FirstGroup Applies To Run New London To Sheffield Rail Service
The title of this post, is the same as that of this press release from First Group.
These four paragraphs outline FirstGroup’s initial plans.
FirstGroup plc, the leading private sector transport operator, has today submitted the first phase of an application for a new open access rail service between London and Sheffield to the Office of Rail and Road (ORR).
FirstGroup plans to expand its open access rail operations as part of its award-winning Hull Trains business, building on their successful existing service which has transformed long-distance connectivity between Hull and London.
FirstGroup’s new proposals comprise two return journeys a day from London King’s Cross, calling at Retford, Worksop, Woodhouse and Sheffield, and the company aims to provide a faster link between London and Sheffield than alternative services. Almost three quarters of trips between London and Sheffield are currently made by car, with a further 9% of trips made by coach, and a competitively priced new rail offering will help stimulate a shift in transport mode of choice from road to rail.
The new proposed route will give Sheffield the first regular service from London King’s Cross since 1968 and will also give Worksop in Nottinghamshire the first regular direct London trains in decades. FirstGroup estimates there are 350,000 people in the Worksop and Woodhouse catchment areas who will have direct rail access to London because of these proposals. A sizeable number of rail users in these areas currently drive to Doncaster station to pick up faster services to London rather than travelling via Sheffield, and a convenient rail offering from local stations will also help to reduce the number of these car journeys.
Note.
- The press release says this is only the first phase.
- It appears to be an extension of Hull Trains.
- Comments on a news story based on the press release in The Times, have been generally positive.
These are my thoughts.
The Two Routes Are Similar
Consider.
- Beverley is 44.3 miles from the electrified East Coast Main Line at Temple Hirst Junction.
- Hull is 36.1 miles from the electrified East Coast Main Line at Temple Hirst Junction.
- Sheffield is 23.5 miles from the electrified East Coast Main Line at Retford station.
- There is no electrification at Beverley, Hull or Sheffield.
Note.
- Trains must be capable of having a range sufficient to go from the East Coast Main Line to the destination and back again.
- It is slightly surprising that Sheffield station is closest to the electrification of the East Coast Main Line.
- Hull Train’s electro-diesel Class 802 trains regularly handle the 88.6 miles to Beverley and back.
It does look like an appropriate number of Class 802 trains could handle Hull Trains current and future services to Beverley, Hull and Sheffield.
Hull Trains Need Ten-Car Trains
Consider.
- In Ten-Car Hull Trains, I show some details of Hull Trains using a pair of five-car trains.
- I’ve since seen ten-car Hull Trains regularly.
- There were two ten-car services on the 29th December 2023 between London King’s Cross and Hull.
Hull Trains must procure enough trains for all possible scenarios.
Intermediate Stations Of The Two Routes
Intermediate stations are.
- Going North from London King’s Cross to Hull, trains call at Stevenage (limited), Grantham, Retford, Doncaster, Selby, Howden and Brough.
- Going North from London King’s Cross to Sheffield, trains call at Retford, Worksop and Woodhouse.
There are only a small number of stops on the Sheffield service. Is this to reduce the journey time as much as possible?
What Will Be The Time Of The London King’s Cross And Sheffield Service?
Consider.
- Non-stop trains take 82 minutes between London King’s Cross and Retford, which is 138.6 miles, so it’s an average speed of 101.4 mph.
- Woolmer Green and Retford are 111.7 miles and will in a couple of years, be digitally signalled.
- Non-stop trains take 66 minutes between Woolmer Green and Retford, which is an average speed of 112 mph.
- I have found a direct Retford and Sheffield train, that takes 31 minutes for the 23.5 miles with six stops, which is an average speed of 45 mph.
- The Retford and Sheffield section has a mostly 60 mph maximum speed.
I can now build a table of times between King’s Cross and Retford based on the average speed North of Woolmer Green.
- 125 mph – 72 minutes
- 130 mph – 70 minutes
- 135 mph – 68 minutes
- 140 mph – 66 minutes
Note.
- Getting a high average speed using the power of digital signalling can save several minutes.
- I have measured an InterCity 125 averaging 125 mph on that section.
I can now build a table of times between Retford and Sheffield based on the average speed.
- 45 mph – 31 minutes
- 50 mph – 28 minutes
- 60 mph – 24 minutes
- 70 mph – 20 minutes
- 80 mph – 18 minutes
Note.
- The planned service is expected to stop only twice after Retford, so if we take off two minutes for each of the four stops not taken, this could reduce the time between Retford and Sheffield by 8 minutes.
- There will be a couple of minutes to add for the stop at Retford.
- I feel a typical journey with 125 mph to Retford, 50 mph to Sheffield, could take 94 minutes
- Currently, the fastest London St. Pancras to Sheffield take around 116-118 minutes.
Hull Trains new service could save 22-24 minutes on the current service.
I also feel a fast journey could involve 130 mph to Retford, 60 mph to Sheffield, could take 88 minutes.
Hull Trains new service could save a few minutes over half-an-hour.
Could The Time Of The London King’s Cross And Sheffield Service Be Under 90 Minutes?
I reckon the following is possible.
- After the digital signalling is completed between King’s Cross and Retford, I suspect that a 135 mph average speed can be maintained between Woolmer Green and Retford. This would mean that a King’s Cross and Retford time of 68 minutes would be possible.
- If Network Rail improve the track between Retford and Sheffield, I believe that a 70 mph average could be achieved on the Retford and Sheffield section. This would mean that a Retford and Sheffield time of 20 minutes would be possible.
- I would expect at least six minutes would be saved by missing stops.
This gives a time of 82 minutes between London King’s Cross and Sheffield.
In Anxiety Over HS2 Eastern Leg Future, I said that High Speed Two’s promised London and Sheffield time via a dedicated track would be 87 minutes.
It looks to me that running under full digital signalling on the East Coast Main Line, Hull Trains can beat the HS2 time.
Could Hitachi’s Battery-Electric Trains Handle The Routes?
This page on the Hitachi web site is entitled Intercity Battery Trains.
