Gluten-Free Egg Sandwiches From Boots
This morning, I had to pick up a prescription from Boots on Moorgate in London.
I use them, as they are by the 141 bus stop, that I can use to get home, so I pass their outlet regularly throughout the week.
After picking up my prescription, I looked at their small food counter. I was actually looking for milk, as I am out and nowhere on the West side of Moorgate sells small one pint bottles.
They didn’t have any, but they did have two flavours of gluten-free sandwiches; cheese and egg.
So I bought a pack of the egg sandwiches.
These pictures show the one, I have just eaten for lunch, with a beer and a banana.
Note.
- In the last picture, the Adnams 0.5 % Ghost Ship can, is marked with the gluten-free symbol.
- The only allergens noted on the sandwich packet are egg and mustard.
- The bread looks like it could be Genius, which is a brand of gluten-free bread, that I trust.
- The packaging can be recycled.
The sandwich was excellent, but then on past experience at the Tate Gallery and Blackburn Cathedral cafe, gluten-free egg sandwiches are a good combination of flavours.
So next time, I’m hungry, I’ll march into Boots.
Observing Trains At Stafford Station
I’m fairly certain, that I’ve only been to Stafford once in my life, in the past. That would be in 1968, when I went to English Electric in the town, when I was looking for a job on leaving Liverpool University.
In the end, my first job on leaving was at ICI in Runcorn.
As Stafford station, is on the West Coast Main Line, I’ve been through the station many times, on my way to Liverpool, Manchester, Preston, Scotland and other places in the North West of England.
I travelled North to Stafford in one of London Northwestern’s Class 350 trains, which definitely had ironing board seats. Some of these trains are being replaced with new Class 730 trains.
Stafford Station
This OpenRailwayMap shows the layout of platforms at the station.
Note.
- Platforms are numbered starting with Platform 1 in the East.
- There are five through tracks for passenger trains and a double-track goods loop.
- All tracks are electrified and bi-directional.
- The platforms are three hundred metres long, but I feel they could be lengthened to take the 400 metre long High Speed Two trains.
- The platforms are certainly long enough for pairs of 200 metre long High Speed Two trains, to split and join at the station.
These pictures show Stafford station.
Note.
- The station was built of concrete in the early 1960s.
- It has a unique feature, in that there is a waiting area above the tracks, so kids of all ages can watch the trains speed through.
- It has been improved several times in recent years.
- It is step-free with several lifts.
I feel, the station could be converted into a major High Speed Two hub station.
High Speed Two Services
This graphic shows High Speed Two services after Phase 2b is completed.
Note.
- Everything to the right of the vertical black line has now been cancelled
- Services shown in blue are run by High Speed Two Full Size trains.
- Services shown in yellow are run by High Speed Two Classic-Compatible trains.
- Each of these trains will have a frequency of one train per hour (tph).
These High Speed Two trains pass through Stafford.
- London and Lancaster/Liverpool Lime Street – Split/Join at Crewe
- London and Crewe/Runcorn/Liverpool Lime Street
- London and Stafford/Stoke-on-Trent/Macclesfield
- London and Manchester Airport/Piccadilly
- London and Manchester Airport/Piccadilly
- London and Manchester Airport/Piccadilly
- London and Edinburgh/Glasgow – Split/Join at Carlisle
- London and Edinburgh/Glasgow – Split/Join at Carlisle
- Birmingham and Edinburgh/Glasgow
- Birmingham and Manchester Airport/Piccadilly
- Birmingham and Manchester Airport/Piccadilly
In addition space will need to be found for these other services.
- Avanti – London and Chester/North Wales
- Avanti – London and Blackpool
- Freight – London and Liverpool/Manchester and Scotland
That gives a total of at least fourteen tph through Stafford station or one every 257 seconds.
Between Stafford and Crewe, with the completion of the flyover at Norton Bridge, there is effectively four tracks all the way, so this should give enough capacity to allow fourteen tph between Stafford and Crewe.
Between Stafford and Handsacre junction, where High Speed Two will join the Trent Valley Line about half the route is four-track with the rest being just two-track.
Will the two-track section be able to handle fourteen tph? I suspect it will, especially, as it is sandwiched between two four-track sections.
These are my thoughts about making the most of capacity through Stafford station.
Could Pairs Of High Speed Two Trains, Split And Join At Stafford?
Stafford station has 300 metre long platforms and pairs of High Speed Two Trains are 400 metres long.
Looking at maps and pictures of Stafford station, I suspect that lengthening the platforms at Stafford would be possible.
