Are Londoners The Tunnel Kings?
I was born in 1947 and it was in the early 1960s, that I started to develop an interest in engineering, which eventually led me to study Electrical Engineering and Electronics at Liverpool University.
Like most Londoners, I was a frequent user of the Underground and for six or seven years, I took the Piccadilly Line many days between Oakwood and Southgate to go to Minchenden Grammar School. Often, after school, I would go on to my father’s print works near Word Green tube station.
But not memories of London’s tunnels were so memorable at that time. One day, we were driving to see my Uncle Bert in Broadstairs and we were held in the Blackwall Tunnel for an hour or so because of an accident.
Perhaps, this is why I can remember a black-and-white video of digging the Western Tunnel of the Dartford Crossing so vividly. But as Raymond Baxter probably explained to BBC viewers at the time, it dug using a Greathead shield under pressure to keep the water out. It was probably the last tunnel dug under the Thames using methods, that would have been familiar to Victorian engineers.
This British Pathe video shows some of the construction of the Western tunnel.
This paragraph from the Wikipedia entry for the Eastern Tunnel describes its construction.
Construction was approved in April 1971, with an initial expected opening date in 1976. Work was delayed due to a lack of funds, which was resolved by EEC funding granted in 1974. The second tunnel opened in May 1980, allowing each tunnel to handle one direction of traffic, by which time the joint capacity of the two tunnels had increased to 65,000 vehicles per day. Connection of the crossing to the M25 was completed on the northerly Essex side in September 1982 (Junction 31), and to the southerly Kent side in September 1986 (Junction 1a)
The tunnels may be inadequate in terms of capacity, but they have certainly done a reliable job for sixty and forty-three years respectively.
There are other tunnels under the Thames, that have been built in my lifetime.
- Thames Cable Tunnel – 1970 – National Grid’s 400 kV cable.
- High Speed One – 2007
- Dartford Tunnel (East) – 1980
- Dartford Tunnel (West) – 1963
- Dartford Cable Tunnel – 2004
- Docklands Light Railway Tunnel – 2009
- Elizabeth Line Tunnel – 2014
- Millennium Dome Cable Tunnel – 1999
- Jubilee Line Tunnels – 1999 – Planned by Artemis
- Blackwall Runnel (East) – 1967
- Isle of Dogs Jubilee Line Tunnels – 1999 – Planned by Artemis
- Docklands Light Railway Tunnel – 1999 – Planned by Artemis

There are also these tunnels, which don’t go under the Thames
Bank Station Expansion And New Southbound Northern Line Tunnel – 2022
- Elstree to St. John’s Wood Cable Tunnel – 2005
- Heathrow Rail Tunnels – 1998
- Lee Tunnel – 2016
- Limehouse Link Tunnel – 1993
- Lower Lea Valley Cable Tunnels – 2008
- Northern Line Extension To Battersea – 2021
- Piccadilly Line Extension To Heathrow – 1975-2008
- Thames Tideway Tunnel – Estimated completion in 2025 – Tunnelling ended in 2022.
- Thames Water Ring Main – 2010
Note.
- The date is the opening date.
- I am pleased to see that at least some projects were planned, with the software, I wrote in a Suffolk attic.
In my lifetime, at least 27 substantial tunnels have been completed, a very large proportion of which have been on time and on budget, with the possible exception of the Heathrow Rail Tunnels, which collapsed.
So Why Has London Got A Good Record On Tunnelling?
In Millicent And Ursula Prepare To Go Tunnelling, I describe my visit to the Tideway Open Day today to see the tunnel boring machines; Millicent and Ursula before they went tunnelling.
On that Sunday morning, I also chatted with the engineers and tunnelers.
- All had worked on at least one of London’s previous tunnels.
- One had worked on the Second Dartford Tunnel, the Channel Tunnel and Crossrail.
- A couple said, that after the Tideway finished, they would be off to High Speed Two.
Is London’s good record on delivering tunnels safely and on time and on budget, a case of lots of experience and practice makes perfect?
If it is, we should definitely think hard about how we handle large projects.
Wind Farms
Many have been constructed this way.
- The grid substation and connection to the grid is built.