This is the sub-heading
Accelerate the decarbonisation of intercity rail with batteries.
These paragraphs outline the philosophy of the design of the trains.
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.
Wouldn’t it be great, if we could take the diesel engine out of our cars and replace it with an electric power pack?
Paul Daniels would’ve classed it as engineering magic.
But it’s an old engineer’s trick.
As a fifteen year old, I spent time in a rolling mill, building and fitting replacement control systems on large machines. Transistors were used to replace electronic valves and relays.
It’s certainly possible to create a battery pack, that is plug-compatible with an existing diesel generator, that responds to the same control inputs and gives the same outputs.
At the extreme end of this technology, there would be no need to change any of the train’s software.
In The Data Sheet For Hitachi Battery Electric Trains, these were my conclusions for the performance.
- The battery pack has a capacity of 750 kWh.
- A five-car train needs three battery-packs to travel 100 miles.
- A nine-car train needs five battery-packs to travel 100 miles.
- The maximum range of a five-car train with three batteries is 117 miles.
- The maximum range of a nine-car train with five batteries is 121 miles.
As the East Coast Main Line to Beverley is a round trip is 88.6 miles, I suspect that Hull Trains’s five-car Class 802 trains will need to be fitted with a full-complement of three batteries.
Will Hull Trains Have An Identical Fleet Of Trains?
An identical fleet must have advantages for train staff, maintenance staff and above all passengers.
I believe FirstGroup have two choices.
- They buy an appropriately-sized batch of identical Class 802 trains.
- They convert their current fleet to battery-electric operation and buy an appropriately-sized batch of identical new trains.
Note.
- The second option means that they fully-decarbonise Hull Trains.
- Neither option would need any new infrastructure.
- I feel this means that this order is more likely to go to Hitachi.
It’ll probably all come down to the accountants.
Retford Station
This OpenRailwayMap shows the tracks around Retford station.
Note.
- The red tracks are electrified and are the East Coast Main Line.
- The black ones aren’t electrified.
- Doncaster is to the North.
- The black line to the East goes to Lincoln
- The black line to the West goes to Sheffield
- The red line going South-East goes to Peterborough and London.
The unusual loop allows trains to connect from one direction to another.
This second OpenRailwayMap shows the tracks in more detail.
Note.
- As before red lines are electrified and black ones aren’t
- Platforms 1 and 2 are on the East Coast Main Line.
- Platforms 3 and 4 are on the Sheffield and Lincoln Line.
This third OpenRailwayMap shows the platforms in more detail.
Note.
- The yellow tracks are the 125 mph fast lines of the East Coast Main Line.
- The light blue tracks are the 40 mph relief lines of the East Coast Main Line.
- Northbound tracks are to the left of each pair of lines.
- The dark blue track is the 10 mph chord that connects the Northbound relief line of the East Coast Main Line to the Sheffield and Lincoln Line.
- Platform 1 is on the Southbound relief line.
- Platform 2 is on the Northbound relief line.
- Unusually, both platforms are on the same side of the line.
- In The Lengths Of Hitachi Class 800/801/802 Trains, I state that the full length of an InterCity 225 train is 245.2 metres.
- I suspect that both platforms can accommodate a full length InterCity 225, as the trains have been calling at Retford since the 1980s.
I doubt Retford station has any problem accommodating a pair of Class 802 trains, which it does regularly.
How Do Northbound Trains Go To Sheffield From Retford Station?
This OpenRailwayMap shows the tracks to the South of Retford station in detail.
Note.
- The yellow tracks are the 125 mph fast lines of the East Coast Main Line.
- The light blue tracks are the 40 mph relief lines of the East Coast Main Line.
- Northbound tracks are to the left of each pair of lines.
Trains needing to stop in Retford station will need to cross to the Northbound relief line to enter Platform 2 at Retford station.
This OpenRailwayMap shows the curve that connects Platform 2 at Retford station to the Sheffield and Lincoln Line to Sheffield.
Note.
- The green tracks are the 60 mph Sheffield and Lincoln Line.
- Sheffield is to the West.
- The blue tracks are the curve that connects Platform 2 in Retford station to the Sheffield and Lincoln Line.
- There appears to be a grade-separated junction, where the two lines join to the West of Retford station.
A Northbound train to Sheffield will take curve and then join the line to Sheffield.
How Do Southbound Trains Go From Sheffield Through Retford Station?
I suspect trains do the opposite from a train going to Sheffield.
The train takes the curve and then stops in Platform 2 facing South.
This OpenRailwayMap shows the tracks to the South of Retford station in detail.
When the train is cleared by the signals to go South, it will leave Retford station going South on the Northbound relief line.
Note that on the map there are two crossovers, which the train will take to get on the Southbound fast line for Newark and London.
As a Control Engineer, I suspect this is the sort of manoeuvre, that modern digital signalling will make slicker and safer.
How Do Northbound Trains Go To Hull From Retford Station?
On leaving the station, the train will continue along the relief line until it merges with the Northbound fast line for Doncaster.
This is exactly as any Northbound train stopping at Retford does now.
How Do Southbound Trains Go From Hull Through Retford Station?
Currently, trains from Hull stop in Platform 1 on their way to London.
- Trains needing to stop in Retford station will need to cross to the Southbound relief line to enter Platform 1 at Retford station.
- When the train is cleared by the signals to go South, it will leave Retford station going South on the Southbound relief line.
- The Southbound relief line joins the Southbound fast line to the South of the station.
This is exactly as any Southbound train stopping at Retford does now.
Could A Hull And A Sheffield Service Run As A Pair And Split And Join At Retford Station?
Consider.
- Class 802 trains, as used by Hull Trains are designed to be run as a pair of trains, with easy coupling and uncoupling between the two trains.
- Hull Trains regularly run services as a pair of Class 802 trains.
- A pair of trains could leave King’s Cross. They would then split at a convenient station, after which the two trains go to different destinations.
- There are advantages with respect to infrastructure charges.
I feel that Hull Trains two services to Sheffield and Hull/Beverley could work as a pair.
