Low Carbon Construction Of Sizewell C Nuclear Power Station
Sizewell C Nuclear Power Station is going to be built on the Suffolk Coast.
Wikipedia says this about the power station’s construction.
The project is expected to commence before 2024, with construction taking between nine and twelve years, depending on developments at the Hinkley Point C nuclear power station, which is also being developed by EDF Energy and which shares major similarities with the Sizewell plant.
It is a massive project and I believe the construction program will be designed to be as low-carbon as possible.
High Speed Two is following the low-carbon route and as an example, this news item on their web site, which is entitled HS2 Completes Largest Ever UK Pour Of Carbon-Reducing Concrete On Euston Station Site, makes all the right noises.
These three paragraphs explain in detail what has been done on the Euston station site.
The team constructing HS2’s new Euston station has undertaken the largest ever UK pour of Earth Friendly Concrete (EFC) – a material that reduces the amount of carbon embedded into the concrete, saving over 76 tonnes of CO2 overall. John F Hunt, working for HS2’s station Construction Partner, Mace Dragados joint venture, completed the 232 m3 concrete pour in early September.
The EFC product, supplied by Capital Concrete, has been used as a foundation slab that will support polymer silos used for future piling works at the north of the Euston station site. Whilst the foundation is temporary, it will be in use for two years, and historically would have been constructed with a more traditional cement-based concrete.
The use of the product on this scale is an important step forward in how new, innovative environmentally sustainable products can be used in construction. It also helps support HS2’s objective of net-zero construction by 2035, and achieve its goal of halving the amount of carbon in the construction of Britain’s new high speed rail line.
Note.
- Ten of these slabs would fill an Olympic swimming pool.
- I first wrote about Earth Friendly Concrete (EFC) in this post called Earth Friendly Concrete.
- EFC is an Australian invention and is based on a geopolymer binder that is made from the chemical activation of two recycled industrial wastes; flyash and slag.
- HS2’s objective of net-zero construction by 2035 is laudable.
- It does appear that this is a trial, but as the slab will be removed in two years, they will be able to examine in detail how it performed.
I hope the Sizewell C project team are following High Speed Two’s lead.
Rail Support For Sizewell C
The Sizewell site has a rail connection and it appears that this will be used to bring in construction materials for the project.
In the January 2023 Edition of Modern Railways, there is an article, which is entitled Rail Set To Support Sizewell C Construction.
It details how sidings will be built to support the construction, with up to four trains per day (tpd), but electrification is not mentioned.
This is surprising to me, as increasingly, big construction projects are being managed to emit as small an amount of carbon as possible. Sizewell C may be an isolated site, but in Sizewell B, it’s got one of the UK’s biggest independent carbon-free electricity generators a couple of hundred metres away.
The writer of the Modern Railways article, thinks an opportunity is being missed.
I feel the following should be done.
- Improve and electrify the East Suffolk Line between Ipswich and Saxmundham Junction.
- Electrify the Aldeburgh Branch Line and the sidings to support the construction or agree to use battery-electric or hydrogen zero-carbon locomotives.
Sizewell C could be a superb demonstration project for low-carbon construction!
Sizewell C Deliveries
Sizewell C will be a massive project and and will require a large number of deliveries, many of which will be heavy.
The roads in the area are congested, so I suspect rail is the preferred method for deliveries.
We already know from the Modern Railways article, that four tpd will shuttle material to a number of sidings close to the site. This is a good start.
Since Sizewell A opened, trains have regularly served the Sizewell site to bring in and take out nuclear material. These occasional trains go via Ipswich and in the last couple of years have generally been hauled by Class 88 electro-diesel locomotives.
It would be reasonable to assume that the Sizewell C sidings will be served in the same manner.
But the route between Westerfield Junction and Ipswich station is becoming increasingly busy with the following services.
- Greater Anglia’s London and Norwich services
- Greater Anglia’s Ipswich and Cambridge services
- Greater Anglia’s Ipswich and Felixstowe services
- Greater Anglia’s Ipswich and Lowestoft services
- Greater Anglia’s Ipswich and Peterborough services
- Freight services serving the Port of Felixstowe, which are expected to increase significantly in forthcoming years.
But the Modern Railways article says this about Saxmundham junction.
