More Trains To Carmarthen
The last time, I looked at the number of GWR trains to Carmarthen its Wikipedia entry, it was just a couple.
Today, one train per hour (tph) is shown between London Paddington and Swansea, with this supplementary information.
- 7 trains per day continue to Carmarthen, calling at Gowerton (limited), Llanelli, Pembrey & Burry Port, Kidwelly (limited) and Ferryside (limited)
- On Summer Saturdays, 2 trains per day run to Pembroke Dock, calling at all stations between Carmarthen and Pembroke Dock
In Regulator Approves New Grand Union Train Service From Carmarthen To London Paddington, I talked about the plans of Grand Union Trains to run five trains per day (tpd) between London Paddington and Carmarthen.
This would appear to give a total of twelve tpd between London Paddington and Carmarthen.
This page on the Crown Estate web site is entitled Celtic Sea Floating Offshore Wind, where this is said.
The Government has set an ambition to deliver up to 5GW of floating wind by 2030, with rapid expansion anticipated thereafter.
At The Crown Estate, we are committed to helping the UK achieve its net zero ambitions. To support this, we are excited to deliver a new leasing opportunity in the Celtic Sea for the first generation of commercial-scale floating offshore windfarms – unlocking up to 4GW of new clean energy capacity by 2035, kick-starting industry in the region, and providing power to almost four million homes.
We will be inviting full commercial scale projects up to 1GW, which may be developed in a phased or ‘stepping stone’ approach. Recognising the need to develop the UK supply chain and supporting infrastructure for this nascent technology, this approach is deliberately intended to provide opportunities for growth and investment. This will also facilitate the co-ordination of the necessary infrastructure, such as ports and grid connections, all of which are key to the sustainable development of the UK floating wind sector over the long term.
This leasing opportunity will provide the foundation for greater capacity in the future and help establish an exciting new industrial sector for the UK, creating opportunities for significant new investment in jobs, skills and infrastructure for the communities onshore.
It appears to me, that Great Western Railway and Grand Union Trains both believe that there will be large increase in demand for rail travel between London Paddington and Carmarthen and also along the South Wales Coast.
Grand Union Trains are also proposing the building of a new parkway station at Parc Felindre North of Swansea.
But then this area of South Wales and the Celtic Sea, has the four things needed for the development of up to 5 GW of offshore wind; a lot of wind, a large area of empty sea, steel and deep water ports to assemble all the floating wind turbines.
A Zero-Carbon High Speed Railway Between London Paddington And Carmarthen
Consider.
- The Great Western Railway between London Paddington and Carmarthen is 222.5 miles and trains take around three hours and fifty minutes, which is an average speed of 58 mph.
- Between Bristol Parkway and Reading stations, the operating speed is 125 mph.
- In South Wales, the operating speed is generally between 70 and 100 mph.
- Only the 77.4 miles between Cardiff Central and Carmarthen via Swansea is not electrified.
There is probably scope to increase the operating speed using digital signalling and by improving the track.
I would suspect that a time between London Paddington and Carmarthen of under three-and-a-half hours is possible.
The Range Of Battery-Electric Trains
Hitachi have not been specific about the zero-carbon range of their Intercity Tri-Mode Battery Train, which is described in this Hitachi infographic.
In Stadler FLIRT Akku Battery Train Demonstrates 185km Range, I talk about Stadler’s record-braking Battery-electric; Akku, which covered 185 km or 115 miles.
I suspect that Hitachi’s engineers and those at their battery suppliers; Turntide Technology will be ultra-competitive, so I wouldn’t be surprised that the zero-carbon range of the Hitachi train is very competitive to the Stadler FLIRT Akku.
A hundred mile range would allow electric services to be run on these routes.
- Cardiff and Carmarthen – 77.4 miles
- Chippenham and Bristol Temple Meads and return – 48.8 miles
- Chippenham and Bristol Western-super-Mare and return – 86.9 miles
- Swindon and Cheltenham Spa and return – 86.5 miles
- East Coast Main Line and Hull and return – 72.2 miles
- Plymouth and Penzance – 79.5 miles
- Taunton and Newbury – 89.6 miles
- York and Scarborough and return – 84.1 miles
I am fairly sure that Hitachi will aim for at least a hundred mile battery range for their Intercity Tri-Mode Battery Train.
- This would be competitive with other train manufacturers like Stadler and Siemens.
- They would handle a lot of important routes.
- With development they could probably handle Edinburgh and Inverness.
I can’t wait to have a ride.