- The foundations of the turbines are installed.
- The turbines are erected.
- All the turbines are commissioned.
This sequence or something like it can be applied to onshore and offshore wind farms.
- Most jobs are repeated many times by specialist teams using purpose-built cranes, ships and other equipment.
- Bigger wind farms, just need more repeated operations.
- All operations are generally in a small geographical area.
- I suspect specialist software has been built to project manage, the building of wind farms. If it hasn’t, I have my ideas.
Project management should be relatively easy.
Improvements To Edmonton Green Station
This post on IanVisits is entitled Enfield Council Outlines Possible Rail Station Upgrades.
By reading Enfield Council documents, Ian has found possible station improvements that might happen.
Ian says this about Edmonton Green station.
A proposed redevelopment of the shopping centre could add upwards of 1,000 new homes in time, and fund improvements to both the railway station and the bus station.
I took these pictures of the station.
Note.
- The station has lifts to both platforms.
- The station has some excellent period features.
- I have indicated a couple of possible development sites.
- The station does not appear to be listed.
A good architect and some good craftsmen could improve this station substantially.
Wrightbus Nears Completion Of First Hydrogen Buses For Continental Europe
The title of this post, is the same as that of this article on Sustainable Bus.
This is the first paragraph.
UK bus manufacturer Wrightbus announced through a Linkedin post it is in the final stages of completing its first batch of left-hand-drive single-deck hydrogen buses, known as the Kite Hydroliner, destined for Germany and adhering to full VDV compliance. In May 2022 Wrightbus secured an order from RVK Cologne for 20 fixed and 40 optional orders.
This paragraph is also significant.
The buses come equipped with stated range of 1,030 kilometers, a fully flat saloon floor, rapid refueling in under 8 minutes, and are crafted “using key components from tier 1 global suppliers”.
A 1030 kilometre (640 miles) range is enough to go between London and Carlisle and back.
The Long Platforms At Liverpool Street Station
I was on Liverpool Street station today and I took these pictures.
It got me thinking.
- I was standing On Platform 1 and on Platform 2 was a pair of five-car Class 720 trains coupled together.
- The pair of five-car Class 720 trains would be 244 metres long, which mean that the platforms could handle nine-car Class 800 or Class 345 trains.
- There would appear to be plenty of platform space in Liverpool Street station.
- In Azuma Test Train Takes To The Tracks As LNER Trials Possible New Route, I talked about how LNER were checking an Azuma train could use the route to Cleethorpes.
- In London North Eastern Railway Runs Trial Train To Liverpool Street, I talked about how LNER had ran a train into Liverpool Street.
The general consensus seems to be, that points 3 and 4, are about several things.
Adding Grimsby and Cleethorpes to LNER’s list of destinations.
Possibly adding Spalding, Sleaford, Market Rasen and Barnetby to LNER’s list of destinations.
Providing a faster service between London and Grimsby/Cleethorpes.
Providing a diversion route because of engineering or blockades on the East Coast Main Line.
Nearly twenty years ago, I used to play real tennis, with a guy, who was on a committee, that planned the future of the Cambridge region.
- One of the things he said was that Cambridge was full and there is not enough lab space, factories and housing.
- He felt that Peterborough would make an excellent satellite for Cambridge.
- However, transport links and especially the trains are not the best between Cambridge and Peterborough.
- I wonder, if Cambridge’s overcrowding is spreading the Cambridge Effect into Lincolnshire and the number of rail passengers between Lincoln and Cambridge is growing.
So have LNER taken the bull by the horns and are planning to run a London Liverpool Street and Cleethorpes service via Cambridge?
- It might perhaps run at least six trains per day (tpd) in both directions.
- Stops could include Stratford, Cambridge South, Cambridge, Cambridge North, Ely, March, Peterborough, Spalding, Sleaford, Lincoln, Market Rasen, Barnetby and Grimsby Town.
- Trains could be a five-car Class 800 train.
- The route is fully-electrified between London and Ely.
Note.
- The London King’s Cross and Lincoln service could be discontinued.
- Connection between Cambridge and Lincolnshire is much improved.
- The developing energy powerhouse in North-East Lincolnshire gets a connection to Cambridge and London.