Saxmundham junction, where the branch meets the main line, will be relaid on a slightly revised alignment, retaining the existing layout but with full signalling giving three routes from the junction protecting signal on the Down East Suffolk line and two in the Down direction on the bidirectional Up East Suffolk line. Trap points will be installed on the branch to protect the main line, with the exit signal having routes to both running lines.
Does the comprehensive signalling mean that a freight train can enter or leave the Sizewell sidings to or from either the busy Ipswich or the quieter Lowestoft direction in a very safe manner?
I’m no expert on signalling, but I think it does.
- A train coming from the Lowestoft direction needing to enter the sidings would go past Saxmundham junction on the Up line. Once clear of the junction, it would stop and reverse into the branch.
- A train coming from the Ipswich direction needing to enter the sidings would approach in the wrong direction on the Up line and go straight into the branch.
- A train leaving the sidings in the Lowestoft direction would exit from the branch and take the Up line until it became single track. The train would then stop and reverse on to the Down line and take this all the way to Lowestoft.
- A train leaving the sidings in the Ipswich direction would exit from the branch and take the Up line all the way to Ipswich.
There would need to be ability to move the locomotive from one end to the other inside the Sizewell site or perhaps these trains could be run with a locomotive on both ends.
The advantage of being able to run freight trains between Sizewell and Lowestoft becomes obvious, when you look at this Google Map, which shows the Port of Lowestoft.
Note.
- The Inner Harbour of the Port of Lowestoft.
- The East Suffolk Line running East-West to the North of the Inner Harbour.
- Lowestoft station at the East side of the map.
I doubt it would be the most difficult or expensive of projects to build a small freight terminal on the North side of the Inner Harbour.
I suspect that the easiest way to bring the material needed to build the power station to Sizewell would be to do the following.
- Deliver it to the Port of Lowestoft by ship.
- Tranship to a suitable shuttle train for the journey to the Sizewell sidings.
- I estimate that the distance is only about 25 miles and a battery or hydrogen locomotive will surely be available in the UK in the next few years, that will be able to provide the motive power for the return journey.
In The TruckTrain, I wrote about a revolutionary freight concept, that could be ideal for the Sizewell freight shuttle.
In addition, there is no reason, why shuttle trains couldn’t come in from anywhere connected to the East Suffolk Line.
Zero-Carbon Construction
Sizewell C could be the first major construction site in the UK to use electricity rather than diesel simply because of its neighbour.
Conclusion
I shall be following the construction methods at Sizewell C, as I’m fairly sure they will break new ground in the decarbonisation of the Construction industry.
Hyperbat In Multimillion-Pound Deal To Supply Battery Packs For Lotus Supercar
The title of this post, is the same as that of this article on The Times.
Lotus or supercars for that matter, will not be a big market for battery packs, but they will be a high-profile one. The article in The Times may well flush out a few good sales leads from companies who want to decarbonise their products.
Many years ago, I did a consultancy job for Cummins, where my software was used to look for faults in their engine testing system. One of their engineers explained to me that they had a sales and production philosophy that could handle all markets from the large down to small niche ones. He said that we can’t tell which niche markets are going to be successful.
In the last couple of years Cummins have embraced hydrogen very strongly and it looks like they are adopting a similar philosophy.
So in the Cummins engine business model, it looks like the niche market is important.
I suspect that what goes for the diesel engine market will also go for the electric transmission market, with niche markets being nicely profitable and an important part of sales.
It looks to me that Hyperbat are going for that market, backed up by the engineering and battery experience of Williams Advanced Engineering and the manufacturing knowledge and logistics of Unipart.
Note that Williams Advanced Engineering is now owned by Australian billionaire; Andrew Forrest, through his company; Fortescue Future Industries. I wrote about this purchase in Fortescue Buys Williams Engineering In Major Push Into High Performance Batteries.
On the Hyperbat web site, this is said about their manufacturing facility.
The facility is about to double in size to meet current needs, with plans to double again in the next 2 years.
The factory is based on the site of a former exhaust plant and reintroduces manufacturing to the area, with an environmentally sustainable future.
Capacity of the factory is approximately 10,000 packs per year.
I;m sure the company, has enough backing for a very successful future.
Wabtec Planning For Transition From Diesel
The title of this post, is the same as that of this article on trains.com.
It has this sub-title.
At InnoTrans, company looks at role of batteries, hydrogen in railroading’s future.
It is very much a must-read, that gives a road-map of their plans to decarbonise rail freight, by the use of both battery and hydrogen power.
