New Train Service Connects Finland And Sweden For First Time In Decades
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A new passenger train linking Finland and Sweden has begun running, creating the first rail connection between northern Finland and southern Europe in nearly 40 years.
These three paragraphs add more detail.
Shortly after 05:00 local time (03:00 BST) on Monday, a double-decker train set off from the coastal Finnish city of Oulu, rumbling its way across the border to Sweden.
As the inaugural service crossed the Torne river from Finland and pulled into Sweden’s Haparanda station, it was met by crowds of people waving Finnish and Swedish flags.
The route was initially suspended in the late 1980s to the early 1990s, due to low passenger numbers and technical differences in the tracks between Finland and Europe.
This OpenRailwayMap shows the route between Oulu and Haparanda stations.
Note.
- The map is drawn by track gauge.
- Finnish gauge tracks are shown in red.
- Swedish gauge tracks are shown in black.
- The location of Oulu in Finland is shown by the blue arrow.
- The location of Haparanda in Sweden is at the Eastern end of the black track in the North-Western corner of the map.
- The route seems very much along the coast.
- I wouldn’t be surprised that the sea views are excellent.
This second OpenRailwayMap shows the route between Kemi and Haparanda stations.

- The track between Haparanda and Tornio is shown dashed red and black, as it accepts trains of both Finnish and Swedish gauges.
I have some thoughts.
Torne River Railway Bridge
This is is the first paragraph of the Wikipedia entry for the Torne River Railway Bridge.
The Torne River Railway Bridge is a dual gauge railway bridge on the Tornio–Haparanda railway between Haparanda, Sweden and Tornio, Finland; the bridge can be used by the 1524mm gauge trains of Finland, as well the 1435mm gauge trains used in Sweden. A temporary ice river track was built over the Torne River in 1917.
Note
How Do Trains Cross The Torne River Railway Bridge?
I asked Google AI the title of this section and received this answer.
Trains cross the Torne River Railway Bridge on dual-gauge tracks featuring four rails.
This setup accommodates both Finland’s wider 1,524 mm track gauge and Sweden’s standard 1,435 mm track gauge, allowing freight and specialized rail equipment to pass directly between Tornio, Finland, and Haparanda, Sweden, without stopping.
Bridge and Track Design
Dual-Gauge System: Four physical rails are laid on the bridge deck. They interlace the wide-gauge and standard-gauge tracks so different wheel sets fit.
Electrification: The 410-meter truss bridge and connecting line feature overhead catenary wires aligned with Finnish electric standards.
Control and Operations: Train movements across the bridge and its shared dual-gauge sections are managed by Finnish rail traffic control.
Cross-Border Travel
Freight Transport: Freight trains and containerized goods (such as shipments from Outokumpu) use the dual-gauge tracks to move directly between the marshalling yards of both countries.
Passenger Services: While regional passenger train connections operate across the border via the Tornio–Haparanda railway, regular passenger operations involve seamless station transfers at Haparanda rather than continuous through-running for all service types.
It is a simple but ingenious system.
I’ve never seen one anywhere else, although I have ridden on the three rail track at Zwickau.
Note.
- Standard gauge trains use the two outer rails.
- Metre gauge trams use the two far rails, which are a metre apart.
- In the UK, all modern trams are standard gauge, so we don’t have the problem.
But say a narrow-gauge heritage railway wanted to connect into a standard gauge station, I’m sure that the Zwickau system could be used.
Do Other Bridges Use The Same Interleaved Dual Gauge Track As The Torne River Railway Bridge
I asked Google AI the title of this section and received this answer.
Yes, other rail locations use an interleaved dual-gauge track setup (technically known as a gauntletted or four-rail configuration) when two track gauges are too close together to share a common rail.
Why Interleaved Tracks are Used
Gauge Proximity: When the difference between two track widths is small (such as Finland’s 1,524 mm and European standard 1,435 mm, a difference of only 89 mm), a standard three-rail shared setup cannot fit the necessary rail-fastening hardware.
