Not Getting Wet At Paddington Station
On my trip to High Street Kensington station today, I changed trains at Paddington both ways between the Elizabeth and Central Lines.
Going, I took the route I did in The Lizzie Line And Circle/District Line Interchange At Paddington – 1st July 2022.
Coming back, I walked through the station in the dry, despite it chucking it down outside.
At least outside the Elizabeth Line was under a roof and dry.
Despite the rain, the clouds on the glass roof are visible.
The Power Behind Rolls-Royce
My post entitled ‘Spirit of Innovation’ Stakes Claim To Be The World’s Fastest All-Electric Vehicle, was based on this press release from Rolls-Royce, which has the same title.
In the post I talk about Rolls-Royce’s experimental electric aircraft; Sprit of Innovation.
- The aircraft set a world record for electric-aircraft of 345.4 mph.
- the aircraft clocked up a maximum speed of 387.4 mph.
- The aircraft was propelled on its record breaking runs by a 400kW electric powertrain.
- Rolls-Royce worked in partnership with aviation energy storage specialist; Electroflight and automotive powertrain supplier; YASA.
For comparison, my Cessna 340A had two 230 kW engines and a maximum speed of 281 mph.
Electroflight, Evolito And YASA
YASA has this description of the company on their home page.
YASA is at the forefront of eMotor innovation and development. Our axial flux technology motors are up to 4x more powerful than those used in nearly all Electric Vehicles on the road today, whilst being around 50% smaller & lighter.
We already feature in some of the best eMotor applications across multiple sectors, and now as part of Mercedes-Benz, with sites in Oxfordshire and Welshpool, we are accelerating development of axial flux eMotors and Control Systems for of the next generation of Electric Vehicles.
Evolito has this description of the company on their About page.
Evolito was spun out in 2021 by YASA, the world-leading pioneer of automotive axial-flux electric motors acquired by Mercedes-Benz in July 2021, to exclusively commercialise YASA’s next-generation electric motor technology and IP for the rapidly-growing aerospace market. Evolito is funded by a portfolio of private investors including B-FLEXION and Oxford Science Enterprises (OSE).
Electroflight has this company story on their About page.
Founded in 2011 to address battery-electric issues in the aerospace market, we are a UK-based innovation engineering company, taking expertise from across the automotive and aerospace sectors, working with leading airframers to develop and supply next-generation battery technology.
In 2019, Electroflight, Rolls-Royce and YASA partnered to design and build the worlds fastest all-electric vehicle – The Spirit of Innovation. 3 years of dedication from the team involved integrating the full powertrain into a NXT aircraft, optimising the system to peak performance and following rigorous testing processes in an emerging market with new regulations; in 2021 the record breaking flight reached a staggering 345.5 mph!
Following the successful spinout of Evolito (YASA’s Aerospace Division) in 2021, Evolito acquired Electroflight in July 2022 to offer a fully optimised powertrain solution for the electric aerospace industry.
It appears that Mercedes-Benz now own YASA’s technology for the the automotive industry and Evolito have the aerospace technology.
Evolito’s Technology
The Evolito web site has a Technology page, which is entitled The World’s Most Advanced Electric Propulsion Solution.
- Their Axial Flux Motors are certainly a revolutionary approach.
- It looks like one of their motors has a peak power of 280 kW, a continuous power of 100 kW and weighs just 35 Kg.
There is also this page, which gives more details about the creation of the Spirit of Innovation, which has this video.
Evolito And Project Fresson
This press release from Cranfield Aerospace Solutions is entitled Cranfield Aerospace Welcomes Ground-Breaking UK Technology Innovator Onboard Project Fresson.
These paragraphs explain the link-up.
Cranfield Aerospace Solutions (CAeS) welcomes Evolito, a ground-breaking UK technology innovator onboard as the motor & inverter supplier for its hydrogen-powered aircraft demonstrator – Project Fresson.
Evolito join Reaction Engines and Ricardo as technology collaborators on Project Fresson, showcasing the UK innovation that is redefining the aviation industry.
