A Black Cab With Cushions
I must have used thousands of black taxis in my life.
But last week, was the first one with cushions.
Even at seventy-six, I still get new experiences.
The Best Plane That Looks Like An Egg
The title of this post is the same as that of this article on interesting Engineering.
This is the sub-heading.
Celera 500L: Redefining aviation with its unique egg-shaped design, unparalleled fuel efficiency, and affordability.
These are the first two paragraphs.
In the world of aviation, where innovation meets the boundless sky, a groundbreaking aircraft is poised to redefine the future of air travel. Meet the Celera 500L, the brainchild of the Otto Aviation Group, an aircraft that not only boasts a distinctive egg-shaped design but also promises to transform the way we think about flying. Set to enter production in 2025, the Celera 500L is a testament to cutting-edge technology and forward-thinking design, promising to make air travel more cost-effective and eco-friendly than ever before.
One cannot help but be captivated by the Celera 500L’s futuristic aesthetics. Its unmistakable egg-shaped design is a departure from the traditional aircraft we’ve grown accustomed to seeing in the skies. However, this unique shape is not just for show; it’s the result of meticulous engineering aimed at reducing drag and maximizing efficiency.
I suggest you read the article and look at Interesting Engineering’s video.
After that have a good look at Otto Aviation’s web site.
Brief details of the business aircraft version are scattered through the pages.
- Passengers – 6
- Range – 5,000 miles
- Fuel-consumption – 33 miles per gallon.
- Power – Single pusher diesel engine.
The Otto Aviation web site, explains how it is done using laminar flow and advanced aerodynamics.
There is also this page on the ZeroAvia web site, which is entitled ZeroAvia & Otto Aviation Partner to Deliver First New Airframe Design with Hydrogen-Electric Engine Option.
Is a new world of aviation emerging?
Extending The Elizabeth Line – Could Open Access Services Use The Elizabeth Line?
In the February 2024 Edition of Modern Railways, there is an article which is entitled First Bid For Sheffield To King’s Cross Paths.
The article is mainly about FirstGroup’s proposal for a new Sheffield and London service, running under the Hull Trains brand.
But, this is the last paragraph.
Modern Railways understands First is working on a number of proposals for additional open access services, and this is an early statement of intent. Other existing open access proposals include Grand Union Trains’ plans for London to Stirling and Cardiff to Edinburgh services, along with an already approved London to Carmarthen service, and the recently submitted Wrexham, Shropshire and Midland Railway application for a London to Wrexham service. It is understood other organisations, including MTR and Virgin, are also working up plans for new open access services.
The respected Modern Railways magazine seem to think, that we’ll be seeing more open access services on UK railways.
These are my thoughts.
A Simple Example – London Crosslink
In Extending The Elizabeth Line – London Crosslink, I said this.
In the Wikipedia entry for the London Crosslink, this is the introduction.
London Crosslink was a passenger train service operated by Anglia Railways between Norwich and Basingstoke, using the North London Line to bypass central London. Class 170 Turbostar diesel multiple units were used, and the service operated between 22 May 2000 and 28 September 2002, supported by funding from the Strategic Rail Authority through its Rail Passenger Partnership fund.
As it was discontinued and it doesn’t seem to be sadly missed, I’m not advocating its reinstatement, but just looking how it might be run after the full opening of the Elizabeth Line.
But surely, there were good reasons, why the service was run in the first place and there might be a need in the future.
These are some characteristics of the service.
- There were about half-a-dozen services in both directions every day.
- At its full length it ran between Norwich and Basingstoke.
- Stops included Diss, Stowmarket, Ipswich, Colchester, Witham, Chelmsford, Ingatestone, Romford, Stratford, Highbury & Islington, Camden Road, West Hampstead, Brentford, Feltham, Staines, Woking and Farnborough (Main).
- Each service seemed to have a different stopping pattern.
- The timetable wasn’t very regular.
- The route wasn’t fully electrified.
It appears that it may have been a difficult service to timetable.
I lived North of Ipswich for some years.
I never used the London CrossLink service, as I had moved away before the service started in 2000.
- I would have found the change to the Central Line at Stratford station useful.
- I would have found the change to the Victoria Line at Highbury & Islington station useful.
- I would have found the change to Thameslink at West Hampstead station useful.
- Basingstoke would have given access to Greater South-West England.
- I could have got a bus to Heathrow from Feltham.
But getting to Marylebone, Paddington and Waterloo would have still been tedious.
Could a replacement for the London CrossLink be routed via the Elizabeth Line?
- The service would use the Elizabeth Line between Stratford and Reading.
- The service would use the Reading and Basingstoke Line between Reading and Basingstoke.
The route has some advantages over the original route.