In the provisional High Speed Two service diagram, that I displayed earlier, these are two services.
- London and Crewe/Runcorn/Liverpool Lime Street
- London and Stafford/Stoke-on-Trent/Macclesfield
These could be run as a pair of trains between London and Stafford.
One advantage of running the two services as a pair, is that it would reduce the number of trains between Stafford and Handsacre junction by one, which might help the scheduling of trains through the double-track section, of the Trent Valley Line.
Fitting In The London and Chester/North Wales Services
Consider.
- These important services will soon be run by five-car Class 805 trains.
- The trains are diesel-electric.
- A pair would be 260 m long.
- There are ten trains per day (tpd) on the route.
The service has a few problems.
- It takes up a path between Crewe and Handsacre junction via Stafford, where train paths are at a premium.
- It is not zero-carbon.
- If London and Holyhead times were reduced, it would probably attract more passengers to the route.
As there are plenty of spare paths on High Speed Two, due to the cancellation of the Eastern leg, the easiest way to speed up the service would be to use High Speed Two between Handsacre junction and London.
200 metre long High Speed Two Classic-Compatible trains could be used, but this would need one of the following.
Electrification between Crewe and Holyhead. Although this was promised by the last government, I suspect the antis will stop it.
Partial electrification between Crewe and Holyhead. As Crewe and Holyhead is only 105.5 miles, I suspect a creditable scheme to use battery-electric trains could be developed. These trains could be useful in opening up High Speed Two to other destinations.
Could Other Services Piggy-Back On London and Chester/North Wales Services?
The London and Chester/North Wales services would all be run by 200 metre long High Speed Two trains.
There would be no reason, why on the London end of the journey, they could be paired with another High Speed Two train to and from another destination.
- They could split and join with a Blackpool service at Crewe.
- They could split and join with a Barrow service at Crewe.
- They could split and join with a second Stoke-on-Trent/Macclesfield service at Stafford.
Services like these, would improve the coverage of High Speed Two.
As with the joining of the Liverpool Lime Street and Macclesfield services, the pairing of trains reduces the number of paths needed on the double-track section of the Trent Valley Line to the South of Stafford.
Other Splitting And Joining At Stafford
It may be possible to arrange other splitting and joining at Stafford.
By rearranging the Manchester and/or the Scottish services, it might be possible to reduce the number of trains, through the double-track section of the Trent Valley Line.
There are certainly several possibilities.
Conclusion
Stafford station could be crucial, in making High Speed Two Lite feasible.
We Should All Raise A Glass To Sven
The BBC has a very matter-of-fact article on the death of Sven-Goran Eriksson, which is entitled Former England Manager Eriksson Dies Aged 76.
The article finishes with these words from Sven.
I hope you will remember me as a positive guy trying to do everything he could do.
“Don’t be sorry, smile. Thank you for everything, coaches, players, the crowds, it’s been fantastic. Take care of yourself and take care of your life. And live it.
There are no major fixtures today, but it will be interesting to see how he is remembered by fans, at the weekend!
SaxaVord ‘A Real Spaceport Now’ After First Rocket Explosion
The title of this post, is the same as that of the title of this article on The Times.
This is the sub-heading.
Despite the disappointment of last Monday’s fire engineers remain confident that the Unst site is ready for launch
These are the first two paragraphs.
Nothing could look more ominous for the European space industry than the tower of flame lighting up the skies over Shetland’s SaxaVord spaceport when a prototype engine suddenly and spectacularly caught fire on the launchpad last week.
The blaze was certainly “a nightmare” for the engineers of Rocket Factory Augsburg (RFA), the German company that hoped to conduct its first vertical rocket launch this year.
These are my thoughts and some from the article.
- I can remember a headline of Ike’s Phutnik, in a tabloid, when the United States tried to launch their first satellite.
- The safety systems seem to have worked well and no-one was hurt.
- The Chief Operating Officer of Rocket Factory Augsburg, still seems to have the ambition to make the project succeed.
- The operators are confident that SaxaVord will be ready for the next trials, whenever they are required.
- There is interest from Malaysia, to launch earth observation satellites.
- Scotland also offers other opportunities to southeast Asian tech businesses, as there are no launch sites in the region.
But most importantly, SaxaVord is generating interest from a wide range of users, as this paragraph indicates.
Others have already decided. SaxaVord has struck launch agreements with Lockheed Martin, the US aerospace giant and the German company HyImpulse as well as the UK’s Skyrora. Another four deals with international satellite companies are said to be in the offing.
If an established company were to launch a successful satellite, it could make all the difference to SaxaVord.