Wabtec Signs $600M MoU With Kazakhstan Railway Company
The title of this post, is the same as that of this article on Seeking Alpha.
This is the introductory paragraph.
Wabtec announced Tuesday signing of a $600M memorandum of understanding with Kazakhstan Temir Zholy for 150 FLXdriveTM battery-electric shunters and modernization work to transform the mainline fleet into NextFuelTM liquid natural gas-powered (LNG) locomotives.
Note.
- It is for 150 shunting locomotives, which is not a small number.
- A lot of the work will be done in Kazakhstan.
- Wabtec certainly seem to be getting their FLXdrive technology about.
- Obviously LNG locomotives must be a good route to reduce carbon emissions for diesel locomotives.
- The Kazahks seem pleased with the deal for economic and decarbonisation reasons.
But what surprises me about this deal, is that it has not gone to Russia. Does this say something about Putin’s lack of friends.
A Battery-Electric Class 99 Locomotive
In GB Railfreight Plans Order For Future-Proofed Bi-Mode Locomotives, I introduced the Class 99 locomotive, for which the first order was announced by Stadler and GB Railfreight today.
This was the start of that post, which I wrote in early March 2022.
The title of this post, is the same as that of this article on Railway Gazette.
This is the introductory paragraph.
GB Railfreight is planning to order a fleet of main line electro-diesel locomotives with a modular design which would facilitate future replacement of the diesel engine with a battery or hydrogen fuel cell module.
The rest of the article gives clues to the deal and the specification of the locomotives.
- Negotiations appear to have started with Stadler for locomotives to be built at their Valencia plant.
- Twenty locomotives could be ordered initially, with options for thirty.
- The locomotive will be Co-Co bi-modes.
- The diesel engine will be for heavy main line freight and not just last-mile operations.
- They would be capable of hauling freight trains between Ipswich and Felixstowe, within two minutes of the times of a Class 66 locomotive.
- They will be of a modular design, so that in the future, the diesel engine might be replaced by a battery or fuel cells as required and possible.
They have provisionally been called Class 99 locomotives.
Note the introductory paragraph of the Railway Gazette article.
GB Railfreight is planning to order a fleet of main line electro-diesel locomotives with a modular design which would facilitate future replacement of the diesel engine with a battery or hydrogen fuel cell module.
What sort of range and performance will this give to a Class 99 locomotive?
In Class 99 Electro-Diesel Locomotive Order Confirmed, I came to this conclusion.
It does appear that a design based around the latest version of a Caterpillar C175-16 diesel engine will be possible.
The easiest way to create a battery-electric Class 99 locomotive would be to replace the Caterpillar C175-16 diesel engine with the largest and most efficient batteries possible, add regenerative braking to battery and the best control system for the locomotive and the batteries, that engineers can devise.
These are my thoughts.
Range Of A Euro Dual On Diesel
Consider.
- A Euro Dual locomotive has a 3,500 litre fuel tank.
- A Euro Dual locomotive has a fuel consumption of 1039.3 L/hr.
This should allow the locomotive to run for about three hours and twenty minutes or about 250 miles.
Obviously, any electrification on the route, will increase the range.
Weight Of The Diesel Engine
This data sheet for the Caterpillar C175-16 diesel engine gives a weight of over twenty tonnes, which is certainly a lot of weight.
You’ve also got the weight of the fuel tank, which could also contain in the Euro Dual hold nearly three tonnes of diesel.
I will assume that the weight of a Caterpillar C175-16 diesel engine and the associated gubbins could be as high as 25 tonnes.
How Much Energy Could A Twenty Tonne Battery Hold?
In Innolith Claims It’s On Path To 1,000 Wh/kg Battery Energy Density, which was written two years ago.
This was my conclusion of that post.
I am led to believe these statements are true.
- Tesla already has an energy density of 250 Wh/Kg.
- Tesla will increase this figure.
- By 2025, the energy density of lithium-ion batteries will be much closer to 1 KWh/Kg.
- Innolith might achieve this figure. But they are only one of several companies aiming to meet this magic figure.
These figures will revolutionise the use of lithium-ion batteries.
I feel it is reasonable to go along with Tesla’s figure of 250 Wh/Kg, which gives a 5 MWh battery could replace the C175-16 diesel engine, if it had a total weight of 20 tonnes.
If the battery could have a total weight of 25 tonnes, the battery would have a capacity of 6.25 MWh.