- Except for the 13.6 miles between Southcote Junction and Basingstoke, the route is fully-electrified.
- Whitechapel will give access to London Overground services.
- Farringdon will give access to Thameslink services.
- There will be a lot of connections at Tottenham Court Road and Bond Street.
- Paddington and Reading will give access to Heathrow, Oxford and West of England services.
- Basingstoke will give access to Greater South-West England.
It is certainly an as-useful route as the original, if not more so.
The Trains
In Extending The Elizabeth Line – Will There Be A Need For Long Distance Class 345 Train?, I set out how a standard Class 345 train could be updated with faster running and a more appropriate interior.
As the Elizabeth Line is likely to need some more trains if High Speed Two is delayed, perhaps some extra trains should be ordered fairly soon.
The Routes
Consider.
- A terminal station would probably need to be electrified to the Elizabeth Line route.
- It would need the infrastructure to turn the trains.
These stations could probably be used as terminal stations.
- Basingstoke
- Bristol
- Cardiff
- Colchester
- Faversham
- Hoo – See Extending The Elizabeth Line – A Branch To The Isle Of Grain.
- Ipswich
- Northfleet – For European services at Ebbsfleet International.
- Norwich
- Oxford
- Rochester
- Southampton
- Southend Victoria
There will certainly be others.
Why Use Open Access?
Suppose an operator wants to run a service between Bristol Parkway and Northfleet to give the West Country access to European services.
- The operator takes all the risk and Network Rail get track access charges.
- Do Transport for London get track access charges for the Elizabeth Line tunnels?
- If they get their predictions and sums wrong, they lose the money.
But if they get it right, they probably sell it to an infrastructure company at a profit.
Conclusion
I think open access operation might work through the Elizabeth Line Tunnels.
Project To Improve Mobile Connectivity On East Coast Main Lone Reaches Key Milestone
The title of this post, is the same as that of this press release on LNER.
This is the sub-heading.
LNER, Network Rail and Mobile Network Operators (MNOs) are collaborating to improve mobile connectivity on the East Coast Main Line.
These three paragraphs outline the project.
The joint project, which is delivering new mobile phone infrastructure into tunnels outside London King’s Cross station, has reached an important milestone, with the installation of a bespoke antenna. The work inside Gasworks and Copenhagen tunnels will mean most customers can expect a more reliable and consistent mobile phone and on-train Wi-Fi connection and see the removal of ‘not-spots’ customers can experience when travelling through the tunnels.
The successful delivery of the project, funded by LNER working in collaboration with Network Rail and major mobile network operators, will mean the tunnels will be the first on the country’s operational railway to be fitted with the bespoke solution, with the system installed by rail connectivity and technology integration specialist Linbrooke. Rigorous testing has been carried out at Network Rail’s Innovation and Development Centre between Network Rail and the phone companies before introduction onto the network.
The technology will mean from later this year most customers will be able to maintain direct voice and data access to their mobile provider, keeping their calls connected and meetings online as they approach and leave the capital.
Anything that improves connectivity is to be welcomed.
New British Steel Rail Stocking Facility Will Boost Network Rail Supply Chain
The title of this post, is the same as that of this article on RailUK.
These four paragraphs outline the new facility and how it will work.
British Steel is building a new £10 million rail stocking facility, the biggest of its kind in the country.
The facility, at the company’s Scunthorpe site, is scheduled to be completed this summer and will stock around 25,000 tonnes of 108-metre finished rail.
The investment is part of our British Steel’s strategy to support the supply of 56E1 and 60E2 section rails for Network Rail, ensuring there is rail stock readily available for its supply chain.
Rails stocked in the new facility will all have undergone the stringent testing and quality assurance checks required to meet the specification to allow immediate dispatch or welding into 216-metre lengths to the customer.
With all the gloom in the steel industry, It’s good to see someone investing in new facilities.
Ten Spanish Companies Join Forces To Apply Hydrogen Propulsion To A High-Speed Train For The First Time
The title of this post, is the same as that of this press release from Talgo.
These are the three bullet points.
- The Hympulso project is part of the Strategic Projects for Economic Recovery and Transformation (PERTES)
- A new technical car with hydrogen and batteries to be developed for a Talgo 250 train, allowing it to run on clean energy on non-electrified lines.
- The main partners are Talgo, Golendus, Ingeteam, Repsol, Sener and Optimus3D.
These are the first four paragraphs.
Ten Spanish companies have joined forces to design, build and install, for the first time in the world, a propulsion system based on renewable hydrogen fuel cells on a high-speed train. Under the Hympulso project, the companies will develop a set of technologies that can be applied to the Talgo 250 ‘all-terrain’ train, making it possible to electrify the rail network with energy generated entirely from renewable sources, even on lines without overhead power lines.
