Very Light Rail Trial For Heathfield Branch?
The title of this post, is the same as that of an article in the May 2024 Edition of Modern Railways.
This is the first four paragraphs.
Investigations are ongoing as to whether the disused Heathfield branch line in Devon could be used as a test route for the Revolution Very Light Rail (RVLR) vehicle.
Heathfield Rail Link Association (HRLA) says a survey has been completed along the four-mile line from Newton Abbot, which was last used by timber trains in 2017 and hasn’t seen a regular passenger service since 1959.
The work, by Lampitt Rail, has been completed for Eversholt Rail, one of the firms behind RVLR, a hybrid vehicle, which aims to help reduce costs on existing branch lines and those earmarked for reopening.
A spokesman for Eversholt said the line is one of more than 200 potential opportunities for RVLR ahead for 2026, when it’s hoped tests will start on branch lines around the country using three new battery prototypes.
These are my thoughts and observations.
The Heathfield Branch
This OpenRailwayMap shows the Heathfield branch.
Note.
- The former site of Heathfield station is indicated by the blue arrow.
- The yellow track is the Heathfield branch.
- The orange track is the Cornwall Main Line, that goes through Newton Abbot station to Plymouth and Penzance stations.
This second OpenRailwayMap shows the track layout Newton Abbot station.
As there are three platforms, I suspect that matters can be arranged to turn an occasional train from the branch.
How Will The Revolution VLR Be Charged?
The Modern Railways article says this about charging.
Eversholt Rail and partner firm Transport Design International have stated they will build three new battery-powered vehicles for the 2026 tests, which will need rapid charging points, made up of two rails in-between the running lines which would contact a shoe hanging from the train. HRLA is working with UK Power Networks to find locations for these chargers, including at Newton Abbot.
It sounds very much like the Vivarail/GWR Fast Charge equipment.
What Will Be The Range Of The Revolution VLR?
The range of the Revolution VLR has not been stated.
But this is stated in the Modern Railways article.
Heathfield Rail Link Association (HRLA) says a survey has been completed along the four-mile line from Newton Abbot.
So will the train be able to do a round trip on one charge or just a single journey?
Or could this route be a strong possibility, as the Revolution VLR has the range to do a round trip on one charge?
Study Highlights Increased Risk Of Second Cancers Among Breast Cancer Survivors
The title of this post, is the same as that of this news story from the Cambridge University.
This is the sub-heading.
Survivors of breast cancer are at significantly higher risk of developing second cancers, including endometrial and ovarian cancer for women and prostate cancer for men, according to new research studying data from almost 600,000 patients in England.
These are the first three paragraphs of the story.
For the first time, the research has shown that this risk is higher in people living in areas of greater socioeconomic deprivation.
Breast cancer is the most commonly diagnosed cancer in the UK. Around 56,000 people in the UK are diagnosed each year, the vast majority (over 99%) of whom are women. Improvements in earlier diagnosis and in treatments mean that five year survival rates have been increasing over time, reaching 87% by 2017 in England.
People who survive breast cancer are at risk of second primary cancer, but until now the exact risk has been unclear. Previously published research suggested that women and men who survive breast cancer are at a 24% and 27% greater risk of a non-breast second primary cancer than the wider population respectively. There have been also suggestions that second primary cancer risks differ by the age at breast cancer diagnosis.
I have a few thoughts.
The Data
The story says this about the data.
To provide more accurate estimates, a team led by researchers at the University of Cambridge analysed data from over 580,000 female and over 3,500 male breast cancer survivors diagnosed between 1995 and 2019 using the National Cancer Registration Dataset. The results of their analysis are published today in Lancet Regional Health – Europe.
A large number of cases were analysed and with these types of analysis, more is definitely better.
I would hope that this study will be repeated in a few years, when more data is available.
The Death Of My Wife
This happened to my late wife.
At about 55 in 2004, my wife developed breast cancer. Strangely, it was in the same position, where a car air-bag had bruised her breast, when it went off in an accident, a few years before.
Chemotherapy was recommended and she tried one round at home, but she couldn’t get on with it.
So she eventually had a long course of radiotherapy in Harley Street going up every day on the train. She was also doing as many court cases as she could to pay for it all.
It appeared everything had worked well and in the Autumn of 2007, she was given the all clear for the breast cancer.
But in October 2007, she was diagnosed with a squamous cell carcinoma of the heart.
She died in December 2007 at just 59.
My wife’s second cancer and her death seems to fit the pattern of the patients in the news story.
My Wife’s Genetic Background
This is rather bare, as she was adopted. Although, I do have her plaits from, when the cut them off at 18, as she’d kept them and I found them after she died.
