Proposed High-Speed Two Services Are Not Complete
This diagram shows High Speed Two services.
Note.
- Trains to the left of the vertical black line are Phase 1 and those to the right are Phase 2.
- Full-Size trains are shown in blue.
- Classic-Compatible trains are shown in yellow.
- The dotted circles are where trains split and join.
- In the red boxes routes alternate every hour.

Are The Services Incomplete Or Has Someone Left Something Out?
Look at trains 4, 5 and 6.
- Train 4 is a pair of Classic-Compatible trains, which split at Crewe, with one going to Liverpool Lime Street and the other to Lancaster.
- Train 5 is a single Classic-Compatible train, that goes to Liverpool Lime Street.
- Train 6 is a single Classic-Compatible train, that goes to Macclesfield.
As an example, Train 5 could be a pair of Classic-Compatible trains, which split at Crewe, with one going to Liverpool Lime Street and the other to Chester, Llandudno, Bangor and Holyhead. I actually believe that this would be a way of creating a low-carbon route to Dublin, with a zero-carbon high-speed ferry from Holyhead.
What to do with Train 6 is more difficult.
- Stafford and Stoke need to be served by High Speed Two.
- Stafford, Stoke and Macclesfield are not stations with long platforms, so may not be suitable places to split a pair of Classic-Compatible trains.
- Places North of Macclesfield to terminate trains are not numerous and probably only Manchester and Huddersfield may be suitable.
The alternative might be to split a pair of Classic-Compatible trains forming Train 6 at Birmingham Interchange, one going to Stafford, Stoke and Macclesfield and the other going to Blackburn, Blackpool, Crewe, Lancaster, Liverpool or Preston
Is Liverpool Going To Get High Speed One-Point-Five?
Some of the best train journeys, I’ve ever had were not on high speed trains on specially-built tracks.
- The Thunder of Three-Thousand Three-Hundred Horses is from the early 1970s and describes a trip back from Darlington behind a Class 55 locomotive or Deltic.
- Norwich-In-Ninety Is A Lot More Than Passengers Think! describes a trip from London to Norwich and back, in the early days of the Norwich-in-Ninety timetable behind a Class 90 locomotive.
- I could add a journey on an InterCity 125 from London to Plymouth, which was running nearly thirty minutes late at Newbury, but was on time at Exeter.
The connection between these stories, was that all had a superb biological control system in the cab, who with help from the signallers was able to keep to a difficult schedule or make up time.
Last year, I made several journeys between Euston and Liverpool Lime Street. A couple of the journeys were unusual in that we arrived at our destination around six or more minutes early.
I suspect, that Avanti West Coast were experimenting to make sure that they get the new two trains per hour (tph) for the route perfect.
In Avanti West Coast Looks To Recover, I said this about Euston and Liverpool Lime Street services.
A paragraph talks about the second hourly service between London and Liverpool.
Avanti still has ambitions to introduce a second hourly service between Euston and Liverpool, but when this will come in will depend on demand recovery.
Consider.
- If would be desirable if some or all trains running on the route could achieve a timing of two hours between London and Liverpool.
- It is felt that the second service should stop at Liverpool South Parkway station, where the platforms are too short for eleven-car Class 390 trains.
- Avanti have stated they would like more stops in the Trent Valley, especially at Nuneaton, where they would connect to services to the East Midlands.
- Nuneaton is almost exactly halfway between London and Liverpool.
- Running two tph with Class 807 trains would need nine trains and Avanti have only ordered ten in total.
I believe that a practical timetable like this could work.
- Class 390 train – one tph – Non-stop or perhaps a single stop in the Midlands – Under two hours
- Class 807 train – one tph – Stopping at Nuneaton, Stafford, Crewe, Runcorn and Liverpool South Parkway – Current time or better
An hourly service between London and Liverpool in under two hours would surely be a passenger magnet.
So what is possible?
I found this service on Real Time Trains, which ran on the 16th February 2023.
- Scheduled to leave Liverpool Lime Street at 0943, but left at 1012 or 29 minutes late.
- Train did a ninety second unadvertised stop at Liverpool South Parkway. Now running 26 minutes late.