Conclusion
These are the last two paragraphs of the article.
Interest on this global scale enables the Scottish space pioneers to shrug off Monday’s blaze and the bad publicity it entailed. For anyone thinking the fire was bad news, emails from colleagues in the US told an altogether different story.
“You’re a real spaceport now,” read one message to a Shetland engineer. “You can’t call yourself a spaceport until you’ve had a rocket blow up!”
I have been to a party at NASA in Houston and they wouldn’t have been as successful, as they have, if they gave up on a failure. They try, try and try again.
Spotlight On The IVECO E-WAY H2: Less Weight, 15% More Passenger Capacity
The title of this post, is the same as that of this article on Sustainable Bus.
This is the sub-heading.
Up to seven time less batteries than a BEV bus (one module instead of 7), with 15% more passengers. These are the specifications mostly stressed by IVECO BUS when outlining the features of IVECO BUS E-WAY H2, presented at Busworld 2023 in Brussels. The bus model derives directly from the E-WAY BEV bus model
Note.
- The hydrogen fuel cell technology is from Hyundai.
- The bus is designed to be lighter in weight, which increases passenger capacity from 93 to 111 and gives an enhanced range.
- The driveline is from Accelera by Cummins, with a Siemens electric motor.
- IVECO provide the front axle and ZF the rear.
- Surprisingly, the bus is assembled from stainless steel panels, onto a steel floor.
It strikes me, that if the late great Colin Chapman had designed a bus, it would follow some of IVECO’s design.
Conclusion
This bus could set the standard for hydrogen-powered buses.
I particularly liked the saving in lithium compared to an electric bus.
Global Offshore Wind To Top 520 GW By 2040, Floating Wind To Play Major Role – Rystad Energy
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
According to Rystad Energy, global offshore wind capacity will surpass 520 GW by 2040, with floating wind installations nearing 90 GW by that time
These are the first three paragraphs.
In 2023, the offshore wind sector saw a seven per cent increase in new capacity additions compared to the previous year, said Rystad Energy. This momentum is expected to accelerate this year, with new capacity additions expected to grow by nine per cent to over 11 GW by the end of the year.
By 2040, Europe is expected to account for more than 70 per cent of global floating wind installations. Although some project delays beyond 2030 are anticipated, there will likely be a strong push to accelerate deployment, according to Rystad Energy.
As a result, floating wind capacity is projected to approach 90 GW by 2040, led by the UK, France, and Portugal, with Asia (excluding mainland China) expected to account for 20 per cent of global installations.
Note, that Rystad Energy is an independent energy research and business intelligence company headquartered in Oslo, Norway.
Implications For Energy Storage
In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I talk about how the 2.9 GW Hornsea Three wind farm will have a connection to the grid, that incorporates a 300 MW/600 MWh battery.
With 520 GW of offshore wind to be installed by 2040, I suspect that energy storage companies and funds will do well.
If the 520 GW of offshore wind were fitted with batteries like the 2.9 GW Hornsea Three wind farm, there would be a need for around 60 GW of battery output, with a capacity of around 120 GWh.
I doubt, there would be enough lithium for all those batteries.
Some countries like Norway, the United States, Australia, France, Spain, Japan, India, China and others will be able to develop large pumped storage hydroelectricity systems, but others will have to rely on newer, developing technologies.
The UK will be well-placed with around 80 GWh of pumped storage hydroelectricity under development and several promising developing storage technologies.
Was I One Of The First To Have My Temperature Measured By A Thermometer Reading The Radiation From My Ear?
Last week, a doctor read my body temperature, by using an electronic thermometer, that read the temperature inside my ear.
But it wasn’t the first time!
That must have been in 1968 or 1969, when I was working at ICI in Runcorn.
ICI had a problem, in that they needed to read the temperature of chemical reaction vessels.
- Temperatures could be higher, than 1,000 °C.
- Some mixtures could be highly corrosive.
- Safety needed to be as high as possible.
My colleague; John Baxendale was assigned the problem.
John came up with a solution based on black bodies and their unique black body radiation.
These two paragraphs, from the Wikipedia entry for black body, explain the principle.
A black body or is an idealised physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The radiation emitted by a black body in thermal equilibrium with its environment is called black-body radiation. The name “black body” is given because it absorbs all colours of light. In contrast, a white body is one with a “rough surface that reflects all incident rays completely and uniformly in all directions.”
A black body in thermal equilibrium (that is, at a constant temperature) emits electromagnetic black-body radiation. The radiation is emitted according to Planck’s law, meaning that it has a spectrum that is determined by the temperature alone, not by the body’s shape or composition.