- A pair of trains could leave King’s Cross.
- At Retford station they would split, with one train going to Hull and the other to Sheffield.
Coming South they would join at Retford.
How Would Splitting Of A Hull And Sheffield Service Be Performed At Retford Station?
The procedure would be something like this.
- As the pair of train is stopping in Retford station, it would use the relief line to enter Platform 2.
- It would stop in Platform 2.
- The trains would be uncoupled.
- The front train would go to its destination.
- The rear train would go to its destination.
Note.
- As the track to Doncaster and Hull is faster, the front train should probably be for Hull.
- Platform 2 is electrified, so the Sheffield train could top up its batteries .
- The Sheffield train could lower its pantograph.
Uncoupling takes about two minutes.
How Would Joining Of A Hull And Sheffield Service Be Performed At Retford Station?
Consider.
- Joining would have to be performed in Platform 2, as there is no route for a train from Sheffield to access Platform 1.
- North of Retford station there are two convenient crossovers, to allow a train to cross to the Northbound relief line. There are also a couple of loops, where trains could wait.
- As this is coal-mining country, perhaps, they were part of a freight route between Sheffield and Doncaster?
But this infrastructure would allow, a train from Hull to access Platform 2 at Retford station.
As the Sheffield train can easily access Platform 2, the two trains could meet in Platform 2 and then be joined together for a run to London.
Is There A Problem With Splitting And Joining Of the Hull And Sheffield Services?
Earlier, I said these were the stops of the two services.
- Going North from London King’s Cross to Hull, trains call at Stevenage (limited), Grantham, Retford, Doncaster, Selby, Howden and Brough.
- Going North from London King’s Cross to Sheffield, trains call at Retford, Worksop and Woodhouse.
Surely, if the trains were travelling as a pair, they would need to stop at the same stations to the South of Retford.
But modern digital signalling will allow trains to run closer together, so perhaps this would be the procedure going North.
- The two trains start in the same platform at King’s Cross, with the Sheffield train in front of the Hull train.
- The two trains leave King’s Cross a safe number of minutes apart.
- At its Stevenage and Grantham stops, the Hull train will tend to increase the distance between the two trains.
- The Sheffield train would stop in Platform 2 at Retford station, so that space is left for the Hull train.
- The Hull train will stop behind the Sheffield train in Platform 2 at Retford station.
- The Sheffield train will leave when ready.
- The Hull train will leave when ready.
And this would be the procedure going South.
- The train from Sheffield would line up in Platform 2 at Retford station.
- The train from Hull would line up in Platform 1 at Retford station.
- The train from Sheffield would leave when everything is ready and the train is cleared by the signalling system.
- The train from Hull would leave a safe number of minutes behind the train from Sheffield.
- At its Grantham and Stevenage stops, the Hull train will tend to increase the distance between the two trains.
- The trains could share a platform at King’s Cross.
The digital signalling and the driver’s Mark 1 eyeballs will keep the Hull train, a safe distance behind the faster Sheffield train.
The Capacity Of The Lincoln And Sheffield Line
Looking at the Sheffield and Lincoln Line, it has only an hourly train, that calls at Darnall, Woodhouse, Kiverton Park, Kiverton Bridge, Shireoaks and Worksop between Retford and Sheffield.
- I would suspect that there is enough spare capacity for Hull Trains to run a one train per two hours (tp2h) service between London King’s Cross and Sheffield.
- If LNER feel that a 1 tp2h frequency is viable for Harrogate, Lincoln and other places, surely Hull and East Sheffield could support a similar service from King’s Cross.
If the services could be run by battery-electric trains, capable of running at 140 mph on the East Coast Main Line and giving times of ninety minutes to Sheffield, this could be a success.
Could Woodhouse Station Become A Transport Hub?
This Google Map shows Woodhouse station.
Note.
- It is certainly surrounded by a lot of houses.
- Could it be provided with car-parking?
Although, as this picture shows it is not blessed with lots of facilities.
But.
- The station is in an area, which Sheffield want to develop.
- The Advanced Manufacturing Centre is nearby.
- There are aspirations to run a tram-train between Sheffield and Chesterfield via Darnall, Woodhouse and Barrow Hill stations.
- The station could be on the tram-train route to Stocksbridge, that I wrote about in Reopening The Don Valley Section Of The Former Woodhead Line Between Stocksbridge and Sheffield Victoria To Passenger Services.
Woodhouse station could be an interchange or it could become something bigger like a hub station.
How Many Sheffield Services Per Day Could Be Run?
If the Hull and Sheffield trains run as a flight under control of the digital signalling, this will mean that every Hull train can be paired with a Sheffield train.
- There are five trains per day (tpd) to and from Hull and two to and from Beverley.
- It seems a maximum of one tpd in both directions can be a ten-car train.
- Two five-car trains could fit in a platform at King’s Cross.
I suspect that the maximum number of trains per day to and from Sheffield is the same as for Hull. i.e. seven tpd.
But there is no reason, if they have enough trains and paths are available, that Hull Trains couldn’t add extra services to both destinations.
Onward From Sheffield
Several of those, who have commented on the new service have suggested that the service could go further than Sheffield, with Manchester and Leeds being given specific mentions.
This OpenRailwayMap shows the platforms at the Northern end of Sheffield station.
Note.
- The pink tracks at the East are the Sheffield Supertram.
- Trains to and from Barnsley, Huddersfield, Hull, Leeds, Lincoln and Retford access the station from the Northern end.
- Trains to and from Chesterfield, Derby, London, Manchester and Stockport access the station from the Southern end.
- The tracks in Sheffield station are numbered 1 to 8 from the West.
- There are five through platforms. 1, 2, 5, 6 and 8 and two bay platforms at either end.
- An extension of the service to Manchester via the Hope Valley Line, could go straight through the station.
- An extension of the service to Barnsley, Huddersfield or Leeds, would mean the train reversing at Sheffield.