Space Constraints: Interleaving four separate rails inside the same restricted width allows different trains to cross narrow infrastructure like bridges or tunnels without building entirely separate parallel spans.
Examples of Similar Infrastructure
Russia-North Korea Border: The crossing over the Tumen River utilizes multi-gauge configurations to accommodate Russian broad gauge and standard gauge connecting to the port of Rajin.
Historical and Industrial Lines: Short interlaced stretches have been historically deployed on restricted-width civil engineering structures like the Boyne Viaduct in Ireland during structural renewals, or on specific quarry tramways (such as the Ravenglass and Eskdale Railway in the UK) to temporarily interchange standard and narrow gauge wagons.
Centrica Energy And Zelestra Sign Battery Storage Tolling Agreement
The title of of this post, is the same as that as this press release from Centrica.
This is the sub-heading.
Centrica Energy and Zelestra have signed a physical tolling agreement for 99 MW / 297 MWh of battery storage capacity at Zelestra’s Hilgermissen BESS project, located in Lower Saxony, Germany.
These three paragraphs add some more details.
Under the agreement, Zelestra will develop, construct and own the battery storage project, building on their experience in delivering major projects in other markets and their extensive pipeline across Europe. Engineering and procurement activities will be completed this year leading to start of construction in 2027 and operations in 2028.
Under the tolling agreement, the battery will be optimised through Centrica Energy’s multi-market trading and optimisation services, enabling participation across Day-Ahead, Intraday and Ancillary Services in Germany.
Lower Saxony has a strong industrial base, from the automotive industry to agriculture and food production, as well as being a strong wind power and biomass energy producer. With a growing need for flexible capacity to support the stability and resilience of the power system, the BESS project will help accelerate renewable integration, strengthen grid flexibility and support Germany’s wider decarbonisation objectives.
In some ways, I find this press release a bit surprising.
Surely, a nation like Germany has the mathematicians, who are capable of doing this optimisation of a Battery Energy Storage System or BESS.
In New Optimisation Agreement For 70 MW / 160 MWh BESS In Sweden, I wrote about Centrica doing the same thing for the Swedes.
It strikes me, that somewhere in Centrica are one or more very bright mathematicians.
They have a web page, where they describe what they can do for your BESS.
I also believe, that underlying the management of the UK’s gas and the Grain LNG Terminal, which I talk about in Andy Burnham Set For Clash With MPs Over North Sea Oil And Gas, there is some very clever mathematics.
Offshore Wind Could Help Create ‘Electric Shipping Highway’ Across Europe, Study Says
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Offshore wind farms, energy islands, ports and proposed “Offshore Power Zones” could together form the foundation of an integrated maritime energy system capable of supporting large-scale vessel electrification across Northern Europe, according to a study by Maersk’s Stillstrom, Baltic Energy Island and the Port of Roenne.
This is a map from the report.
Note.
- In Investment in Grain LNG, I talked about Centrica and Grain LNG Terminal, Centrica’s plans for the terminal, which include bunkering.
- London Gateway and Immingham are two substantial ports on the East side of England.
Are English ports, except for the notable exception of Felixstowe, not shown on the map, because of Brexit?
These two paragraphs add some detail.
According to the findings, it is estimated that around 37,000 cargo vessels pass Bornholm each year, consuming approximately 3 million tonnes of marine fuel and emitting around 10 million tonnes of CO₂ annually. Full electrification of this traffic is estimated to require about 17 TWh of electricity per year, potentially replacing roughly EUR 2 billion in fossil fuel imports with domestically generated renewable power.
The whitepaper also introduces the concept of Offshore Power Zones (OPZs), developed by Stillstrom, which involves vessels accessing offshore wind-generated electricity at sea for battery charging or hotel loads. The report sees these zones linked with electrified ports to form an “electric shipping highway” stretching from the English Channel through the North Sea into the Baltic Sea.