But she didn’t come from a deprived background.
I Am Coeliac
If I have one regret, it’s that I didn’t encourage her to go gluten-free after the first cancer.
It might have boosted her immune system to help.
Conclusion
Anybody, who has breast cancer must beware a second attack of cancer.
Uf it can kill my fit 59-year-old wife, it can kill anyone.
BW Ideol Unveils Mass Production-Ready Floating Wind Foundation
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
France-based BW Ideol has unveiled its standardised floating foundation product and a blueprint for mass production that could drive costs down across projects.
This is the first paragraph.
With over 22 GW already awarded in Scotland, around 8 GW in the US, and several GW currently being awarded or in the tendering phase elsewhere in the world, the floating wind is now entering an industrialization phase, said BW Ideol.
It looks like the French have come up with a solution that’s needed.
These are previous posts about BW Ideol.
- BW Ideol And Holcim To Explore Use of Low-Carbon Concrete In Floating Offshore Wind
- BW Ideol, ABP To Explore Serial Production Of Floating Wind Foundations At Port Talbot
There is also this video of proposed serial production of BW Ideol floaters at the Port of Ardersier.
This Google Map show the area of Scotland to the North-East of Inverness Airport.
Note.
- Inverness Airport indicated by the red arrow.
- Ardersier village in the middle of the map on the bay.
- Fort George is at the North end of the bay.
The Port of Ardersier is the large slab of concrete in the North-East corner of the map, the Carse of Ardersier marked below it.
BW Ideol are claimining they can build one floater a week or one GW a year.
Wrightbus Secures Further German Order For 46 Hydrogen Buses
The title of this post, is the same as that of this press release from Wrightbus.
These paragraphs outline the deal.
World-beating zero-emission bus manufacturer Wrightbus today announced a milestone deal to provide 46 hydrogen buses to Germany – taking a demo bus from Belfast to showcase its reliability and range.
The buses ordered by Cottbusverkehr GmbH will serve the city of Cottbus, the second largest city in the state of Brandenburg, and and in the western part of the district of Spree-Neiße.
It follows a landmark announcement by the German government to implement a €350 million scheme to support the production of renewable hydrogen.
Wrightbus is Europe’s fastest-growing bus manufacturer and follows the company’s rapid rise since it was bought out of administration in 2019. It was named Northern Ireland’s fastest-growing company by Growth Index this week – employing 1,650 people and producing 22 buses a week.
The Cottbus order for the Kite Hydroliner buses follow deals in Germany with West Verkehr, Regionalverkehr Köln GmbH (RVK), and Saarbahn GmbH, with more European orders in the pipeline.
If Northern Irish hydrogen buses are selling well to the Germans, why are there so few in the UK.
These pictures show the UK version of the German buses in Crawley.
They are excellent buses.
World’s First Energy Island Starts Taking Shape – Video
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The first of the 23 caissons being built for Princess Elisabeth Island in Vlissingen, the Netherlands, is almost finished and will be immersed in the North Sea this summer. The artificial Belgian energy island is a world first.
Note.
- This web site is the web site of Belgium’s Princess Elisabeth energy island.
- This YouTube video describes the Princess Elisabeth island.
The video shows the importance of this project, that will have interconnectors to both the UK and Denmark, and connections to a large number of offshore wind farms.
These two paragraphs describe the roll-out of the caissons.
When the caissons are ready, a semi-submersible vessel will transport them further down the harbour, where they will be placed in the water and temporarily stored. They will then be moved to their final location in the North Sea this summer, weather permitting.
The caissons will form the outer walls of the energy island. The island itself will be created using approximately 2.3 million square metres of sand, extracted locally. The island will be finished in late 2026, when the electrical equipment can start to be installed. Contracts for this will be tendered this year.
These pictures show four Pheonix Caissons from Mulberry Harbours that are used as a museum in The Netherlands.
Nothing is new! But at least the Belgians won’t have to tow their caissons across the Channel under enemy fire.
A Video Description Of Princess Elisabeth Island
This web site is the web site of Belgium’s Princess Elisabeth energy island.
This YouTube video describes the Princess Elisabeth island.
From the video the following can be determined.
- The Princess Elisabeth island is 45 km. from the Belgian coast.
- An interconnector to the UK could come ashore at the site of the decommissioned Bradwell nuclear power station.
- An interconnector to Denmark could come ashore in Southern Jutland, just North of where the Viking Link connects to Denmark.
This map clipped from the video shows the location of Princess Elisabeth island.
Note.
- Belgium is shown in red.