It looks like an extension to Manchester Piccadilly over the recently upgraded Hope Valley Line would be the easiest extension. But would Avanti West Coast, who have FirstGroup as a shareholder want the competition?
Recently, it has been announced that the Penistone Line to Barnsley and Huddersfield will be upgraded to accept two trains per hour (tph) and allow faster running.
Because Sheffield could be around eighty minutes from London, there could be some smart times to and from the capital.
- Meadowhall in 90 minutes
- Barnsley in 112 minutes.
- Huddersfield in 140 minutes.
Huddersfield could be almost twenty minutes faster than the route via Leeds.
Comments From The Times
These are some readers comments from The Times.
- Hope the prices are competitive with LNER. I rarely go to London from Chesterfield with EMR as they’re so expensive. LNER from Newark is much cheaper but a service from Worksop for me would be perfect.
- Excellent News in so many ways. I hope it really takes off which could help ease the congestion on the M1 and also thin out overcrowding on busy LNER services. It really does deserve to succeed.
- This is excellent news. The Lumo service has been a game changer for me and those living in the north east.
The public seem in favour.
Conclusion
I really like this proposal from FirstGroup.
- It has the possibility to provide Sheffield with a fast train link to London.
- It could run about six trains per day.
- It will be faster than High Speed Two was proposed.
It could be the first service of High Speed Yorkshire.
Alaska Airlines Grounds 737 Max 9 Planes After Section Blows Out Mid-Air
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A passenger plane lost a section of its fuselage in mid-air forcing it to make an emergency landing in the US state of Oregon.
Theses three paragraphs outline what happened.
The Alaska Airlines Boeing 737 Max 9 turned back 35 minutes into its flight to California after an outer section, including a window, fell off on Friday.
There were 177 passengers and crew on board and it landed safely in Portland.
The airline said it would temporarily ground all 65 of its 737 Max 9 aircraft to conduct inspections.
I think it is true to say that everybody was very lucky.
When I was a private pilot flying around the UK, Europe and Australia, I used to read the accident reports and I suspect there was a couple of structural failures like this, that had a much worse outcome.
These are two paragraphs from the BBC article.
In an audio clip, the pilot can be heard talking to air traffic control requesting a diversion.
“We are an emergency,” she said. “We are depressurised, we do need to return back.”
Strangely, this is the first airline incident or accident, I can remember, where the pilot was female. But there must have been others.
One of the genuine firsts, I have been involved in, was Air UK’s first flight with an all-female crew.It was probably in the 1980s and my late wife; C and myself flew from Stansted to Paris in a Short 360.
Conclusion
I would fly with a female pilot any time, but I doubt you’ll catch me in a Boeing 737!
Japanese Offshore Wind And Battery Storage Project Begins Commercial Operation
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
On 1 January 2024, JERA and Green Power Investment Corporation (GPI) began commercial operations at the 112 MW Ishikari Bay New Port Offshore Wind Farm in Japan, which they own through Green Power Ishikari GK, a special-purpose corporation (SPC).
The most significant thing about this wind farm, is that it has been designed from Day One to operate with a battery, which is detailed in the last paragraph.
The project also features a battery storage component with 100 MW x 180 MWh of capacity.
Note that the output of the battery is 89 % of that of the wind farm. Is that the ideal ratio between battery and wind farm capacities?
Conclusion
Because of my training, as an Electronics and Control Engineer, I belief that most renewable energy can be smoothed with the adding of a battery.
Sadiq Khan ‘Is Waging War On Motorists To Plug The £15 Billion Blackhole In TfL Finances’
The title of this post, is the same as that of this article on London Loves Business.
These are the first three paragraphs.
Sadiq Khan plans to raise at least £123 million per year by charging motorists to drive through the Blackwall and Silvertown tunnels.
In a written response to a question from City Hall Conservatives, the Mayor said tolls would be introduced on both tunnels when the new Silvertown Tunnel opens in 2025.
The Mayor said Transport for London (TfL) would receive revenue from the new tolls and penalty notices, less the cost of annual construction repayments and maintenance fees. The Mayor, who is chairman of TfL, has previously said he expects tolls and penalties to ‘more than cover’ these annual costs.
I don’t drive, so the cost of using the tunnels, has no effect on my finances.
This document from TfL says this about car usage in London.
London residents aged 16+ make 4.6m car driver trips and 1.4m car passenger trips
on an average day, of which 3.7m are within London, with the remainder involving
travel to and from London. Non-residents make around 1 million car journeys a day
to, from or within London.
It does look that London has a lot of car drivers and passengers.
Surely, out of common decency, the toll for using the Blackwall and Silvertown tunnels, should be disclosed by Sadiq Khan before the London Mayor Election later this year.
Or is he frightened, that the size of the toll will lose him votes?
Potato Waste Used In New Hydrogen Production Research In P.E.I.
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This is the sub-heading.
UPEI researchers are looking for new ways to produce hydrogen.
These are the first three paragraphs.
University of Prince Edward Island (UPEI) researchers have cooked up new hydrogen production recipes that include waste products like potato peelings, sawdust and tunicate.
An assistant professor in the Faculty of Sustainable Design Engineering at UPEI, Yulin Hu is one of a group of researchers seeking novel ways to generate hydrogen to replace fossil fuels and combat the effects of climate change.
One hydrogen production research project is focused on extracting H2 from potato peelings. The potato waste idea is especially notable due to Prince Edward Island (P.E.I.) being the Canadian province known for its potatoes.
Note.
Do the Canadians get their King Edwards from Prince Edward Island?
The potato is named after Edward VII according to its Wikipedia entry.
Tunicates are marine invertebrates.
This paragraph summarises some of the research.
The project involving sawdust is looking at utilizing sawdust to capture carbon dioxide. As for the one focused on tunicate, the idea behind that project is to synthesize tunicate waste, taking the waste and converting it into bio fertilizer.
The Canadian government must be impressed as they have given a six-figure grant for the research.
Conclusion
There’s some wacky research out there and some of it might be worth pursuing.
Aker Solutions To Pilot Floating-Wind Power Hub
The title of this post, is the same as that of this press release from Aker Solutions.