- There was a two minute stop at Runcorn and a four-minute stop at Crewe. Now running 25 minutes late
- There was a one-minute stop at Milton Keynes. Now running 20 minutes late.
- The train arrived in London Euston at 1220 or 16 minutes late.
Note.
- Liverpool Lime Street and London Euston took 2 hours and 8 minutes.
- As Liverpool Lime Street and London Euston is a distance of 193.6, a 128 minute journey is an average speed of 90.7 mph
- Liverpool Lime Street and Crewe took 32 minutes with two stops.
- Crewe and London Euston took 1 hour and 32 minutes with one stop.
- In West Coast Main Line Electro-Diesels On Test, I found that a Glasgow and London train took 1 hour and 28 minutes between Crewe and London Euston.
- All services last week had the unadvertised stop at Liverpool South Parkway
What can be deduced from these figures?
- If the Crewe stop were to be cut out, two hours and four minutes could certainly be possible between Liverpool Lime Street and London Euston with a Class 390 train.
- I also suspect that if the train were to be run non-stop, that the other four minutes could be saved.
So will Avanti West Coast run the current service using new Class 807 trains, with the extra stop at Liverpool South Parkway and perhaps other stations and the additional hourly train with a non-stop nine-car Class 390 train?
This way of delivering a two tph service would mean.
- Runcorn, Crewe and Milton Keynes would not lose any of their current fast services to and from Liverpool Lime Street and London Euston.
- Liverpool South Parkway station is probably a more convenient location for some passengers going to and from the South. It would gain an hourly service to London Euston.
- There will be an additional 77% of seats between Liverpool Lime Street and London Euston.
- Passengers who don’t like tilting trains could use the Class 807 trains.
- One tph would be timed for two hours or under and would be a marketing man’s dream.
No train would be slower than the current services.
Improvements To The Non-Stop Class 390 Train Service
I earlier said.
As Liverpool Lime Street and London Euston is a distance of 193.6, a 128 minute journey is an average speed of 90.7 mph.
An average speed of 90.7 mph, doesn’t seem fast for a Class 390 train with an operating speed of 125 mph or 140 mph under full ERTMS digital signalling.
These are some times for a selection of average speeds between Liverpool Lime Street and London Euston.
- 90 mph – 2 hours 9 minutes
- 100 mph – 1 hour 56 minutes
- 110 mph – 1 hour 46 minutes
- 120 mph – 1 hour 37 minutes
- 125 mph – 1 hour 33 minutes
- 130 mph – 1 hour 29 minutes
- 135 mph – 1 hour 26 minutes
- 140 mph – 1 hour 23 minutes
Note.
- Average speeds of upwards of 130 mph are unlikely, but I’ve added them to show that the train speed is less important than the speed of the track.
- High Speed Two’s planned time between Liverpool Lime Street and London Euston is 1 hour and 32 minutes.
But I do think times of around 1 hour and 35 minutes should be possible for non-stop Class 390 trains between Liverpool Lime Street and London Euston with an improved track and full ERTMS digital signalling.
Improvements To The Stopping Class 807 Train Service
As the track of the West Coast Main Line is improved with better track and full ERTMS digital signalling, this will also benefit the times of the stopping service run by the new Class 807 trains.
The Class 807 train with its lighter weight will have better acceleration than the current Class 390 trains. This will mean, that they will not be slowed as much, when they stop.
It may be possible to add extra stops at places like Watford Junction, Nuneaton and Stafford and still time the train for a few minutes over two hours.
Avanti West Coast Looks To Recover, is a post, that I wrote based on an interview in Modern Railways with Phil Whittingham, who is MD of Avanti West Coast.
There is a lot of talk in the article about.
- Using Nuneaton to connect the North West and the East Midlands.
- The acceleration of the Class 807 trains.
- Improving the Customer Service.
I think that Liverpool will find it is connected to more of the country on services with just a single change.
Conclusion
Liverpool is getting greater connectivity to the Midlands and the South-East of England, with times, that could be improved to be comparable with High Speed Two.