Note that Bornholm is between Sweden and Germany.
New Optimisation Agreement For 70 MW / 160 MWh BESS In Sweden
The title of this post is the same as that of this press release from Centrica.
This is the sub-heading.
Centrica Energy, the energy trading and optimisation arm of Centrica plc, has signed an optimisation agreement with Ånge Storage Solutions AB, a project company jointly established by Delta Capacity, a Swiss-based developer of utility-scale battery storage systems, and Wood & Co., a leading European investment bank and asset manager, for a 70 MW / 160 MWh battery project in Ånge, Sweden, scheduled to be commissioned in Q2 2026.
These three paragraphs add more detail.
Once operational, the Ånge project will be the largest BESS currently in operation in the Nordics, underlining the strong partnership between the companies and the project’s clear strategic significance and market impact. The project represents a major step forward for grid flexibility in Sweden, supporting the country’s rapidly growing renewable energy capacity while strengthening system stability in the SE2 bidding zone.
Under the agreement, Centrica Energy will act as optimiser for the project, providing 24/7 in-house trading and optimisation services. Leveraging advanced forecasting, real-time market benchmarking and AI-enhanced trading algorithms, Centrica Energy will optimise the battery across wholesale electricity markets and ancillary services, dynamically capturing value across multiple revenue streams.
The agreement on the Ånge project kicks off the partnership between Centrica Energy and Delta Capacity, underlining the companies’ shared ambition to accelerate flexible energy solutions across the Nordics.
It seems that Centrica are doing some serious programming, which mirrors the offbeat engineering, that was hinted at in Centrica Tackles Difficult Terrain To Deliver Sustainable Solar Solution For Derbyshire Manufacturer.
You can’t do anything but like Centrica’s robust attitude and their determination to get things done.
I also wonder, if Centrica are putting their expertise and technical excellence alongside the money and risk of others!
You can argue it was like that with Artemis in the last thirty years of the last century. One quarter million pound computer and software package would be planning and controlling the building of a multi-billion pound project.
I feel now, that I can say that now the Channel Tunnel is part of my history.
From the words of the press release, they seem to have developed a very-sophisticated hybrid-battery-control system, where types with expertise-honed on the trading floor or even the battlefield, could be intimately involved in the decisions.
As a check on my use of battlefield, I asked Google AI”if ex military weapons officers good operators on a city trading floor?” and received this reply.
Ex-military weapons officers—and military officers more broadly—can make excellent operators on a city trading floor, as their skill sets in leadership, pressure management, and risk assessment are highly transferable and increasingly sought after by financial institutions.
Key Reasons Military Officers Succeed as Traders
Decision-Making Under Extreme Pressure: Operational officers are accustomed to making critical, split-second decisions with limited information, which mirrors the environment of a volatile trading floor.
Risk Management & Discipline: The military teaches meticulous planning, risk mitigation, and strict adherence to procedures. In trading, this translates into managing margin, controlling losses, and following a strict, repeatable trading strategy.
High Mental Stamina and Resilience: The ability to stay calm and focused when others are losing their composure is a key trait that veterans bring, helping them survive high-stress trading scenarios.
Adaptability: The ability to respond to changing circumstances on the battlefield translates into managing portfolios in rapidly shifting market conditions.
Transferable Skills Checklist
Strategy & Logistics: Background in understanding supply chain imbalances (supply/demand).Communication: Ability to convey orders clearly and concisely.
Integrity: High level of discipline and accountability.
Potential Challenges and Considerations
While they possess strong psychological skills for trading, ex-military personnel often face a steep learning curve regarding technical financial knowledge and specific market terminology. Furthermore, the transition from a highly structured hierarchy to a meritocracy—where the only measure of success is profit/loss—requires a change in mindset.
Industry Adoption
Banks and trading firms in both the UK and US have recognized the value of these skills, with firms like Citibank and various prop firms establishing veteran-focused programs to hire and train former military personnel.
