Designing A Battery-Powered Mountain Goat
When I wrote Up To Ebbw Vale From Newport, this comment was posted.
I’m not surprised that the Class 150 train, had no difficulty in climbing up to Ebbw Vale Town. The max gradient is around 1 in 65. There are plenty of places in Britain where gradients are steeper and indeed part of the type test for all dmus was to climb the 2 mile, 1 in 37.7 Lickey Incline starting a couple of hundred metres before the beginning of the slope.
It certainly got me thinking.
Could a line like Newport and Ebbw Vale be decarbonised, by simply fitting batteries to an appropriately-sized electric train?
- The battery would be charged using the 25 KVAC overhead electrification in Newport station.
- The train would climb the hill to Ebbw Vale Town on battery power.
- Coming down the regenerative braking would charge the battery.
- Once in the platform at Newport station, the battery would be topped up, to the level needed to climb the hill, from the existing electrification.
The question is can the train carry enough juice in a battery?
I will work the example through with a three-car Class 331 train.
- I have chosen a Class 331 train, as CAF have a factory in Newport.
- The train weighs 30.48 tonnes.
- It has 213 seats.
- If I assume that each passenger is 80 Kg including baggage, bikes and buggies, that gives a mass of 17.04 tonnes or a total mass of 47.08 tonnes.
- The difference in altitude between Ebbw Vale Town and Newport is 764 feet.
Using Omni’s Potential Energy Calculator, that gives a value of 29.9 kWh.
This OpenRailwayMap shows the tracks from Newport to Pye Corner.
Note.
- Red tracks are electrified and black ones are not.
- Newport station is in the North-East corner of the map, with the South Wales Main Line running through.
- Pye Corner station is marked by the blue arrow and is the first station on the climb to Ebbw Vale.
- The unelectrified Ebbw Vale branch has a triangular junction with the electrified South Wales Main Line.
- The electrification continues for a short way towards Pye Corner and goes all the way to Newport and Cardiff.
- Trains take 24 minutes to turn round in Newport.
- Newport and Ebbw Vale Town is about twenty miles.
It can be safely said that trains will start their climb to Ebbw Vale with a full battery.
What Battery Size Will Be Needed?
I don’t think it will be that large and it will be the smallest battery, that could take a train up the hill.
As part of the climb is double track, the up track could be electrified to enable a smaller battery to be used, which would mean less power would be needed, due to the lower weight.
Conclusion
I believe that it will be possible to fit CAF’s Class 331 trains with a battery large enough to take a train up the hill to Ebbw Vale Town.
Ebbw Vale Town Station – 3rd February 2024
I took these pictures as Ebbw Vale Town station.
Note.
- There is a cableway to the main town.
- But t wasn’t working as it was Saturday.
- There is a large college.
- There was no information, as to how to get to the town.
- The Cardiff and Newport trains alternate every half hour.
The area certainly needed better information and perhaps a cafe, so that commuters can buy a coffee for their journey!
These are my thoughts.
The Capacity Of Ebbw Vale Town Station
According to this page on the Network Rail web site, the single platform at Ebbw Vale Town station is approximately 150 metres in length to fit up to six train carriages.
As at the current time, services are run by two- or three-car, it would appear that if a train failed in the station, the platform is long enough to accommodate another train to continue the services.
In the Wikipedia entry for Ebbw Vale Town station, it is indicated that a second platform could be built. There is certainly enough space.
Operation Of Ebbw Vale Town Station
I was at Ebbw Vale Town station for nearly two hours and I watched three Newport and two Cardiff trains arrive and leave every half-hour.
- I had arrived on the first train from Newport.
- The Cardiff trains were busy with passengers for the rugby.
- I took the third Newport train, so I could catch my train back to Reading.
- The system seemed to be working well.
Is there another single-platform station on a branch line, that serves two main line stations alternatively every half hour?
Increasing Capacity To Ebbw Vale Town Station
In Designing A Battery-Powered Mountain Goat, I stated that I believe that a small fleet of CAF’S Class 331 trains fitted with batteries could handle the Cardiff and Newport services to Ebbw Vale Town.
The sight and the curiosity of battery-electric trains climbing up the hills will certainly create more traffic on the route.
The simple solution is to lengthen the trains and that is easy at the moment, as the services are run using Class 150 trains with a Class 153 to add extra capacity, where needed.
But could a half-hourly service be run to both Cardiff and Newport?
This would double the capacity and make it more user friendly.