West Coast Main Line Electro-Diesels On Test
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
The first two of 13 Hitachi Class 805 electro-diesel trainsets ordered for Avanti West Coast services are undergoing testing on the West Coast Main Line ahead of entry into service later this year.
These Class 805 trains will go to places like Chester, Bangor and Holyhead via Crewe.
It is interesting to look at various Crewe to London Euston services this morning.
- 0740 – Class 390 train – From Liverpool – One Stop – 1 hour 40 minutes
- 0755 – Class 221 train – From Holyhead – One Stop – 1 hour 40 minutes
- 0832 – Class 390 train – From Manchester – One Stop – 1 hour 37 minutes
- 0844 – Class 390 train – From Glasgow – 1 hour 28 minutes
Note.
- The first field is the four-figure time that the train left Crewe.
- The last field is the journey time between Crewe to London Euston.
- The Class 390 and 805 trains will use electricity to run between Crewe and London Euston, whereas the Class 221 train will use diesel.
- Crewe and London Euston is 158 miles.
- The Glasgow train covers the 158 miles at an average speed of 107.7 mph.
I have some thoughts.
What Will Be The Time For A Class 805 Train Between Crewe And London Euston?
Consider.
- From Crewe, the Class 805 train will be using the electrification to London Euston.
- The Class 390 train can tilt, whereas the Class 805 train can’t!
- The Class 805 train is at least three tonnes lighter per car, than the Class 390 train.
- The lighter weight and possibly more power of the Class 805 trains, will give better acceleration.
- There is twenty-one years of difference in the build dates of the two trains. In that time, I also suspect that Network Rail have improved the track between Crewe and London Euston.
- Norton Bridge junction has been improved to avoid conflicts.
- It would be very convenient for Avanti West Coast and Network Rail, if the performance under electrification of the two trains were similar.
For these reasons, I believe that the performance of a non-stop Crewe And London Euston service using a Class 805 train will be such that it can match that of a Class 390 train.
I would also expect that with a similar stopping pattern between Crewe And London Euston, there would be little to choose between the two trains.
I can see with its better acceleration and lighter weight that the time between Crewe and London Euston will be perhaps a dozen minutes faster than the current time.
Using the electrification will also save a lot of diesel fuel with all its emissions.
Along The North Wales Coast Line
Consider.
- Crewe and Holyhead is 105.5 miles and takes two hours and two minutes in a typical service.
- These figures give an average speed of 52 mph.
- There are six stops, which are scheduled to take a total of ten minutes.
- About half the North Wales Coast Line has a maximum operating speed of 90 mph, but through Chester, Llandudno Junction and West of Bangor, the operating speed is 75 mph or less.
I am fairly sure, that with both the current Class 221 trains and the new Class 805 trains, it will be the track, rather than the train that determines the average speed.
It would therefore appear that if the average speed can be raised by track improvements these time savings could be achieved.
- 60 mph – 105.5 mins – 16.5 mins
- 70 mph – 90 mins – 32.5 mins
- 80 mph – 79 mins – 43 mins
- 90 mph – 70 mins – 52 mins
- 100 mph – 63 mins – 59 mins
- 110 mph – 58 mins – 64 mins
- 120 mph – 53 mins – 69 mins
- 130 mph – 49 mins – 73 mins
- 140 mph – 45 mins – 77 mins
Note.
- The first column is the average speed.
- The second column is the time between Holyhead and Crewe.
- The third column is the saving.
- I suspect that 90 or 100 mph would be the highest possible practical average speed.
- Trains average 100 mph on several long sections of the Great Eastern Main Line.
- I put in the higher speeds to show what is possible, if the North Wales Coast Line were to be converted into a 140 mph electrified line with digital signalling.
Even at these relatively slow speeds compared to High Speed Two, there are considerable time savings to be made, just by improving the tracks.
Incidentally, High Speed Two is quoted in Wikipedia as aiming for a Crewe and London Euston time of 56 minutes, so by averaging 100 mph between Crewe and Holyhead, London Euston and Holyhead could be under two hours.
Batteries And Class 805 Trains
I wouldn’t be surprised that soon after the Class 805 trains are delivered, they could be converted to a version of Hitachi’s Intercity Tri-Mode Battery Train, the specification of which is shown in this Hitachi infographic.
