Could High Speed Two Have An Underground Station In London?
The Achievement Of The Bank Station Upgrade
This map from OpenRailwayMap shows the lines through Bank and Monument stations.
Note.
- All the pink lines are the lines of the London Underground.
- The line running alongside London Bridge is the Northern Line, which is deep under the Thames.
- The mauve lines are those with the slightly higher voltage of the UK National Rail network going into Cannon Street station.
In part of the Bank Station Upgrade, a new Southbound tunnel for the Northern Line was dug, so that the Northern Line platforms at Bank station could be farther apart.
This visualisation shows the station.
The project was an amazing demonstration of what is possible to be achieved in underground construction.
- There is a moving walkway to move passengers between the Central and Northern Lines.
- There are escalators and lifts everywhere.
It was also dug out from London’s helpful soils under scores of important buildings, many of which are listed.
These pictures give a flavour of the underground section of the completed upgrade.
These pictures show the buildings on top of the complex.
Note.
- There is no building of any great height above the station complex.
- There are a lot of quality buildings.
- During all the work underground, I didn’t see any reports of any problems with the buildings on top.
- In How Many Entrances And Exits Does A Station Need?, I counted that the complex now has twenty entries.
It is probably a project that could be repeated elsewhere.
Camden Town, Holborn and Bond Street/Oxford Circus are probably suitable cases for treatment.
Weston Williamson’s Plan For Manchester Piccadilly Station
In The Rival Plans For Piccadilly Station, That Architects Say Will ‘Save Millions’, I wrote about Weston Williamson’s plan for Manchester Piccadilly station.
This was their visualisation.
Note.
- In the visualisation, you are observing the station from the East.
- The existing railway lines into Piccadilly station are shown in red.
- Stockport and Manchester Airport are to the left, which is to the South.
- Note the dreaded Castlefield Corridor in red going off into the distance to Oxford Road and Deansgate stations.
- The new high speed lines are shown in blue.
- To the left they go to Manchester Airport and then on to London, Birmingham and the South, Warrington and Liverpool and Wigan, Preston, Blackpool, Barrow-in-Furness, the North and Scotland.
- To the right, they go to Huddersfield, Bradford, Leeds, Hull and the North East, and Sheffield, Doncaster and the East.
- Between it looks like a low-level High Speed station with at least four tracks and six platforms.
- The Manchester Metrolink is shown in yellow.
The potential for over-site development is immense. If the Station Square Tower was residential, the penthouses would be some of the most desirable places to live in the North.

Could High Speed Two Have An Underground Station In London?
Look at this map from OpenRailwayMap.
Note.
- Euston station is in the North-West corner of the map.
- St. Pancras and King’s Cross stations can just be seen at the top of the map.
- All lines shown in red have 25 KVAC overhead electrification.
- All lines shown in pink are the London Overground.
- The double track electrified railway meandering across the map from West to East is the Elizabeth Line.
- The pink line going down the middle of the map is the Piccadilly Line.
- The pink line going down the left of the map is the Charing Cross branch of the Northern Line.
There is a large square area to the South of Euston that doesn’t have any railways crossing it.
It is shown in this map from OpenRailwayMap.
Note.
- As before, red lines have 25 KVAC overhead electrification and pink lines are the Underground.
- The Western boundary of the area is the Charing Cross branch of the Northern Line, which runs between Euston in the North and Tottenham Court Road in the South.
- The Eastern boundary of the area is the Piccadilly Line, which runs between King’s Cross in the North and Holborn in the South.
- The Northern boundary of the area is the sub-surface Circle, Hammersmith & City and Metropolitan Lines, which runs between Warren Street in the West and King’s Cross in the East.
- The Northern and Victoria Lines also run East-West to the North of the sub-surface lines.
- The Southern boundary of the area is the Central and Elizabeth Lines, which run between Tottenham Court Road in the West and Holborn in the East.
It is a substantial area.
So could it be hollowed out to create a below-ground London terminal for High Speed Two?
I got a bus from Tottenham Court Road to Euston station and then walked to Holborn, taking these pictures.
Note.
- There are only two buildings in the area with more than about six floors; University College Hospital and Senate House.
- There a lot of green spaces.
- Bloomsbury Square does have a car park beneath it.
I wonder if a terminal station could be build under the area?
- I suspect if you went fifty metres down there could be plenty of space, that could be excavated.
- Tunnels with moving walkway and escalators could link the station to the Central, Circle, Elizabeth, Hammersmith and City, Metropolitan, Northern and Piccadilly Lines.
- There would be space to have 400 metre long platforms.