It does look like the Caterpillar C175-16 diesel engine and the associated gubbins could be replaced by a substantial battery.
As the years go by, the capacity of the batteries will only grow.
Will Battery-Electric Class 99 Locomotives Have Regenerative Braking?
According to Wikipedia, Stadler Euro Dual locomotives do have regenerative braking, so it would seem likely, that this could be used to recharge the batteries, in addition to 25 KVAC overhead electrification, where it is available.
I will assume that battery-electric Class 99 locomotives will have regenerative braking.
How Long Could A Battery-Electric Class 99 Locomotive Run On Batteries?
Consider.
- To have the performance of a Class 99 locomotive on diesel, the locomotive would need to output 2,800 kW.
Without regenerative braking this would give these figures.
- A 5 MWh battery would run for at least one hours and 47 minutes.
- A 6.25 MWh battery would run for at least two hours and 13 minutes.
Add in regenerative braking and short strategic lengths of electrification and large parts of the UK network would be opened up to electrified trains.
Conclusion
Stadler have probably done extensive simulations of the UK network with battery-electric Class 99 locomotives, so they would know the true potential of these locomotives.
Fortescue Unveils World-First Electric Train Using Gravity To Recharge
The title of this post, is the same as that of this article on InnovateAus.
These two paragraphs summarise the project.
Fortescue has announced the development of an electric train that recharges itself using gravity, as the Australian resources giant finalises its acquisition of UK-based Williams Advanced Engineering.
Fortescue is dedicating $50 million, in partnership with Williams Advanced Engineering (WAE), for research and development on the Infinity Train, which fully recharges its battery using gravitational energy when it descends.
Note.
- Most of Australia’s iron ore is mined in the Pilbara region of Western Australia.
- There are at least four railways in Pilbara leading to the coast.
- As the mines are higher than the coast, the heavily loaded trains will be going downhill, whereas the empties will be going uphill.
- There would certainly appear to be scope for charging going to the coast and coming back on a full battery with the empties.
- 94 % of Australia’s iron ore exports are transported by train from Pilbara to the coast.
There are hundreds of locomotives used for transportation of Iron ore from Pilbara to the coast.
Will Williams Convert Existing Locomotives?
I suspect they will as this is route that Wabtec is taking with their FLXdrive locomotives.
Will Williams Convert Locomotives For Other Pilbara Companies?
I suspect what Andrew Twiggy Forest wants he gets.
Could Williams Convert Other Diesel Electric Locomotives
I suspect they could and I wouldn’t rule out seeing a battery-electric Class 66 locomotive.
I laid out my thoughts in Could Class 66 Locomotives Be Converted Into Battery-Electric Locomotives?.
Union Pacific Railroad Makes Largest Investment In Wabtec’s FLXdrive Battery-Electric Locomotive
The title of this post, is the same as that of this press release from Union Pacific.
This is the first three paragraphs.
Union Pacific Railroad (NYSE: UNP) today announced the purchase of 10 FLXdrive battery-electric locomotives from Wabtec Corporation (NYSE: WAB). The order, which marks the largest investment in battery technology by a North American railroad, will upgrade Union Pacific’s rail yard infrastructure and support its commitment to significantly reduce greenhouse gas emissions.
“As an industry leader, Union Pacific is pioneering a major application of battery power in its rail yards,” said Rafael Santana, President and CEO for Wabtec. “Battery power is an ideal solution to reduce the environmental impact and costs of yard operations. Using the FLXdrive in the rail yard can significantly improve local air quality, as well as reduce noise by up to 70% for neighboring communities.”
The approximately 2.5-MWh locomotives are each powered solely by 7,000 battery cells, providing Union Pacific a zero-emission solution for its yard operations. The 10 FLXdrives will enable the railroad to eliminate 4,000 tons of carbon annually from its rail yards, the equivalent of removing 800 cars from the highway. The new locomotives will be manufactured in the United States with the first units being delivered to Union Pacific in late 2023.
It would appear that the major use will be in their rail yards.
There is also this second press release from Union Pacific, which is entitled Union Pacific Railroad To Assemble World’s Largest Carrier-Owned Battery-Electric Locomotive Fleet.
This is the first paragraph.