Note.
- I suspect that the batteries will be used to handle regenerative braking on lines without electrification, which will save diesel fuel and carbon emissions.
- The trains accelerate faster, than those they replace.
- The claimed fuel and carbon saving is twenty percent.
- It is intended that these trains will be introduced in 2023.
But Hitachi have not given any predictions of the range of these trains on battery power alone.
However, they do claim a battery range of 56 miles for the Hitachi Regional Battery Train, which is based on similar technology.
These trains could help in speeding the stops between Crewe and Holyhead.
- Batteries would be charged at Holyhead and on the electrification to the South of Crewe.
- At each stop, trains would use a proportion of the power in the battery to accelerate faster and save fuel and cut emissions.
- Battery power would be used in stations for train hotel power.
- Westbound trains would arrive in Holyhead and Southbound trains would arrive in Crewe, with not much power in the battery.
I suspect that, whether diesel or battery power is used, will be controlled by a sophisticated computerised control system.
Electrification Along The North Wales Coast Line
I think this will eventually happen to allow High Speed Two Classic-Compatible trains to run to Chester and along the North Wales Coast Line to Llandudno, Bangor and Holyhead.
But there is no benefit to be gained in electrifying until higher speeds are possible, after track improvements.
I believe these times will be possible with track improvements and the opening of High Speed Two.
- Holyhead and Crewe – Class 805 train and 80 mph average – 79 mins
- Holyhead and Crewe – Class 805 train and 90 mph average – 70 mins
- Holyhead and Crewe – High Speed Two Classic-Compatible train, electrification and 100 mph average – 63 mins
- Crewe and London Euston – Class 805 train – 80 mins
- Crewe and London Euston – High Speed Two Classic-Compatible train – 56 mins
Note, electrification will be needed, to run High Speed Two Classic-Compatible trains along the North Wales Coast Line.
I am confident that these times will be possible.
- Holyhead and London Euston – Class 805 train and 90 mph average along the coast – 2 hours 30 mins
- Holyhead and London Euston – High Speed Two Classic-Compatible train and 100 mph average along the coast – 2 hours
The current time between Holyhead and London Euston is over three hours 45 minutes.
Conclusion
These trains will certainly speed up trains to North Wales.
UK And Welsh Governments To Explore New Rail Links Between South Wales And England
The title of this post, is the same as that of this press release from the UK Government.
These are the three bullet points.
- UK and Welsh governments today (2 February 2023) announce a new study to improve transport connectivity between south-east Wales and west of England
- the study, backed by £2.7 million of UK government funding, will look at options for new railway stations and rail services on the South Wales Main Line
- this project will focus on relieving congestion on the M4, a vital connector between south Wales and the rest of the UK
The stations are not named, but it is said that they could be between Cardiff and the Severn Tunnel.
The last paragraph changes direction a bit.
Lord Peter Hendy also proposed reviewing the route connecting north Wales to the north-west of England, better connectivity with HS2 and a package of railway improvements to increase connectivity and reduce journey times between Cardiff, Birmingham and beyond.
I find this development very interesting, but typical of the sensible approach one would expect from Lord Peter.
In Could High Speed Two Serve Holyhead?, I looked at the route and came to this conclusion.
London Euston and Holyhead could be a serious proposition.
With some development and a new fast ferry, it could also open up a practical zero-carbon route between Great Britain and Ireland.
Times of four and a half hours between London Euston and Dublin could be possible.
I suspect that time would appeal to green tourists, especially those in First with a good meal.
Could The Giant Station At Bank, Liverpool Street, Monument And Moorgate Be Considered A Superhub?
In Is The City Of London Moving Towards One Giant Station?, I showed how the four stations were being drawn together and developed as one large station that served the heart of the City of London.
London is also developing other large interchange stations that could claim because of their connectivity could be classed as London superhub stations.
- Canary Wharf stations, which connect the Elizabeth and Jubilee Lines, and the Docklands Light Railway.
- Old Oak Common station, which could bring together the Central, Chiltern and Elizabeth Lines, the London Overground and High Speed Two.