- Istend is in the middle of the straight Belgian coast.
- The red dot between Belgium and the UK is Princess Elisabeth island.
- The interconnector to the UK could feasibly go to Bradwell.
- The interconnector to Denmark could go via a wind farm, which would explain the kink.
- Could the kink point be at the Dogger Bank, where there could be 20 GW of wind farms?
Has Belgium made a bid to dominate European energy distribution?
This Google Map shows the Belgian and English coast lines.
Note.
- Bradwell is on the coast to the North-East of Southend-on-Sea.
- As it used to be a nuclear power station site it still has an electricity connection to the grid.
- The Princess Elisabeth island is 45 km. from the Belgian coast at Ostend.
I estimate that a Bradwell and Princess Elisabeth island interconnector would be about 150 miles.
Sekisui’s FFU: Newark Flat Crossing Four Years On
The title of this post, is the same as that of this article on Rail Engineer.
These two paragraphs introduce the article.
Sekisui manufactures synthetic wood baulks made from Fibre-reinforced Foamed Urethane (FFU). Network Rail engineers installed the first FFU baulks and sleepers as replacements for traditional hardwood on military canal bridges in Kent during 2014. The FFU product was first introduced on Japanese Railways in 1980 and early installations are still performing to specification. FFU is now widely used on railway infrastructure in 33 countries to support track on bridges, decking for level crossings, plain line sleepers, and switch and crossing (S&C) bearers.
Newark flat crossing is an example of a unique and large application of FFU technology on Network Rail infrastructure which required the development of the long FFU synthetic bearers forming a lattice track support 16 by 16 metres. Sekisui holds full Network Rail Product Acceptance Certification PA05/07176 for this project which became operational following complete track renewal in August 2019. The FFU was used to replace the traditional hardwood to support the track.
The article is a fascinating insight into the use of FFU.
Fabricated To Requirement
The article describes how the FFU technology was fabricated to create a replacement for all the timber in a factory in Nottingham.
This paragraph describes the advantages of FFU.
Key benefits over hardwood include longevity with over 50 years’ service life. FFU is form retentive, not prone to splitting or absorption of water, and does not rot or deteriorate in sunlight so it contributes significantly to ‘whole life cycle cost reduction’ by reducing track maintenance and renewal interventions. The product does not require maintenance inspectors to complete micro-drilling during service life and is fully recyclable.
This paragraph details a problem, that Network Rail were having with the maintenance.
Prior to the 2019 renewal, the supporting lattice that holds the cast crossings into position was made up from hardwood and typically required replacement every 15 years. The last renewal occurred in 2003. Network Rail found that procuring suitable hardwood timbers of 16 metres for a further renewal proved problematic.
This reminds me of the problems, Brunel’s successors had with his timber viaducts. They just couldn’t get the quality of timber he had been able to source.
It appears from the two pictures in the article, that FFU can be worked like hardwood.
Maintenance Comparison After Four Years
This paragraph introduces this section.
Over four years after the renewal of Newark Flat Crossing utilising FFU, Network Rail Track Maintenance Engineers (TME) in Doncaster report significant reduction in maintenance requirements.
These paragraphs compare four years of use of both systems.
2003-2007 hardwood timber renewal – track geometry deterioration, ride quality issues, splitting of timbers, failure of screws, several rail management interventions to cast crossings, including cracking of castings leading to early replacement of ironwork.
2019-2023 FFU renewal – stable track geometry with no ride quality issues reported, no screw failures, no deterioration in the FFU material, reduced rail management intervention and no cracking or premature replacement of cast crossings.It looks to me, that the FFU is a long-term cost saver.
This paragraph indicates the maintenance savings.
In terms of rail management, since the introduction of FFU, Network Rail’s TMEs have reduced the cyclical inspection and maintenance requirements from four-weekly to eight-weekly. There is now only minimal crossing nose profile grinding required and two small casting weld repairs have been done to date.
That looks like a fifty percent saving.
Other Uses Of FFU
In my 76 years, I’ve came across various uses of large timbers.
- At ICI in the late 1960s, some of the plants, I visited at Winnington, had been built from massive oak beams in the early 19th Century.
- With one plant, that ICI demolished, the oak beams were sold for a surprising amount of money.
- I’ve lived in two early 19th Century houses, that were built with oak beams.
- An architect designed a replacement barn for me, that was made of large timbers. Sadly, the new owners of the house demolished it and I don’t have any pictures.
For these reasons, I’m certain, that architects, builders and restorers can find all sorts of uses for FFU.
This is the product page.
Conclusion
This looks like a success story and the Rail Engineer article should be read in full.
