Crossrail Ltd Outlines Plan To Complete The Elizabeth Line

The title of this post is the same as this statement on the Crossrail web site.

These are a few points from the statement.

The Opening Date Of The Central Section

This is a sentence from the statement.

Crossrail Ltd has identified a six-month delivery window with a midpoint at the end of 2020. Crossrail will be making every effort to deliver the service as early as possible.

Does that meet some date between the 1st October 2020 and 31st March 2021?

And what will open on that date?

There is then this paragraph.

The central section of the Elizabeth line will open between Paddington and Abbey Wood and link the West End, the City of London, Canary Wharf and southeast London with initially 12 trains per hour during the peak.

Twelve trains per hour (tph) gives a capacity of 18,000 passengers per hour, which compares with the 36 tph and 31,500 passengers per hour of the Victoria Line.

Practically, this means that a twelve tph Crossrail could be carrying sixty percent of the number of passengers of the Victoria Line. It’s better than a kick in the teeth!

But then Dear Old Vicky is the Platinum Standard with lots of encrusted diamonds!

Bond Street Station

This is a sentence from the statement.

It is expected that all stations on the route will open except for Bond Street which is delayed because of design and delivery challenges.

The stations are designed so that trains can pass through, so this is not a problem.

Western Branch Services

This is a paragraph from the statement.

TfL Rail services between Paddington and Reading will commence in December 2019 with a frequency of 4 trains per hour in the peak. Testing of the signalling system continues to allow the new class 345 trains to be extended from Hayes & Harlington to Heathrow.

When Crossrail is fully open, the Western Branch frequencies are planned to be as follows.

  • Reading and Abbey Wood – 4 tph in the Peak and 2 tph in the Off Peak
  • Maidenhead and Abbey Wood – 2 tph all day
  • Heathrow Terminal 4 and Abbey Wood – 4 tph all day.
  • Heathrow Terminal 5 and Abbey Wood – 2 tph all day.

Currently, TfL Rail’s services are as follows.

  • Heathrow Terminal 4 and Paddington – 2 tph all day
  • Hayes & Harlington and Paddington – 2 tph all day

It appears that the two Hayes & Harlington services are designed and timed, so they can be extended to Heathrow Terninal 5, with trains leaving Paddington at these times.

  • XX:08 – Heathrow Terminal 4
  • XX:10 – Heathrow Terminal 5
  • XX:23 – Heathrow Terminal 4
  • XX:38 – Heathrow Terminal 4
  • XX:42 – Heathrow Terminal 5
  • XX:53 – Heathrow Terminal 4

Perhaps, if the signalling had worked as intended, we would now be seeing Class 345 trains working as follows.

  • Heathrow Terminal 4 and Paddington – 4 tph all day
  • Heathrow Terminal 5 and Paddington – 2 tph all day

Once the signalling works as needed and signed off in blood, sweat and tears, the difficult part of the job has been done.

The Reading and Maidenhead services could then be added to the mix. Especially, as no problems have been admitted or rumoured with running to these destinations.

These would mean twelve trains per hour in the Peak and ten trains per hour in the Off Peak needing to be handled at the London end of the Western Branch of Crossrail.

Paddington Station Or Central Tunnel?

The twelve tph in the Peak and ten in the Off Peak is an interesting frequency.

In If Crossrail Opens To Reading In December 2019, How Will It Terminate In Paddington?, I describe how Heathrow and Reading services at a frequency of twelve tph,  could run into Platforms 12 and 14 at Paddington.

This was my conclusion.

Platform 12 and 14 at Paddington could be converted into a two-platform Crossrail station handling seven-car Class 345 trains, at a frequency of twelve tph, with its own gate line.

I’ll ralso epeat this paragraph from the statement.

The central section of the Elizabeth line will open between Paddington and Abbey Wood and link the West End, the City of London, Canary Wharf and southeast London with initially 12 trains per hour during the peak.

Twelve tph in the Peak is the maximum frequency of the Western Branch into London.

Crossrail have designed a system, where trains can initially terminate in either Paddington or Abbey Wood stations.

Tp give themselves all options and get the Western Branch running, Crossrail would need to complete and certify the following.

  1. Get the signalling working to Heathrow.
  2. Make sure twelve tph could terminate in Paddington.
  3. Make sure twelve tph could run  through the tunnel between Royal Oak and Abbey Wood.

This would mean it would be possible to run twelve tph from Heathrow, Maidenhead and Reading in the West to either Paddington or Abbey Wood in London.

As twelve tph is only one train every five minutes, this surely could be run safely, once the three tasks above are complete and signed off.

Running A Split Service

This is said in the statement.

When the Elizabeth line opens the railway will operate as follows:

  • Paddington (Elizabeth line station) to Abbey Wood via Central London
  • Liverpool Street (main line station) to Shenfield
  • Paddington (main line station) to Heathrow and Reading

At a first look it appears to be a sensible plan.

  • All three services are independent of each other
  • Liverpool Street and Shenfield is working well and will carry on regardless as long as needed at six tph.
  • The Abbey Wood and Heathrow/Reading services can be run as two independent rail  services.

The following will also get a thorough testing.

  • Paddington (Elizabeth Line station)
  • The interchange tunnel between the Bakerloo Line and Paddington (Elizabeth Line station)
  • The important turnback facility at Royal Oak for trains turning in the Paddington (Elizabeth Line station)

The only problem, is that passengers will have to change trains at Paddington.

Running A Limited Preview Service In The Central Tunnel

Would it be possible to run a preview service in the Central Tunnel, after the following are tested and certified?

  • The turnback facility at Royal Oak
  • Paddington (Elizabeth Line station)
  • The intermediate stations.
  • The operation of trains in the tunnel at twelve tph.
  • Abbey Wood station.
  • The turnback facility at Abbey Wood.

A frequency of four or six tph may give the station systems a thorough testing.

Rolling Out The Full Service

This is a paragraph from the statement.

Once the central section opens, full services across the Elizabeth line from Reading and Heathrow in the west to Abbey Wood and Shenfield in the east, will commence as soon as possible.

I would assume stations and extra services will be added as soon as testing is complete and drivers and station staff are fully-trained.

Conclusion

The plan is good, as it allows these and other systems to be tested independently.

  • The signalling into Heathrow.
  • Twelve tph trains to and from Heathrow, Maidenhead and Reading.
  • Operation of the platforms in Paddington (main line station)
  • Operation of the turnback facility at Royal Oak
  • Operation of the platforms in Paddington (Elizabeth line station)
  • Handling of twelve tph and the signalling in the Central Tunnel.
  • Operation of the turnback facility at Abbey Wood.

I wouldn’t be surprised, that if all goes well, we may be seeing a very limited Crossrail service earlier than anybody currently thinks.

It would also appear to get the Western and Shenfield branches working independently to provide much needed, more frequent and quality services,.

These will then be joined by services in the Central Tunnel, which initially will be run independently.

As I said earlier a twelve tph Crossrail between Paddington and Abbey Wood through the Central Tunnel, would carry sixty percent of the passengers of the Victoria Line!
