Net-Zero Concept Aircraft: Which Designs Are The Current Front Runners?
The title of this post is the same as that of this article on Simple Flying.
The article is a good summary of what may happen in the field of Net-Zero aircraft in the next ten or twelve years.
Old Street Station – 2nd May 2023
I took these pictures this morning, as my bus passed Old Street roundabout.
It’s still progressing as slowly as ever.
Nicholas Lane – 1st May 2023
Nicholas Lane is a lane in the City of London, that runs between Cannon Street in the South and Lombard Street in the North.
This Google Map shows the lane.
Note.
- Nicholas Lane tuns diagonally across King William Street.
- Cannon Street can be seen in the South-West corner of the map.
- The new entrance to Bank station is on Cannon Street.
- Nicholas Lane runs up the side of the new station entrance.
- There are two bus stops for the 21, 43 and 141 buses on King William Street.
The bus stops are within easy walking distance of the new station entrance, if you walk along the Southern section of Nicholas Lane.
These pictures show Nicholas Lane and King William Street.
Note.
- I suspect some coffee shops or a fast food joint will appear at the King William Street end of Nicholas Lane.
- The windows on the corner could be ready to be a shop.
- In Bank Station Upgrade – 6th January 2023, I described the eight storey building, that will sit on top of the station entrance.
The lane could also a preferred route for many, who are changing at Bank station to or from the buses.
Elizabeth Line Takes Fliers Away From Heathrow Express
The title of this post, is the same as that of this article on The Times.
These three paragraphs add details to the story.
The opening of the Elizabeth Line has eaten into the revenues of Heathrow Express, the country’s most expensive railway service per mile travelled.
Filings reveal that Heathrow Express, which offers a 15-minute service between London Paddington and Heathrow, has failed to recover to pre-pandemic levels despite flight volumes at the airport returning to near-normal. Heathrow said revenues from Heathrow Express in the first three months of the year were £22 million.
While that is 50 per cent more than in the same period last year, when Covid-19 travel restrictions were beginning to be relaxed, it is almost a third down on the £31 million of revenues in the first quarter of 2019.
Considering how air travel is on the upturn, Heathrow Express would not appear to be performing as the airport expects.
Remember, that First Group are paid by Heathrow Airport to run the service, which is owned by the airport.
In So Many Cases On A Train!, I wrote about a trip from West Ealing to Moorgate station. These were my opening sentences.
This afternoon about three, I went to West Ealing station to see what it was like to transfer between the Elizabeth Line Central Tunnel and the Western Branch at Paddington.
Coming back, I took an Elizabeth Line service that had started from Heathrow Airport and it was one of the busiest Lizzies, I’d ever ridden!
To get on the train at West Ealing station, I got in to probably coach 4 of 9, as that was in the dry and the back end of the train I needed for Moorgate station was certainly in the wet.
I then had to walk half the length of the train to get to the back of the train.
It was not easy, as the train was full of scores of passengers with large wheelie cases.
It certainly got me thinking about how passengers were getting to and from Heathrow and I came to this conclusion.
Lizzie will start a revolution in travel to and from Heathrow.
Judging by the title of the article in The Times, the revolution has already started.
Consider these reasons.
- Heathrow Express is overpriced.
- It doesn’t go where many passengers want to go.
- It’s not the best way to get workers to and from the airport.
- The ULEZ will discourage passengers and staff from driving to the airport.
In Effects Of The ULEZ In West London, I said this about journeys to and from the airport.
Heathrow Airport is one of the world’s busiest airports and 76,000 people work at the airport, with many more employed nearby.
The airport handled 61.6 million passengers in 2022, which is a few short of 170,000 per day.
If you consider that those that work at the airport do two trips per day and passengers generally do one, that means there are 322,000 trips per day to or from the airport.
But as it now so easy to get to the Airport using the Elizabeth Line will more people use the new line to meet and greet and say goodbye to loved ones or business associates. Since the Elizabeth Line opened, I’ve met a couple of friends at Heathrow, who were passing through.
I wonder, if that daily journey total of 322,000 could be nearer to 350,000 or even 400,000.
If the ULEZ charge makes some passengers and staff switch from their car to using a bus or train, this probably means that public transport to and from the airport, will need to be boosted by a substantial amount.
I can see airport workers lobbying for free tickets on Heathrow Express, but they probably live closer to the airport than Paddington or perhaps even in the Eastern areas of London served by the Elizabeth Line.
The Elizabeth Line Is Showing Signs Of Running Out Of Capacity
In the last few weeks, I’ve been on some very full Elizabeth Line trains.
Articles, like this one on Rail Advent, which is entitled Transport for London Looks Into Funding For Additional Elizabeth Line Trains, are also starting to appear.
These three paragraphs explain the problem.
Transport for London has announced that they are looking for confirmation from the Government regarding funding so that they can look into the possibility of purchasing additional Elizabeth Line trains.
The news from TfL comes after the recent announcement of delays to HS2 terminating at London Euston.