Note, that I have very mildly edited, what Wikipedia says, to the King’s English.
John had developed some clever electronics, that read the spectrum of the radiation and by decoding the spectrum, he was able to calculate the temperature.
Early on in the testing, John found that nearly all of us, have two black bodies on the side of our heads; our ears, so he could measure the temperature inside them.
City Airport May Help Others To Take Flight
The title of this post, is the same as that of this article on The Times.
This is the sub-heading.
The government’s decision to lift the cap on permitted passengers at London City airport is a compromise that could be a template for future growth
These are the first two paragraphs.
Planning decisions always upset someone. Still, credit to housing secretary Angela Rayner and the transport supremo Louise Haigh for annoying all sides with one of the first from the new Labour government: allowing London City airport to lift its cap on permitted passengers a year to nine million from the present 6.5 million.
Their verdict hacked off Newham council, which has long opposed the airport’s expansion, leaving it “deeply concerned” over the noise impact on local residents. It angered environmental campaigners, with Greenpeace saying it’d “undermine the UK’s climate leadership”. And it even “disappointed” the airport’s boss, Alison FitzGerald, who wanted an end to the 24-hour flight curfew from 12.30pm on Saturday but failed to get it pushed out to 6.30pm.
The government seem to have chosen a good compromise that has annoyed several parties.
The article goes on to argue, that we should make the best use of the thirty regional airports in the UK.
So shouldn’t the priority be to utilise regional capacity better, via airline and airport incentives if necessary, to minimise journey times to airports and spread the noise and air pollution around? Only then should ministers consider big new projects.
That seems very sensible to me.
Consider.
- Technology will bring us quieter and more environmentally-friendly aircraft, that will benefit those near the airport.
- Electric aircraft are closer to service entry than you think.
- Good public transport links to an airport, would surely cut car usage for both passengers and employees.
- Bus networks to many airports could be improved and made more attractive to passengers, by using modern electric or hydrogen buses. Even Gatwick is taking this route!
- Cranbrook station and Exeter Airport were supposed to have a bus link, but nothing has happened.
- Several airports are near main railway lines and it would be possible to build a station. It will be interesting to see how passenger traffic at the new Inverness station develops.
- East Midlands, Edinburgh, Glasgow, Leeds/Bradford and Liverpool Airports are larger regional airports, that are close, but not directly connected to the rail network.
- Carlisle and Exeter Airports don’t have the best of websites. Humberside sets a good standard.
- Doncaster Sheffield Airport has everything except a rail link and scheduled services.
Some of these improvements are not major and would surely be worthwhile, especially with a small amount of compromise.
Funding Awarded For Study On Hydrogen Storage Potential In The East Midlands
The title of this post, is the same as that of this article on the British Geological Survey.
This is the sub-heading.
A new study has been awarded funding to explore the underground hydrogen storage potential in the East Midlands.
These are the first three paragraphs.
East Midlands Storage (EMstor), a consortium led by Cadent and partnered with BGS, Star Energy Group, Net Zero Strategy and the University of Edinburgh, has been awarded discovery funding by Ofgem’s Strategic Innovation Fund to undertake a new study to evaluate geological storage potential in the East Midlands.
The EMstor study is the first of its kind in the region. It will undertake a feasibility assessment of the East Midlands’ geology to evaluate its potential to host storage technologies, allowing expansion of Cadent’s proposed 100 per cent hydrogen pipeline.
The East Midlands has numerous depleted oil reservoirs, which may have potential to store hydrogen. The study will characterise the potential geological reservoir to establish if it is suitable for hydrogen storage at scale in the local area.
The oilfields of the East Midlands Oil Province have their own Wikipedia entry, which gives full details of the dozens of small oil fields in the area.
- It may not be the world’s largest oil resource, but it certainly helped us during the Second World War.
- Experienced Texan oil-men were even imported, to help boost production.
- It used to be possible to spot the occasional lonely nodding donkey, as you passed through the area.
Surely, if some of the oilfields can be converted to hydrogen stores, this would be very useful.
London And Edinburgh By Lumo Using the Joint Line Diversion
This press release on the First Group web site is entitled FirstGroup Applies To Run Rochdale To London Rail Service With New British-Built Trains.
These are the first two paragraphs.
FirstGroup plc, the leading private sector transport operator, has submitted the first phase of an application for a new open access rail service between Rochdale and London to the Office of Rail and Road (ORR), restoring this direct link for the first time in almost a quarter of a century.