It might give you very good ideas.
Denmark Launches Massive Offshore Wind Auction
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Denmark has opened a new offshore wind tender, the country’s largest ever, offering a minimum of 6 GW of new capacity spread over six wind farms, with the overplanting option allowing for 10 GW or more of new capacity to be added.
These are two paragraphs from the article.
The offshore wind farms must deliver at least 6 GW, and as a new element, there will be freedom to establish as much offshore wind as possible on the tendered areas, with the exemption of Hesselø with a maximum capacity of 1.2 GW.
If the market utilizes this freedom to optimize the usage of the areas, it could result in the construction of 10 GW offshore wind or more, the agency said.
Recently, some wind farms in the UK have been increased in size after the auction.
In Crown Estate Mulls Adding 4 GW Of Capacity From Existing Offshore Wind Projects, I note how 4 GW of overplanting could be employed to raise the total capacity from 4.6 GW to 8.6 GW.
So have the Danes decided to build expansion into the tender?
One of the wind farms in the auction is called Nordsøen I.
- It will be about 50 km. from the West Coast of Denmark.
- It appears it will have a capacity of at least 1 GW.
- It could connect to the shore, not far from where the Viking Link between Lincolnshire and Denmark connects to the Danish grid.
- There is a 700 MW interconnector between the area and Eemshaven in The Netherlands.
- There is 1.5 GW of overland transmission lines to Germany.
All these connections, increase energy security for Denmark, Germany, the Netherlands and the UK.
Could the Danes be building the Nordsøen I, so it could work with the all the connections in Southern Jutland and improve energy security?
New National Grid Substation Fully Operational, Transmitting Clean Power To 1.5 Million Homes
he title of this post, is the same as that of this press release from National Grid.
These three bullet points act as sub-headings.
- National Grid’s new Littlebrook 400kV substation in Dartford, Kent is now fully energised.
- The facility enables the transmission of 2GW of low carbon and renewable energy from interconnectors and offshore wind farms off the coast of Kent to power around 1.5 million homes.
- New technology deployed to reduce emissions at the site.
This is the first three paragraphs, which outline the project.
National Grid has successfully commissioned a new, state-of-the-art substation, in Dartford, Kent, enabling 2 gigawatts (GW) of low carbon and renewable energy to power around 1.5 million homes.
National Grid and its contractors Balfour Beatty and GE Vernova’s Grid Solutions have been working since June 2019 to build a replacement for Littlebrook 400kV substation.
The new facility will help to reduce the use of sulphur hexafluoride (SF₆), a gas commonly used in the electrical industry to prevent short circuits and to keep the network safe and reliable.
These two paragraphs explain how the new substation fits in with National Grid’s SF₆ policy.
Engineers are using GE Vernova Grid Solutions’ innovative g3 gas-insulated busbar equipment which is SF6- free. A total of 5.6 tonnes of SF₆ gas has been saved, forming part of National Grid’s ambition to reduce its SF₆ emissions by 50% by 2030 and removing all SF₆ gas from electrical assets by 2050.
Teams have also deployed net zero construction methods throughout the project to reduce the environmental impact of the works, including steel manufactured in Britain, solar powered electrics, electric vehicle charging points, biodiversity net gain plan for the local area and an onsite biodigester to manage wastewater, all saving 5229 tonnes of CO₂ emissions during construction.
National Grid have this page on their web site, which is entitled What Is SF6? Sulphur Hexafluoride Explained, where this is the first paragraph.
Sulphur hexafluoride – also known as SF6 – is a ‘greenhouse gas’ that has long played a part in global warming, similar to that of carbon dioxide (CO2).
Hence the need for its removal.
Conclusion
Removal of sulphur hexafluoride from the world’s electricity substations and switchgear will be a very large task.
BW Ideol And Holcim To Explore Use of Low-Carbon Concrete In Floating Offshore Wind
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
BW Ideol and Holcim have signed a Memorandum of Understanding (MoU) for a feasibility study on supplying beneficial low-carbon concrete for the floating offshore wind industry, with particular reference to Scotland.
These are the first three paragraphs.
BW Ideol and Holcim aim to collaborate on optimising the supply of the innovative concrete needed for the intended mass production of BW Ideol’s floaters in the Port of Ardersier.
Low-carbon concrete’s advantages as a building material for offshore wind farms include its durability in marine environments, its local availability and its comparatively lower carbon emissions, the companies said.
The collaboration includes developing specific durable maritime low-carbon concrete mixes with enhanced mechanical performance perfectly suited to slipform application.
This is surely a good development.