This is the sub-heading.
Aker Solutions to pilot world’s first subsea power distribution system for floating offshore wind at Norway´s METCentre
These four paragraphs describe the system and explain how it works.
Note.
Aker Solutions has signed a front-end engineering and design (FEED) contract with the Marine Energy Test Centre (METCentre) in Norway to pilot new subsea power system technology which has the potential to significantly reduce the costs and complexity of offshore wind farms.
The project will see Aker Solutions provide new power transmission technology, Subsea Collector, for the METCentre’s offshore wind test area which today consists of two floating offshore wind turbines located 10 kilometers off the southwestern coast of Karmøy, Norway. The test area will expand to seven floating offshore wind turbines from 2026.
Subsea Collector provides an alternative solution to connect multiple wind turbines electrically in a star configuration instead of the traditional daisy chain pattern, allowing for more flexibility in offshore wind farm architecture and construction. The design also allows for reduced cable length per turbine and park, as well as less vessel time and installation costs. Initial findings support total cost savings on a 1GW floating wind farm of up to 10 percent.
The main component parts of the Subsea Collector comprise a 66kV wet mate connection system provided by Benestad and subsea switchgear with supervisory control and data acquisition by subsea power and automation alliance partner, ABB. Installation will be carried out by Windstaller Alliance, an alliance between Aker Solutions, DeepOcean and Solstad Offshore. Aker Solutions will also provide the static export cable to shore.
Total cost savings of ten percent on any large project are not to be sneezed at.
I also feel that this sort of architecture will be ideal for a test centre, where configurations are probably changed more often.
Offshore Wind Turbines In 2023: 16 MW Model Installed Offshore, 18 MW WTGs Selected For New Project, 22 MW Turbine Announced
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The biggest wind turbines also make for some of the biggest news on offshoreWIND.biz. In 2023, wind turbine OEMs continued making headlines with their models in development and on the path to commercialisation, and by announcing brand new wind turbine generators (WTGs) that further raise the bar in generation capacity and size. Here, we are bringing an overview of the biggest and most powerful wind turbines we reported about in 2023.
This is the first paragraph.
Some of the wind turbines from our lookback article from a year ago, which were announced or launched in 2022, have now advanced to being installed offshore and/or are already being selected for commercial offshore wind projects that are planned to be built in the not-so-distant future.
Offshore wind turbines are certainly getting larger.
- The Chinese seem to be leading the way with turbines that produce over 20 MW, but European and US manufacturers appear to be looking at 16-18 MW.
- This compares with typical farms commissioned in the last few years of about 13-14 MW, which is roughly a 26 % increase in size.
- In Crown Estate Mulls Adding 4 GW Of Capacity From Existing Offshore Wind Projects, I talk about how bigger turbine sizes could be increased in wind farms, that are being planned.
I feel the UK, could benefit from this increase in wind turbine size.
New LNER Fleet To Have Joint Line Capability
The title of this post, is the same as that of an article in the January 2024 edition of Modern Railways.
This is the text of the article.
LNER’s new fleet of CAF tri-mode trains, for which an order was confirmed in November, has been specified with the capability to operate via the Joint Line via Spalding and Lincoln in case of closures on the East Coast Main Line between Peterborough and Doncaster.
CAF will supply 10×10-car trains with overhead electric, battery and diesel capability, financed by Porterbrook. The inclusion of diesel engines as part of the winning bid, rather than a straightforward battery-electric unit, has surprised some observers, but LNER’s specification was that the fleet should have sufficient self-powered capability to cover the length of the joint line, which is approximately 90 miles. This is currently to be considered to be beyond the scope of battery-power alone, although as the technology evolves diesel engines could be replaced by batteries. The configuration of diesel engines and batteries within the sets has yet to be decided.
LNER frequently uses the Joint Line as a diversionary route, both during planned engineering work and at times of disruption, but only its bi-mode Azumas are currently able to traverse it under their own power (electric sets have been hauled by a diesel locomotive, but this is now a very rare occurrence). The new CAF fleet will replace the InterCity 225 electric fleet, and the self-power capability will provide valuable resilience to LNER to divert via non-electrified routes.
While the ‘225s’ are currently confined to services between King’s Cross and Leeds/York, if the enhanced December 2024 timetable goes ahead as currently planned (see story above) they will operate north of York once again on some of the hourly services which will terminate at Newcastle. However, LNER is having to limit the use of the sets before the Class 91 locomotives and Mk 4 coaches come due for major overhauls: the decision to retain 12 locos and eight rakes of coaches was based on the intended timescale for replacing the fleet at the time, but confirming the order for the new CAF tri-modes has taken longer than anticipated, largely due to delays in receiving Government approval to place the order.
This article has got me thinking.
The InterCity225 Trains Need Replacing Urgently
The Modern Railways article states that the need to replace the InterCity 225s is getting urgent, as more than the Azumas will be needed for the December 2024 timetable and the InterCity 225s are getting to the end of their economic life.
As LNER have been doing reasonably well lately, a cock-up caused by lack of trains at Christmas 2024 would be the last thing they need.
Currently, LNER have enough Mark 4 coaches for eight trains, so ordering ten new CAF tri-mode trains will allow for a small amount of extra services.
The CAF tri-mode trains were only ordered in November 2023, so getting them delivered for December 2024 would be tight.
As I write this on the 31st December 2023, trains from King’s Cross to Leeds included.
- 5 x InterCity225
- 5 x 10-car Azuma
- 7 x 9-car Azuma
- 2 x 5-car Azuma
So there were InterCity 225s running on that day.
A Few Distances Around Lincolnshire
I believe that because of offshore wind, interconnectors and other renewable energy developments, that Lincolnshire will become an energy powerhouse, supporting the East Midlands and also exporting electricity and hydrogen to Europe through pipelines and interconnectors.
Because of this and other developments, I believe that rail passenger traffic to and around the county will increase significantly.
These are a few selected distances.