Union Pacific Railroad (NYSE: UNP) today announced plans to purchase 20 battery-electric locomotives for testing in yard operations. The combined purchases and upgrades to yard infrastructure are expected to exceed $100 million, representing the largest investment in battery-electric technology by a U.S. Class I railroad. The locomotives will be acquired from Progress Rail, a Caterpillar company, and Wabtec Corporation (NYSE:WAB), two companies at the forefront of locomotive innovation, and will be the world’s largest carrier-owned battery-electric locomotive fleet in freight service.
The press release also says that Union Pacific will be netzero by 2050.
Conclusion
All of this action in the United States and Australia with battery-electric locomotives, from two manufacturers; Progress Rail and Wabtec, leads me to the conclusion, that proposals to create battery-electric locomotives from Class 66 or Class 68 locomotives in the UK, will soon be being discussed by the owners of the locomotives and Wabtec and Stadler.
Suppliers Sought For New Bi-Mode Locomotives For TransPennine Express And Great Western Railway
The title of this post, is the same as that of this article on Rail Advent.
These three paragraphs give a summary of the proposed fleet of locomotives required by First Group for their two operations.
TransPennine Express is looking for expressions of interest from suppliers for a fleet of at least 15 bi-mode locomotives for use on with its Mk5 carriages.
The provision released by First Group is for up to 30 bi-mode locomotives, with an additional 5 for use on Great Western Railway’s Sleeper Service.
The operators say that the new locomotives must have the capability to be powered by overhead wires as well as being able to operate with an alternate traction mode, IE Diesel or Battery, where routes are not yet electrified or for use as a contingency.
I have also read the detailed proposal, which can be downloaded from this page of the First Group web site.
- The locomotives must be capable of hauling a train at 100 mph.
- First Group are putting a high emphasis on environmental impact of the locomotives.
- The locomotives must be compatible with the latest emission regulations.
- The locomotives must be low-noise.
- The locomotives must be capable of hauling seven coaches, including a driving van trailer.
Nothing in the request for proposals would appear to be too challenging.
I have some thoughts.
The Number Of Locomotives For TransPennine Express
Currently, TransPennine Express has a fleet of fourteen Class 68 locomotives and enough coaches and driving van trailers to create thirteen rakes of Mark 5A coaches.
So why do TransPennine Express talk of up to thirty locomotives?
- Fifteen locomotives would handle the current services, so thirty could cover new services or more services on the current locomotive-hauled routes.
- Manchester Airport and Cleethorpes and Manchester Piccadilly and Hull are run by Class 185 diesel trains, which will need replacing at some future time.
- First Group probably know the costs of running Class 802 trains and locomotives with rakes of coaches better than anyone , so are they thinking about swapping some Class 802 trains for locomotives with rakes of coaches?
The last point would be one for the accountants.
But I am led to the conclusion, that TransPennine Express could be expanding and also decarbonising the long routes still operated by Class 185 trains.
The Number Of Locomotives For Great Western Railway
Currently, Great Western Railway has a fleet of four Class 57 locomotives to haul the Night Riviera.
Five replacement locomotives would probably be enough.
Could A Battery-Electric Locomotive Handle The TransPennine Express Requirement?
Currently, there are gaps in the electrification of the TransPennine network.
- Manchester Victoria and Stalybridge – 7.7 miles – Electrification in progress
- Stalybridge and Huddersfield – 18 miles
- Huddersfield and Dewsbury – 8 miles – Electrification in progress
- Dewsbury and Leeds – 9.1 miles
- Leeds and York – 25.6 – Electrification in progress
- Northallerton and Redcar – 28.8 miles
- Manchester Piccadilly and Stalybridge – 7.5 miles
- Leeds and Hull – 51.8 miles
- Doncaster and Cleethorpes – 72.1 miles
- Scarborough and York – 42 miles
- Doncaster and Sheffield – 18.7 miles
- Sheffield and Stockport – 36.8 miles – Rumoured to be electrified
Note.
- Many gaps are quite small.
- The longest gaps are on easy routes.
- Sheffield will be electrified for the Midland Main Line.
- A length of electrification at Scunthorpe could ease Doncaster and Cleethorpes.
I feel that a battery-electric locomotive with a range of a hundred miles hauling seven coaches, would be able to handle all the TransPennine routes.
If the train could run the routes with an electricity consumption of 4 kWh per vehicle-mile, seven coaches would need 4 * 8 * 100 = 3.2 MWh of battery storage.
Note.
- A 3.2 MWh battery would weigh around 3.2 tonnes, which would be less than the diesel engine in a Class 68 locomotive.
- Regenerative braking to batteries could be used to improve range.