- As all trains would be electric, there would be no fume problems.
- There could be lifts and escalators to the green spaces on the top.
I have a feeling that most of people living or working inside the North and South Circular Roads could get to the station by public transport with at most a single change.
World’s First Unmanned HVDC Offshore Platform Installed At World’s Largest Offshore Wind Farm
The title of this post, is the same as that of this news item from the Dogger Bank wind farm web site.
These are the two bullet points.
- Dogger Bank Wind Farm will be first UK High Voltage Direct Current (HVDC) connected offshore wind farm
- 70% reduction in topside weight per MW for offshore platforms
These are my thoughts.
High Voltage Direct Current
Wikipedia has an excellent entry on high voltage direct current, which is commonly referred to as HVDC.
The news item says this about how the electricity is brought ashore from the Dogger Bank wind farm.
The innovative offshore platform has a lean design and is the first unmanned HVDC platform which will be operated from shore and accessed only by a Service Operations Vessel. The platform will receive 1.2GW of AC power from Dogger Bank A’s 95 offshore wind turbines and convert it to DC, which will then be sent ashore to an onshore convertor station near Beverley in East Riding of Yorkshire.
Fitted with Hitachi Energy’s latest generation HVDC converter technology, Dogger Bank will be the first offshore wind project in the UK to use this technology to transmit the electricity produced back to shore, ensuring that the electricity is transmitted efficiently over long distances while minimising losses.
Note.
- Wind turbines generate AC.
- There will be conversion to DC on the substation and conversion back to AC onshore.
- It should also be noted, that large undersea interconnectors are generally built around HVDC technology.
Wikipedia says this about the advantages of DC transmission.
A long-distance, point-to-point HVDC transmission scheme generally has lower overall investment cost and lower losses than an equivalent AC transmission scheme. HVDC conversion equipment at the terminal stations is costly, but the total DC transmission-line costs over long distances are lower than for an AC line of the same distance. HVDC requires less conductor per unit distance than an AC line, as there is no need to support three phases and there is no skin effect.
Depending on voltage level and construction details, HVDC transmission losses are quoted at 3.5% per 1,000 km (620 mi), about 50% less than AC (6.7%) lines at the same voltage. This is because direct current transfers only active power and thus causes lower losses than alternating current, which transfers both active and reactive power.
It looks like cost is a big factor.
My knowledge of grid systems and AC power is limited, as I was more of a Control Engineering and Electronics student at university.
But could HVDC-connected wind farms have advantages, when it comes to providing a reactive power capability to the grid, as I wrote about in Dogger Bank C In UK Offshore Wind First To Provide Reactive Power Capability.
Extra income is another good reason to choose something.
Lightweight Platforms
I’ve always been a fan of lightweight structures and it does seen that the engineers of the Dogger Bank Wind Farm have gone down that route.
This is a paragraph from the news item.
The platform will be controlled from shore and by removing the need for personnel to stay on the platform meant it has been possible to eliminate elements such as the living quarters, helideck and sewage systems, resulting in a 70% reduction in weight (per megawatt) of the topside compared to previous platforms installed, and cost savings of hundreds of millions of pounds.
Again costs are being reduced and profits increased.
We should never rule out the importance of the finances of a project. Once by simulating a chemical process on the computer for ICI, I knocked ten metres off the height of a chemical plant. I got a nice little bonus for that!
If they have made a substantial reduction in substation weight, this surely means that the supporting structure can probably be smaller and less costly.
Conclusion
I suspect, a lot more wind farms will follow the Dogger Bank example.
Merseyrail Grand National Journeys Exceed 105,000
The title of this post, is the same as that of this article on the Liverpool Business News.
This is the first paragraph.
Train operator Merseyrail records more 105,000 passenger journeys made by racegoers during the three-day Grand National festival – and it gave away 4,000 pairs of flip-flops.
These are some points from the rest of the article.
- Many were carried on the new 777 Class trains.
- Merseyrail increased the number of trains during the three days and, at times, was running a seven-and-a-half-minute frequency.
- There was live music and entertainment for passengers at Aintree station.
- £4,200 was raised by charitable collections at the station.
It looks like a lot of people had a good time.
It was probably all good practice for Eurovision.
Businesses Back Hydrogen Trials To Accelerate Net Zero Ambitions
The title of this post, is the same as that of this news item on Centrica.
These are the three main findings of a business survey, to ascertain attitudes to hydrogen.
- Three quarters (77%) of businesses back hydrogen as part of their energy improvement strategy with a quarter (27%) intending to trial or implement it in the next two years.