Based in Oxfordshire, Evolito is the aerospace spin out of YASA – the world-leading pioneer of automotive axial-flux electric motors.
Producing the world’s most advanced electric propulsion system, Evolito’s motors are smaller, lighter, and typically 4 times more power dense than radial flux solutions, making them ideally suited to the emerging zero-emissions aviation markets.
Evolito’s axial-flux technology requires up to 75% less iron, less copper and fewer permanent magnets than competing radial solutions, making it lighter and more environmentally friendly.
Note.
- Project Fresson is a project to develop an electric propulsion system for Britten-Norman Islanders.
- There are 700 Islander aircraft in service.
A hydrogen propulsion system, would be useful for new aircraft and conversions.
Electrification Between Newbury And East Somerset Junction
In the August 2023 Edition of Modern Railways, there is an article, which is entitled GWR Seeks Opportunities To Grow.
This is the sub-heading.
Managing Director Mark Hopwood tells Philip Sherratt there is plenty of potential to increase rail’s economic contribution.
This is two paragraphs.
The desire to provide electrification to support aggregates traffic from the Mendip quarries could also benefit GWR , says Mr. Hopwood. ‘Having an electric loco would massively help with pathing heavy freight trains through the Thames Valley. If you could electrify from Newbury to East Somerset Junction, a big chunk of the Berks and Hants route would be wired.
Then you can ask how much further you could get on battery power on an IET without running out of juice.’
I have some thoughts.
Where Is East Somerset Junction?
This OpenRailwayMap shows East Somerset junction.
Note.
- The East Somerset junction is marked with the blue arrow.
- East Somerset junction is 5.2 miles North of Bruton station and 5.4 miles South of Frome station on the Reading and Taunton Line.
As the map shows there is a branch to Merehead Rail Sidings, which is shown in yellow.
This Google Map shows Merehead Rail Sidings.
Note.
- It looks like there is a massive quarry to the North of the A361 road, which curves across the map.
- It is labelled Torr Works – Aggregate Industries.
- Torr Works has a Wikipedia entry.
- The rail sidings are South of the A361.
- Zooming in on the map, shows that the railway between East Somerset junction and Merehead is single-track and only a few miles long.
Distances from East Somerset junction are as follows.
- Dorchester junction – 41.2 miles
- Newbury – 53.4 miles
- Taunton – 37.2 miles
- Weymouth – 47.8 miles
Note that it is electrified with 750 VDC third-rail between Weymouth and Dorchester junction.
Range of Battery-Electric Trains
Consider.
- A Bombardier engineer told me eight years ago, that the battery-electric Class 379 train had a range of sixty miles.
- Stadler’s FLIRT Akku has a Guinness world record of 139 miles on one battery charge. See this page on the Stadler web site.
- Even Stadler’s Class 777 trains for Merseyrail have a range of 84 miles on battery power. See New Merseyrail Train Runs 135 km On Battery.
It does appear that five-car battery-electric trains will have ranges in excess of a hundred miles.
I believe that because Hitachi’s battery makers have a good record, they will probably be very ambitious and will want that Guinness record, that Hitachi’s Class 802 trains will have a battery range not far short of the 139 miles of the Stadler FLIRT Akku.
I will be very surprised if Hitachi’s battery-electric version of a Class 802 train, doesn’t have range of at least 125 miles.
But say if they could do say 140 miles, the battery-electric Class 802 train could cover every long-distance route in the UK, which would attract orders for trains to run on the following routes.
- Cardiff and Swansea
- Crewe and Holyhead
- Edinburgh and Aberdeen
- Edinburgh and Inverness
- Crewe and Holyhead
- London Waterloo and Exeter St. Davids
A substantial reward to the battery makers, would probably not be out of order.
Aggregate Trains From The Mendips
Consider.
- Mining and quarrying companies are under pressure from governments, shareholders and environmentalists to reduce their carbon footprints.
