Extending The Elizabeth Line – Rebuilding Shenfield Station
I have a feeling that Shenfield station will become a bottleneck on the Great Eastern Main Line.
- I feel that both passenger and freight traffic will increase through the station in the next ten years.
- I also feel that there is a possibility that the Elizabeth Line will be extended to Southend/Airport/Victoria and/or Beaulieu.
- Yesterday, I changed between a Southend and a Lizzie Line service, which meant down in one lift and up in another.
- With more and more housing likely to be built in the area, I wouldn’t be surprised to see a lot more parking.
I wouldn’t be surprised to see the station needing to be rebuilt and expanded in the next few years.
Extending The Elizabeth Line – Will There Be A Need For Long Distance Class 345 Train?
I wrote Crossrail To Heathrow, Reading And Southend in August 2017.
This was a section in that post.
The Long Distance Class 345 Train
Adding Oxford and/or Southend to Crossrail services, may need a sub-class of Class 345 train to be created, due to the length of the journey. Toilets would be the obvious addition.
As an example, the safeguarded Reading and Gravesend service would be eighty-three miles.
- A Reading and Paddington service takes fifty-seven minutes for the thirty-six miles.
- At that speed Reading and Gravesend would take two hours and eleven minutes.
- Even Reading and Shenfield will will take only nine minutes less than two hours.
Will all passengers be able to hold on for these lengths of time?
100 mph Capability
Greater Anglia’s Class 720 trains are 100 mph trains, but their sisters on the Elizabeth Line are only 90 mph trains.
So if the trains are to work perhaps to Gravesend, Oxford or Southend would a 100 mph capability be needed?
Conclusion
If the Elizabeth Line is extended, there may be a need for trains to be updated.
Extending The Elizabeth Line – An Extension To Southend Airport
The Wikipedia entry for Crossrail, has a section for an extension to Southend Airport, where this is said.
Stobart Aviation, the company that operates Southend Airport in Essex, has proposed that Crossrail should be extended beyond Shenfield along the Shenfield–Southend line to serve Southend Airport and Southend Victoria. The company has suggested that a direct Heathrow-Southend link could alleviate capacity problems at Heathrow. The extension proposal has been supported by Southend-on-Sea City Council.
I have written about extending Crossrail to Southend before in Council Launches Campaign To Extend Crossrail To Southend-on-Sea.
In that post, I gave these reasons.
- Extra capacity between London and Southend
- A more intensive service to Southend Airport
- A twenty-four hour service to Southend Airport
- Enabling housing
- Taking pressure from Liverpool Street
I came to the conclusion, that extending the Elizabeth Line to Southend could have a lot going for it.
Times Change
But that post was written nearly four years ago and times change and they will change more in the next few years.
The Elizabeth Line Trains Are Shorter Than The Liverpool Street And Southend Victoria Trains
This has also happened and the pair of five-car Class 720 trains, that Greater Anglia use for Southend Victoria services are over thirty metres longer than the Elizabeth Line’s nine-car Class 345 trains.
This would mean that there would be no need for platform lengthening along the route to Southend Victoria.
Zero-Carbon Aircraft Are Under Development
Zero-carbon aircraft like the Heart Aerospace ES-19 could be in service by 2027. These aircraft will probably have a limited range of around 400 km and a charge time of 40 minutes.
- Southend Airport’s position on the East side of London would enable the creation of zero-carbon flights to places like Amsterdam, Brussels, Lille, Paris and Rotterdam.
- A quick estimate indicates that aircraft like the ES-19 could fly from Southend to Amsterdam and recharge in around two hours.
- Intensively scheduled, these electric aircraft could make several round trips per day.
- Would almost silent electric aircraft be able to fly twenty-four hours per day?
These flights could seriously increase the number of passengers to Southend Airport before the end of the decade.
More Housing
I think more housing will be built between Shenfield and Southend, which will increase the need for more services past Shenfield.
The Great Eastern Main Line Will Have Full Digital Signalling
More and more trains will be running on the Great Eastern Main Line and like other main lines in the UK, it will receive full digital signalling, which would probably be applied to the Shenfield and Southend Line.
This would give the extra capacity to Southend Victoria, that running the Elizabeth Line to Southend Airport and Southend Victoria would need.
Possible Services
I think there are two main possible options, but there may be others.
- A long Elizabeth Line extension all the way to Southend Victoria.
- A short Elizabeth Line extension only as far as Southend Airport.
My feelings are as follows.
- The Greater Anglia service should remain as it is with three trains per hour (tph) calling at all stations to Shenfield, Stratford and Liverpool Street.
- Perhaps three or four Elizabeth Line tph would extend to Southend Victoria, calling at all stations.
- All Elizabeth Line trains would call at all stations to and from London, as they do now!
Full digital signalling would handle the extra trains.
Conclusion
I think it will be unlikely that the Elizabeth Line will be extended to Southend in the next few years, but before the end of the decade, I can certainly see limited Elizabeth Line services going all the way to Southend Victoria.