Nothing is said on the Internet about whether this is possible on not, but I believe that with modern digital signalling and battery-electric trains, with better performance than the elderly British Rail-era diesels, that it would be possible to run a half-hourly service to both Cardiff and Newport.
Conclusion
I believe that Network Rail have done a good job in designing this scheme.
City Of London: Skyscraper As Tall As The Shard Planned
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A skyscraper the same height as The Shard is being planned for London.
These are the first three paragraphs.
One Undershaft would reach 74-storeys, according to revised plans submitted to City of London Corporation.
The amended proposals include a new stepped design instead of a previous rectangular shape, with the building initially receiving approval in 2016.
A public consultation has taken place on the proposals, which would see London’s highest public viewing gallery at the top of the skyscraper.
This Google Map shows the site.
Note.
- One Undershaft is indicated by the red arrow.
- The Gherkin is next door.
- This web page shows the architect’s visualisation.
I don’t think it will a sore thumb like The Shard, which intrudes into so many London views.
West London Orbital: Line Could Be Reused For Passengers
The title of this post is the same as that of this article on the BBC.
This is the sub-heading.
A railway line that stopped serving passengers in 1902 could be brought back into use as a route called the West London Orbital.
These are the first three paragraphs.
The Dudding Hill loop runs from Acton to Cricklewood and currently only takes freight trains.
Transport for London (TfL) published a strategic document in 2021 saying it would be “a catalyst for relieving road congestion in west London”.
It is estimated by TfL more than 11 million people a year would use it.
This is also said.
Sharma Tatler, the deputy leader of Brent Council, called the plan “a no-brainer”.
I agree with that.
These are my thoughts.
Finding The Money
Money will be needed for the following.
- To build and update the stations on the route.
- To acquire the new trains needed.
- To bring the track and signalling up to the required standard.
Note.
- It appears that around a dozen freight trains use the route on a typical day.
- Hopefully, Network Rail can come up with an affordable plan for the track and signalling, as the route is used by freight trains at the present time.
- I would envisage that the trains used would be a version of the current Class 710 trains used on the Overground. These could probably be leased.
I wouldn’t be surprised that the cost of the stations, will be the major part of the building of the line.
Building the stations is probably, the easiest place to bring in private finance. Especially, if stations incorporated housing or other developments.
On a train going to the North a few years ago, I met two infrastructure funders from L & G (in Standard Class), who were going to lend a company 50 billion to develop a large residential housing site. We got talking and I asked them if they would develop a mythical branch line with a good station site at the end. (Think Felixstowe!) I asked if they’d fund housing and possibly the trains. They said yes!
So I suspect that the West London Orbital could also be funded in the same way, as there are a few stations to build and upgrade. Much needed housing could be built on top or nearby.
I would also deck-over Neasden Depot and build housing in town blocks on top.
I believe that the West London Orbital could be funded.
Electrification
The Wikipedia entry for the West London Orbital describes the route like this.
The route would run for approximately 11 miles (17 km) from West Hampstead and Hendon at the northern end to Hounslow at the western end via Brent Cross West, Neasden, Harlesden, Old Oak Common, South Acton and Brentford.
Note.
- There is 25 KVAC overhead electrification at the Northern end of the route between West Hampstead Thameslink and Hendon stations.
- The Dudding Hill Line between the Midland Main Line and Acton Wells Junction is not electrified.
- The North London Line between Acton Wells Junction and Acton Central station is electrified with 25 KVAC overhead wires.
South of Acton Central station, the electrification gets complicated as this OpenRailwayMap shows.
Note.
- Acton Central station is in the North-East corner of the map.
- Brentford station is in the South-West corner of the map.
- The red track is electrified with 25 KVAC overhead and it is used North of Acton Central station.
- Mauve track is electrified with British Rail third rail.
- Ptnk track is electrified with London Underground third rail.
- Black track is not electrified.
- West London Orbital trains between West Hampstead Thameslink and Hounslow will use the direct route between Acton Central and Brentford.
- West London Orbital trains between Hendon and Kew Bridge terminate at the South-Eastern point of the triangular junction.
It seems that trains will be needed that can use both types of electrification and none.
New Trains
Because of the requirement of the trains to be able to use both types of electrification and be self-powered, the trains will either have hydrogen or battery power to augment electric traction.
Hendon and Hounslow is 11.3 miles and this will be longer than any service distances, so I suspect that a battery-electric train could handle the route.
In this article in Global Rail News from 2011, which is entitled Bombardier’s AVENTRA – A new era in train performance, gives some details of the Aventra’s electrical systems. This is said.