- Many are replacing diesel-powered mining excavators and trucks, with electric or hydrogen versions.
- In addition, those companies delivering building products to the construction industry are under pressure to provide low-carbon products.
- Using rail with electric traction to deliver products to market would cut carbon emissions and might even help sales.
These Mendip quarries appear to be connected to the Reading and Taunton Line.
- Torr Works – Connects 5.4 miles to the South of Frome.
- Whatley Quarry – Connects close to Frome.
There may be others.
But these rail-connected quarries, connect at or North of East Somerset junction, to where Mark Hopwood is proposing electrification.
Zero-carbon rail traction could even be possible, by electrifying the short single-track branch lines. or by using hydrogen-electric hybrid locomotives.
GWR’s London And South-West Services
These services use the Reading and Taunton Line to join the Bristol and Exeter Line at Taunton, before going on to Exeter, Plymouth and other destinations in the South-West of England.
These are distances from East Somerset Junction.
- Exeter – 67 miles
- Paignton 95.2 miles
- Penzance – 198.5 miles
- Plymouth – 119.0 miles
- Taunton – 37.2 miles
Note.
- Exeter, Paignton, Penzance and Plymouth stations would need short lengths of electrification to charge terminating trains or top-up passing trains.
- In Thoughts About Electrification Through Devon And Cornwall, I showed that the average stop time at Plymouth station was eight minutes, which could be enough for the rail equivalent of a Formula One splash and dash.
- A 125 mile battery range, not only enables London and Penzance, but also Cardiff and Swansea, and Edinburgh and Aberdeen, when the extra electrification is completed.
Could my estimate of a 125 mile battery range, be Hitachi’s objective for their battery-electric trains?
The Ultimate Battery-Electric Class 802 Train
Hitachi have been totally silent on how the fitting of batteries to Class 802 trains is going.
But Mark Hopwood is more forthcoming in the GWR Seeks Opportunities To Grow article. where this is said.
Meanwhile, GWR had announced plans with Eversholt Rail to trial the replacement of a diesel generator unit with batteries on a Class 802 IET. However, Mr. Hopwood says this would not be useful for GWR and so the trial is not proceeding; instead, a TransPennine Express Class 802 will be the subject of a battery trial.
It sounds to me that another solution is being developed to get trains to run on electric power between London and the South-West.
- I think we can rule out full electrification on the grounds of cost, disruption, time and the Nimbys and objectors will have a field day.
- Newbury and Penzance is a distance of 251.9 miles, which would surely need a lot of batteries.
Mark Hopwood’s idea to electrify the 53.4 miles between Newbury And East Somerset junction, is starting to look like a good compromise.
GWR’s Bristol/Gloucester And Weymouth Services

Note.
- I would assume that there is enough electrification at Bristol Temple Meads and towards Gloucester to charge the trains.
- Trains would leave Bristol Temple Meads with a full battery.
- The eighteen stops mean that an electric train with regenerative braking will be more efficient.

Distances of the various legs are as follows.
- Swindon and Chippenham – 16.9 miles – Electrified
- Chippenham and Westbury – 15.8 miles – Not Electrified
The section without electrification, should be well within range of a battery-electric train, that has been designed for the route.
What Can Be Done If The Electrification Is Not Long Enough?
Some of these routes battery-electric routes may need more electrification to work efficiently.
Despite some routes having both 25 KVAC overhead and 750 VDC third-rail electrification, any extension of the electrification would be overhead, as new third-rail electrification is effectively banned.
Conclusion
It looks like Mark Hopgood proposal is an excellent idea to enable the decarbonisation of GWR services in Wiltshire and Somerset.
- Express services would be run by battery-electric Class 802 trains.
- Local services would be run by battery-electric trains with perhaps three cars.
Some of the local trains would need to be dual-voltage to use both forms of electrification.
Northumberland Line: Construction Of New Stations To Begin
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
The construction of three stations for a new Northumberland rail line is set to begin.beec
These are the first three paragraphs.