- There could be same-platform interchange at Peterborough for passengers between Cambridge and the North.
- By going via Cambridge, one less train needs to use the bottleneck over the Digswell viaduct.
LNER are trying to get the most out of the new December 2024 East Coast Main Line timetable and I do wonder if a London Liverpool Street and Cleethorpes servce is part of that exercise.
That Was Close!
I took this picture in Liverpool Street station on the Elizabeth Line.
Note.
- The timings of the first two trains.
- The Shenfield train did arrive before the one for Abbey Wood.
How did it manage that? It looks like a another Fujitsu moment in the display to me!
A Black Cab With Cushions
I must have used thousands of black taxis in my life.
But last week, was the first one with cushions.
Even at seventy-six, I still get new experiences.
The Best Plane That Looks Like An Egg
The title of this post is the same as that of this article on interesting Engineering.
This is the sub-heading.
Celera 500L: Redefining aviation with its unique egg-shaped design, unparalleled fuel efficiency, and affordability.
These are the first two paragraphs.
In the world of aviation, where innovation meets the boundless sky, a groundbreaking aircraft is poised to redefine the future of air travel. Meet the Celera 500L, the brainchild of the Otto Aviation Group, an aircraft that not only boasts a distinctive egg-shaped design but also promises to transform the way we think about flying. Set to enter production in 2025, the Celera 500L is a testament to cutting-edge technology and forward-thinking design, promising to make air travel more cost-effective and eco-friendly than ever before.
One cannot help but be captivated by the Celera 500L’s futuristic aesthetics. Its unmistakable egg-shaped design is a departure from the traditional aircraft we’ve grown accustomed to seeing in the skies. However, this unique shape is not just for show; it’s the result of meticulous engineering aimed at reducing drag and maximizing efficiency.
I suggest you read the article and look at Interesting Engineering’s video.
After that have a good look at Otto Aviation’s web site.
Brief details of the business aircraft version are scattered through the pages.
- Passengers – 6
- Range – 5,000 miles
- Fuel-consumption – 33 miles per gallon.
- Power – Single pusher diesel engine.
The Otto Aviation web site, explains how it is done using laminar flow and advanced aerodynamics.
There is also this page on the ZeroAvia web site, which is entitled ZeroAvia & Otto Aviation Partner to Deliver First New Airframe Design with Hydrogen-Electric Engine Option.
Is a new world of aviation emerging?
Extending The Elizabeth Line – Could Open Access Services Use The Elizabeth Line?
In the February 2024 Edition of Modern Railways, there is an article which is entitled First Bid For Sheffield To King’s Cross Paths.
The article is mainly about FirstGroup’s proposal for a new Sheffield and London service, running under the Hull Trains brand.
But, this is the last paragraph.
Modern Railways understands First is working on a number of proposals for additional open access services, and this is an early statement of intent. Other existing open access proposals include Grand Union Trains’ plans for London to Stirling and Cardiff to Edinburgh services, along with an already approved London to Carmarthen service, and the recently submitted Wrexham, Shropshire and Midland Railway application for a London to Wrexham service. It is understood other organisations, including MTR and Virgin, are also working up plans for new open access services.
The respected Modern Railways magazine seem to think, that we’ll be seeing more open access services on UK railways.
These are my thoughts.
A Simple Example – London Crosslink
In Extending The Elizabeth Line – London Crosslink, I said this.
In the Wikipedia entry for the London Crosslink, this is the introduction.
London Crosslink was a passenger train service operated by Anglia Railways between Norwich and Basingstoke, using the North London Line to bypass central London. Class 170 Turbostar diesel multiple units were used, and the service operated between 22 May 2000 and 28 September 2002, supported by funding from the Strategic Rail Authority through its Rail Passenger Partnership fund.
As it was discontinued and it doesn’t seem to be sadly missed, I’m not advocating its reinstatement, but just looking how it might be run after the full opening of the Elizabeth Line.
But surely, there were good reasons, why the service was run in the first place and there might be a need in the future.
These are some characteristics of the service.
- There were about half-a-dozen services in both directions every day.
- At its full length it ran between Norwich and Basingstoke.