One Of The Worst Train Journeys I’ve Had In The UK Since The 1960s
I started out with a simple objective, in that I intended to go to Cardiff Central station and then explore the Cardiff Valley Lines to look at the progress of the electrification. I had also arranged to possibly have a drink, with an old acquaintance at Rhymney station.
For the first time, I took the Elizabeth Line from Moorgate to Paddington to catch a long distance train. It is so much easier than taking the Underground.
I bought a Super Off Peak Return ticket to Cardiff Central station for £62.15 with my Senior Railcard.
This was the journey I took today.
- I left Paddington on the 10:18 train for Cardiff Central.
- The train arrived at Bristol Parkway at 11:34½.
- Real Time Trains says this about the rest of the journey. “This service was cancelled between Bristol Parkway and Cardiff Central due to a problem with signalling equipment (J3)”
- I was advised by a member of staff, that I wouldn’t be going to Cardiff in the near future and he advised taking a CrossCountry train to Bristol Temple Meads and then going back to London using my Return ticket.
- I left Bristol Parkway at 12:12¼ and arrived in Bristol Temple Meads at 12:20½, after taking the CrossCountry train.
- At Bristol Temple Meads to salvage something of a wasted day, I took a diversion to Severn Beach for the princely sum of £1.95 with my Senior Railcard, arriving back at Bristol Temple Meads at 14:48½.
- I then caught the next train to London, which turned out to be the 16:00, as both the 15:00 and 15:30 were cancelled due to an incident at Didcot.
- The train left Bristol Temple Meads at 16:03 and arrived at London Paddington at 18:00, which was twenty minutes late.
Note.
- I never got to Cardiff.
- If I’d waited at Bristol Parkway and caught the next train, I’d have got to Cardiff at 16:15¼, which would have been four hours later, than if the first train hadn’t been cancelled and had been on time.
I’ve just tried to phone Great Western Railway, but their Contact Us page only gives details of Facebook, Twitter and What’s App. I don’t use any of those!
Conclusion – Added On 5th June 2023
I just received an e-mail saying the cheque will be the post!
Great Western Railway Get Innovative
This article on Rail Advent, which is entitled Great Western Railway Trial New Long Weekender Ticket Between London Paddington, Bristol And South Wales, caught my eye.
This is the Long Weekender page on the Great Western Railway web site.
This seems to be the basic rule.
Leave on a Friday or Saturday, return on a Monday and save over 60% compared to an Anytime Return.
You can also apply your Railcard.
This sounds very useful to me.
As an example, I spent an enjoyable couple of days in Swansea, where I explored the area on the rail network. This could be made to fit in with one of these tickets, even if it meant buying a return from Cardiff.
I shall investigate further, as the website booking doesn’t seem to know about the Long Weekender ticket.
I visited Paddington this afternoon and asked one of those guys in a green uniform.
He told me that at the moment you have to buy them in the Booking Office and that they will be available on the web site.
He also thought they were a good idea.
There is also this post on Ian Visits, which is entitled GWR Launches “Long Weekend” Train Tickets.
Ian says this.
GWR added that if the trial of the Long Weekender proves successful, it will be extended to other parts of the network.
Does that mean GWR’s or the National network?
Cardiff Central Station’s New Entrance
As I passed through Cardiff Central station, I took these pictures of their new Southern entrance.
Although, it’s mainly for the car park, it may have its uses for me, as there is a ticket office to buy the Day Ranger ticket, I generally use to explore the valleys.
Will It Be Third-Time Lucky For Grand Union Trains In Wales?
It is three years since I wrote Grand Union Seeks ’91s’ To Cardiff and their proposal has not been accepted and the third iteration has been announced.
This article on Wales Online is entitled Independent Rail Firm Bids To Launch As Rival To Great Western On The Mainline From South Wales To London.
These are the introductory paragraphs.
An independent rail firm is hoping to launch a rival train service in Wales which they say will slash journey times between Carmarthen and London. Grand Union Trains is making a fresh bid to introduce an initial service in both directions between Cardiff and London on the existing Great Western line.
The company believes the move will “create passenger choice” and increase the number of trains available, with the hope that the service can be extended west in South Wales towards Carmarthen.
Other points in the article include.
- Swansea will be by-passed, which will speed up services to and from Llanelli and Carmarthen.
- A new Park-and-Ride station will be built by Grand Union at Felindre, which is to the North of Swansea.
- Services will stop at Llanelli, Cardiff Central, Newport, Severn Tunnel Junction and Bristol Parkway.
