The Bay Platform At Greenford Station
These pictures show Greenford station.
I have some observations to make.
Electrification
Tests for the new battery-electric train would appear to be taking place soon, but there is no electrification or Vivarail/GWR Fast Charge system.
This leads me to the conclusion, that all charging will be done at West Ealing station.
What Length Of Train That Can Be Accommodated In Platform 2 At Greenford Station?
Consider.
- The two-car Class 165 train shown in the pictures is 47 metres long.
- FirstGroup’s test Class 230 train appears from a GWR video, to be three-cars, which would make it 54.663 metres long.
- The test Class 230 train would appear to be nearly eight metres longer, than the current train that works the route.
From the pictures it appears that there is sufficient space in the platform to accommodate the longer train.
Great Western Railway’s Battery Train Sets New Distance Record
The title of this post, is the same as that of this press release from Great Western Railway.
This is the sub-heading.
Great Western Railway’s innovative FastCharge battery trial has achieved another significant step – just days after laying claim to a battery train UK distance record without recharging.
These two paragraphs add more detail.
The train demonstrated its capability on Wednesday by travelling a UK record of 86 miles (138km) on battery power alone and without recharging.
Today the Class 230 battery train completed a 70-mile move from Long Marston to Reading Train Care Depot – using just 45 per cent of its battery capacity. GWR’s team of specialist engineers on board the train claim it could have travelled more than 120 miles on a single charge.
There is also this impressive video.
Note.
- In the video, the train is cruising at 36 mph.
- The top speed of the D78 Stock was 45 mph.
- The train looks in excellent condition.
This is a total game-changer for battery-electric trains in the UK.
The train makers, who have demonstrated battery-electric trains; Alstom/Bombardier, CAF, Hitachi, Siemens and Stadler will have to up their distances on battery power to at least 86 miles and possibly 120 miles, as who would want their new product to be outdistanced by second-hand forty-year-old upcycled London Underground trains?
I have some further thoughts.
The Trains Performance In The Real World
Dr. Simon Green, who is GWR’s Engineering Director, said this.
It’s also worth noting that in reaching the 86 miles on Wednesday, the train was operating in a real-world environment, at speeds of up to 60mph, stopping and starting over a hilly route, with elevation changes of up to 200m.
The train exceeded the 84 miles (135km) recorded by a Stadler Class 777 under test conditions in 2022 – believed to have been the greatest distance travelled by a battery train designed for the UK.
Note that the train was running at up to 60 mph.
Timings For The Mid-Cornwall Metro
This map shows the Mid-Cornwall Metro.
I have been looking at the Mid-Cornwall Metro and this service will share the Cornish Main Line with faster services between Par and Truro.
- Expresses and the Mid-Cornwall Metro will both stop at Par, St. Austell and Truro.
- Par and Truro is a distance of 19 miles.
- Expresses between Penzance and Plymouth take around 22-23 minutes to go between Par and Truro.
- This is an average speed of around 50-52 mph.
It looks to me, that there is scope for the Mid-Cornwall Metro and the express trains to run at similar speeds between Par and Truro.
- If the Mid-Cornwall Metro used Class 230 trains running on batteries, these trains should be fast enough to keep out of the way of the expresses.
- Par station has an island platform, where the Mid-Cornwall Metro uses one side (Platform 3) and expresses use the other (Platform 2).
Perhaps, if the timetable was something like this, it would give the best services to passengers.
- All expresses would use Platform 2, if they were stopping at Par station. The current track layout allows this.
- For Westbound passengers the Mid-Cornwall Metro would stop in Platform 3 and the express would stop in Platform 2, so that passengers going to beyond Truro on the Cornish Main Line could to the express on the other platform.
- Between Par and Truro, the Mid-Cornwall Metro would run a couple of minutes behind the express.
- Passengers for the Falmouth Branch could swap trains at Par on wait for the Metro at St. Austell or Truro.
- For Eastbound passengers, between Par and Truro, the Mid-Cornwall Metro would run a couple of minutes behind the express.
- At Par, the Mid-Cornwall Metro would stop in Platform 3 and the express would stop in Platform 2.
- The express would wait at Par for the Mid-Cornwall Metro.
- Passengers for Plymouth and London Paddington would change trains at Par for the express on the other platform.
- Passengers for the Newquay Branch on the express would swap trains at Par or wait for the Metro at St. Austell or Truro.
