If This Is The End For The £1.3bn M4 Relief Road, Radical Thinking Is Needed
The title of this post is the same as that of this article on Wales Online.
The article is a good analysis of one of South Wales’ major transport problems; How do you relieve capacity on the ageing M4 around Newport?
I haven’t been on that section of road for perhaps twenty years or even longer, but I can’t ever remember the road, not being full of traffic.
Abolition Of Tolls Not The Smartest Move
This is a subsection of the article about the abolition of tolls on the Severn Crossing, where this is one sentence.
The abolitions of tolls, as predicted, have already driven a 20% rise in traffic levels on the existing M4, which will only put more pressure on its resilience.
Any sensible person could have told you that.
Surely, the extra capacity should have at least been planned before the tolls were abolished.
But then politicians like buying votes with unsustainable decisions that benefit their electorate.
As another example, look at the problems, Sadiq Khan’s fare freeze has caused Transport for London. But then you can’t expect a lawyer and politician to get their sums right. My late wife was a lawyer and many of our friends in Suffolk were in the same profession. Few had any clue about handling numbers properly.
£100m Train Test Complex Plans For Neath Valley Backed
The title of this post is the same as that of this article on the BBC.
This much-needed project, which some wag has called Project Hornby, seems to be moving on..
This brief description is from the article.
The complex would allow trains to be tested on special tracks – laid out on 4.5 mile (7.3km) and two mile (3.1km) ovals – at speeds of up to 100mph (160kph).
It will certainly test their ability to go round corners.
Hopefully, the test track will shorten the time, it takes new and updated trains into service.
Global Centre Of Rail Excellence Takes A Step Forward With Formal Partnership Arrangements
The title of this post is the same as that of this article on Wales Online.
This is the first two paragraphs.
The planned £100m Global Centre of Rail Excellence on the border of Neath Port Talbot and Powys will take a step closer to reality when councillors meet to formalise partnership arrangements next week.
Plans for the centre which were announced by the Welsh Government last summer involve a new facility to test trains in the UK.
In my view this centre is much needed, so that trains manufactured and modified in the UK, can be adequately tested in as short a time as possible.
Sending trains to be tested half-way across Europe, as currently sometimes happens, is not an efficient method of getting trains into service.
Severn Toll Change
The title of this post is the same as that of a short article in the February 2019 Edition of Modern Railways.
This is the first paragraph.
There are concerns that the removal of toll charges on the M4 Severn Crossings on 17 December could result in a loss of rail freight traffic to road. The toll, for westbund vehicles only, was £16.70 per Heavy Goods Vehicle last year. It had been reduced from £20 in January 2018, when VAT ceased to be levied because the motorway bridges had passed from private to public ownership.
It now appears that it is now cheaper to get wine from Felixstowe to a warehouse in Avonmouth, by using a train to Cardiff and then using trucks, than by using a train to Bristol and a shorter truck journey.
Surely, the longer journeys by both diesel truck and probably diesel train, creates more carbon dioxide.
Obviously, the UK and Welsh Governments didn’t assess the carbon emission consequences of abolishing the tolls on the Severn Bridges.
I also wonder, if more people will now drive between South Wales and England, because of the incentive of a toll-free crossing, which will further increase carbon-dioxide emissions.
Cost Of Widening The Last Section Of The A465 Will Be More Than The Entire South Wales Metro
The title of this post, is the same as that of this article on Wales Online.
The article is a good example of comparing costs between road and rail and is well worth a read.
£18.75m Halton Curve Project Delayed A Further Six Months
The title of this post is the same as that of this article on Rail Technology News.
I could just blame politicians for the latest project to be delayed, but it is not wholly their fault.
Train companies all over the UK, Europe and the Rest of the World have been ordering new trains at an unprecedented rate for the following reasons.
- The replacement of clapped-out trains like Pacers.
- Extra trains to provide extra services.
- Faster trains to provide faster services.
- Bigger or longer trains to provide more capacity.
- New electric trains for newly electrified routes.