- Stratford station, which connects the Central, Elizabeth and Jubilee Lines, the Docklands Light Railway, the London Overground, High Speed One and the Great Eastern Main Line.
- Whitechapel station, which connects the Circle, District, Elizabeth and Hammersmith & City Lines, and the London Overground.
But what are the characteristics of a superhub station?
A Lot Of Lines And Services
Obviously, it must have a lot of lines and services, so perhaps Clapham Junction station is the original superhub station.
All Lines Should Have Step-Free Access
This surely, goes without saying.
There Should Be Lots of Information
If the station is large it needs a lot of information and there’s probably the space to put it.
Helpful Staff
Should we have a fully-staffed kiosk at superhub stations, as there are at some main line stations?
Good Bus Connections
Bus connections at a superhub station must be comprehensive and probably connect to other superhubs.
There Should Be A Selection Of Shops For Travellers
I do my daily food and other shopping, as I travel around London. I’ll often use a station like Paddington with a good selection of shops.
Toilets
There are not enough public toilets in London.
Cash Machines
I know we’re using less cash, but a large station is a secure place to put a cash-machine.
Works Of Art
I also believe that railway stations are a secure place to put some of those large bronze sculptures and other works of art, that are currently locked away in the storerooms of galleries.
Landmark Levelling Up Fund To Spark Transformational Change Across The UK
The title of this post, is the same as that of this press release from the UK Government.
These are the four bullet points.
- More than 100 projects awarded share of £2.1 billion from Round 2 of government’s flagship Levelling Up Fund.
- Projects will benefit millions of people across England, Scotland, Wales and Northern Ireland and create jobs and boost economic growth.
- £672 million to develop better transport links, £821 million to kick-start community regeneration and £594 million to restore local heritage sites.
- Successful bids include Eden Project North in Morecambe, a new AI campus in Blackpool, regeneration in Gateshead, and rail improvements in Cornwall
The press release expands the last bullet point.
Projects awarded Levelling Up Fund money today include:
Eden Project North
Eden Project North will receive £50 million to transform a derelict site on Morecambe’s seafront into a world class visitor attraction. It will also kick-start regeneration more widely in Morecambe, creating jobs, supporting tourism and encouraging investment in the seaside town.
Note.
- Because of its closeness to the West Coast Main Line, it will have excellent rail connections to all over the North of England and Central and Southern Scotland, through Lancaster, which will only be a shuttle train away.
- One of High Speed Two’s direct destinations will be Lancaster, which will be served by High Speed Two by hourly trains to Birmingham, Carlisle, Crewe, London, Preston, Warrington and Wigan and by two-hourly trains to Edinburgh, Glasgow, Lockerbie and Motherwell.
- London and Lancaster will be a journey of just two hours and three minutes.
I believe that this high quality rail access will ensure the success of the Eden Project North.
Cardiff Crossrail
Cardiff Crossrail has been allocated £50 million from the fund to improve the journey to and from the city and raise the economic performance of the wider region.
The Cardiff Crossrail is obviously a good project from the little that I’ve read about it. But it does need a web site to explain the reasoning behind it.
Blackpool Multiversity
Blackpool Council and Wyre Council will receive £40 million to deliver a new Multiversity, a carbon-neutral, education campus in Blackpool’s Talbot Gateway Central Business District. This historic funding allows Blackpool and The Fylde College to replace their ageing out-of-town centre facilities with world-class state-of-the-art ones in the heart of the town centre. The Multiversity will promote higher-level skills, including automation and artificial intelligence, helping young people secure jobs of the future.
Blackpool certainly needs something.
My suggestion in Blackpool Needs A Diamond, was to build a second Diamond Light Source in the North to complement the successful facility at Harwell.
I don’t think the two proposals are incompatible.
Fair Isle Ferry
Nearly £27 million has been guaranteed for a new roll-on, roll-off ferry for Fair Isle in the Shetland Islands. The service is a lifeline for the island, supporting its residents, visitors and supply chains, and without its replacement the community will become further isolated.
Note.
- Will it be a British-built ferry?
- Will it be hydrogen-powered? After all by the time it is built, the Northern Scottish islands will be providing enough of the gas to power a quarter of Germany.