I suspect there are other patterns, but something like this will combine express services with the Mid-Cornwall Metro.
Simon’s Vision
Simon Green also says this about his vision of how the trains and the related FastCharge technology could be used.
GWR’s FastCharge technology has been designed to solve the problem of delivering reliable, battery-only trains capable of fulfilling timetable services on branch lines, eliminating the use of diesel traction and helping to meet the Government and wider rail industry’s target to reach net-zero carbon emissions by 2050.
The use of batteries for extended operation has typically been constrained by their range and meant widespread implementation has, until now, not been possible. It also negates the need for overhead electric lines which are expensive, time consuming to install and impact the landscape.
He’s judging the system as a whole, which is the only way to do it.
Where Could Class 230 Trains Be Used On The Great Western Railway?
These are a few ideas.
- Slough and Windsor & Eton Central – 2.8 miles – 3 cars – FastCharge at Slough
- Maidenhead and Marlow – 7.1 miles – 2 or possibly 3 cars – FastCharge at Maidenhead
- Twyford and Henley-on-Thames – 4.6 miles – 3 cars – FastCharge at Twyford
- Reading and Basingstoke – 15.4 miles – 3 cars – FastCharge at Basingstoke
- Weston-super-Mare and Severn Beach – 32.5 miles – 3 cars – FastCharge at Severn Beach
- Bristol Temple Meads to Avonmouth 8.9 miles – 2 cars – FastCharge at Avonmouth
Bourne End station, where there is a reverse may restrict the length of the service to Marlow.
GWR Trialling Transformative Ultra-Rapid Charging Train Battery
The title of this post is the same as that of this article on Rail Technology Magazine.
This is the sub-heading.
Great Western Railway (GWR) has begun trialling a potentially groundbreaking battery innovation called FastCharge. If the trial is successful, it is hoped that the technology could transform branch line services and accelerate the decarbonisation of the network.
This is the first paragraph.
This innovative system, which has been developed over three years, eliminates the need for diesel trains on branch lines by powering battery-operated units with ultra-rapid charging. The system boasts an impressive 2,000kW charging capacity, eight times more powerful than a Tesla Supercharger, allowing trains to fully recharge in just 3.5 minutes at West Ealing station, the trial’s first real-world location.
I took these pictures of the trial installation at West Ealing station, this morning.
Note.
- Platform 5 is used by the trains to and from Greenford station.
- Two sets of charging rails have been installed between the rails, in Platform 5.
- The rails in the charging rails could be aluminium. This would not be surprising, as it is a good electrical conductor.
- The two shorter outside charging rails could be connected together.
- The yellow parts of the charging rails are plastic, so are probably for warning purposes.
- Two white containers have been installed alongside the track.
In Great Western Railway Updates EHRT On Its Upcoming Operational Trial Of Fast Charge Tech, I described the components of the Fast Charge system in this paragraph.
The Fast Charge system consists of three key components: retractable charging shoe gear, which is mounted to the underframe of the train; short (4m) charging rails mounted between the underframe of the train; and the Fast Charge Battery Bank (FCBB) installed beside the track, acting as an energy buffer between the train and the grid.
The charging rails are clearly visible in my images and the Fast Charge Battery Bank is probably in the white containers.
These are my thoughts.
The Engineering Is Of A High Quality
Or it certainly appears so from the platform and in the pictures, that I took.
How Much Energy Will Be Taken On Board at Each Charge At West Ealing?
According to the Rail Technology Magazine article, the Fast Charge Battery Bank will have to supply 2,000 KW for 3.5 minutes to fully-charge the train at West Ealing station.
This is 7,000 KW-minutes or 117 KWh.
In D-Train Order For Marston Vale Confirmed, this is said about the batteries on a Class 230 train.
- The train has four battery rafts, each with a capacity of 106 kWh
- Range is up to fifty miles with a ten minute charge at each end of the journey.
- Range will increase as battery technology improves.
I wonder if the Class 230 train, that will run between West Ealing and Greenford, will only have one 106 kWh battery.
- This will be less weight and therefor better acceleration.
- 117 kWh in the Fast Charge Battery Bank will be sufficient to fully-charge the single battery.
- The route is only five miles for a round trip.
I can see costs dropping.
What Batteries Will Be Used In The Fast Charge Battery Bank?
I think there are four main possibilities.