- In How Much Power Is Needed To Run A Train At 125 Or 100 mph?, I calculated that an InterCity 125 needs 1.81 kWh per vehicle mile to maintain 100 mph.
I am fairly certain, that a well-designed efficient battery-electric locomotive would be able to handle all of the routes for TransPennine Express.
Could A Battery-Electric Locomotive Handle The Night Riviera?
I have just looked up the Southbound Night Riviera on Real Time Trains.
- It leaves Paddington at 23:50.
- It is typically eight coaches and a Class 57 locomotive.
- The train is planned to run at 75 mph.
- The first 53 miles between Paddington and Newbury are electrified.
- There is a stop of one hour and 39 minutes at Exeter.
- Newbury and Exeter is 120.4 miles
- Exeter and Penzance is 130.8 miles
The Northbound Night Riviera only has a five minute stop at Exeter and two minutes stops at Totnes, Newton Abbott and Taunton.
A battery-electric locomotive would need a range of 140 miles hauling eight coaches.
- Some stops like Plymouth may need to be lengthened by a few minutes to charge the batteries.
- Extra stops of perhaps five minutes could be added to top-up the batteries.
- The train would be limited to 75 mph, which would improve efficiency.
- It might even be prudent to electrify the uphill track of some of the steeper parts of the route.
But think of the marketing advantages of a zero-carbon sleeper train!
Conclusion
When I saw First Group’s proposals, I thought that they were over ambitious.
But after doing a few simple calculations, I think they can decarbonise some, but not all of the TransPennine Express services and the Night Riviera.
Penmaenmawr Quarry Rail Terminal Opens
The title of this post, is the same as that of this article on Railway Gazette.
These are the first two paragraphs.
Hanson has reopened its Penmaenmawr railhead in north Wales, as part of its strategy to reduce vehicle movements and associated CO2 emissions.
The quarrying company has spent £300 000 refurbishing the facility, including upgrades to the railhead conveyor which was last used in 2012. The first trial service was operated by GB Railfreight and transported stone to the Tuebrook depot near Liverpool to test the equipment and uncover any operational issues within the quarry and at the railhead.
The aim is to one one train per week between North Wales and North West England.
This Google Map shows the Penmaenmawr railhead.
Note.
- Penmaenmawr station is in the top right corner of the map.
- The railhead is in the bottom-left corner of the map.
- The North Wales Expressway is between the railway and the beach.
There is a conveyor leading to the South and this second Google Map shows the vast quarry complex.
Penmaenmawr station is in the top right corner of the map.
It does appear to me, that this is a good move by Hanson.
- If the quarry can be worked economically, it is surely worthwhile exploiting.
- Opening new quarries, is generally not an easy process.
- Even using diesel locomotives on the aggregate trains, probably saves carbon compared to trucks.
- Closing the quarry would probably not be good for the area.
- They only want to run one train per week.
- I wonder, if the train goes through the Halton Curve that opened a couple of years ago.
- Penmaenmawr and Tuebrook Sidings are a route of about eighty miles.
But I think in the future it could be a very good move, as at least one of three things will happen.
- The North Wales Coast Line will be electrified.
- Someone will develop a hydrogen-electric freight locomotive.
- Wabtec will develop their battery-electric locomotive for the UK with a UK-sized FLXdrive battery.
All possibilities will help Hanson lower the carbon footprint of the route.
Given too, that Hanson will probably decarbonise their quarrying operations by using hydrogen-powered equipment, it should be possible to arrange a hydrogen supply at Penmaenmawr.
BHP Joins The Party On Electric Rail
The title of this post, is the same as that of this article on Australian Mining.
This is the introductory paragraph.
BHP will add four battery-electric locomotives to its Western Australian rail network, becoming the fourth major miner to improve rail decarbonisation efforts in Australia since mid-December.
These are some details of the locomotives.
- Two are from Progress Rail and two are from Wabtec.
- The locomotives have 14.5 MWh batteries.
- The locomotives will be delivered by 2023.
BHP will also investigate the use of regenerative braking using the topography of the rail route.
With four companies going electric, it does seem that Australian mining, is very much driving the move to battery-electric heavy-haul freight.
Considering, that Wabtec only formally launched the FLXdrive concept in Pittsburgh in September last year, which I wrote about in FLXdrive ‘Electrifies’ Pittsburgh, that would appear to have been good going.
The Anonymous Widower