- Almost one in ten (8%) respondents say they have already installed hydrogen-ready combined heat and power (CHP) units.
- A third (33%) of firms say energy costs are motivating them to adopt hydrogen.
This paragraph details who were surveyed.
We surveyed 500 executives in December 2022 and January 2023 across food and beverage manufacturing, healthcare, hospitality and travel, pharmaceutical manufacturing, heavy industry, horticulture and light industry. 24% of respondents were from the UK, 16% Ireland, 20% Netherlands, 20% Italy, 20% Hungary.
It certainly looks to be a well-constructed survey, with a wide range of respondents.
I have some thoughts.
Centrica And Combined Heat And Power
I was initially surprised that eight percent of respondents had already installed hydrogen-ready combined heat and power units.
But according to Centrica Announces Hydrogen Ready Combined Heat And Power Partnership With 2G, Centrica are preparing themselves for selling systems in this area.
Businesses Are Certainly Looking At Hydrogen
A figure of 77 % of businesses are looking at hydrogen and 27 % are investing in hydrogen.
But I don’t think the average man on the Clapham Omnibus would be so enthusiastic.
Costs Are Motivating Firms To Adopt Hydrogen
I would be surprised if costs didn’t have an effect.
But if costs are driving them towards hydrogen, then hydrogen must be more affordable.
Which is one in eye for hydrogen deniers, who always tell me it is more expensive.
Are Centrica Working To Drop Their Costs?
These posts would suggest they are.
- Centrica And Ryze Agree To Develop Hydrogen Pathway
- Centrica Announces Hydrogen Ready Combined Heat And Power Partnership With 2G
- Centrica Partners With Hull-Based HiiRoc For Hydrogen Fuel Switch Trial At Humber Power Plant
- Centrica Plan Green Energy Hub At Former Gas Power Plant
- Centrica Re-Opens Rough Storage Facility
- Lhyfe And Centrica To Develop Offshore Renewable Green Hydrogen In The UK
They are doing deals with start-ups and repurposing old plants and pipelines.
Conclusion
Centrica seem to be leading the charge to hydrogen in the UK.
Denmark Launches World’s First Power-to-X Tender
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Danish Energy Agency (DEA) has invited bids to build and operate Power-to-X projects with a deadline for applications set to 1 September. Through the tender – the first of this kind in both Denmark and the world – the country has made available DKK 1.25 billion (approximately EUR 167.7 million) in state support for the production of Power-to-X in the form of green hydrogen.
This paragraph outlines the deal.
The tender is being held to procure hydrogen produced by using renewable energy sources and is part of Denmark’s goal to reach between 4 and 6 GW of electrolysis capacity by 2030 and its Power-to-X strategy, released in 2021, according to which the country’s offshore wind resources provide good conditions for the production of green hydrogen, which requires large amounts of green electricity.
These are the conditions.
- Only hydrogen that is produced from renewable energy sources and meets the EU’s documentation requirements for green PtX fuels is eligible for support.
- The winning bidder(s) must have the project(s) built to full capacity and start green hydrogen production within four years of signing the contract with the Danish Energy Agency.
The tender has been approved for state aid by the European Commission.
I can see all the large electrolyser builders getting their bids ready for what will be tough competition.
Overview – Siemens Energy Electrolyser Deal Dwarfs Rest In Q1 2023
The title of this post is the same as that of this article on Renewables Now.
This is the first paragraph.
The global electrolyser market concluded the first quarter of 2023 with a variety of equipment supply deals, partnerships, framework agreements and even some firm contracts. Siemens Energy stood out with the news of its selection to equip a “world-scale” eFuels facility in Texas with a total capacity of 1,800 MW.
The article is a good summary of the electrolyser market.
Devizes Station Would Need To Be Part Of Wider Rail Plan
The title of this post, is the same as that of this article on Railway Gazette.
These two paragraphs outline the current status.
The construction of a Devizes Gateway station at Lydeway is unlikely to represent value for money as a standalone project, but it could be viable as part of a wider rail improvement programme, a study has concluded.
The feasibility study undertaken by Wiltshire Council, Devizes Development Partnership, GWR and Network Rail built on a strategic outline business case submitted to the Department for Transport under the Restoring Your Railway Fund programme in November 2021.
The Department for Transport will now decide what to do next.
I think there are other issues on the route between Reading and Taunton.
The Current Train Service
The only passenger services using the Reading and Taunton route are these three trains, which all have a frequency of one train per two hours (tp2h).
