform 2 is currently a fully-accessible platform with a lift and will become a spacious fully-accessible island platform with two faces 2 and 3, both serving London Overground services going East.
  2. There must surely be space on the island platform to build a substantial shelter, where passengers can sit, when long freight trains are passing through.
  3. There could even be space for a coffee kiosk.

The former Platform 3 appeared to be a Westbound platform, but the proposed new one appears to be an Eastbound one.

The Track Layout Immediately To The East Of Camden Road Station

These are my thoughts on the track layout to the East of Camden Road station.

This map from cartometro.com shows the track layout between Camden Road and Highbury & Islington stations.

Much of the route through Caledonian Road and Barnsbury station is four tracks. These tracks are named from North to South as follows.

  • Down North London Reversible
  • Down North London
  • Up North London Reversible
  • Up North London

Note.

  1. Eastbound London Overground services use the Down North London track.
  2. Eastbound freight services use the Down North London Reversible track.
  3. Eastbound freight services are sometimes held by signallers on the Down North London Reversible track.
  4. Westbound London Overground services use the Up North London Reversible track, before crossing over to the Up North London track at Camden Road East Junction.
  5. London Overground services only use the central island platform at Caledonian Road and Barnsbury station.
  6. Westbound freight services use both of the Up North London tracks.
  7. The London Borough of Camden have stated that they would like to see the reopening of Maiden Lane station.

These pictures show the former trackbed between the former Maiden Lane station and Camden Road station.

Looking at these pictures, I can deduce the following.

  • There is very little constructuction of the former trackbed.
  • There would be some signalling equipment to move.
  • Some of the steel bridges would have to be replaced.

I feel,  that a single track could definitely be created between the new Platform 3 at Camden Road station to connect with  both Down North London tracks before the site of the former Maiden Line station.

It may even be possible to squeeze in two tracks.

A new track or tracks would enable the following.

  • Eastbound London Overground services to go from Platform 3 at Camden Road station to Platform 3 at Caledonian Road and Barnsbury station.
  • Eastbound freight services to go from Platform 3 at Camden Road station to either the Down North London Reversible or the Down North London tracks through Caledonian Road and Barnsbury station.

Note.

  1. Westbound services going through Camden Road station would be unaffected.
  2. Westbound London Overground services terminating in Platform 2 at Camden Road station would cross over to the current Up North London Reversible at the current Camden Road Central junction.
  3. Eastbound London Overground services starting in Platform 2 at Camden Road station would cross over to the new track or tracks to proceed to the East.

These are my answers to a few questions.

Will There Be One Or Two Extra Tracks?

Consider.

  • It could probably be organised that the extra track or tracks start perhaps fifty metres or so to the East of Camden Road station.
  • The distance between this point and Westbourne Road Junction is around a mile.
  • Network Rail allows freight trains up to a length of 775 metres.

I am drawn to the conclusion, that if two tracks were to be built, then signallers would be able to hold the longest freight trains on the extended Down North London Reversible track, without interrupting London Overground passenger services.

How Will The Extra Tracks Affect The Camden Highline?

If two new tracks are built, I would expect that it will be impossible to build the Camden Highline.

But if only one is built, I suspect that a narrower Camden Highline might be able to be squeezed in.

Could Provision Be Made So A New Maiden Lane Station Could Be Built?

This map from cartometro.com shows the track layout around the former Maiden Lane station.

Consider.

  • Eastbound London Overground services use the Down North London track and call in Platform 3 at Caledonian Road and Barnsbury station.
  • Westbound London Overground services use the Up North London Reversible track and call in Platform 2 at Caledonian Road and Barnsbury station.
  • To connect Platform 3 at Camden Road station to the Down North London Reversible and Down North London tracks, I suspect that Camden Road East junction will have to be remodelled.

I wonder if by the application of Network Rail’s latest track layout software, space could found for an island platform between the Up North London Reversible and Down North London tracks.

In Is Caledonian Road And Barnsbury An Ideal Four-Track Station?, I discuss the design of Caledonian Road and Barnsbury station,

I think it is a distinct possibility, that provision could be made for a future Maiden Lane station.

Will There Be Changes At Camden Road West Junction?

This map from cartometro.com shows the track layout to the West of Camden Road station.

Note.

  1. Platforms 1 and 2 of Camden Road station at the Eastern end of the map.
  2. Camden Road West junction to the West of the platforms.
  3. The dotted lines of old tracks leading to the former Platform 3 and 4 at Camden Road station.