FirstGroup plans to expand its open access rail operations as part of its successful Lumo business, building on Lumo’s existing service which has transformed long-distance connectivity between London and Edinburgh and helped support a growth in passenger numbers for all operators on the East Coast Mainline. All of the trains on this new route will be electric and battery powered, and the service will be operated by brand new trains built in the UK.
Note.
- This service will be run under the Lumo brand.
- Battery-electric trains will be used.
- Stops will include Manchester Victoria, Eccles, Newton-le-Willows and Warrington Bank Quay.
- Only 15 km. of the route, between Miles Platting and Rochdale is not electrified.
Allowing for out and back trips between Platting and Rochdale, a sensible reserve and I suspect a battery-electric train with a range of 40-50 kilometres, would allow the train to be able to do a round trip to Rochdale from London Euston.
Hitachi have now published this page on their web site, which is entitled Intercity Battery Trains.
These are the first two paragraphs.
A quick and easy application of battery technology is to install it on existing or future Hitachi intercity trains. Hitachi Rail’s modular design means this can be done without the need to re-engineer or rebuild the train and return them to service as quickly as possible for passengers.
Replacing one diesel engine with just one battery reduces emissions by more than 20% and offers cost savings of 20-30%. Our intercity battery powered trains can cover 70km on non-electrified routes, operating at intercity speeds at the same or increased performance.
It would appear that Hitachi’s standard Intercity Battery Train will have a range of 70 km.
- A 70 km. range would be more than enough to handle Lumo’s Euston and Rochdale service.
- Lumo’s Class 803 trains don’t have a diesel generator to replace.
- One car does have a smaller battery for emergency hotel power, should the electrification fail.
As an Electrical Engineer, I wouldn’t be surprised to find out that the traction batteries of Hitachi’s standard Intercity Battery Train and the emergency batteries of Lumo’s Class 803 trains are of a similar design. The batteries could even be interchangeable, which would enable both Lumo’s routes to Scotland and Rochdale to use identical Class 803 trains.
Lumo’s Class 803 trains would have this specification.
- All-electric.
- Emergency battery to provide back-up hotel power.
- A range on battery of 70 km or 43 miles away from electrification.
The off-electrification range could be very useful in getting round incidents or overhead wiring problems.
An extended range of 70 km. would allow the following destinations to have all-electric services from London.
- Beverley #
- Bristol Temple Meads #
- Cheltenham #
- Chester
- Harrogate
- Huddersfield
- Hull
- Lincoln
- Middlesbrough
- Swansea #
Destinations marked with a hash (#), would need charging at the final destination.
A more detailed analysis will probably show other possible routes.
It looks to me, that Hitachi have got the specification of their Intercity Battery Train about right.
Bridging The Joint Line Diversion
This OpenRailwayMap shows the Great Northern and Great Eastern Joint Line (GNGE) or Joint Line.
Note.
- Doncaster is in the North-West corner of the map.
- Peterborough is in the South-East corner of the map.
- The red line connecting them is the East Coast Main Line.
- Lincoln station is marked by the blue arrow.
Great Northern and Great Eastern Joint Line (GNGE) is described like this by its Wikipedia entry.
The Great Northern and Great Eastern Joint Railway, colloquially referred to as “the Joint Line” was a railway line connecting Doncaster and Lincoln with March and Huntingdon in the eastern counties of England. It was owned jointly by the Great Northern Railway (GNR) and the Great Eastern Railway (GER).
Over the last decades of the Twentieth Century, the Joint Line declined and British Rail did their worst to simplify the route.
But in the 2010s, Network Rail developed the route into a by-pass for the East Coast Main Line between Werrington and Black Carr junctions via Lincoln.
- Trains are routed via Spalding, Sleaford, Lincoln, Saxilby and Gainsborough.
- There is no electrification.
- The route can handle two freight trains per hour.
- The route can handle 9 ft. 6 in containers.
- There is a passenger service between Doncaster and Peterborough via Lincoln.
- Self-powered trains like InterCity125s, Class 800 trains and Class 802 trains can use their diesel power to use the diversion.
- All-electric trains, like LNER’s Class 801 trains and Lumo’s Class 803 trains have no self-power, so can’t use the diversion.
- Black Carr junction and Lincoln is 35 miles.
- Werrington junction and Lincoln is 51.7 miles.
The January 2024 Edition of Modern Railways says that the diversion is approximately 90 miles or 145 kilometers.
It would appear that there are two simple solutions.
- Electrify a section through Lincoln, so that Lincoln is within 70 kilometres of the electrification at both Werrington and Black Carr junctions.
- Fit bigger batteries to the trains.
A combination of both solutions might be possible.