- London Paddington and Exeter St. Davids – Calling at Reading, Newbury, Hungerford, Pewsey, Westbury, Castle Cary, Taunton and Tiverton Parkway
- London Paddington and Plymouth – Calling at Reading, Taunton, Tiverton Parkway and Exeter St Davids
- London Paddington and Penzance – Calling at Reading, Taunton, Tiverton Parkway and Exeter St Davids
Note.
- London Paddington and Exeter St. Davids takes a few minutes over two hours.
- London Paddington and Plymouth takes a few minutes over three hours.
- London Paddington and Penzance takes a few minutes over five hours.
- The Reading and Taunton route is a double-track railway with a 110 mph operating speed.
- London Paddington and Newbury is electrified.
- The last two trains alternate to give Plymouth an hourly service.
- After Exeter St. Davids, trains have a sophisticated stopping pattern to give all stations served a good service.
From several trips along the line, I have the impression, that it’s a route, where drivers can get the best out of the trains.
Electrification
The line would benefit from electrification, in terms of journey times and decarbonisation.
But could this route be run by battery-electric trains?
- It is 89.7 miles between Newbury and Taunton.
- It is 120.4 miles between Newbury and Exeter St. Davids.
- It is 52.1 miles between Exeter St. Davids and Plymouth.
- It is 79.4 miles between Plymouth and Penzance.
- London Paddington and Newbury is electrified.
- Taunton, Exeter St. Davids, Plymouth and Penzance stations could have a charging system of some sort.
This Hitachi infographic shows the specification of the Hitachi Intercity Tri-Mode Battery Train.
Consider.
- Two trains go between Newbury and Taunton without stopping.
- The Exeter St. Davids service stops three times.
- Newbury and Taunton non-stop took 75 minutes at an average speed of 72 mph
- Newbury and Taunton with three stops took 78 minutes.
- All trains currently appear to be nine cars.
I suspect that Hitachi’s Intercity Tri-Mode Battery Train could go between Newbury and Taunton with a great deal of ease.
How many diesel engines and batteries would the train have?
Normally, nine-car Class 800/802 trains have five diesel engines.
So how many will be replaced by batteries?
The infographic says one engine will be replaced, so if that is a five-car train, it looks likely that a nine-car train could have two batteries.
But Hitachi could be playing a long game!
In Stadler FLIRT Akku Battery Train Demonstrates 185km Range, I wrote about how the FLIRT Akku has a range of 115 miles.
If Hitachi can squeeze 125 miles out of a nine-car Class 800 with two or three battery packs, they will outrange the FLIRT Akku and be able to run between London Paddington and Penzance on batteries, with some topping up on the way.
We mustn’t forget the engineers at Hyperdrive Innovation, who are designing and building Hitachi’s battery packs.
They will be ultracompetitive and know the range required to get battery-electric trains to Penzance.
I suspect that when the range of the nine-car battery-electric Class 800/802 is revealed, it will astonish everybody!
Bedwyn Station
Bedwyn station is served by an hourly shuttle train to and from Newbury, run by a diesel train.
The station used to have a direct service from London, but now passengers change at Newbury.
A Station For Marlborough
I investigated this in A Station For Marlborough, where this was my conclusion.
With the next generation of electric train with onboard energy storage or IPEMUs, a Marlborough station on a new Marlborough Branch Line can be used to create a two tph service to and from Paddington to replace the current one tph service from Bedwyn.
So a new Marlborough station would be a win for all those using stations on the Reading to Taunton Line to the East of Pewsey.
I also wonder how many other similar services can be developed by extending a service past a main line terminal to a new or reopened branch line, which is built without electrification and run using trains with onboard energy storage.
In answer to my posed question in the last paragraph, I suspect it is quite a few!
Devizes Gateway Station At Lydeway
I wrote about this proposed Devizes Gateway station in Reinstatement Of Rail Access To Devizes Via A New Station At Lydeway.
After writing Was Baldrick An Essex Man? about the building of an avoiding line at the new Beaulieu Park station North of Chelmsford, I do wonder, if it would be an idea to incorporate one in this proposed station, if there is a need to increase capacity.
This Google Map shows the station site, where the A342 crosses the railway.
I suspect a third track can be squeezed in.
Westbury Station
Westbury station is a busy station, where the Reading and Taunton Line crosses the Wessex Main Line.
This map from OpenRailwayMap shows the lines in the station.
Note.
- The blue lettering indicates Westbury station.
- The two major rail routes are shown in orange.
- The Reading and Taunton Line goes East-West across the map.
- Note the avoiding line South of Westbury station.
- Reading is in the East and Taunton is in the West.
- The Wessex Main Line goes North-South across the map.