AVENTRA can run on both 25kV AC and 750V DC power – the high-efficiency transformers being another area where a heavier component was chosen because, in the long term, it’s cheaper to run. Pairs of cars will run off a common power bus with a converter on one car powering both. The other car can be fitted with power storage devices such as super-capacitors or Lithium-ion batteries if required. The intention is that every car will be powered although trailer cars will be available.
Unlike today’s commuter trains, AVENTRA will also shut down fully at night. It will be ‘woken up’ by remote control before the driver arrives for the first shift
This was published over ten years ago, so I suspect Bombardier (or now Alstom) have refined the concept.
Bombardier have not announced that any of their trains have energy storage, but I have my suspicions, that both the Class 345 and Class 710 Aventra trains use super-capacitors or lithium-ion batteries, as part of their traction system design.
- I was told by a Bombardier driver-trainer that the Class 345 trains have an emergency power supply. When I said “Batteries?”, He gave a knowing smile.
- From the feel of riding on Class 710 trains, as a Control Engineer, I suspect there is a battery or supercapacitor in the drive system to give a smoother ride.
I also feel that the Aventra has been designed, so that it can accept power from a large variety of sources, which charge the battery, that ultimately drives the train.
Up To Ebbw Vale From Newport
I took these pictures as my train climbed the hill up to Ebbw Vale Town station.
Note.
- The Class 150 train, that I was in had no difficulty in climbing up to Ebbw Vale Town.
- The dtations and track appeared in good condition.
- The weather was getting wetter, which didn’t help the pictures.
It’s a typical South Wales valley packed with houses and factories and with a small river and a few chapels an rugby pitches through in.
My Train To Wales Today Divided At Swansea
According to the Wikipedia entry for Great Western Railway, seven of their hourly services to Swansea now continue to Carmarthen station.
- My train was such a train, although I got off at Newport station.
- The service was formed of two five-car Class 800 trains; 800026 and 800027.
- I would assume that at Swansea, the trains will have split and the rear train will reverse and continue to Carmarthen.
- The lead train would stay in Swansea.
- I have traced the Carmarthen train on Real Time Trains and it clearly shows that the train picked up another train at Swansea as it came back to London.
All the trains involved in the splitting and joining were Class 800 trains.
The splitting and joining at Swansea means the following.
- There is a ten-car train between London and Swansea, which will give maximum capacity to and from the rugby at Cardiff.
- There is a five-car train between Swansea and Carmarthen, which doesn’t need the capacity of a ten-car train.
This is probably a more efficient use of trains and it maximises capacity to and from Cardiff, in both directions.
Is this splitting and joining at Swansea, the first regular use of the technique in service with Class 800 trains?
This YouTube video shows the station displays at Reding, when a Swansea/Carmarthen pair go through.
The Most Crowded Train I’ve Been On For Sixty-Plus Years
I started going to Tottenham Hotspur matches by myself somewhere between the age of fourteen and sixteen.
- I used to take the 107 bus from where we lived in Oakwood to Enfield Town station and then get the electric trains to White Hart Lane.
- I don’t remember much about the trains, but they were slam door stock.
- I remember this as we used to fold the doors back before the train entered the station and jump out when the train got to running speed.
- Coming back into Enfield Town station, this was essential, otherwise you wouldn’t be to the front of the queue for the 107 bus.
- Those trains returning from White Hart Lane were incredibly packed.
And I haven’t been on a train as crowded until today.
Today, I planned a simple mission to go to Ebbw Vale Town station and back to see the working of the new service between Newport and Ebbw Vale Town station.
- As I often do, I used my Freedom Pass on the Elizabeth Line to get to Reading.
- At Reading station, I bought a Super Off-Peak Return from Reading to Ebbw Vale Town for £47.05 with my Senior Railcard.
- By comparison, a Super Off-Peak Return from Paddington to Ebbw Vale Town is £57.55 with a Railcard.
The first train today, on which I could use my cheap ticket was the 11:13 from Reading.
- I had hoped, that there would still be a few seats left at Reading, as there are always a few, who use Great Western Railway’s fast trains between Paddington and Reading.
- I also expected, that many going to the Wales and Scotland match in Cardiff would take later trains.
- Unfortunately, quite a few Scots and Welsh supporters got on at Reading.
- It was a wrong decision, as there wasn’t a spare seat anywhere.
So in the end, I stood all the way from Reading to Newport.
I would hope that next time, that Scotland play Wales in Cardiff, that Great Western Railway add some more capacity.
Improvements To Oakwood Station
This post on IanVisits is entitled Enfield Council Outlines Possible Rail Station Upgrades.