- Doncaster and Cleethorpes – 52.1 miles
- Grantham and Skegness – 58.2 miles
- Lincoln and Doncaster – 36.8 miles
- Lincoln and Newark – 16.8 miles
- Lincoln and Peterborough – 54.8 miles
- Lincoln and Cleethorpes – 47.2 miles
Note.
- This means that the length of the Joint Line, which between Werrington Junction and where it rejoins the East Coast Main Line to the South of Doncaster is no more than ninety miles. This ninety mile distance was assumed in the Modern Railways article.
- Peterborough and Cleethorpes via Lincoln is ninety-two miles.
- I estimate that around four miles could be easily electrified at Werrington, which would reduce these two distances by four miles.
- Newark and Cleethorpes via Lincoln is sixty-four miles.
It looks like if a battery-electric train had a range of 92 miles and there was charging at Cleethorpes and Skegness, Lincolnshire could have a first class zero-carbon rail service.
CAF Tri-Mode Trains And The Joint Line
This is the first sentence in the Modern Railways article.
LNER’s new fleet of CAF tri-mode trains, for which an order was confirmed in November, has been specified with the capability to operate via the Joint Line via Spalding and Lincoln in case of closures on the East Coast Main Line between Peterborough and Doncaster.
Note.
- The Modern Railways article states the Joint Line is approximately 90 miles.
- As I stated earlier with some strategically placed electrification at Werrington and South of Doncaster, this distance without electrification can probably be shortened by a few miles.
It looks like any service run by a CAF tri-mode train will be able to use the Joint Line.
Hitachi Class 801 Trains And The Joint Line
Unless the Joint Line is electrified or the all-electric Class 801 trains are fitted with batteries of a sufficient size the Class 801 trains will not be able to use the Joint Line.
Hitachi Class 800/802 Trains And The Joint Line
If currently, the Class 800/802 trains can handle the Joint Line on their diesel engines, they can continue to do this.
Hitachi Class 803 Trains And The Joint Line
Unless the Joint Line is electrified or Class 803 trains are fitted with batteries of a sufficient size the Class 803 trains will not be able to use the Joint Line.
Hitachi Class 80x Trains With Batteries And The Joint Line
Note that Lumo’s Class 803 trains are already fitted with an emergency battery for hotel power. So Hitachi must have information on how their batteries perform in service.
This press release from Hitachi, which is entitled Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20% announced the start of Hitachi’s battery-electric program in December 2020.
This is a paragraph.
The projected improvements in battery technology – particularly in power output and charge – create opportunities to replace incrementally more diesel engines on long distance trains. With the ambition to create a fully electric-battery intercity train – that can travel the full journey between London and Penzance – by the late 2040s, in line with the UK’s 2050 net zero emissions target.
Hitachi have now published this page on their web site, which is entitled Intercity Battery Trains.
The page has this sub-heading.
Accelerate the decarbonisation of intercity rail with batteries
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 appears to be a masterful application of an old electrical or software engineer’s trick.
In the 1960s, I spent time in two summer holidays building transistorised control systems in a rolling mills to replace obsolete control systems that used thermionic valves and relays.
Are Hitachi just replacing a diesel power pack with a battery pack, that has the same power and control functionality?
In The Data Sheet For Hitachi Battery Electric Trains, I looked at Hitachi’s published data sheet, which has these bullet points.
- 750kW peak power
- Weight neutral
- At least 20% lower CO2 emissions
- 70km on non-electrified routes
- 20% reduction in whole life maintenance costs
- Up to 30% fuel cost savings
- Zero emissions in and out of stations
- Charge on the move
- 10 year life span
Note.
- 750 kW peak power, is around the power of the diesel-engine, that will be replaced.
- I wouldn’t be surprised that powerwise, the battery pack looks like a diesel engine.
- Weight neutral means that acceleration and performance will be unchanged. I suspect this means that current timetables can be achieved.
- Batteries are easier to maintain than diesels.
- It is stated that a train can be fully-decarbonised.
I have a feeling these trains are no ordinary battery-electric trains.
This paragraph, that I quoted earlier gives details on battery range.
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.
If one battery can give seventy kilometres or 43.5 miles, what distances would be possible in the various Hitachi Class 80x trains on the UK rail network?
- Five-car Class 800 – Three diesel engines
- Nine-car Class 800 – Five diesel engines
- Five-car Class 801 – One diesel engine
- Nine-car Class 801 – One diesel engine
- Five-car Class 802 – Three diesel engines
- Nine-car Class 802 – Five diesel engines
- Five-car Class 803 – One battery
- Five-car Class 805 – Three diesel engines
- Seven-car Class 807 – No diesel engine or battery
- Five-car Class 810 – Four diesel engines
Note.
- The Class 801 trains have one diesel engine for emergency use.
- The Class 803 trains have one battery for emergency use.
- The Class 807 trains appear to be built for top speed and acceleration and have no unnecessary weight.
In The Data Sheet For Hitachi Battery Electric Trains, I came to the conclusion, that if all diesel engine packs are be replaced by batteries, the train has a range of around 117-121 miles.
If my calculation is correct, I believe that Hitachi battery-electric trains will be capable of using the Joint Line, if all diesel engines are replaced by battery packs.
Surely, if a number of Hitachi trains could use the Joint Line in addition to the ten CAF tri-mode trains, this would minimise disruption to passengers and increase revenue on days, when the East Coast Main Line was closed for engineering works or an incident.
Will The Hitachi Class 80x Trains With Batteries Or The CAF Tri-Mode Trains Have The Longer Range Without Electrification?
Consider.
- Cleethorpes could be the problem, as it is 64 miles from Newark and 92 miles from Peterborough and a round trip without charging at Cleethorpes for a battery-electric might be a trip to far.
- But a tri-mode train like that from CAF with an on-board diesel, should have the range.
- More range for a tri-mode train, just needs bigger fuel tanks.
- I also suspect Cleethorpes has the equipment to refuel a diesel train, as all services to the station are diesel powered.
The article also says this.
