Electric Freight: A Solution To The WCML Capacity Conundrum
The title of this post is the same as that of this article on Rail Engineer.
These two paragraphs introduce the article.
Network Rail considers the West Coast Main Line (WCML) to be the busiest mixed traffic railway in Europe. It carries 125mph passenger trains from London to the West Midlands, North West, and Scotland and is used by 90% of intermodal UK rail freight which has a maximum speed of 75mph. Traffic on the line has been steadily increasing. In 1994 there were seven daily passenger trains from Glasgow to London. Now there are 26.
In 2006 Network Rail commissioned an in-depth study to find the best way of providing additional capacity as, with increasing traffic, the WCML between London and the North West was forecast to be full by 2020. The study found that the provision of a new high-speed line was the best solution and was the basis for the development of the HS2 project. The 2006 study correctly forecast that the WCML will by now be at full capacity south of Crewe, yet following the curtailment of HS2 two years ago there are no proposals to address the capacity issue between Rugby and Crewe that was identified 20 years ago.
David Shirres, puts forward a solution that involves electric freight locomotives and faster freight wagons.
I can add some knowledge of what British Rail were doing in the 1970s to solve the problem of freight on the West Coast Main Line all those years ago.
This picture shows a PACE 231R.

In the early 1970s, I was lucky enough to work with one of these amazing machines. They were probably one of the most powerful analogue computers ever built, that could solve a hundred simultaneous differential equations at once using thermionic valve circuitry. Their most famous application was at NASA, where two of these machines formed the analogue half of the moon-landing simulator.
There were a handful of these powerful beasts in the UK at ICI Plastics, where I worked, British Motor Corporation, Cambridge University and British Rail Research at Derby.
At the time, British Rail were trying to run freight trains faster and the four-wheel freight wagons of the time were derailing with an unwanted regularity. So the problem was given to British Rail Research and the problem was put on the PACE 231R. The problem was solved and the lessons learned were applied to the Mark 3 Coach and the InterCity 125.
After privatisation, the research went to the National Railway Museum and out of curiosity a few years ago, I tried to look at it, but was told it was commercially sensitive to Bombardier. It is my belief, that if this research were to be continued at one of our best universities, that faster freight bogies could be developed, that would help to create the extra freight paths needed on the WCML.
Life-Saving Baby Incubators Uused In Ukraine Pass The NHS Test
The title of this post, is the same as that of this article from The Times.
This is the sub-heading.
The devices made by Mom Incubators weigh a fraction of existing models, making them highly mobile and perfect to use on maternity wards.
The incubator was developed as a final year student project.
- James Roberts founded Mom Incubators in 2014.
- Backers include Sir James Dyson and Holly Branson.
- The incubators have been used in England, Haiti, India, Kenya, the Philippines, Scotland, Uganda, Ukraine, US and Tanzania.
- This is a really wonderful story, which shows the value of good design and keeping the weight down.
James Roberts intends to repeat the excercise with other medical devices.
Hydrogen In Aviation Offers Potential For Growth And Deeper Emissions Reductions, New Study Shows
The title of this post, is the same as that of this press release from Rolls-Royce.
These five paragraphs compose the press release.
Rolls-Royce, easyJet, Heathrow and University College London Air Transportation Systems Lab (UCL ATSLab) published a report highlighting how hydrogen-powered aircraft could enable European and UK aviation to cut carbon emissions while supporting future growth.
The study, Enabling Hydrogen in the European Aviation Market, found that hydrogen in aviation offers a unique opportunity to achieve both emissions reduction and market expansion. The analysis shows that introducing hydrogen alongside Sustainable Aviation Fuel (SAF) can accelerate progress towards net zero, particularly when policy incentives reward low-carbon fuels and if hydrogen were to be included within the EU’s SAF mandate.
The research also found that targeted hydrogen infrastructure at around 20 major European airports, including Heathrow, could deliver more than 80% of the emissions benefits of full hydrogen availability across the continent. Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.
Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions, underscoring the value of early technological transition where it is financially and technically viable.
The study is underpinned by UCL ATSLab’s Airline Behaviour Model (ABM), which represents the complexity of airline decision-making through specific behavioural variables. Building on this, the research evaluates how fuel costs, incentives and new technologies shape airline responses. This provides a research-based, realistic picture of how hydrogen adoption could evolve, highlighting both opportunities and potential challenges for adoption.
Note, these two sentences recommending early adoption of hydrogen.
- Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.
- Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions.
I also suspect, that introducing hydrogen early, feeds back to reduce Co2 emissions.
But what is Trump’s considered view on hydrogen aircraft?
Google AI gives this answer to my question.
Donald Trump’s view on hydrogen for transportation, including potential use in aircraft, is highly skeptical due to perceived safety risks and effectiveness concerns, which generally aligns with his broader opposition to green energy initiatives. He has specifically criticized hydrogen-powered vehicles as being dangerous and “prone to blowing up”.
Note.
- I used to work in a hydrogen factory and it’s still producing hydrogen.
- I doubt Trump gets on well with Jennifer Rumsey, who is CEO of Cummins, who are one of the world’s largest diesel-engine companies, who are following a zero-carbon route.
- Is Formula One Likely To Go To Hydrogen Fuel? This would set the Cat Among The Pigeons
I also feel that this University College London study will create a string of converts to hydrogen.
US Interior Secretary: ‘No Future For Offshore Wind Under This Administration’
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
US Interior Secretary Doug Burgum said at a press conference on 10 September that offshore wind has no future in the US under the Trump administration and that the government was reviewing five offshore wind projects that are now under construction.
There is also this quote from Burgum.
Offshore wind was too expensive and not reliable enough.
Many of those projects weren’t really about electricity, they were about tax subsidies
I think the fact that the subsidies have been either cut back or limited means that it is likely that there will not be future offshore wind built in America.
He also added that there were concerns that wind turbines interfered with whales and radar systems.
I asked Google AI a few questions.
Is Offshore Wind Extremely Expensive?
Google AI replied.
No, offshore wind is not considered extremely expensive when compared to other energy sources, particularly gas-fired power stations, and its costs are projected to fall further. While initially more expensive to construct than onshore wind due to the marine environment, the higher and more consistent wind speeds offshore generate more power, leading to a competitive or lower overall levelised cost of energy (LCOE) in many regions. Recent economic challenges like inflation and supply chain disruptions have increased costs temporarily, but the sector’s financial position is recovering, and cost reductions are expected to continue.
That looks pretty fair to me.
Is Offshore Wind Reliable?
Google AI replied.
Yes, offshore wind is a reliable energy source because it generates power more consistently than onshore wind due to higher, more dependable wind speeds at sea, and can be integrated with other renewables and energy storage to provide continuous power. Offshore wind turbines operate almost all the time, and the power can be backed up by grid-level storage to ensure a steady electricity supply, even when the wind isn’t blowing.
That looks pretty fair to me.
Are Subsididies And Tax Breaks Important For Offshore Wind?
Google AI replied.
Yes, subsidies and tax breaks are important for the offshore wind industry, which faces high upfront costs and inflationary pressures, to make it more cost-competitive with fossil fuels and secure financing for projects. These incentives help reduce costs for developers, de-risk investments, and ensure the technology can meet climate targets by fostering investment and ensuring long-term viability.
That looks pretty fair to me, but if you were in the oil and gas industry you might think differently.
On the other hand some countries like Norway and the UK, are encouraging the linking of offshore wind farms to offshore oil and gas production to decarbonise offshore operations.
Does Offshore Wind Kill Whales?
This article on the BBC is entitled Fact-Checking Donald Trump’s Claim That Wind Turbines Kill Whales.
It goes into detail about Trump’s claims about wind turbines and marine life.