Northumberland County Council said contracts had been exchanged for work to start on Bedlington, Blyth Bebside and Seaton Delaval Stations.
The project is described as a “key milestone” to restore passenger services lost in the 1960s.
It is planned to run a half-hourly passenger service along the 18-mile (29km) lines.
It certainly seems that the reopening of this line is progressing.
Ozzy Puts The Bull Into New Street Station
I went to Birmingham New Street station today to see Ozzy, the Birmingham Bull in his new home.
I don’t think we’ve seen such a camera frenzy in the UK, since the days of Princess Diana.
In The Birmingham Bull – 5th August 2022, there are pictures of the Bull a year ago. Ozzy has changed, but a year ago, he wasn’t intended to be permanent.
This picture is from last year.
There are differences. Note the loader underneath to give the artwork movement.
A year ago, I said this in the post.
This wonderful work of engineering art, is far too good and is now too well-loved to be scrapped.
As it needs to go inside, why not bring it inside High Speed Two’s new Curzon Street station, to greet passengers visiting Birmingham?
Ozzy has found a new permanent home in Birmingham New Street station, but I wouldn’t rule out a move to Curzon Street station, for several decades.
West Midlands Metro – Eastside Extension – 26th July 2023
These pictures show the current state of the Eastside Extension of the West Midlands Metro.
Note.
There is a triangular junction, where the lines split to the South of the Bull Street tram stop.
The Eastside Extension will run past Curzon Street station and then on to somewhere around Digbeth Coach station.
There is a triangular junction, where the lines split to the South of the Bull Street tram stop.
Through Birmingham City Centre On A Tram – 26th July 2023
When I get to a new city, I like to take a tram across the City Centre taking pictures.
I realised, that I’d never done this in Birmingham before, so I did it today on the West Midlands Metro.
Note.
It will be better, when the gaps are filled in.
- I got on at Brindleyplace.
- I got off at Grand Central.
This was my all-day Zone 1 ticket, that I used to go up and down all day.
For just £2.80 all day, you can go between Edgbaston Village and Jewellery Quarter, as much as you need.
Sussex Will Be Leader In Hydrogen Energy Production
The title of this post, is the same as that of this article on The Argus.
These are the first three paragraphs.
The county is today launching its bid to become a pioneer for use and production of hydrogen energy.
Experts will unveil Brighton’s hydrogen strategy this morning showing how the city and surrounding areas are championing a clean energy infrastructure.
With plans for a Worthing crematorium to become the first in the world powered entirely by hydrogen, development of a green energy production facility in Shoreham, and a growing fleet of hydrogen-powered buses in Crawley, the region is already breaking ground in the hydrogen industry – and shows no sign of stopping.
These are my thoughts.
The Plan Is Comprehensive
This document of the Council website, is entitled the Greater Brighton Hydrogen Strategy.
It is very comprehensive and discusses hydrogen in Sussex from all angles.
Every Council in the UK needs to have their own comprehensive strategy like this.
The Report Cautions That Greater Brighton May Need More Renewable Energy
Consider.
- The Rampion wind farm, with a capacity of 400 MW is already operating in the sea South of Brighton.
- This should be joined by the 1200 GW rampion 2 wind farm in the next few years.
It is unlikely substantial onshore wind and solar farms will be built in the area.
Gatwick Airport Is Expected To Need A Hydrogen Supply
The strategy says this about Gatwick and the two Rampion wind farms.
The offshore wind farm Rampion is large enough to be considered nationally significant infrastructure. There
is a second development for this wind farm planned for 2025-6, which will connect into Bolney substation as
per the existing wind farm.The GBEB energy plan suggested that an electrolyser could be sited there, although there are no identified demand locations nearby other than potential refuelling of passing traffic on the A23.