TfL says that without the extra trains, there is insufficient capacity on the Elizabeth Line (until HS2 is extended to Euston in the 2040s) for passengers looking to use HS2 and the Elizabeth Line to get into Central London.
Alstom also appear to want the space in the factory to build other trains.
So it appears that Transport for London must act soon.
Heathrow Express Needs To Be Repurposed
In Extending The Elizabeth Line – High Speed Trains On The Elizabeth Line, I talked about running faster trains through the Central Tunnel of the Elizabeth Line.
As any train would have to be compatible with the platform-edge doors in the central tunnel of the Elizabeth Line, the trains would have to be dimensionally identical to the current Class 345 trains.
- Nine cars
- Possibility of lengthening to ten cars.
- 204.73 metres long.
- 6 sets of doors per carriage
- Ability to run under full digital signalling.
- The trains would be designed for a higher speed of at least 110 or 125 mph, to enable running on the fast lines of the Great Western Main Line.
- The trains would have Heathrow Express branding and interior.
Services could be as follows.
- Heathrow Terminal 4 and Southend Victoria via Bond Street and Liverpool Street for the City and Stratford.
- Heathrow Terminal 5 and Ebbsfleet International via Bond Street and Liverpool Street for the City and Canary Wharf.
Note.
- Both services would be two trains per hour (tph)
- Traffic would determine, which Eastern terminal is paired with which Western terminal.
- Each route would also have two Elizabeth Line tph on the same route.
The Heathrow Express services would run as follows.
- Between Heathrow Airport and Paddington, they would run as now.
- I believe that by using the power of the digital signalling, they could be slotted into the queue of Elizabeth Line trains taking the Central Tunnel.
- They would run through the Central Tunnel, as just another Elizabeth Line train, stopping at all stations.
- Southend Victoria trains would stop at Stratford, take the fast lines to Shenfield, after which they would stop at all stations to Southend Victoria.
- Ebbsfleet International trains would stop at all stations from Abbey Wood to Ebbsfleet International.
Note.
- Trains would stop at Old Oak Common after it opened for High Speed Two and GWR.
- All ticketing would be contactless.
- Passengers using Heathrow Express to the West of Paddington, would pay an extra fee, but nothing like today’s price.
These Heathrow Express routes would have advantages.
- Southend Airport and Southend Victoria would get a direct fast train to Central London and High Speed Two.
- Heathrow would have a direct connection with Continental train services at Ebbsfleet International.
- Capacity could be increased by going to ten-car trains.
- Heathrow Express could release their platforms at Paddington.
- There would be two fast tph between Heathrow and Stratford.
- There would be two fast tph between Heathrow and Canary Wharf.
- There would be four fast tph between Heathrow and Bond Street for the shopping and Liverpool Street for the City of London.
- There would be four fast tph between Heathrow and Farringdon for Thameslink, Gatwick and Luton Airports.
Heathrow Express trains will be fifteen minutes faster to all destinations.
I don’t think there would be any major disadvantages.

Coeliac Journey Through Covid-19 – Worried About Covid-19
Worried About Covid-19
I think like many others, I was worried about the pandemic when it started.
These are a few of my thoughts and actions.
Attitude To The Internet
I have been an avid reader of the Internet since it started.
But as someone, who has worked with serious researchers off and on for fifty years, I like to think that I know fake news or untrustworthy research when I see it.
I am also in the lucky position, that if I have an advanced question about say DNA, I generally know someone I can ask, with my connections at universities.
I’ve also been used by my cardiologist friend, as an example patient in a couple of his lectures.
Being Coeliac
I was quite worried about whether being coeliac would count against me in the pandemic.
Coeliac UK were not much help and their advice seemed to be along the line of Keep Calm and Carry On!
The Ultra-Orthodox Jewish Community On Stamford Hill
It must have been in 2019, when I was asked by my GP, if I had been vaccinated against measles.
I said no, but I did have a bad case at about twenty-five, which I recounted in A Surprising Question From A Doctor.
He said fine and then added that there’s a measles epidemic in the North of the borough.
Apparently, the ultra-Orthodox Jews have a low level of vaccination and a lot of children.
This worried me, as will they bother to get the vaccine for Covid-19.
They should listen to the eminently sensible Chief Rabbi.
So in the end I just kept calm and carried on!
Coeliac Journey Through Covid-19 – Retirement
Retirement
After my stroke, I was not allowed to drive because of an eyesight problem.
As my late wife and myself had decided we would move back to London on our retirement, I decided to carry-out our plan by myself.
I sold my large house in Suffolk and moved to a smaller one in Dalston in East London.
This is an area, where my many and varied ancestors had strong roots.
My father was born close by and was a direct descendant of a Jewish tailor, who around 1800, was kicked out of Konigsberg in East Prussia, which is now Kaliningrad in Russia, for no other reason than he was male, eighteen and Jewish. I suspect my coeliac disease comes from this Jewish ancestor. No female born into the family has ever successfully given birth and my granddaughter was born with a congenital hernia of the diaphragm, which was successfully repaired by surgery, when she was a few hours old. She now suffers from endometriosis.