- When Cardiff Parkway opens, this will be an extra stop.
An article in the June 2022 Edition of Modern Railways, which is entitled Grand Union Bids For London To Carmarthen, gives extra details.
- Three classes.
- 2023 start for the service.
- Five return trains per day.
- Cycle provision.
- Vanload freight will be carried.
- Electric trains could start between London and Cardiff by 2023.
- In 2025, trains could be nine-car bi-modes.
- South Wales-based operation and maintenance.
- 125 full-time jobs created.
It certainly seems to be a comprehensive and well-thought out plan.
These are my thoughts and observations.
Felindre Station
Felindre station is named in Wikipedia as the West Wales Parkway station, where it is introduced like this.
West Wales Parkway is a proposed railway station north of Swansea, near to the boundaries of the neighbouring principal area of Carmarthenshire, and the villages of Felindre and Llangyfelach. The station is proposed to be situated at the former Felindre steelworks, near Junction 46 of the M4 and A48, and near Felindre Business Park and Penllergaer Business Park. The project is in the planning stages, as part of a wider Department for Transport proposal to re-open the Swansea District line to passenger traffic.
This Google Map shows where, it appears the Felindre station will be built.
Note.
- The Felindre Business Park in the North-West corner of the map, with a Park-and-Ride.
- The M4 running across the bottom of the map.
- The Swansea District Line runs East-West between the motorway and the Business Park.
It looks that the new station could be located on the South side of the Business Park.
According to Wikipedia, the station would cost £20 million to build.
- It would need a comprehensive rethinking of transport improvements in the Swansea area.
- But it could result in time savings on services between Carmarthen and Cardiff.
The Modern Railways article says this.
GU proposes to build the Felindre station near Swansea and invest in Severn Tunnel Junction station, where it says it will increase parking, provide direct access from the M4 motorway and improve passenger and staff facilities, backing up plans being evaluated by the Welsh Government for the station.
Grand Union is not a charity and does this indicate that a bank or infrastructure company is prepared to fund parking and the extra passengers pay the charges.
Rolling Stock
Wikipedia says that the rolling stock could be nine-car InterCity 225s hauled by Class 91 or Class 93 locomotives.
As the Class 93 locomotives are bi-modes, these would handle the Carmarthen and Cardiff leg.
The Modern Railways article says this.
Trains could start between Cardiff and London Paddington as early as May 2023 if electric only, with services extended west around two years later with new bi-mode trains in up to nine-car formations.
Would a new Class 93 locomotive count as a new bi-mode train?
I suspect the new locomotive would be more affordable, than a new bi-mode train.
Vanload Freight
This is an interesting idea and it follows similar thinking to Royal Mail’s latest ideas, that I wrote about in Royal Mail Rolling Back The Years To Put More Post On Trains.
One coach could be a nice little earner, if it were modified to carry roller cages, that were loaded and unloaded at the end of the route.
One advantage of the InterCity 225s is that they are 125 mph trains, so that this will be high speed freight.
Timings
Consider.
- A GWR Carmarthen and London service takes three hours and 47 minutes.
- This includes a nine-minute reverse at Swansea.
- GWR makes seven more stops than Grand Union will.
- GWR does seven diesel stops, whereas Grand Union will only do two.
I would estimate that Grand Union will be under three hours and thirty minutes.
Carmarthen Station
This Google Map shows Carmarthen station.
Note.
- The station has two platforms.
- There are certainly pictures of the station with an InterCity 125 in the station.
These pictures show the station.
I suspect that the station will be upgraded to accommodate Grand Union.
Rrenewable Energy Developments In South West Wales
In Enter The Dragon, I talked about renewable energy developments in South West Wales.
I used information from this article on the Engineer, which is entitled Unlocking The Renewables Potential Of The Celtic Sea.
The article on the Engineer finishes with this conclusion.
For now, Wales may be lagging slightly behind its Celtic cousin to the north, but if the true potential of the Celtic Sea can be unleashed – FLOW, tidal stream, lagoon and wave – it looks set to play an even more prominent role in the net zero pursuit.
The Red Dragon is entering the battle to replace Vlad the Mad’s tainted energy.
South West Wales could see a massive renewable energy boom.
The Railways To The West Of Carmarthen
This map from OpenRailwayMap shows the rail lines to the West of Carmarthen.
There are three main branches to Fishguard, Milford Haven and Pembroke Dock.
I can see the railways becoming increasingly important in supporting the growing renewable energy in the area.