- New lithium-ion batteries
- Refurbished second-hand electric vehicle batteries
- New lead-acid batteries.
- It might be possible to use supercapacitors
Note.
- Lead-acid batteries can lose charge in cold weather.
- Supercapacitors don’t care about the weather.
- The weight of lead-acid batteries would not be a problem in a stationary application.
If there is only one battery on the train, I can see the supercapacitors handling it.
What Voltage Is Used In The Charging Rails?
Consider.
- The Vivarail Class 230 trains are built from redundant London Underground D78 Stock trains.
- The D78 Stock trains were built to run on London Underground lines, when that had voltages of 0 and 630 VDC.
- So I wouldn’t be surprised if the trains were designed around this voltage.
- If the charging rails worked at 630 VDC, then to have a 2,000kW charger, this would mean a charging current of 3175 Amps.
This would explain the fat cables connecting the charging rails to the Fast Charge Battery Bank.
An alternative voltage to use could be 3,000 VDC, as some trains are built to this voltage and therefor the electronics and transformers must be available. This would reduce the charging current to 667 Amps, which might be able to use smaller cables.
It may come down to what is convenient for the output voltage of the batteries.
Why Are There Two Sets Of Charging Rails?
They are both shown in this image.
Note.
- The two sets of charging rails are about forty metres apart.
- The Fast Charge Battery Banks are another twenty metres further on.
It’s not the layout you’d expect for running a single two-car train running every half hour.
But could it be that two separate sets of charging rails can operate a more frequent service with this layout of charging rails?
Mid-Cornwall Metro Presentation – 9th February 2024
On Friday, I went to the Mid-Cornwall Metro presentation in the Victoria Hotel in Newquay.
These pictures give a flavour of the excellent presentation.
One thing that is difficult to put on paper is the overall enthusiasm for the project shown by representatives of Cornwall Council, Great Western Railway and Network Rail.
I believe that if this enthusiasm can be translated into action in the next couple of years, them this project can be delivered on time and on budget.
This link will show all my Mid-Cornwall Metro posts.
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.
Could A Heathrow And City Line Be Created?
In The New Step-Free Entrance At Euston Square Station, the following comment was added by Martin.
As said cutting the two new pedestrian tunnels from the existing platforms outside the existing brickwork MAY be less demanding than extending the platform tunnel, however I feel that extending the rail platforms would be a more future proof solution as done on the Elizabeth Line, in addition to reducing walking time to the Main Line with Stuff. I would like to see this as a precursor to extending platforms 5 & 6 at Baker Street west to a new entrance at Glentworth Street. With other improvements along the line over time. Enabling a new “Heathrow & City Line” connection utilising the Elizabeth Line from a rebuilt platform at Westbourne Grove.
I will now look at Martin’s various suggestions.
A Connection Between Elizabeth Line And the Hammersmith & City Line At Westbourne Park Station
The last sentence of the comment is.
Enabling a new “Heathrow & City Line” connection utilising the Elizabeth Line from a rebuilt platform at Westbourne Grove.
Note.
- Martin means Westbourne Park not Westbourne Grove.
This OpenRailwayMap shows the lines through Westbourne Park station.
Note.
- The blue tracks are the Hammersmith & City Line.
- The blue arrow on the Hammersmith & City Line indicates Westbourne Park station.
- The orange tracks are the four tracks of the Great Western Main Line and the two tracks of the Elizabeth Line.
- To the East of this map, the Hammersmith & City Line crosses under the other tracks, so it can access platforms on the North side of Paddington station.
This second OpenRailwayMap is an enlargement of the lines through Westbourne Park station.
Note.
- As before the blue tracks and blue arrow indicate the Hammersmith & City Line and Westbourne Park station.
- Orange Lines 1 to 4, which are numbered from the South, are the four lines of the Great Western Main Line.
- The other three orange tracks are labelled Line 5, Westbound and Eastbound and handle GWR local services and the Elizabeth Line.
- I would assume that Eastbound and Westbound Elizabeth Line services use the appropriately named track.
This Google Map shows Westbourne Park station, Great Western Road, the rail tracks and the nearby Westbourne Park bus garage.
Note.
- The London Underground roundel indicates Westbourne Park station.
- The two Hammersmith & City Line platforms stretch to the West of the station entrance.
- Westbourne Park bus garage lies to the North of the Great Western Main Line and Elizabeth Line tracks.