These are four paragraphs.
“We know what the main threats are to humpback whales: it’s very much the impact from things like fishing and ship strikes,” says Rob Deaville from the Zoological Society of London’s Cetacean Strandings Investigation Programme.
“To talk about wind farms being a problem takes away discussion around the very real threats that are a problem for those species.”
Many other areas with high numbers of wind farms have not seen an increase in whale mortality.
For example, the UK is home to the world’s four largest wind farms, but no humpback whale strandings there have been conclusively linked to the impact of those farms.
That looks pretty fair to me.
But because of our massive portfolio of offshore wind farms and top universities, who research the marine environment, the UK is in a unique position to expose fake science, that was made up on the back of a used envelope.
Does Offshore Interfere With Radar?
Google AI replied.
Yes, offshore wind farms can interfere with radar by reflecting radar signals, causing “radar clutter” or false echoes that can obscure real targets, like aircraft or ships, or create phantom images on a radar display. This interference, also known as a “blade flash,” can negatively impact air defense, air traffic control, and maritime navigation, leading to reduced accuracy and potential safety risks.
That looks pretty fair to me.
Have Wind Turbines Caused Any Air Accidents?
Google AI replied.
Yes, wind farms have caused air accidents, though they are rare. These incidents primarily involve light aircraft colliding with wind turbines or experiencing loss of control due to turbulence from turbine wakes. Examples include a pilot crashing near a wind farm due to turbulence and another fatal crash involving an aircraft hitting a turbine blade.
That looks pretty fair to me.
I learned to fly light aircraft in the 1970s and I remember being told about wake turbulence from airliners, which has been strong enough in some cases to flip an aircraft like a Cessna 150 upside down or into a spin.
What Are The CAA’s Rules For Flying Near Wind Turbines?
Google AI replied.
The primary CAA rule for flying near wind turbines is related to their visibility and safety, focusing on lighting requirements and potential hazards like turbulence. Structures 150 meters or higher require medium-intensity red lights. Pilots must avoid dazzling lights with their own, and wind turbine developers must assess and mitigate risks such as turbulence, radar interference, and impact on Instrument Flight Procedures (IFPs).
That looks like what I would have expected.
Conclusion
I have tried not to be selective with my evidence, but if you are there are reasons that could be used to ban wind turbines.
I am also happy to add any other questions.
I See My First Driverless Car
The pictures show the first driverless car, that I’ve seen.
It was happily going along the Balls Pond Road, where it stopped immaculately at the lights, at the junction with Southgate Road.
Recently, a pedestrian was killed at those lights by a truck. It looks like he didn’t understand the sequence of the lights and stepped out, when he shouldn’t.
As a Control Engineer, I have a feeling, that driverless cars will never live up to the hype.
Singapore’s First Hydrogen-Powered Data Center Launched By DayOne Using SOFC Technology
The title of this post, is the same as that of this article on Fuel Cell Works.
These two bullet points act as sub-headings.
- DayOne has broken ground on its first AI-ready hyperscale data center in Singapore, a 20MW facility set to be operational in 2026. The project integrates 100% renewable energy, SOFC-based hydrogen power generation, and cutting-edge hybrid cooling technologies.
- Strategic partnerships with Sembcorp and NUS will drive green energy adoption and R&D in sustainable tropical data center innovation, aligning with Singapore’s AI and digital infrastructure goals.
This data centre and the companies and the technologies behind it, are certainly ones to watch.
The R & D and innovation behind it could allow data centres to be built in more tropical places than is currently possible.
Are Zero- And Low-Alcohol Beers Cutting Road Accidents?
In The Times today, there is an article, which is entitled Drink-Driving ‘Effectively Legalised’ As Number Of Breath Tests Falls, where these are the first three paragraphs.
Drink-driving has effectively been legalised due to plummeting rates of breathalyser tests and light punishments for offenders, campaigners have warned.