The inclusion of diesel engines as part of the winning bid, rather than a straightforward battery-electric unit, has surprised some observers, but LNER’s specification was that the fleet should have sufficient self-powered capability to cover the length of the joint line, which is approximately 90 miles. This is currently to be considered to be beyond the scope of battery-power alone, although as the technology evolves diesel engines could be replaced by batteries.
Could it be that some of LNER’s routes like Aberdeen, Cleethorpes and Inverness have longer running without electrification, than Hitachi’s trains with batteries can achieve. Perhaps, this is why they lost the order?
Pairs Of Hitachi Class 80x Trains With Batteries And The Joint Line
I suspect if one five-car train with batteries can handle the Joint Line, then a pair could also handle it, if the train’s control system allowed it.
Will The Joint Line Be Slower Than The East Coast Main Line?
Consider.
- The Joint Line is not the slowest line in the country and large sections of the route, have a top speed of 60 mph or higher.
- It is surprisingly straight.
- There are some slower sections, through Lincoln and Sleaford.
- The average speed between Peterborough and Lincoln of local trains is about 50 mph.
- The average speed between Doncaster and Lincoln of local trains is about 48 mph.
I suspect that the expresses, should be able to achieve 60 mph between Peterborough and Doncaster, with a small amount of track improvement.
This would mean the following times between Doncaster and Peterborough.
- Via the Joint Line – 90 minutes
- Via East Coast Main Line – 50 minutes
It looks like forty minutes will be added to journey times.
Would There Be Any Point In Running Some Services Via The Joint Line?
Consider.
- Lincoln has one train per two hours (tp2h) to and from King’s Cross.
- A King’s Cross and Doncaster service could use the Joint Line and call at Peterborough, Spalding, Sleaford, Lincoln Central, Gainsborough Lea Road and Doncaster.
- If it terminated at Harrogate, Leeds or York, it could ease congestion on the East Coast Main Line between Peterborough and Doncaster.
- Lincoln is making a name for itself as a University town.
- Lincolnshire is getting more important with respect to renewable energy and innovative food production.
- The frequency would be at least one tp2h.
- If needed, Lincoln Central could be electrified to charge passing trains.
- The service could also go via Cambridge to provide East Anglia and its technological powerhouse with better connections to and from the North.
It would all depend on where extra rail services are needed.
Could Cleethorpes And Grimsby Town Have A Service From King’s Cross?
In Azuma Test Train Takes To The Tracks As LNER Trials Possible New Route, I discuss how in June 2023, LNER ran a test train to Cleethorpes and Grimsby Town.
- With all the energy development going on in North-East Lincolnshire, I suspect that a service between King’s Cross and Cleethorpes via Lincoln, Market Rasen, Barnetby and Grimsby Town could be viable.
- I suspect that the energy developments could find recruitment difficult and say a one tp2h service to Peterborough might ease the problem.
- Whether it ran to Lincoln via Newark and the East Coast Main Line or via Spalding and Sleaford would be down to predicted traffic.
- The distance via Newark would be 64 miles or 128 miles return.
- The distance via Peterborough would be 92 miles or 184 miles return.
- These distances would probably mean that a battery-electric train would need charging at Cleethorpes.
So would it be better if the Cleethorpes trains were to be run by CAF tri-mode trains.
Could Cleethorpes Services Be Paired With The York Service?
The current King’s Cross and Lincoln service uses the same path as a York service.
- Both services leave King’s Cross at six minutes past the hour.
- York trains leave at odd hours.
- Lincoln trains leave at even hours.
If the York service used the Joint Line and the Lincoln service were to be extended to Cleethorpes, Lincoln would receive an hourly service.
- One service could go via Newark and the other via Peterborough, Spalding and Sleaford.
- A path on the East Coast Main Line would be saved.
- The service to York could go via Leeds.
- The York service could be extended to Middlesbrough, Scarborough or Sunderland.
- I suspect that timings to Cleethorpes and York could be a similar six-hour round trip.
- CAF tri-mode trains would be needed for the Cleethorpes services.
- Either train type could work the York services.
There are various possibilities to improve the train service been London and Lincolnshire.
What Will Be The Maximum Range Of The CAF Tri-Mode Trains?
When determining this, LNER would probably have taken into account all current and every possible service, that they might run in the future, which was not fully electrified.
These would include.
- London King’s Cross and Aberdeen – 91.4 miles
- London King’s Cross and Bradford Interchange via Shaftholme junction – 47.8 miles
- London King’s Cross and Cleethorpes via Newark and Lincoln – 64 miles
- London King’s Cross and Cleethorpes via Peterborough, Spalding and Lincoln – 92 miles
- London King’s Cross and Harrogate via Leeds – 18.3 miles
- London King’s Cross and Inverness– 151.1 miles
- London King’s Cross and Hull via Temple Hirst junction – 36.1 miles
- London King’s Cross and Lincoln – 16.8 miles
- London King’s Cross and Middlesbrough via Northallerton – 20.3 miles
- London King’s Cross and Scarborough via York – 42.1 miles
- London King’s Cross and Sunderland via Northallerton – 47.4 miles
They would also have taken in possible diversion routes.
- London King’s Cross and Carlisle via Leeds – 86.8 miles
- London and Edinburgh – 400 miles
- London King’s Cross and Newcastle via Northallerton and Durham Coast Line – 59.6 miles
Note.
- The distance is the length without electrification.
- London King’s Cross and Carlisle is a possible diversion route, if between Leeds and Edinburgh is blocked.
- A London King’s Cross and Edinburgh capability might be needed, if there was something like a serious weather problem, bringing down the overhead wires.
- London King’s Cross and Newcastle via Northallerton and Durham Coast Line is a possible diversion route, if between Northallerton and Newcastle is blocked.
LNER’s longest route without electrification is to Inverness and it is 151.1 miles between Stirling and Inverness.
London King’s Cross and Cleethorpes via Peterborough, Spalding and Lincoln could be longer, if it were to be run as a return trip of 184 miles.
LNER will probably have specified the range they need on the longest route they run or might run in the future, as there is no point in buying a fleet of trains and then finding that they can’t handle all your routes. They would also include all possible emergency routes, just as they’ve already included the Joint Line.