My mother’s family were a mix of Huguenots and Devon yeomanry and although she was born a few miles away, her mother was born just round the corner.
My father called himself a London Mongrel and I use the term about myself, as my genes are probably more mixed than his.
Since around the turn of the century, I have been a blogger and around 2008, I started my blog called the Anonymous Widower. The topics, I cover are very varied and have made me quite a few friends.
I am a strong advocate of using blogging to improve peoples’ lives.
Kentish Town Station – 30th April 2023
This article on the BBC is entitled Kentish Town Tube Station Set To Close For Year.
This is the sub-heading.
Kentish Town Tube station is set to close for up to a year while its 26-year-old escalators are replaced.
Other works will also be performed during the closure.
- The ticket office will be removed.
- The ticket barriers will be realigned.
- New paintworks, flooring, wall tiling, and new signage will also be fitted.
These pictures show the current state of Kentish Town station.
Note.
- The Victorian frontage of the station could do with a refurbishment.
- The platforms need to be restored to be the same standard as the clock.
- The escalators don’t look as bad as the article says, but new ones will give them forty years.
- Information around the gate-line for both the Underground and Thameslink, is not to the standards this passenger expects.
- The stairs connecting the London Underground station to the Thameslink bridge could be improved.
- The Thameslink information is good.
- The bridge needs lifts.
There is even a side-gate to access the Thameslink platforms, if the main entrance is closed.
Are More Trains Needed?
For a Sunday morning, both stations were surprisingly busy.
But there were only two Thameslink trains per hour (tph) between Luton and Rainham.
On all days except Sunday, the four tph Sutton Loop Line is usually running, but on Sunday it appears it’s only the Luton and Rainham service.
I suspect the Sunday service will be boosted for the duration of the closure.
Could The Side Gate Be Used Permanently?
The side-gate to the Thameslink platforms will have to be used during the station closure.
But could some arrangement be designed, so that it could be used all of the time?
Conclusion
With an unlimited budget, there’s a lot that could be done at this station.
Ten-Car Hull Trains
On Friday, about eleven in the morning, I was standing on the platform at Finsbury Park station, when unusually I saw a pair of Hull Trains’s Class 802 trains go through as a ten-car train.
A few minutes later, I took a train to King’s Cross, where I took these pictures.
Note.
- The four platforms are numbered from 1 to 4 from the right.
- The Hull Train is in platform 3.
- The fourth picture clearly shows the 11:18 Hull Trains service has ten carriages.
Hull Trains were also selling tickets on the train.
Hull Trains Timetable On April 29th 2023
These trains ran South.
- Beverley-Kings Cross – 0557 – 5 cars
- Hull-Kings Cross – 0824 – 10 cars
- Hull-Kings Cross – 1033 – 5 cars
- Hull-Kings Cross – 1330 – 5 cars
- Hull-Kings Cross – 1531 – 5 cars
- Hull-Kings Cross – 1836 – 5 cars
And these trains ran North
- Kings Cross – 0727-Hull – 5 cars
- Kings Cross – 0948-Hull – 5 cars
- Kings Cross – 1148-Hull – 10 cars
- Kings Cross – 1448-Hull – 5 cars
- Kings Cross – 1748-Beverley – 5 cars
- Kings Cross – 1948-Hull – 5 cars
Note.
- The ten-car trains only run to Hull.
- The daily number of seats between Hull and London has been increased by 16.7 %.
- Four trains are needed to run 5 x five-car and 1 x ten-car trains in each direction.
I can see this timetable being used on other busy days.
World First As HS2 Trials Dual-Fuel Piling Rig On London Site
The title of this post, is the same as that of this news item on HS2.
This is the piling rig.
These are the two bullet points.
- Four piles installed using a hydrogen dual-fuel piling rig, cutting the use of traditional fuel by 36%.
- Trial is the first real world use of the technology on a construction site.
These three paragraphs outline the project.
HS2 has taken a further step forward in decarbonising the constructure sector, completing a world first by installing four 30-metre deep piles on a London site using a hydrogen dual-fuel piling rig.
The trial took place as part of work done in partnership by ULEMCo and Cementation Skanska, working with the world-leading Business Research Establishment (BRE), funded through the BEIS Phase 1 Red Diesel Replacement competition.
ULEMCo and Cementation Skanska successfully modified a medium sized CFA piling rig, converting it so that the machine component operated using energy from on-board hydrogen tanks. Using the dual-fuel system, both diesel and biofuels (HVO) can be mixed with hydrogen, displacing the fuel with hydrogen, resulting in a reduction in fuel use and lower CO2 emissions.
Note.
- We’re going to see a lot more large machines converted to dual-fuel and pure hydrogen.
- ULEMCo from Aintree, seem to be one of the leaders in the field of dual-fuel conversions.
You certainly see lots of these machines working around London and other big cities.