- There would be more frequent services.
- Services would tie in with London and Cardiff trains at Carmarthen.
- Closed stations could be reopened and new ones built.
It may also be possible to bring in large components needed by the renewable energy industry.
Conclusion
I feel that Grand Union have seen the opportunities presented to a frequent Carmarthen and London service and have grabbed them with both hands.
Open Access Operators And The Lumo Model
In the UK, there are only three established Open Access operators, who run UK train services.
- Grand Central
- Heathrow Express
- Hull Trains
From the 25th of October, they will be joined by Lumo.
We probably don’t think of Heathrow Express as an Open Access operator and as it is effectively a short distance special service with new trains between Heathrow and Paddington, it has its own business model, that may or may not survive.
But how will Lumo and their bold new business model affect Grand Central, Hull Trains and any future Open Access operators?
Grand Central Trains
Grand Central is a well-established Open Access operator.
- They run services between London King’s Cross and Bradford Interchange, Sunderland and several other convenient en-route stations.
- They are owned by Deutsche Bahn.
- They also regularly seem to apply for new routes and extra services.
But they have a big problem fast catching up on them; they have a diesel-only fleet and need to decarbonise.
I also think that all express passenger services on the East Coast Main Line will at some date need to be run by 140 mph trains capable of running with full digital signalling and a degree of Automatic Train Operation.
In Lumo: Why Won’t The New Train Service Stop At Yorkshire Stations?, I said that to continue to be successful, they probably need to embrace the Lumo model and acquire new trains.
I will repeat what I said in the related post.
This would entail.
- The ten diesel Class 180 trains would be replaced by new electric trains.
- The trains would need a 140 mph capability under digital signalling to fit in with the plans of Network Rail, LNER and Lumo to create a top-class high-speed high-capacity East Coast Main Line.
- The trains would need a battery capability as Grand Central’s routes are not fully electrified.
- They could copy Lumo’s green marketing philosophy, ticketing and catering offering.
As to the trains, I’m sure that Hitachi could offer a version of their Intercity Tri-Mode Battery Train, the specification of which is shown in this Hitachi infographic.
The trains would need a range of fifty miles on battery-power.
I have some other thoughts.
Financing
If you look at the finances of decarbonising Grand Central, they would need a new fleet of ten trains, which as Lumo’s fleet of five trains are reported to be costing £100 million, so that figure can be at least doubled.
There would also be costs for the two charging systems at Bradford Interchange and Sunderland. But at least there are several possible solutions for charging systems, so the price will probably not be more than a few million, if that.
Will Deutsche Bahn be prepared to stump up the extra finance?
A Service To Cleethorpes
In the Wikipedia entry for Grand Central, there is a section which is entitled London Kings Cross to Cleethorpes, which outlines a proposed service.
- It would split and join with the London King’s Cross and Bradford service at Doncaster.
- It would call at Crowle, Scunthorpe, Barnetby, Habrough and Grimsby.
- Doncaster and Cleethorpes is 52.1 miles and should be in range of a Battery-electric train with a charging system at Cleethorpes.
Using current times from LNER and TransPennine Express, I estimate that Hitachi Intercity Tri-Mode Battery Trains could travel between London and Cleethorpes in around two hours and twenty minutes.
With digital signalling on the East Coast Main Line to the South of Doncaster, the overall time could be much closer to two hours.
This could be a very viable service with battery-electric trains capable of running at 140 mph on the East Coast Main Line and for sixty miles at 100 mph on battery power.
Maximising The Use Use Of Train Paths By The Use Of Splitting And Joining
The proposed service to Cleethorpes is a classic use of splitting and joining, which enables two separate services to run a large part of their routes together.
- On the East Coast Main Line, it means that maximum use can be made of the paths available.
- Splitting and joining is part of the specification for the Hitachi trains and they do it automatically in under two minutes.
- LNER are already talking about using the technique to serve various destinations from Leeds.
I wouldn’t rule out Grand Central’s two services working as a pair between London King’s Cross and Doncaster, where they would split and join.
Conclusion On Grand Central Trains
Decarbonisation with high-speed battery-electric trains could ensure the future of Grand Central Trains.
Hull Trains
Hull Trains is another well-established Open Access operator.
- They run services between London King’s Cross and Hull and Beverley.
- They have a fleet of five bi-mode Class 802 trains.
- The company is part of First Group.