Conclusion
If ex-military weapons officers can adapt their ability to assess risks and manage operations to financial data, their natural inclination to stay calm under pressure and operate with discipline makes them top candidates for trading roles.
SeaTwirl AB Signs Agreement To Explore Ehe Feasibility Of Electrification Of Aquaculture In Chile
The title of this post, is the same, as that of this press release from SeaTwirl.
This is the sub-heading.
SeaTwirl AB has entered into an agreement to carry out a feasibility study for electrification of fish farms together with a global industrial supplier. The intention of the collaboration is to assess the use of SeaTwirl’s floating vertical-axis wind turbines to provide renewable electricity to offshore-based equipment at aquaculture assets in Chile.
These three paragraphs add more details.
The feasibility study will cover a comprehensive scope, including energy demand and power system requirements, environmental site conditions, cost assessments, supply chain opportunities, and logistics in Chilean waters with the intention to reduce dependence on diesel. The study is expected to be completed during 2026, and the results will help determine next steps.
Chile is home to one of the largest aquaculture industries in the world, and the sector is pursuing ambitious sustainability goals including lower emissions, increased use of renewable power and reduced risk of spills. While the contractual value of the agreement is limited, at approximately SEK 0,8 million, the engagement will generate revenue and represent an important step in SeaTwirl’s commercialization effort.
“This collaboration marks an exciting step towards our purpose to enable floating wind power wherever it is needed, and to expand the use of floating wind technology beyond traditional grid-connected applications. The aquaculture industry has a clear need for offshore renewable energy, and we believe our technology can deliver a robust and cost-effective solution. It is also a major milestone to become involved in the southern hemisphere where many of the challenges we try to address, such as limited availability of cranes, vessels, and yard infrastructure, may be more challenging than in the north. We see significant potential in the aquaculture segment and look forward to beginning this journey in South America”, says Johan Sandberg, CEO of SeaTwirl.
I do find it strange, that the two vertical wind turbines, that both seem to be more than prototypes are both Scandinavian.
The Ventum Dynamics turbine, that I talked about in Are These Turbines An Alternative To Solar Panels? is Norwegian and this one is installed on Skegness Pier.
IKEA could sell these for DIY-enthusiasts to assemble and erect. On my stud, I used to have a barn, that could certainly have taken two of these 1.5 KW VX175 turbines.
This link is video of a dancing and swimming SeaTwirl.
If you follow, the SeaTwirl video to its conclusion, you’ll see one being erected in the sea. I can assure you that in the 1970s, my 25-year-old self, did the calculations for a reusable oil production platform called a Balaena, which erected on the same principle. So, I’m fairly certain, that SeaTwirls can be an alternative to traditional wind turbines.
Does Nuclear Power Not Sell Newspapers?
Five days ago, In Rolls-Royce SMR Advances To Final Stage In Swedish Nuclear Competition, I wrote about Rolls-Royce being one of two successful bids to advance to the ext stage to build Small Modular Reactors for Vatenfall in Sweden.
Since then, Rolls-Royce’s Swedish success has not featured in any newspaper in the UK, not even the Financial Times.
I can only assume, that good news stories about nuclear power, don’t sell newspapers.
Rolls-Royce SMR Advances To Final Stage In Swedish Nuclear Competition
The title of this post, is the same as that of this press release from Rolls-Royce.
This is the sub-heading.
Rolls-Royce SMR has been selected by Vattenfall as one of only two companies to reach the final stage in the process to identify Sweden’s nuclear technology partner.
These are the first two paragraphs, which add details.
After being shortlisted in 2024, Rolls-Royce SMR has progressed through a detailed assessment and will now work with Vattenfall through the final technology selection which could initially result in Rolls-Royce SMR delivering three SMRs.
This positive news is testament to Rolls-Royce SMR’s transformative approach to delivering proven nuclear technology in an innovative way through modularisation and builds on our successful selection in both the United Kingdom and Czech Republic.
Some other points from the press release.