- Stops included Diss, Stowmarket, Ipswich, Colchester, Witham, Chelmsford, Ingatestone, Romford, Stratford, Highbury & Islington, Camden Road, West Hampstead, Brentford, Feltham, Staines, Woking and Farnborough (Main).
- Each service seemed to have a different stopping pattern.
- The timetable wasn’t very regular.
- The route wasn’t fully electrified.
It appears that it may have been a difficult service to timetable.
I lived North of Ipswich for some years.
I never used the London CrossLink service, as I had moved away before the service started in 2000.
- I would have found the change to the Central Line at Stratford station useful.
- I would have found the change to the Victoria Line at Highbury & Islington station useful.
- I would have found the change to Thameslink at West Hampstead station useful.
- Basingstoke would have given access to Greater South-West England.
- I could have got a bus to Heathrow from Feltham.
But getting to Marylebone, Paddington and Waterloo would have still been tedious.
Could a replacement for the London CrossLink be routed via the Elizabeth Line?
- The service would use the Elizabeth Line between Stratford and Reading.
- The service would use the Reading and Basingstoke Line between Reading and Basingstoke.
The route has some advantages over the original route.
- Except for the 13.6 miles between Southcote Junction and Basingstoke, the route is fully-electrified.
- Whitechapel will give access to London Overground services.
- Farringdon will give access to Thameslink services.
- There will be a lot of connections at Tottenham Court Road and Bond Street.
- Paddington and Reading will give access to Heathrow, Oxford and West of England services.
- Basingstoke will give access to Greater South-West England.
It is certainly an as-useful route as the original, if not more so.
The Trains
In Extending The Elizabeth Line – Will There Be A Need For Long Distance Class 345 Train?, I set out how a standard Class 345 train could be updated with faster running and a more appropriate interior.
As the Elizabeth Line is likely to need some more trains if High Speed Two is delayed, perhaps some extra trains should be ordered fairly soon.
The Routes
Consider.
- A terminal station would probably need to be electrified to the Elizabeth Line route.
- It would need the infrastructure to turn the trains.
These stations could probably be used as terminal stations.
- Basingstoke
- Bristol
- Cardiff
- Colchester
- Faversham
- Hoo – See Extending The Elizabeth Line – A Branch To The Isle Of Grain.
- Ipswich
- Northfleet – For European services at Ebbsfleet International.
- Norwich
- Oxford
- Rochester
- Southampton
- Southend Victoria
There will certainly be others.
Why Use Open Access?
Suppose an operator wants to run a service between Bristol Parkway and Northfleet to give the West Country access to European services.
- The operator takes all the risk and Network Rail get track access charges.
- Do Transport for London get track access charges for the Elizabeth Line tunnels?
- If they get their predictions and sums wrong, they lose the money.
But if they get it right, they probably sell it to an infrastructure company at a profit.
Conclusion
I think open access operation might work through the Elizabeth Line Tunnels.
Project To Improve Mobile Connectivity On East Coast Main Lone Reaches Key Milestone
The title of this post, is the same as that of this press release on LNER.
This is the sub-heading.
LNER, Network Rail and Mobile Network Operators (MNOs) are collaborating to improve mobile connectivity on the East Coast Main Line.
These three paragraphs outline the project.
The joint project, which is delivering new mobile phone infrastructure into tunnels outside London King’s Cross station, has reached an important milestone, with the installation of a bespoke antenna. The work inside Gasworks and Copenhagen tunnels will mean most customers can expect a more reliable and consistent mobile phone and on-train Wi-Fi connection and see the removal of ‘not-spots’ customers can experience when travelling through the tunnels.
The successful delivery of the project, funded by LNER working in collaboration with Network Rail and major mobile network operators, will mean the tunnels will be the first on the country’s operational railway to be fitted with the bespoke solution, with the system installed by rail connectivity and technology integration specialist Linbrooke. Rigorous testing has been carried out at Network Rail’s Innovation and Development Centre between Network Rail and the phone companies before introduction onto the network.
The technology will mean from later this year most customers will be able to maintain direct voice and data access to their mobile provider, keeping their calls connected and meetings online as they approach and leave the capital.
Anything that improves connectivity is to be welcomed.