- There are around fifty white-roofed buses parked on the roof of the bus garage.
- The Eastbound Elizabeth Line track runs along the South side of the bus garage.
Looking at the last two maps, I suspect that a two platform station serving the two Elizabeth line tracks under and to the East of Great Western Road.
- It would be connected to the Hammersmith & City Line by a walkway on the Western side of the Great Western Road.
- There would be step-free access to the Hammersmith & City and Elizabeth Lines.
I took these pictures from the platforms at the current Westbourne Park station and as I walked to and from Westbourne Park bus garage.
Note.
- The bus garage is recent and was built as part of the Elizabeth Line construction.
- There are two Westbourne Park station buildings.
- One building serves the Hammersmith & City Line and the other could have served the tracks now used by the Elizabeth Line.
- The Westbourne Park station buildings need a lot of restoration.
- Could a bus interchange be developed?
I believe that a station that connected the Hammersmith & City and Elizabeth Lines could be built.
Leisure Market Boom? GWR’s Vision For Direct Bristol-Oxford Services
The title of this post, is the same as that of this article on Rail Magazine.
This is the first paragraph.
Great Western Railway has hopes on running direct services between Bristol Temple Meads and Oxford from September 14, subject to approval of its new trial proposal by the Department for Transport and Network Rail. The move is a test of growth in demand for leisure travel by train.
It is an interesting idea.
These are some points about the service, given in the article.
- The route will be via Swindon, Chippenham and Bath Spa.
- Fastest journey time would be 71 minutes.
- The route will be aimed at the leisure market.
- There will be two trains per day (tpd) in each direction on Saturdays.
This is GWR’s handy route map.
These are my thoughts.
Will The Trains Call At Didcot Parkway?
This OpenRailwayMap shows Didcot Parkway station and the large triangular junction, that connects Oxford to the Great Western Main Line.
Note.
- The red tracks are the Great Western Main Line.
- The blue arrow indicates Didcot Parkway station.
- Oxford station is about ten miles to the North.
- Chords in the junction allow trains to go between Oxford and Paddington and Oxford and Swindon, with or without a stop at Didcot Parkway station.
The article says that GWR has asked to run the following services.
- 1018 Bristol Temple Meads-Oxford – Would arrive at Oxford at 1129.
- 1155 Oxford-Bristol Temple Meads (via Didcot) – Would arrive at Bristol Temple Meads at 1306.
- 1518 Bristol Temple Meads-Oxford – Would arrive at Oxford at 1629.
- 1712 Oxford-Bristol Temple Meads – Would arrive at Bristol Temple Meads at 1823.
Note.
- I suspect that the 1155 will reverse at Didcot Parkway station.
- There is a two train per hour (tph) service between Didcot Parkway and London Paddington stations.
- It looks like the four services could be run by a single train shuttling up the Great Western Main Line.
Would it be sensible if all Oxford and Bristol trains called at Didcot Parkway station, so that travellers could use the London service to their advantage?
But, calling at Didcot Parkway station would slow the service as there would need to be a reverse.
What Class Of Train Would Be Used?
Consider.
- A Bristol and Didcot Parkway via Bath Spa service takes 55 minutes.
- This is an average speed of 71.1 mph over a distance of 65.2 miles.
- 24.4 miles at the Bristol end of the route is not electrified.
- 10.3 miles at the Oxford end of the route is not electrified.
- The four services can be run by a single train shuttling up the Great Western Main Line.
It looks to me, that a bi-mode train with good performance is needed.
So I suspect that a five-car Class 800 or Class 802 train will be used.
Will The Train Be Battery-Electric Powered?
This is an interesting possibility.
- An ideal route for a battery electric train, is surely one with a long electrified section in the middle, which can be used to fully charge the train’s batteries.
- The train would have to run for 48.8 miles on its own power at the Bristol end of the route.
- The train would have to run for 20.6 miles on its own power at the Oxford end of the route.
The data sheet for a battery-electric Class 800/802 train can be downloaded from this page on the Hitachi web site.
In a section on the page, which is entitled Intercity Battery Trains, this is said.
A quick and easy application of battery technology is to install it on existing or future Hitachi intercity trains. Adding 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. 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.
The range of 70 km is 43.5 miles, which would appear to be a little bit short to go from the end of the electrification at Chippenham to Bristol Temple Meads and back.