By reading Enfield Council documents, Ian has found possible station improvements that might happen.
Ian says this about Oakwood station.
Building around 50 homes on the station car park should contribute to street improvements around the station.
This Google Map shows the station and its two car parks.
Note.
- The Piccadilly Line runs North-West-South-East diagonally across the map.
- Cockfosters station is to the North-West.
- Southgate station is to the South-East.
- Oakwood station is in the middle of the map and marked by a London Underground roundel.
- The car park to be developed is to the North-East of the station.
I took these pictures.
Note.
- The car-park was full.
- The station is step-free.
- Barnard Cook was there, when I lived in Oakwood in the early 1960s.
I can’t see any problems building a few houses on the car-park, but what will happen to the cars?
To me though Oakwood station is defined by this post; The Place Where The Bottom Fell Out Of A Drawer.
Residents Invited For A Bird’s Eye View Of How Mid Cornwall Metro Will Transform Transport Links In Cornwall
The title of this post, is the same as that of this article on RailUK.
This is the first paragraph.
Residents have been encouraged to attend an event at the Hotel Victoria in Newquay on Friday 9 February (10am – 7pm) and Saturday 10 February (10am – 4pm) when they’ll be able to see for themselves how the Mid Cornwall Metro, funded by Cornwall Council and £50 million of government Levelling Up Funding, will create a sustainable transport corridor through central Cornwall.
This is the last paragraph.
Another engagement event will take place at the Stannary on the University campus at Tremough on Friday 1 March from 10am to 5pm, and the Temperance Hall, Lower Market Street, Penryn TR10 8BH on Saturday 2 March from 10am to 4pm.
If the weather looks good, then I might go.
This page, with an excellent graphic, explains the Mid Cornwall Metro.
New £24m Platform To Boost City Train Services
The title of this post is the same as that of this article on the BBC.
These are the first three paragraphs.
Bradford’s Forster Square station is to get a new £24m platform to boost rail services in the city.
Rail Minister Huw Merriman said the government-funded scheme would futureproof the station for generations to come.
It could lead to five more trains to London each day, the Department for Transport said.
There are positive comments from Bradford Council leader Susan Hinchcliffe and LNER.
These are my thoughts.
Where Will The New Platform Be Built?
This OpenRailway Map sows the layout of the current three platforms at Bradford Forster Square station.
The Wikipedia entry for Bradford Forster Square station, says this about platform usage.
During off-peak hours most trains use platforms 1 (for Skipton) and 2 (Leeds and Ilkley) – platform 3 is mainly used during weekday peak periods and in the evening, though a spare set is usually stabled here between 09.00 and 16.00 each weekday.
This picture was taken on the only time I visited the station in 2017.
Note.
- The middle platform is numbered 2b.
- As Bradford Forster Square station is a terminal station, I must have taken this picture from the Southern end of the station.
- From Network Rail’s plan of the station, it looks like Platform 1 is on the right or East and Platform 3 is on the left or West.
This page on the EnglandRover web site confirms that Platform 3 is the Western platform.
This article on the Bradford Argus is entitled Work On New Platform To Begin In Spring After £24m Boost.
This is a paragraph.
The extra platform will be built at the side of the station closest to Forster Square Retail Park. It means the station will expand outwards by a few metres, and the platform construction will require Network Rail to purchase a strip of land from retail park owners British Land.
This Google Map shows where the platform will be placed.
Note.
- The Forster Square Retail Park is in the North-East corner of the map.
- The glazed roof covers Platforms 1 and 2.
- There are trains in Platforms 1 and 3.
- Fitting in the new platform could be a bit tight.
Will the platforms be renumbered or will the new platform be called Platform 0?
Project Management Considerations
Consider.
- Bradford will be the UK City of Culture in 2025.
- British Land will want to have minimal disruption to the operation of their retail park.
For these reasons, all parties will want an early completion.
But as the site should have good access through the retail park, I could envisage that an early completion can be delivered by good project management.
How Many Platforms Will LNER Need?
Consider on the 1st of February 2024, four LNER trains visited the station.
- All trains were Class 801 trains.
- One train was a nine-car train and the others were a pair of five-car trains.
- Two trains used each of Platforms 1 and 2.
- LNER are planning to add five more trains per day (tpd), which will be a total of fourteen movements per day.
I suspect under normal operation, LNER could manage with one platform, as LNER’s movements are less than one per hour.
Conclusion
This new platform seems to be a good plan, that adds much-needed capacity for the short term and provides capacity for more services in the future.