However, considering the relative distance to Gatwick airport, which is expected to be a significant future
demand, there may be an opportunity for a direct pipeline. This would be further into the future and requires
further analysis and bilateral engagement between Rampion and Gatwick. Engagement with Rampion found
that, given the large population supplied by the Rampion wind farms, and the relative lack of other large-scale
renewables locally, these wind farms are unlikely to face significant curtailment and will fully contribute to
decarbonising the local electricity grid. Therefore, using Rampion to produce hydrogen by electrolysis is not
seen as the best use case in the near term.
It looks to me, that because of the electricity demand in the Brighton and Gatwick area, that a big decision needs to be made to create some more renewable capacity.
Could this mean a Rampion 3 or perhaps a fleet of small modular nuclear reactors at Dungeness?
An Electrolyser At Bolney Substation
This Google map shows the position of Bolney substation.
Note.
- The A23 is the main London-Brighton road.
- Bolney substation is indicated by the red arrow.
- The substation doesn’t have very good road access.
- I also suspect that the locals wouldn’t like an electrolyser in their midst.
On a brief look, I suspect that an electrolyser at Bolney substation will be a non-starter.
Shoreham Port As A Hydrogen Hub
The strategy mentions Shoreham Port several times, but gives the impression that progress is slow.
This Google Map shows Shoreham Port.
Note.
- Shoreham is in the West.
- The port reaches a long way to the East.
- The 420 MW gas-fired Shoreham Power station, is at the Eastern end of the port, close to the sea.
There appears to be spaces along the water for developing hydrogen infrastructure.
This page on the H2Green web site is entitled Agreement to Develop Clean Energy Hub for Shoreham Port, Sussex, starts with this paragraph.
Getech, the geoscience and geospatial technology provider and data-led energy asset developer, is pleased to announce that its wholly owned hydrogen subsidiary, H2 Green, has signed a Collaboration Agreement (the “Agreement”) with Shoreham Port.
It lists these three highlights.
- H2 Green granted a two-year legally binding exclusive right to develop a renewable energy hub (the “Hub”) at the Port of Shoreham, West Sussex.
- Under plans submitted by H2 Green to Shoreham Port, the Hub will initially focus on the provision of green hydrogen and renewable electricity to the Port’s fleet of 39 heavy forklift trucks and 12 heavy goods vehicles.
- Green Hydrogen will be sourced by a scalable green hydrogen production, storage and refuelling facility – the economics of which will be optimised by its integration with new solar and wind electricity generation capacity.
- The Hub will then be expanded to facilitate the decarbonisation of more than 800 heavy goods vehicles that enter Shoreham Port daily, and to provide fuel to port and coastal marine vessels.
That is all good stuff, but I do wonder, where the renewable electricity is going to come from.
In Further Thoughts On BP’s Successful INTOG Bid, I looked at BP’s plan for a 50 MW wind farm.
- It will be about twenty miles offshore from Aberdeen.
- With an appropriate electrolyser 50 MW of electricity would produce twenty tonnes of hydrogen per day.
- The electrolyser could be onshore or even offshore.
- The technology has all been developed.
Could H2Green be thinking of developing a similar hydrogen production facility?
A Walk Over Wandsworth Bridge – 25th July 2023
This article on the BBC is entitled Wandsworth Bridge Closes For 10 Weeks Of Repairs.
This is the sub-heading.
A 10-week closure of Wandsworth Bridge for “essential safety repairs” has begun, Wandsworth Council says.
These are the first three paragraphs.
The authority added that the work was needed “to safeguard the long-term future of this key river crossing”.
Transport for London (TfL) has warned passengers that bus services which use Wandsworth Bridge will be diverted or stop short of normal destinations.
It added that the bridge would remain open for pedestrians, while cyclists can cross if they dismount.
So I went to have a look, starting at Wandsworth Town station.
It is a station, that needs a single lift and perhaps a small amount of refurbishment.
I walked from the station and over Wandsworth Bridge and along Wandsworth Bridge Road.
Note.
- There were several restaurants and cafes.
- It was a level walk.
- It looks like the Council was taking the chance to resurface the bridge.
- Along Wandsworth Bridge Road, drivers were not keeping to the 20 mph speed limit.
