Extra Services To Southport On Merseyrail’s Northern Line

Local interests have ambitions to connect Ormskirk and Southport stations, as is detailed in Wikipedia under Future Developments in the Wikipedia entry for Ormskirk station.

There have been calls from local authorities and the local rail user group to reopen both curves at Burscough to allow the reinstatement of through trains from here to Southport, as well as to reinstate through services between Preston & Liverpool via Ormskirk and to rebuild & reopen the Skelmersdale branch.[7] Merseytravel’s 2014 ‘Liverpool City Region Long Term Rail Strategy’ does not back plans for an Ormskirk to Skelmersdale route (instead proposing that the link be provided from the Kirkby to Wigan Wallgate line), though it does suggest that a new bi-level interchange at Burscough Bridge could be built to provide improved interchange facilities between the Ormskirk branch and the Wigan to Southport line in addition to reopening the curves and extending electrification through to Preston & Southport.

, To connect the two stations would mean doing at least the following.

  • Reinstate the South Burscough Curve as a single track
  • The South Burscough Curve would have bi-directional signalling and third rail electrification.
  • Remodel Ormskirk station.

This picture shows what remains of the second platform at Ormskirk station.

The second platform could probably be reinstated reasonably easily, but I wonder if a clever station designer and train scheduler could organise Liverpool, Preston and Southport services around a single long platform?

The current layout could be actually considered to be two platforms, as one end serves Liverpool trains and other Preston trains.

So in this explanation, I’ll refer to them as the Liverpool Platform and the Preston Platform.

  • The Liverpool platform would be long enough to take two new Stadler trains.
  • The Preston platform would be long enough for the longest train likely to work an Ormskirk to Preston service.
  • An electrified passing loop starting from between the two platforms and extending towards Burcough Junction station would be installed.

Consider.

  • Trains arriving and returning to Liverpool would operate as they do now using the Liverpool platform.
  • Trains arriving and returning to Preston would operate as they do now using the Preston platform, but stop within the passing loop.
  • Passengers changing between Liverpool and Preston services would change trains as they do now, by walking along the platform.
  • Liverpool to Southport and Liverpool to Preston services would use the Liverpool platform and would either go through the Preston platform or use the passing loop as appropriate.

Two parallel platform stations are so nineteenth century!

These modifications between Ormskirk and Southport  would improve train services in the following ways.

  • Create more capacity between Liverpool and Southport.
  • Allow travellers to go between Southport and the Ormskirk Branch of the Northern Line , without going via Sandhills station.
  • Allow access to Manchester services at Burscough Bridge station
  • Add direct Liverpool services to those to Manchester and Southport to all the new housing that seems to be under construction around the Southport to Manchester Line.
  • Enable the construction of one or more new stations, like Kew Gardens in Southport, which is close to the hospital.

You can certainly understand why Merseyrail appears to be keen.

There are lots of ways to organise services.

I suspect one of the most efficient ways will be to run the trains in a loop going to and starting from Hunts Croos and going to Liverpool Central via Liverpool Central, Southport, Burscough Bridge, Burscough Junction and Ormskirk. Four trains per hour (tph) would go in one direction and four tph in the other.

Timing with the current trains are as follows.

  • Hunts Cross to Southport – 64 minutes
  • Southport to Burscough Bridge – 22 minutes
  • Burscough Bridge to Ormskirk – 9 minutes – estimated
  • Ormskirk to Liverpool Central – 34 minutes
  • Kirkby to Liverpool Central – 18 minutes.

These timings are not the easiest to put together to make a four tph schedule.

As an example, if you want a current Class 508 train to go from Hunts Cross to Southport and back again, it will take 128 minutes plus whatever it takes to turn the train at each end. Allowing eleven minutes at each end gives a time of two and a half hours, which means ten trains are needed for a full four tph.

Ormskirk to Liverpool central will also need trains. If they could do Liverpool Central to Ormskirk and back in under an hour, that would need four tph..

The new Stadler trains have been designed to do the journey nine minutes quicker, which means that if the turnrounds are a bit quicker, it could be possible to do the round trip in two hours, which would mean only eight trains would be needed for a full four tph.

Ormskirk to Liverpool central will also need trains. If they could do Liverpool Central to Ormskirk and back in under an hour, that would need four tph..

If you look at the full loop with the current trains, this takes 258 minutes plus perhaps 30 minutes for the two reverses at Southport and the one at Liverpool Central. So we get a time of probably three hours and a requirement of 12 trains to run 4 tph to both Ormskirk and Southport and provide a four tph service between the two current termini.

As the current services need ten trains for Hunts Cross-Southport and four for Liverpool Central-Ormskirk, the loop saves two trains.

With the new Stadler trains, I suspect they could do the loop diagram in under two hours, which would mean just eight trains for a full four tph.

Thus, extra services can be provided between Ormskirk and Southport with a requirement of four less trains than running the lines individually.

Services to Southport and Ormskirk from Liverpool would be as follows.

  • Southport to Hunts Cross via Formby – 4 tph
  • Southport to Liverpool Central via Ormskirk – 4 tph

But the big difference is most stations on the Northern Line are served by four tph from Hunts Cross and Southport and all the other stations need a single change and a wait of a few minutes.

To operate the loop service, it would need Ormskirk to Southport to be fully electrified.

Southport To Manchester

You then have the situation if a Class 319 Flex train were to work Southport to Manchester, that it would work as follows.

  • Southport to Burscough Bridge – using third-rail electrification when installed.
  • Burscough Bridge to Bolton – using diesel power.
  • Bolton to Manchester – using overhead electrification.

Southport would become an all electric station.

To get a full electric service to Manchester, it would only be necessary to electrify between Manchester and Burscough Bridge, where the chsngeover would take place.

I have followed this line in my helicopter and there are only three small bridges and a level crossing between Burscough Bridge and Wigan Wallgate stations.

So I suspect electrifying from Wigan to Burscough Bridge could be an easier electrification than most.

Conclusions

I have come to the following main conclusion.

Combining Southport and Ormskirk services in a loop via a reinstated South Burscough Curve, means the following.

  • Southport gets eight trains per hour (tph) to and from Liverpool.
  • Ormskirk gets four tph to and from Liverpool.
  • All stations on the Northern Line get four direct or single-change tph from Hunts Cross, Southport and Liverpool Central.
  • Ormskirk to Southport and all intermediate stations get 4 tph in both directions.
  • The service can be run by less trains than needed for independent operation to Southport and Otmskirk.

Southport to Ormskirk needs third-rail electrification.

There were a some subsidiary conclusions.

  • Ormskirk station can be based on a single platform with a passing loop, which could allow Liverpool-Preston services.
  • Ormskirk station could still run the current Ormskirk to Preston service.
  • The third-rail electrification between Southport and Burscough Bridge stations could be used by Class 319 Flex trains working services between Southport and Manchester.
  • Southport could become an all electric station.

I suspect that others could do much better.