- Surely, a hydrogen-powered roll-on, roll-off ferry will be a tourist attraction in its own right.
I hope the Government and the islanders have a good ship-yard lined up
Gateshead Quays And The Sage
A total of £20 million is going towards the regeneration of Gateshead Quays and the Sage, which will include a new arena, exhibition centre, hotels, and other hospitality. The development will attract nearly 800,000 visitors a year and will create more than 1,150 new jobs.
I don’t know much about the Sage, but this project seems very reasonable.
Mid-Cornwall Metro
A £50 million grant will help create a new direct train service, linking 4 of Cornwall’s largest urban areas: Newquay, St Austell, Truro, and Falmouth/Penryn. This will level up access to jobs, skills, education, and amenities in one of the most economically disadvantaged areas in the UK.
I wrote about this scheme in The Proposed Mid-Cornwall Metro, where I came to this conclusion.
I believe that a small fleet of Hitachi Regional Battery Trains could create an iconic Metro for Cornwall, that would appeal to both visitors and tourists alike.
Judging by the recent success of reopening the Dartmoor Railway to Okehampton in Devon, I think this scheme could be a big success. But it must be zero-carbon!
Female Changing Rooms For Northern Ireland Rugby
There is £5.1 million to build new female changing rooms in 20 rugby clubs across Northern Ireland.
Given the popularity of the female version of the sport in England, Scotland and Wales, perhaps this is a sensible way to level it up in Northern Ireland. As rugby is an all-Ireland sport, perhaps the Irish have already sorted the South?
HS2 Smashes Carbon Target
The title of this post, is the same as that of this article on Rail Engineer.
This is a must-read article which explains how the various companies building High Speed Two are progressing in making all of the work sites diesel-free.
GeoPura is mentioned in the article and on this page on GeoPura’s case studies, which is entitled HS2 Reveals Successful Results Of Hydrogen Generator Trial, full details of the trial are given.
An HS2 construction site in London has held successful trials for two zero-emissions hydrogen fuel cell-based electricity generators – cutting carbon and improving air quality for workers and the local community.
The two GeoPura 250kVA hydrogen power units (HPUs) were trialled over the last year at HS2’s Victoria Road Crossover Box in Ealing, as a direct replacement for diesel generators to power machinery on the site.
There is also this video from High Speed Two.
Note.
- The use of electric cranes, diggers, dump trucks.
- The red trailer with lots of small cylinders, which is used to supply hydrogen.
- HS2 are also using HVO and flywheels to store energy.
- The video is narrated by HS2’s Air Quality Manager. If every project had one of these, it must surely speed decarbonisation.
We need more electric construction.
Concretene Cements Its Future With £8m Funding
The title of this post, is the same as that of this article in The Times.
This is a precis. which explains what Concretene have done.
Concretene combines graphene with concrete to form a “stronger, more sustainable and more cost-effective alternative” to the world’s most-used building material.
The eight million funding is mainly to be used for more tests.
Is Concrete The New Wonder Material?
I once lived in a concrete apartment and although it is now fifty years old, it still looks the same, as it did the day it was built.
Cromwell Tower
Cromwell Tower in The Barbican may have been built to a high specification, but we don’t hear cancer, cladding, damp, fire or mould problems about the City of London’s flagship housing estate.
In the last few years, concrete has been able to be 3D-printed, so it can now be produced in different shapes.
All these wall and roof panels on the Elizabeth Line were made by 3D-printing of concrete.
The technique also seems to be being used on High Speed Two.
These innovative uses of concrete have led to research into the manufacture and use of concrete.
These posts are must-reads.
- Carbon-Neutral Concrete Prototype Wins €100k Architecture Prize For UK Scientists
- UK Cleantech Consortium Awarded Funding For Energy Storage Technology Integrated With Floating Wind
- New HS2 Pilot Project Swaps Steel For Retired Wind Turbine Blades To Reinforce Concrete
- Earth Friendly Concrete
- HS2 Utilising UK-First Pioneering 3D Concrete Printing On Project
- Carbon Capture From Cement Manufacturing Nears Market Readiness
- Mineral Carbonation International Win COP26 Clean Energy Pitch Battle
The number of these posts show how much research is going into cutting the massive amount of carbon dioxide emitted by the concrete industry.