Two double tracks lead away to the West from Camden Road West junction.

  • The orange tracks are the North London Line to Willesden Junction and Acton.
  • The black and orange tracks are an extension of the Watford DC Line, that links Camden Road station to the West Coast Main Line via Primrose Hill station.

Will both pairs of tracks be connected to the North London Line at Camden Road West junction, as they are now?

  • Currently, a few freight trains per day, use the Primrose Hill route.
  • There have been plans in the past, for the London Overground to use this route.
  • They have also been known to run a Rail Replacement Train between Willesden Junction and Camden Road stations during engineering works, as I wrote about in The Future Of The Watford DC Line.

So I suspect Network Rail will design a comprehensive junction, that is all things to all operators and trains.

Through Running Between The East London Line and Willesden Junction Station

This was originally talked about in the original plans for the London Overground.

If you travel on the Overground to Barking, Blackhorse Road, Canada Water, Highbury & Islington, West Brompton, Hampstead, Whitechapel or Willesden Junction in the Peak, the interchanges are very busy, as passengers are transferring to the Underground.

Was this why through running was originally proposed between the East and North London Lines at Highbury & Islington station, as it would allow direct connection to extra Underground lines?

But one of the aims of the Overground was to enable journeys around London without going via Central London.

Platform 3 at Camden Road station, seems to increase the capacity on the North London Line, so perhaps this upgrade would give extra paths to allow some services to terminate to the West of Highbury & Islington.

This map from cartometro.com shows the track layout to the West of Highbury & Islington station.

I’m sure if Network Rail’s engineers can sort out King’s Cross, then they can come up with a track and signalling system that can handle this,

Could Platform 2 At Camden Road Be Used As An Alternative Terminus For Watford DC Line Services?

Euston station is being rebuilt and Network Rail might like to kick Watford DC Line services out of the station either temporarily or even permanently.

There are two routes that the Watford DC Line could take to get between Harlesden and Camden Road stations.

  1. They can use the route, I took one Sunday, when the London Overground was running a Rail Replacement Train, via Willesden Junction Low Level, Kensal Green, Queens Park, Kilburn High Road and South Hampstead.
  2. They might also be able to join the North London Line an improved Kensal Green junction.

The first route works and the second may need some extra work at Harlesden junction.

I estimate that Platform 2 at Camden Road station is presently as long as 120 metres.

I also estimate that it could be lengthened at both ends, during the building of a new platform 3 alongside.

Could a platform be built long enough to be able to handle two trains simultaneously?

A 200 metre long platform would probably suffice!

I think the concept has possibilities.

  • Willesden Junction station has connections to the Bakerloo Line.
  • West Hampstead station has connections to Thameslink and the Jubilee and further connections could be developed,
  • Camden Road station could be connected to Camden Town station, which is on both branches of the Northern Line.
  • A reopened Primrose Hill station could be connected to Chalk Farm station on the Northern Line.
  • The Northern Line connects to Crossrail at Moorgate and Tottenham Court Road stations.

I suspect, if Camden Town station were to be expanded and rebuilt, that the connection between the two Camden stations would be more likely.

Either route could be taken between Willesden Junction and Camden Road stations.

But I feel, it might be less costly to take the North London Line route, especially, as this connects to West Hampstead station.

Could The Track Layout Be Further Simplified?

I’m no track expert, but it strikes me that a four-track layout could be built between just East of Camden Road station and Westbourne Road junction. From North to South these tracks would be.

  • Eastbound Freight line – Connecting at the Western end to Platform 3 at Camden Road station and following the existing Down North London Reversible track to Westbourne Road junction.
  • Eastbound Overground line – Connecting at the Western end to Platforms 2 and 3 at Camden Road station and following the existing Down North London track through Caledonian Road and Barnsbury station to Westbourne Road junction.
  • Westbound Overground line – Connecting at the Western end to Platforms 1 and 2 at Camden Road station and following the existing Up North London Reversible track through Caledonian Road and Barnsbury station to Westbourne Road junction.
  • Westbound Freight line – Connecting at the Western end to Platform 1 at Camden Road station and following the existing Up North London track to Westbourne Road junction.

Note.

  1. Both freight lines would be long enough for signallers to hold freight trains, so that other services could overtake.
  2. East of Caledonian Road and Barnsbury station, Overground and freight service would share the two tracks, as they do now!
  3. West of Camden Road station, Overground and freight service would share the two tracks, as they do now!

It strikes me that by good design, the capacity and speed through this section of the busy North London Line can be increased.