- Bristol is in the North.
- Salisbury and Southampton is in the South.
In Westbury Station – 30th July 2020, there are some pictures I took of Westbury station.
This section in Wikipedia says this about the Future of Westbury station.
The line to Westbury is not due to be electrified as part of the 21st-century modernisation of the Great Western Main Line. Although local councillors support it, the extension of electrification beyond Newbury to Westbury was assessed as having a benefit–cost ratio of only 0.31.
On the other hand this document on the Network Rail web site, which is entitled the Devizes Gateway Interim
Feasibility Study, suggests that another platform might be added at Westbury station.
Castle Cary Station
Castle Cary station doesn’t seem to have any well-publicised problems, so please tell me if you know of any.
Frome Station
Frome station is described in its Wikipedia entry as an unusual station and one that is Grade II Listed.
I suspect, it could do with some more services.
Somerton Station
I wrote about a new Somerton station in Somerset: Plans For New Railway Station On Levels.
Track Improvements
I suspect if Network Rail were improving the route between Reading and Taunton, they know of some places, where they could do some work.
Service Improvements
Consider.
- There is probably a need for a stopping train between Newbury and Taunton, which calls at all stations.
- It might terminate at the London end, at either London Paddington or Reading.
- It might be a battery-electric train.
- An hourly frequency would be ideal, if the track and signalling could handle it.
- Charging systems would be positioned as needed.
The train would interface with other Great Western services to Bristol, London Paddington, Gloucester, Salisbury, Southampton and Weymouth.
Oy could also interface with the Transwilts services.
Conclusion
This could be developed into a very useful network for Wessex.
SSE To Help Decarbonise 5000 Homes In Major London Retrofit Project
The title of this post, is the same as that of this news item on SSE.
These three paragraphs outline the work.
SSE Energy Solutions has agreed a deal with Berkeley Homes that will help to decarbonise a heat network for up to 5,000 homes in London, thought to be one of the largest retrofits of its kind in the country.
An Air Source Heat Pump (ASHP) system will be installed to supply the homes on an existing district heating network at the Woolwich Arsenal site after several options were considered, including the use of waste heat and ground and river source solutions. An ASHP was chosen as the best low carbon, low tariff option over the length of the supply contract.
The system will be installed in nearby Wellington Park where a new landscape will be created through a unique planting scheme that broadens the biodiversity of the area by responding to the microclimate. The ASHP will connect directly to the existing district heating network pipes, reducing the carbon content of the heat provided by the network.
It strikes me, that no new housing estates or blocks of flats, should be built without a district heating system.
In this example, SSE are able to decarbonise a large number of houses and flats, by just replacing a boiler with an air source heat pump.
Just imagine the hassle if five-thousand individual boilers had to be replaced.
Siemens Completes Study To Decarbonise Major UK Industrial Estate By 2038
The title of this post, is the same as that of this news item on Siemens UK web site.
This is the sub-heading.
Siemens has proposed a road-map for decarbonising Trafford Park, one of Europe’s largest industrial estates, to support Trafford Council’s aims for the Greater Manchester borough to achieve net zero by 2038.
This three paragraphs outline the proposal.
The Low Carbon Trafford Park 2038 study, proposed by Siemens, aims to identify, cost and measure the impacts of low carbon technologies at the industrial estate. It covers a broad range of solutions, from waste to energy and heat recovery from energy intensive industrial players, to the potential for solar photovoltaics across the park to generate 147 GWh of clean energy.
The study acts as a blueprint for the council to consider as it works to eliminate the 714,000 tonnes of carbon emitted from Trafford Park each year. The estate is home to 1,330 businesses employing more than 35,000 people, with a dense population of industrial and commercial occupiers over an area of 4.6 sq miles.
The Council aims to use the roadmap to facilitate stakeholder engagement and collaboration across the industrial park, aligning business and environmental goals to different commercial segments across recommended technological and behavioural measures. It will then consider its broader recommendations as part of a long-term plan in partnership with occupiers.
This is decarbonisation on a grand scale!
- Siemens expects the decarbonisation of Trafford Park to attract new business to the Park and maintain and enhance its standing as a commercial and industrial hub in the region.
- The measures recommended would require £1.2 billion of private and public investment to achieve a 94% reduction in emissions.
- The study provided Trafford Council with modelling of an extensive range of measures for conserving gas and electricity and for generating clean energy on-site.
This page on the Siemens web site is entitled Smart Infrastructure For A Sustainable Future, outlines some of the company’s solutions.
Conclusion
It will be interesting to see how Trafford Park decarbonises.