I also feel that some could work together.
Earth Friendly Concrete is a replacement for normal concrete, so perhaps it could be enhanced with graphene, to create an Earth Friendly Concretene.
Striking “Bellingham” Bridge Set To Light Up HS2’s Gateway Into Birmingham
The title of this post, is the same as that of this news item from High Speed Two.
These three paragraphs describe the bridge in detail.
HS2 Ltd has revealed designs for the 150-metre section of viaduct as part of the approach to Birmingham’s new Curzon Street Station, including a 25-metre-high truss which will create a new icon on the city’s skyline.
A unique light installation, designed by British artist Liz West, will introduce a dynamic colour palette to the apertures of the steel truss, framing views of the city. Titled Out of the Blue, the proposed artwork will establish the bridge as a stunning feature of the city’s landscape both during the day and at night, when the artwork will come to life.
The Curzon 2 bridge, which has been nicknamed “The Bellingham Bridge” by the team in honour of England superstar and Stourbridge-born Jude Bellingham’s performances at the World Cup, is the tallest structure in the sequence of viaducts and structures that make up the Curzon Street Approaches. These Approaches take HS2 into Birmingham’s new city centre station. The bridge consists of a gently curved truss in weathering steel which carries HS2 over the Victorian brick rail viaduct below.
There are several more visualisations on the High Speed Two web site.
Low Carbon Construction Of Sizewell C Nuclear Power Station
Sizewell C Nuclear Power Station is going to be built on the Suffolk Coast.
Wikipedia says this about the power station’s construction.
The project is expected to commence before 2024, with construction taking between nine and twelve years, depending on developments at the Hinkley Point C nuclear power station, which is also being developed by EDF Energy and which shares major similarities with the Sizewell plant.
It is a massive project and I believe the construction program will be designed to be as low-carbon as possible.
High Speed Two is following the low-carbon route and as an example, this news item on their web site, which is entitled HS2 Completes Largest Ever UK Pour Of Carbon-Reducing Concrete On Euston Station Site, makes all the right noises.
These three paragraphs explain in detail what has been done on the Euston station site.
The team constructing HS2’s new Euston station has undertaken the largest ever UK pour of Earth Friendly Concrete (EFC) – a material that reduces the amount of carbon embedded into the concrete, saving over 76 tonnes of CO2 overall. John F Hunt, working for HS2’s station Construction Partner, Mace Dragados joint venture, completed the 232 m3 concrete pour in early September.
The EFC product, supplied by Capital Concrete, has been used as a foundation slab that will support polymer silos used for future piling works at the north of the Euston station site. Whilst the foundation is temporary, it will be in use for two years, and historically would have been constructed with a more traditional cement-based concrete.
The use of the product on this scale is an important step forward in how new, innovative environmentally sustainable products can be used in construction. It also helps support HS2’s objective of net-zero construction by 2035, and achieve its goal of halving the amount of carbon in the construction of Britain’s new high speed rail line.
Note.
- Ten of these slabs would fill an Olympic swimming pool.
- I first wrote about Earth Friendly Concrete (EFC) in this post called Earth Friendly Concrete.
- EFC is an Australian invention and is based on a geopolymer binder that is made from the chemical activation of two recycled industrial wastes; flyash and slag.
- HS2’s objective of net-zero construction by 2035 is laudable.
- It does appear that this is a trial, but as the slab will be removed in two years, they will be able to examine in detail how it performed.
I hope the Sizewell C project team are following High Speed Two’s lead.
Rail Support For Sizewell C
The Sizewell site has a rail connection and it appears that this will be used to bring in construction materials for the project.
In the January 2023 Edition of Modern Railways, there is an article, which is entitled Rail Set To Support Sizewell C Construction.
It details how sidings will be built to support the construction, with up to four trains per day (tpd), but electrification is not mentioned.
This is surprising to me, as increasingly, big construction projects are being managed to emit as small an amount of carbon as possible. Sizewell C may be an isolated site, but in Sizewell B, it’s got one of the UK’s biggest independent carbon-free electricity generators a couple of hundred metres away.