Led by Talgo, Hympulso also includes Golendus, Ingeteam, Optimus3D, Repsol and Sener as partners. Universidad Pontificia Comillas and Tecnalia are collaborators, while Adif is an observer. The initiative has received a grant of €6.5 million and is part of the Incentive Programme for the Innovative Value Chain and Knowledge of Renewable Hydrogen, as part of the Recovery, Transformation and Resilience Plan.
Hympulso will be comprehensive in nature: it will activate the entire renewable hydrogen value chain in the railway system, from production to consumption. The project will also make it possible to analyse the impact of the future transition on the various railway infrastructure assets managed by Adif, such as maintenance facilities or the track.
Thus, the project will result in a joint output of hydrogen supply installations adapted to railways -both mobile and static- and a pioneering prototype of a hybrid bimodal train for passengers with automatic track-gauge change, which will be able to run both on conventional and high-speed networks, using catenary supply when available, or hydrogen and batteries in those corridors that are not electrified.
This picture shows a visualisation of the train.
Note.
- There is a power car containing the hydrogen fuel cells and other gubbins behind the one or both locomotives.
- Hydrogen power is used, where there is no electrification.
- Talgo already make a high speed train with a diesel power pack, so engineering would only involve developing a new hydrogen power pack.
My only questions are.
- Do the trains come without gauge-changing?
- Could they be run on a typical UK rail line?
- Do they speak, Cornish, Gaelic and Welsh?
If the answer to all questions is yes, then this must be the ideal train for these routes.
- London Euston and Aberystwyth
- London Euston and Holyhead
- London King’s Cross and Aberdeen.
- London King’s Cross and Cleethorpes/Grimsby
- London King’s Cross and Inverness.
- London King’s Cross and Thurso/Wick.
- London Paddington and Carmarthen
- London Paddington and Penzance
Note.
- No more electrification on these routes would be needed.
- The trains could use High Speed Two to wherever it goes.
- The trains could do 140 mph on the Great Western Main Line, East Coast Main Line and West Coast Main Line.
Hympulso looks a very comprehensive, professional and practical plan, that could easily be adapted to the UK mainland.
HyperTunnel Wins Government Backing For Revolutionary Underpass Tech
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the sub-heading.
Pioneering tunnel builders hyperTunnel have scored a major coup, securing UK government funding to showcase their revolutionary swarm construction technique at the Global Centre of Rail Excellence (GCRE) in South Wales.
These four paragraphs outline hyperTunnel and its demonstration project at the GCRE.
Their underpass project is one of just 16 cutting-edge schemes set to be unveiled at the GCRE’s Dulais Valley site this year. hyperTunnel’s brainchild, the swarm construction technique, harnesses the power of AI, digital surveying, and robot swarms to essentially 3D print tunnels directly in the ground, eliminating the need for messy excavation.
This futuristic approach it hopes will transform underground construction, whilst slashing costs and timeframes. It can also help contribute to waste reduction, risk prevention and help reduce a projects carbon footprint compared to the traditional cut-and-cover methods which are frequently used.
Their GCRE project will see them build a 20-metre pedestrian underpass beneath a test track, cleverly designed to keep the track operational throughout construction.
hyperTunnel’s overarching vision is to offer a financially viable alternative to perilous level crossings which it anticipates will boost safety, and increase rail capacity.
Note.
- To learn more visit hyperTunnel’s web site.
- The mission statement on the home page is Transforming Underground Construction Through AI, Machine Learning And Swarm Robotics.
I like this technology and think it will go a long way. Hopefully, in the right direction.

- Five-car – 176
- Seven-car – 4

That is a total of 1254 trains that need to be decarbonised by either replacement or modification.
- Some trains are effectively double-counted, as both the current trains and their replacements are included.
- Some trains are planned to be replaced by electric trains.
- Some trains will be passed on.
But there are still a lot of trains to be decarbonised.
I will now look at each group in detail.
BR Second Generation Trains
- Class 150 – 129 x two-car and 6 x three-car.
- Class 153 – 36 x one-car.
- Class 155 – 7 x two-car.
- Class 156 – 109 x two-car.
- Class 158 – 155 x two-car and 15 x three-car.
- Class 159 – 29 x three-car.
- Class 165 – 59 x two-car and 16 x three-car.
- Class 166 – 21 x three-car.
Note.
- The trains have mostly Cummins engines, with some Perkins and a spattering of Rolls-Royce.
- Class 150,153, 155 and 156 trains are 75 mph trains and most of the others are capable of 90 mph.
- Condition of the interiors is variable, with some being excellent and others being terrible.