Hull Trains don’t have the decarbonisation problem of Grand Central Trains, as I suspect Hitachi will come up with a solution to turn Class 802 trains into a battery-electric train with a range of perhaps seventy miles on battery power.
- Beverley and Temple Hirst junction is a distance of 44.3 miles and is the only section of the route without electrification.
- Charging of the batteries will be needed at the Eastern end and probably would be best handled by a short length of electrification in Hull station or between Hull and Brough stations.
The Class 802 trains are also ready for updating to run under the new digital signalling of the East Coast Main Line.
First Harrogate Trains
First Harrogate Trains was a subsidiary of Hull Trains, which hoped to run the following services.
- London King’s Cross and Harrogate via York
- London King’s Cross and Cleethorpes via Peterborough, Spalding and Lincoln
Both these services could be run in conjunction with the current service with an appropriate split and join.
Conclusion On Hull Trains
As both Hull Trains and Lumo share London King’s Cross and are both owned by First Group, I would expect that both train operators would share some services, methods and ideas.
There may be advantages if Hull Trains’s Class 802 trains and Lumo’s Class 803 trains could run each other’s services.
Grand Union
Grand Union is a prospective open access operator who are proposing to operate train services from England to Wales and Scotland.
They are proposing two services.
London Paddington and Cardiff Central via Reading, Bristol Parkway, Severn Tunnel Junction, Newport and Cardiff Parkway, with a possible extension later to Swansea andLlanelli or Carmarthen.
London Euston and Stirling via Milton Keynes Central, Nuneaton, Crewe, Preston, Carlisle, Lockerbie, Motherwell, Whifflet, Greenfaulds and Larbert.
Note.
- London Paddington and Cardiff Central is fully electrified, but there is no electrification West of Cardiff Central.
- Cardiff Central and Swansea are 45.7 miles apart.
- London Euston and Stirling is fully electrified.
Currently, the rolling stock for both services is proposed to be a tri-mode Class 93 locomotive hauling a rake of Mark 4 coaches and a driving van trailer.
The locomotive should be capable of handling the routes to Stirling and Cardiff using the electrification alone.
When the Cardiff route is extended, Grand Union would intend to use Class 802 trains, which could be fitted with batteries to serve Swansea, where the batteries would be charged.
There is no sign as yet, that the Office of Rail and Road have approved any of their possible services, but both services might be improved with some Lumo-style thinking.
Alliance Rail Holdings
Alliance Rail Holdings, which is a sister company to Grand Central, is ultimately owned by Deutsche Bahn, seems to have several ideas for new services, but only seems to have got approval to one.
They were given approval some years ago to run a service between London Euston and Blackpool North.
- Calls would be made at Poulton-le-Fylde, Kirkham and Wesham, Preston, Nuneaton and Milton Keynes Central.
- There will be six trains per day.
- Trains would be InterCity 225 trains.
- The approval is for seven years from 2018.
But because of the pandemic it hasn’t run.
Conclusion
The Lumo model will affect all these services.
Thoughts On Train Times Between London Paddington And Cardiff Central
I went to Cardiff from Paddington on Tuesday.
These were the journey details.
- Distance – Paddington and Cardiff – 145.1 miles
- Time – Paddington and Cardiff – 110 minutes – 79.1 mph
- Time – Cardiff and Paddington- 114 minutes – 76.4 mph
There were four stops. Each seemed to take between two and three minutes.
I do feel though, that the trains are still running to a timetable, that could be run by an InterCity 125.
I watched the Speedview app on my phone for a lot of both journeys.
- There was quite an amount of 125 mph running on the route.
- Some stretches of the route seemed to be run at a line speed of around 90 mph.
- The Severn Tunnel appears to have a 90 mph speed.
- Coming back to London the train ran at 125 mph until the Wharncliffe Viaduct.
These are my thoughts.
Under Two Hour Service
The current service is under two hours, which is probably a good start.
Improving The Current Service
It does strike me that the current timetable doesn’t take full advantage of the performance of the new Hitachi Class 80x trains.
- Could a minute be saved at each of the four stops?
- Could more 125 mph running be introduced?
- Could the trains go faster through the Severn Tunnel?
- If two trains per hour (tph) were to be restored, would that allow a more efficient stopping pattern?
- The route has at least four tracks between Paddington and Didcot Parkway and the Severn Tunnel and Cardiff.
I would reckon that times of between one hour and forty minutes and one hour and forty-five minutes are possible.
These times correspond to average speeds of between 87 and 83 mph.