But various measures could be taken to make sure the train can handle the route.
- The regenerative braking strategy could be used to conserve battery power.
- A second battery could be added to the train.
- Methods to charge the train at Bristol Temple Meads could be installed.
As London Paddington and Bristol Temple Meads is an important route, I suspect that Hitachi and Great Western Railway have a strategy to handle trains from Chippenham and sending them back.
Could This Route Be A Trial Route For Battery-Electric Trains?
Consider.
- Hitachi and Great Western Railway wouldn’t want to introduce an unreliable train without full full testing.
- Trains can probably limp to either Stoke Gifford or Reading depots, after a battery failure.
- Great Western Railway could test a new route.
- A full test only needs one train.
- Passenger reaction to a battery-electric train can be assessed.
- Staff need to be trained.
- The route can be run by a standard bi-mode if required.
- It could be the world’s first high-speed battery-electric train.
- Enthusiasts would flock to have a ride.
Could this be a trial service to make sure everything goes right?
Great Western Railway Updates EHRT On Its Upcoming Operational Trial Of Fast Charge Tech
The title of this post, is the same as that of this article on Electric and Hybrid Rail Technology.
This is the sub-heading.
Great Western Railway’s senior program manager, Sonya Johns, speaks to Electric & Hybrid Rail Technology about the firm’s progress on developing ex-Vivarail Fast Charge technology for battery-powered trains, ahead of operational trials due to commence in 2024.
The article is a must-read as it describes the progress since First Group, acquired the assets and intellectual property of Vivarail and its Fast Charge battery train technology.
This paragraph describes the components of the Fast Charge technology.
The Fast Charge system consists of three key components: retractable charging shoe gear, which is mounted to the underframe of the train; short (4m) charging rails mounted between the underframe of the train; and the Fast Charge Battery Bank (FCBB) installed beside the track, acting as an energy buffer between the train and the grid.
This paragraph outlines the benefits of the system.
The Fast Charge system has several benefits, according to Johns, including high charging power, enabling the train to be recharged in around 10 minutes; a standard DNO connection, avoiding costly power supply upgrades; full automation, with no driver interaction required; low safety risk (the charging rails are never live unless fully covered by the train); and minimal disruption during installation, as the FCBB is manufactured offsite and the charging rails are attached to existing sleepers.
This sounds like a system, that has been designed by someone fed up with regulators saying no to innovative ideas.
Other points from the article include.
- The shoe gear has been designed to be easily installed on any rolling stock.
- The one-year trial of the Fast Charge technology and the Class 230 battery train on the West Ealing and Greenford line will commence in spring 2024.
- GWR will capture and analyze data during the trial to understand how the technology performs in different conditions.
The article finishes with this paragraph.
The work, according to GWR, is part of its commitment to reduce the carbon emissions of its train fleet with a view to removing all diesel-only traction from the network by 2040, in line with the Government’s Transport Decarbonisation Plan.
Adrian Shooter would have been pleased if he was here to see it.
Cardiff To Reading In A Class 387 Train
Returning from my trip to Cardiff yesterday, it wasn’t the normal Class 80x train, but a pair of Class 387 trains.
The timings from real time trains, weren’t as bad as some would have expected.
- Cardiff Central – 16.54 – 16:56
- Newport – 17:07 – 17:11
- Bristol Parkway – 17:29 – 17:32
- Swindon – 17:53 – 17:58
- Reading – 18:20 – 18:26
Note.
- The first time is the scheduled time and the second time is the actual time of the Class 387 trains.
- The schedule covers the 109.2 miles in 84 minutes, which is an average speed of 78 mph.
- The Class 387 trains covered the 109.2 miles in 90 minutes, which is an average speed of 72.8 mph.
I also arrived in Reading with three or so minutes to catch the Elizabeth Line train.
Are More Elizabeth Line Services Needed To Reading?
In a couple of instances, I’ve waited at Reading for nearly half-an-hour for an Elizabeth Line train.
Currently.
- The two Elizabeth Line trains take 53 minutes between Reading and Paddington.
- The two Great Western Main Line trains, that serve Didcot Parkway take 37 minutes between Reading and Paddington.
- The Great Western Main Line train, that serve Newbury take 25 minutes between Reading and Paddington.
Perhaps four trains per hour (tph) on the Elizabeth Line would be more convenient?
But services wouldn’t be as fast.
The Anonymous Widower