- There are 36 x one-car, 459 x two-car and 59 x three-car.
- There appears to be no plan to decarbonise these trains.
- Some will be replaced by new CAF diesel trains or new electric trains.
The best use of some of the better trains in this group would be to fill-in until zero-carbon trains are available.
Turbostar Trains
These trains are all Turbostars or their predecessor.
- Class 168 – 9 x two-car, 9 x three-car and 13 x four-car.
- Class 170 – 34 x two-car and 71 x three-car.
- Class 171 – 17 x three-car.
- Class 172 – 24 x two-car and 15 x three-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 100 mph.
- Condition of the interiors is generally good.
- There are 67 x two-car, 112 x three-car and 13 x four-car.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- 168329 has been converted into a diesel-hybrid, by Rolls-Royce mtu.
I feel that one way or another, the trains in this group should be capable of converting to net-zero operation.
Alstom Coradia, Bombardier Voyager and Siemens Desiro Trains
I am putting these trains together, as they are all 100-125 mph long-distance trains, that are not that old.
- Class 175 – 9 x two-car and 15 x three-car.
- Class 180 – 1 x four-car and 12 x five-car.
- Class 185 – 51 x three-car.
- Class 220 – 34 x four-car
- Class 221 – 24 x four-car and 18 x five-cars
- Class 222 – 23 x five-car and 4 x seven-car.
Note.
- The trains all have Cummins engines.
- They are capable of 100 mph or 125 mph.
- Condition of the interiors is generally good.
- There are 9 x two-car, 66 x three-car, 59 x four-car, 53 five-car and 4 x seven-car.
- Cummins engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- In Grand Central DMU To Be Used For Dual-Fuel Trial, I described innovative fuel trails in a Class 180 train.
- I suspect Cummins will be taking an interest.
In Cummins And Leclanché S.A. To Collaborate On Lower-Emissions Solutions For Use In Marine And Rail Applications, I asked this question.
How many of these trains could be converted to hybrid operation, if Cummins and Leclanché were to create their version of the mtu Hybrid PowerPack?
I feel that one way or another, the trains in this group should be capable of converting to net-zero operation.
CAF Civity Trains
These three trains have all been recently introduced
- Class 195 – 25 x two-car and 33 x three-car.
- Class 196 – 12 x two-car and 14 x four-car.
- Class 197 – 51 x two-car and 26 x three-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 100 mph.
- Condition of the interiors is probably as-new!
- There are 88 x two-car, 59 x three-car and 14 x four-car.
- All these trains were ordered between 2016 and 2018.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
I don’t believe that as these trains were only ordered a few years ago, that the trains were bought with the knowledge of a route which would convert these trains to net-zero operation.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing the Rolls-Royce mtu engines with mtu Hybrid PowerPacks.
- Running the trains on sustainable fuel.
The work needed would probably be the same for all trains.
Stadler FLIRT Bi-Mode Trains
- Class 231 – 11 x four-car.
- Class 755 – 14 x three-car and 24 x four-car.
- Class 756 – 7 x three-car and 17 x four-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of between 75 and 100 mph.
- Condition of the interiors is probably as-new!
- There are 21 x three-car and 52 x four-car.
- All these trains were ordered between 2016 and 2018.
- As with other recently ordered trains, I am fairly sure that the Deutz engines will be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
Stadler have designed these trains, so that diesel engines can be replaced by battery packs.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing all or some the Deutz engines with battery packs.
- Running the trains on sustainable fuel.
The work needed would probably be the same for all trains.
Hitachi AT-300 Trains
Only the bi-mode trains are lists.
- Class 800 – 31 x five-car and 49 x nine-car.
- Class 802 – 46 x five-car and 14 x nine-car.
- Class 805 – 13 x five-car.
- Class 810 – 33 x five-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 125 mph.
- Condition of the interiors is probably as-new!
- There are 123 x three-car and 63 x nine-car.
- Most were built after 2016.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- Hitachi are developing battery packs for these trains.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing all or some the Rolls-Royce mtu engines with battery packs.
- Running the trains on sustainable fuel.
The work needed would probably be the same or similar for all trains.
Old Street Station – 22nd January 2024
I passed through Old Street station this morning and took these pictures.
Note.
- I arrived at the station on a Great Northern train from Moorgate.
- I walked through the dingy tunnels of the old station and then used the escalator to get to the surface.
- I then walked around the centre of the roundabout, before walking to the Southbound bus stop.
- From there I took a 21 bus to take the last few pictures.
- I wrote the first post about construction at Silicon Roudabout; Silicon Roundabout Goes Two-Way, in May 2019.
This really has been a slow construction job.
The Anonymous Widower