- New trains often cost less to service and maintain.
- Affordable finance for quality new trains is available in billions of pounds, euros and dollars of all kinds.
In addition a lot of trains are being updated with new technology like signalling, automatic systems and high-technology interiors.
All of these factors mean that there is a high level of train testing that needs to be done.
These test tracks are in Europe and listed in Wikipedia.
- Czech Replublic – Velim railway test circuit – Two circuits of 4 and 13 km.
- France – Centre d’essais ferroviaires – Near Alstom Valenciennes factory site in Raismes, includes 2.75 km for testing at 100 km/h, a 1.85 km loop for endurance testing at 80 km/h, and a loop for testing driverless trains.
- Germany – Test and validation centre, Wegberg-Wildenrath – Near Wildenrath in North Rhine-Westphalia, Germany. Several loops of standard gauge and metre gauge track with various electrification systems.
- Poland – Test Track Centre near Żmigród – Operated by Warsaw Railway Institute. 7.7 km standard gauge loop, 160 km/h maximum allowed speed.
- Romania – Railway Testing Center Faurei – Total length of lines: 20,2 km, maximum speed 200 km/h.
- United Kingdom – Old Dalby Test Track
- United Kingdom – High Marnham Test Track
Note that Italy and Soain, who build substantial numbers of trains, don’t have a specialist testing centre.
I have read somewhere that each individual train has to be run for so many hours before it can be certified for service.
Consider
- Bombardier is building 412 Aventras with lengths between three and ten cars.
- CAF is building trains for Calodonian Sleeper, Keolis Amey Wales, Northern, TranPennine Express and West Midlands Trains.
- Hitachi is building 182 Class 800/801/802 trains with length of five or nine cars.
- Hitachi is building 80 Class 385 trains with lengths of 3/4 cars.
- Siemens are building trains for Govia Thameslink Railway.
- Stadler is building trains for Greater Anglia, Keolis Amay Wales and MerseyRail.
I haven’t done a detailed calculation must it must be at least 700 trains.
In addition there are various rebuilt and existing trains that will need to be tested.
- ScotRail’s shorterned InterCity 125s
- Porterbrook’s Class 769 trains.
- Vivarail’s Class 230 trains.
- Alstom’s Class 321 Hydrogen trains.
- Crossrail Class 345 trains need further testing.
And there will be new orders for the following franchises and lines.
- East Midlands.
- London Underground Piccadilly Line.
- South Eastern
- West Coast Alliance
I haven’t done a detailed calculation but we must be talking of nearly a thousand new trains of which probably six hundred will be delivered in the next five years.
I’m no expert, but I feel that two short test tracks and short lengths of improvised test tracks in factories, isn’t enough to test all these trains and certify them for service.
I should also blow my own trumpet and I know that when I wrote project management software, I was probably the best programmer in the World, at automatically scheduling resources.
So I tend to know, an impossible scheduling problem, when I see one!
Conclusion
We do send trains to Europe to specialist centres like the one at Velim in the Czech Republic. But these centres are also used by other European manufacturers.
I am led to the inevitable conclusion, that we need more train testing facilities, in both the UK and mainland Europe.
The Welsh Government has come to the same conclusion and are planning a test track at Neath, which I wrote about in £100m Rail Test Complex Plans For Neath Valley.
What would help, would be if Chris Grayling oiled a few wheels with some money. It might even result in some Continental trains coming to Wales for specialist testing like curing them of dracophobia.
I would also have felt that CAF would be happy with a test track fifty miles away from their new factory in Newport.
Come on, Wales! Fire up the dragons and get started!
First D-Train With Transport for Wales In March 2019
The title of this post, is the same as that of this article on Rail Magazine.
This is the first paragraph.
The first Class 230 D-Train for Transport for Wales should be ready by March 2019, with all five in traffic from May 2019.
There are also other details.
The Train Formation
More details are given about the formation of the Class 230 trains.
- The trains will be three cars.
- The driving cars will have batteries.
- The centre car will have four generators.