The number of breath tests conducted by police has fallen by more than 62 per cent over the past decade as dangerously inebriated drivers receive short bans.
In 2009, police carried out 647,380 breath tests, but by 2023, that figure had fallen to just 240,322.
This later paragraph, adds a few more statistics.
In 2002, 18 per cent of breath tests were positive, compared to 16 per cent in 2023, while the number of drivers prosecuted for drink-driving offences has significantly decreased. Convictions for drink-driving fell from 55,300 in 2012 to 40,292 in 2023, coinciding with the sharp decline in breath testing.
Note, that in both extracts the latest comparison date is 2023, whereas the earliest date is 2009 and 2002.
This analysis is not the full picture, as there are two big differences between drinking in 2002 or 2009 and 2023.
The first difference is that 2002 and 2009 are pre-Covid, but 2023 is post-Covid.
So did Covid alter our drinking habits, which could have perhaps meant more people drank at home?
The second difference is that in 2023, zero and low alcohol beer was readily available.
I don’t drive, after a stroke ruined my eyesight, but I do drink up to four bottles a day of 0.5 % real ale. The beer I drink has been regularly available since 2017.
I wonder how many nominated drivers are now drinking these beers?
A serious survey and analysis needs to be done.
AI Forecast To Fuel Doubling In Data Centre Electricity Demand By 2030
The title of this post, is the same as that as this article in The Times.
This is the sub-heading.
International Energy Agency predicts that artificial intelligence could help reduce total greenhouse gas emissions
These are the first two paragraphs.
Data centres will use more than twice as much electricity by 2030 than they do today as artificial intelligence drives demand, the International Energy Agency predicts.
The agency forecast that all data centres globally will use about 945 terawatt-hours of electricity each year by 2030, roughly three times as much as the UK’s total annual demand of 317 terawatt-hours in 2023.
I am very much an optimist, that here in the UK, we will be able to satisfy demand for the generation and distribution of electricity.
- Our seas can accommodate enough wind turbines to provide the baseload of electricity we will need.
- Roofs and fields will be covered in solar panels.
- SSE seem to be getting their act together with pumped storage hydro in Scotland.
- I am confident, that new energy storage technologies like Highview Power with the packing of companies like Centrica, Goldman Sachs, Rio Tinto and others will come good, in providing power, when the wind doesn’t blow and the sun doesn’t shine.
- Hopefully, Hinckley Point C and Sizewell C will be online and soon to be joined by the first of the new small modular nuclear reactors.
- Hopefully, Mersey Tidal Power will be operating.
- There will be innovative ideas like heata from Centrica’s research. The economical water heater even made BBC’s One Show last week.
The only problem will be the Nimbies.
Tea Removes Toxic Heavy Metals From Water, Study Suggests
The title of this post, is the same as that of this article on The Times.
This is the sub-heading.
The longer tea is steeped, the more contaminants are removed
These are the first three paragraphs, which give a flavour of the research.
A daily cup of tea may do more than just perk you up — it can also purge the water of toxic heavy metals, a study suggests.
Researchers found that tea leaves will trap lead, cadmium, and other unwanted contaminants during the brewing process. These metals bind to the leaves and remain there until they are thrown away.
Benjamin Shindel of Northwestern University, Illinois, who led the research, said that while other materials might achieve a similar effect, tea’s popularity made it unique. “What is special about tea is that it’s the most consumed beverage in the world,” he explained.
My late wife was a coffee drinker and I only have the odd cup of cappuccino, although, I do drink lots of zero-alcohol beer, hot chocolate and decaffeinated tea.
I would assume that from his name Professor Benjamin Shindel is quite likely to be Jewish.
So did he ask all his friends and relatives round for a tea party?
The Professor certainly wouldn’t have had to have stinted on the cakes, as they wouldn’t have got near the water, which was the real subject of the research.
But he wouldn’t have been short of volunteers to brew their favourite tea!