Out of curiosity I asked Professor Google how far a diesel train could run on a full tank of diesel and got this answer.
According to the traction manual for 158/159 stock each coach has a 400 gallon tank or 1818 Ltr. £2500 at the filling station.
The manual also says that that is enough fuel to travel Waterloo to Exeter and back twice over. Which is 688 miles exactly. Guess there is spare in there for shunting and idling at terminus. Still an mpg of 1.7.
It looks to me, that if a humble Class 158/159 train has a range of nearly 700 miles, then LNER can probably have virtually any distance they want for their new trains.
These journeys will probably all be possible.
- Between London King’s Cross and Edinburgh – 400 miles
- A round trip between Stirling and Inverness – 302.2 miles
- A round trip between Peterborough and Cleethorpes – 184 miles
Professor Google also gives the diesel range of a Class 800 train as 650 miles.
Conclusion
It looks to me, that LNER, Lumo and FirstGroup have a serious plan to decarbonise their network.
All services, that can be decarbonised by replacing diesel generator units, with electrical battery packs.
LNER’s longer routes will use the new CAF trains.
These will be fully decarbonised at a later date.
What Will Be The Power Unit In LNER’s New CAF Tri-Mode Trains?
There is a short article in the January 2024 Edition of Modern Railways, that is entitled New LNER Fleet To Have Joint Line Capability.
This is said about the diesel engines in the new CAF tri-mode trains.
CAF will supply 10×10-car trains with overhead electric, battery and diesel capability, financed by Porterbrook. The inclusion of diesel engines as part of the winning bid, rather than a straightforward battery-electric unit, has surprised some observers, but LNER’s specification was that the fleet should have sufficient self-powered capability to cover the length of the joint line, which is approximately 90 miles. This is currently to be considered to be beyond the scope of battery-power alone, although as the technology evolves diesel engines could be replaced by batteries. The configuration of diesel engines and batteries within the sets has yet to be decided.
As the paragraph says that the diesel engines can be replaced by batteries and the trains are from CAF’s modular Civity family, it sounds like CAF are using a modular power system.
The CAF Class 195, 196 and 197 diesel multiple units, that are used in the UK, use mtu Railcar Power Packs, which are shown on this web page.
mtu are a Rolls-Royce subsidiary.
mtu also make a Hybrid Power Pack, which is shown on this web page.
This is the sub-title on the web page.
Individual hybrid drive with a modular design
Underneath is this sub-heading.
It takes revolutionary thinking to develop a smart rail drive system like the Hybrid PowerPack. Find out what makes mtu different, and why our Hybrid PowerPack brings added value to operators while benefiting passengers and the environment alike.
These paragraphs describe the mtu Hybrid PowerPack.
The Hybrid PowerPack was developed from the successful mtu underfloor drives: Tried and tested mtu PowerPacks were modified and equipped with additional components and functionalities in order to integrate hybrid technology. The mtu hybrid concept consists of a modular kit with a variety of drive elements. It satisfies all existing railway standards and can be arranged according to customer specifications.
Thanks to its compact design and the use of power-dense electrical machines, the Hybrid PowerPack can be easily integrated in the existing installation space under the floor, both in new rail vehicles or for repowering. mtu EnergyPacks – the energy storage – can be positioned at various places in the vehicle: on the roof or underfloor. The modular design creates great flexibility for operators who are planning new diesel hybrid vehicles or want to convert existing vehicles.
Based on specifications for the hybrid train and the profile of the planned routes, mtu can simulate the lifecycle costs (capital, maintenance and operating costs) of specific projects. This means that a variety of drive options can be defined even before the design stage. Together with you, we then determine an optimal concept based on your needs.
Note.
- mtu Hybrid PowerPacks can be used in new rail vehicles or for repowering.
- It looks to me, that the total of 161 of Class 195, 196 and 197 trains, that will soon be all in service in the UK may well have been designed to be converted to hybrid power using mtu Hybrid PowerPacks.
- In Would You Buy A Battery Energy Storage System From Rolls-Royce?, I talk about how mtu EnergyPacks are also used for battery storage.
- In fact, mtu EnergyPacks could be the secret ingredient to both systems.
This looks like a typical Rolls-Royce product, that pushes the design to the full.
I will be very surprised if LNER’s new CAF tri-mode trains are not powered by mtu Hybrid PowerPacks.
I have a few thoughts.
CAF Are Going For A Proven Solution
CAF are going for a proven power solution, that they will also need for 161 trains in the UK.
Integration of systems like these can be difficult but CAF are using another company to combine diesel, electric and battery power in an efficient way.
I also feel that mtu Hybrid PowerPacks have a big future and Rolls Royce mtu will do what it takes to make sure they dominate the market.
Decarbonising The Trains
I suspect given Rolls-Royce’s philosophy, that the diesel engines will run on sustainable fuels from delivery.
But as the extract from the Modern Railways article says, the space used by diesel engines can be used for batteries.
Follow The Money
Consider.
- Porterbrook and Rolls-Royce are both based in Derby.
- Porterbrook are a rolling stock leasing company, who own a lot of rolling stock, that could be converted to hybrid trains, using mtu Hybrid PowerPacks.
- Porterbrook are financing LNER’s new CAF tri-mode trains.
I wouldn’t be surprised if Porterbrook and Rolls-Royce have done a lot of due diligence on these trains.
Other Train Operators Will Follow
LNER’s new CAF tri-mode trains may be a bespoke design for LNER, but other train operators will need a similar train.
- CrossCountry need a replacement low-carbon fleet.
- ScotRail need a replacement fleet for their Inter7City services.
- Great Western Railway need a replacement fleet for their GWR Castles.
- Grand Central need a replacement low-carbon fleet.
- TransPennine Express need new trains.
- Open Access Operator Grand Union Trains will need trains.
I think CAF are gong to be busy.
Conclusion
The more I read about Rolls-Royce and its engineering, the more I’m impressed.