- Sweden is initially looking to build three SMRs.
- Each SMR will supply 470MWe of clean low-carbon electricity.
- They are expected to have a lifetime of sixty years. Sizewell B was originally expected to have a lifetime of forty years, but appears to be being extended to sixty years, so I will accept Rolls-Royce’s expected lifetime.
- The first units will be at the Ringhals site on the Värö Peninsula, where there is an existing nuclear power station.
This Google Map shows the Ringhals site in relation to Gothenburg.
The site is marked by the red arrow.
On taking a closer look, it appears to be a site with expansion possibilities.
The British Media Don’t Seem Very Interested
It is now the 31st of August and the only paper to report the story has been the Financial Times.
Heart Aerospace Relocates Corporate Headquarters To Los Angeles, California
The title of this post, is the same as that of this news item from Heart Aerospace.
This is the sub-heading.
Hybrid-electric airplane manufacturer Heart Aerospace has announced the relocation of its corporate headquarters from Gothenburg, Sweden to Los Angeles, California. This strategic move aims to bolster the company’s product development in the United States, supporting the upcoming experimental flights of its Heart X1 prototype and the future Heart X2 prototype.
These two introductory paragraphs add ,ore detail.
Scheduled for its maiden flight in 2025, the X1 marks a major milestone in Heart’s innovation journey, setting the stage for X2.
“Our move to Los Angeles marks a new chapter in Heart Aerospace’s journey—one that prioritizes iterative development and deeper vertical integration,” said Anders Forslund, co-founder and CEO of Heart Aerospace. “For the X2, we’re developing key technologies like batteries, actuation systems, software, and hybrid-electric hardware in-house. This approach allows us to refine and enhance our systems continuously, just as we’ve done with the X1 prototype, which has seen extensive testing and major design updates since its initial rollout in 2024.”
In some ways, I find this move to California slightly sad, as I suspect most of those associated with the airliner, would have liked to see the development stay in Sweden.
This paragraph gives more details on the reasons for the move.
“We are deeply grateful to our team in Sweden for being part of this chapter of Heart’s journey, and for all the support we have received in Sweden,” said Anders Forslund. “However, as our customers, partners, and investors are increasingly based in the U.S, we see greater opportunity in focusing our resources here. By consolidating our operations in Los Angeles, we can accelerate development, strengthen collaboration, and better position Heart Aerospace for the future.”
They are not mentioned, but I do hope, Trump’s tariffs have nothing to do with it.
The Odd Sugary Snack May Be Good For You (But Lay Off Sugary Drinks)
The title of this post, is the same as that of this article in The Tunes.
I shall be discussing this research with my cardiologist. My relationship with him is as doctor/patient, researcher/lab-rat and just friends. I am also coeliac and very much feel that I need to take the odd sugary snack to keep my energy levels up. I also had a serious stroke at 64, thirteen years ago, due to atrial fibrillation.
Sweden and coeliac disease could be another complicating factor here, as Sweden went the wrong way to try to eliminate coeliac disease after WW2 and just created a lot more.
I found about this Swedish research in a peer-reviewed paper entitled Coeliac Disease: Can We Avert The Impending Epidemic In India? in the Indian Journal of Research Medicine.
A History Of Sugary Snacks And Drinks And Me
Growing up in London, after World War 2, I didn’t get much sugar, as it was rationed.
But I did put it in tea and coffee.
I never ate many cakes, except for some chocolate ones.
My habit of not eating cakes and proper puddings really annoyed my mother-in-law.
I was a sickly child and I didn’t really get better until I was found to be coeliac at 50.
I am fairly certain, that my consumption of sugary snacks has got more, as I’ve got older.
But because American drinks, sweets and snacks could use sugar made from wheat, I don’t touch any American sweetened products.
But I haven’t put on any weight, since I was fifty.
Thanks to the likes of Leon, Marks and Spencer and the cafe at Worksop station for excellent sugary gluten-free snacks to keep me going!