Application of In-Cab Digital Signalling
Currently, a typical train leaving Paddington completes the 45.7 miles between Hanwell and Didcot Parkway with a stop at Reading in 28 minutes, which is an average speed of 97.9 mph.
This busy section of the route is surely an obvious one for In-cab digital signalling., which would allow speeds of up to 140 mph.
- Services join and leave the route on branches to Bedwyn, Heathrow, Oxford and Taunton.
- The Heathrow services are run by 110 mph Class 387 trains.
- There are slow lines for local services and freight trains.
If an average speed of 125 mph could be attained between Hanwell and Didcot Parkway, this would save six minutes on the time.
Would any extra savings be possible on other sections of the route, by using in-cab digital signalling?
I suspect on the busy section between Bristol Parkway and Cardiff Central stations several minutes could be saved.
Would A Ninety Minute Time Between Paddington And Cardiff Be Possible?
To handle the 145.1 miles between Paddington and Cardiff Central would require an average speed including four stops of 96.7 mph.
This average speed is in line with the current time between Hanwell and Didcot Parkway with a stop at Reading, so I suspect that with improvements to the timetable, that a ninety minute service between Paddington and Cardiff Central is possible.
It may or may not need in-cab digital signalling.
My Control Engineer’s nose says that this signalling upgrade will be needed.
Would A Sixty Minute Time Between Paddington And Cardiff Be Possible?
A journey time of an hour between Paddington and Cardiff Central would surely be the dream of all politicians the Great Western Railway and many of those involved with trains.
To handle the 145.1 miles between Paddington and Cardiff Central would require an average speed including four stops of 145.1 mph.
It would probably be difficult to maintain a speed a few mph above the trains current maximum speed for an hour.
- How many minutes would be saved with perhaps a single intermediate stop at Bristol Parkway station?
- Perhaps the Cardiff service could be two tph in ninety minutes and one tph in sixty minutes.
- Full in-cab digital signalling would certainly be needed.
- Faster trains with a maximum speed of up to 155-160 mph would certainly be needed.
- There may be a need for some extra tracks in some places on the route.
A journey time of an hour will be a few years coming, but I feel it is an achievable objective.
The Extended Route To Swansea
Cardiff Central and Swansea is a distance of 45.7 miles
A typical service takes 55 minutes with three stops, at an average speed of 49.8 mph.
This would be an ideal route for a Hitachi Intercity Tri-Mode Battery Train, which is described in this Hitachi infographic.
It would probably be needed to be charged at Swansea station, to both enable return to Cardiff Central or extend the service to the West of Swansea.
Conclusion
Big improvements in journey times between Paddington and Cardiff Central are possible.
One Freight Train Overtaking Another In Cardiff Central Station
I took these pictures as one freight train overtook another, as they passed to the West, through Cardiff Central station.
You don’t see it often in the UK.
Especially in a station.
The New Platform 8 At Cardiff Central Station
It’s been a long time, since I’ve been to Cardiff station and it now has a new platform on the South sisw, which is numbers 8.
It now looks like Cardiff Central has three platforms 6, 7 and 8 for most of the local services.
This Google Map shows the new South entrance.
Note.
- The actual entrance is the five-sided building at the bottom of the map.
- Platform 8 is in front of this building.
- Platforms 6 and 7 are either side of the island platform..
- The three platforms are connected by a subway.
It doesn’t appear that the platforms are electrified at this time.
Cardiff Bridge Avoids £40m Demolition Thanks To Electric Resistant Paint
When I first saw this headline on this press release on the Network Rail web site, I felt it sounded too good to be true.
This is the introductory paragraph.
In a world first, electric resistant paint combined with voltage-controlled clearance (VCC) has helped make a Victorian railway bridge usable by new electric trains, avoiding weeks of passenger disruption and train delays in the process.
I think this is the bridge.
Note.
- The South Wales Main Line runs East-West, with Cardiff Central station to the West.
- The track between Cardiff Queen Street and Cardiff Bay stations runs North-South, with Cardiff Queen Street station to the North.
- The two rail lines cross over a canal.
- The site is surrounded by new high-rise buildings.
- The clearance been the bridge and the main line underneath appeared to be too tight for electrification to be fitted.
But by using the combination of technologies, as stated in the introductory paragraph, Network Rail were able to squeeze the wires through, which didn’t need the bridge to be demolished and rebuilt on a tricky site.
I can see that railways and other places, where high-voltage cables are close to metal structures, will be able to find lots of uses for Southampton University’s “Magic Paint”
The Anonymous Widower