The writer of the Modern Railways article, thinks an opportunity is being missed.
I feel the following should be done.
- Improve and electrify the East Suffolk Line between Ipswich and Saxmundham Junction.
- Electrify the Aldeburgh Branch Line and the sidings to support the construction or agree to use battery-electric or hydrogen zero-carbon locomotives.
Sizewell C could be a superb demonstration project for low-carbon construction!
Sizewell C Deliveries
Sizewell C will be a massive project and and will require a large number of deliveries, many of which will be heavy.
The roads in the area are congested, so I suspect rail is the preferred method for deliveries.
We already know from the Modern Railways article, that four tpd will shuttle material to a number of sidings close to the site. This is a good start.
Since Sizewell A opened, trains have regularly served the Sizewell site to bring in and take out nuclear material. These occasional trains go via Ipswich and in the last couple of years have generally been hauled by Class 88 electro-diesel locomotives.
It would be reasonable to assume that the Sizewell C sidings will be served in the same manner.
But the route between Westerfield Junction and Ipswich station is becoming increasingly busy with the following services.
- Greater Anglia’s London and Norwich services
- Greater Anglia’s Ipswich and Cambridge services
- Greater Anglia’s Ipswich and Felixstowe services
- Greater Anglia’s Ipswich and Lowestoft services
- Greater Anglia’s Ipswich and Peterborough services
- Freight services serving the Port of Felixstowe, which are expected to increase significantly in forthcoming years.
But the Modern Railways article says this about Saxmundham junction.
Saxmundham junction, where the branch meets the main line, will be relaid on a slightly revised alignment, retaining the existing layout but with full signalling giving three routes from the junction protecting signal on the Down East Suffolk line and two in the Down direction on the bidirectional Up East Suffolk line. Trap points will be installed on the branch to protect the main line, with the exit signal having routes to both running lines.
Does the comprehensive signalling mean that a freight train can enter or leave the Sizewell sidings to or from either the busy Ipswich or the quieter Lowestoft direction in a very safe manner?
I’m no expert on signalling, but I think it does.
- A train coming from the Lowestoft direction needing to enter the sidings would go past Saxmundham junction on the Up line. Once clear of the junction, it would stop and reverse into the branch.
- A train coming from the Ipswich direction needing to enter the sidings would approach in the wrong direction on the Up line and go straight into the branch.
- A train leaving the sidings in the Lowestoft direction would exit from the branch and take the Up line until it became single track. The train would then stop and reverse on to the Down line and take this all the way to Lowestoft.
- A train leaving the sidings in the Ipswich direction would exit from the branch and take the Up line all the way to Ipswich.
There would need to be ability to move the locomotive from one end to the other inside the Sizewell site or perhaps these trains could be run with a locomotive on both ends.
The advantage of being able to run freight trains between Sizewell and Lowestoft becomes obvious, when you look at this Google Map, which shows the Port of Lowestoft.
Note.
- The Inner Harbour of the Port of Lowestoft.
- The East Suffolk Line running East-West to the North of the Inner Harbour.
- Lowestoft station at the East side of the map.
I doubt it would be the most difficult or expensive of projects to build a small freight terminal on the North side of the Inner Harbour.
I suspect that the easiest way to bring the material needed to build the power station to Sizewell would be to do the following.
- Deliver it to the Port of Lowestoft by ship.
- Tranship to a suitable shuttle train for the journey to the Sizewell sidings.
- I estimate that the distance is only about 25 miles and a battery or hydrogen locomotive will surely be available in the UK in the next few years, that will be able to provide the motive power for the return journey.
In The TruckTrain, I wrote about a revolutionary freight concept, that could be ideal for the Sizewell freight shuttle.
In addition, there is no reason, why shuttle trains couldn’t come in from anywhere connected to the East Suffolk Line.
Zero-Carbon Construction
Sizewell C could be the first major construction site in the UK to use electricity rather than diesel simply because of its neighbour.
Conclusion
I shall be following the construction methods at Sizewell C, as I’m fairly sure they will break new ground in the decarbonisation of the Construction industry.