Some cyclists were still cycling on the bridge.
Il Pagliaccio Restaurant
I had lunch in the Il Pagliaccio Restaurant.
It was a typical friendly Italian restaurant, that served gluten-free food.
Are The Elizabeth Line Trains Ready To Be Lengthened?
When Transport for London updated the North and East London Lines of the London Overground in the early years of this century, they felt that four-car Class 378 trains would have enough capacity for the lines. But the lines proved more popular than, they had expected and the trains were very overcrowded. So it was decided to lengthen the trains to the five cars they are today.
This wasn’t as easy as it seems, as platforms at several stations had to be lengthened, which was disruptive and expensive.
One day last week, I was in Farringdon station and took these pictures of the platform edge doors at the back end of a Class 345 train.
Note how, that when a train is in the station, it doesn’t reach to the end.
But this is not always the case, as this picture from Paddington station shows.
Does this mean that some underground Elizabeth Line platforms are longer than others?
In Bombardier’s Plug-and-Play Train, I discuss the plug-and-play design of Aventras.
- This plug-and-play design allows trains to be lengthened or shortened by adding or removing carriages.
- Class 345 trains are actually two half-trains, with a trailer car in between them.
So is this why Class 345 trains have run services as both seven-car and nine-car trains?
The former have three-car half-trains and the latter have four-car half-trains, with an extra MS car.
Talk Of Eleven-Car Trains
If you search the Internet, you’ll find forums and web pages speculating about. whether the trains will be lengthened to ten-cars or even eleven-cars.
Consider.
- The current trains are 204.73 metres long.
- Extra intermediate cars are all 22.5 metres long.
- The trains also are probably fitted with selective door opening or can be as most modern trains have it.
This would mean, that a ten-car train would be 227.23 metres long and an eleven-car train will be 249.73 metres.
The eleven-car figure is just 27 centimetres short of 250 metres.
I wouldn’t me surprised if the maximum train length was given to Bombardier as 250 metres.
I certainly feel, that if it should be decided to lengthen the trains by adding another carriage or two, that this will not be a problem.
The Elizabeth Line’s Two Problems
These posts talk about the two problems.
In TfL Needs More Elizabeth Line Trains Because Of HS2 Delays At Euston, I talked about what happens, if High Speed Two doesn’t link initially to Euston.
In Elizabeth Line: Commuters Say Service ‘Not What Was Promised’, I talked about problems of overcrowding at the Western end of the line.
The solutions to both problems are either more trains or adding more carriages to existing trains.
In this article on Ian Visits, which has the same title as the first post, Ian says this about ordering more trains.
Although HS2 isn’t expected to open until some point between 2029-33, TfL is warning that it will need to place the orders for the new trains soon, as the cost of doing so later will be significantly more expensive. That’s because the factory lines to build Elizabeth line trains at Alstom’s factory in Derbyshire are still in place, but will be demobilised soon. If the trains aren’t ordered before that happens, then the cost of reactivating the factory lines has to be included in the bill.
I suspect, it probably applies to an order for extra carriages as well.
Problems For Alstom
But will a substantial order for more Class 345 trains or carriages cause problems for Alstom at Derby?
This extract from the Wikipedia entry for High Speed Two rolling stock, describes how the Hitachi-Alstom joint venture will build the Classic-Compatible trains for High Speed Two.
Vehicle body assembly and initial fitting out of the trains will take place at the Hitachi Newton Aycliffe factory, the bogies will be manufactured at the Alstom factory in Crewe, and final assembly and fit-out, including the interiors, electronics and bogies, will take place at Alstom’s factory in Derby.
If more Class 345 trains are to be built at Derby, does it mean a rethink by the joint venture?
In Battery EMUs Envisaged In Southeastern Fleet Procurement, I talked about how Southeastern were looking for new trains. Given that Aventras from Alstom could be in the frame for these new trrains for Southeastern, does that give Alstom more complications?
The Anonymous Widower