When the trains were D78 Stock on the London Underground, they ran as a six-car train formed of two half-trains containing.
- DM – Driving Motor
- T – Trailer
- UNDM – Uncoupling Non-Driving Motor
The two UNDM cars were coupled together, to form the six-car train.
So is the formation of a Class 230 train as follows?
- DM – Driving Motor with battery
- T – Trailer with four generators
- DM – Driving Motor with battery
I would suspect that the DM cars are identical.
Regenerative Braking
The trains will have regenerative braking, where the energy recovered will be stored in the batteries.
In the D78 Stock, the Trailer car wasn’t motored, so unless motors are fitted in this application, the two Driving Motor cars can almost be considered two identical battery locomotives with regenerative braking, that are solely responsible for moving the train.
The Trailer Car With Power
The Trailer Car in the middle of the train contains the four generators.
The Wikipedia entry for the Ford Duratorq engine, has a section for a 3.2 litre diesel engine, where this is said.
The 3.2 is an I5 engine used in the Ford Transit, the Ford Ranger, Ford Everest, Mazda BT-50 and the Vivarail D-Train.
The standard engine has a rating of 200 hp or 150 kW.
The Class 230 train would appear to have an installed power of 600 kW.
Interiors
The article says that everything the passenger will see inside the train is new!
Performance
This is a quote from Tristan Guyard of Transport for Wales.
On the Conwy Valley and Wrexham – Bidston routes, ‘230s’ will be quicker than most other new trains built in the UK at the moment. This is because of the high proportion of motored wheels and the use of batteries to provide additional power. When these trains come into service, we will be able to improve journey times and have a more flexible timetable as soon as 2019.
The Conwy Valley Line seems a stiff route, which might get a better service with a more powerful train.
The Wrexham-Bidston route currently takes 56 minutes to go South and 58 minutes to go North, which probably makes timetabling a half-hourly service a difficult job.
Will the Class 230 trains offer enough extra performance for these services?
Perhaps this is why they have four diesel power packs.
We will find out next year, what is the toughness of these remanufactured London Underground trains!
Thoughts On The Traction System
How Does The Power Compare To Other Trains?
How powerful is the 600 kW in the Class 230 train?
By comparison. a two-car Class 156 train, has 860 kW of diesel power.
On the other hand the three-car Class 230 train has regenerative braking using batteries.
Is The Class 230 Train A Serial Hybrid?
In a serial hybrid vehicle, a power source like a diesel engine charges the battery and the battery drives the vehicle and powers internal systems.
The classic serial hybrid vehicle is a New Routemaster bus, which is powered by a 138 kW diesel engine.
In this bus., the engine starts and stops to keep the energy in the battery within a particular range.
It is a very simple control system and is regularly used in many applications, where water or temperature levels are to be kept within range.
The layout of the Class 230 train with a central power car could easily provide power to the batteries in the two Driving cars.
The train’s control system would switch the engines on and off automatically as required.
If two diesel generators supplied the battery in each Driving Car, the train could even be considered a double serial hybrid.
So this should make the train reliable, as most components of the drive-train are duplicated.
Conclusion
I sometimes feel that the Class 230 train could end up as a heroic design failure.
But then the oldest trains in service on the UK’s rail network are the London Underground 1938 Stock on the Island Line.
London Underground rolling stock seems to have a longevity, that other trains seem to have been built without!
Or is it that as the elderly fleets of the Glasgow Subway, Merseyrail and the Northern City Line seem to keep soldiering on, that spending a large proportion of your working life underground, is good for trains?
£100m Rail Test Complex Plans For Neath Valley
The title of this post, is the same as that of this article on the BBC.
This is the first three paragraphs.
Plans for a £100m rail testing complex to work on next generation train technology have been revealed in south Wales.
It is at an early stage but it could be built on the site of a mothballed opencast mine in Neath Port Talbot.
The preferred option would be to site it at the mothballed opencast mine at Nant Helen near the border with Powys and at the coal washery site next door at Onllwyn, which is still operational.
This Google Map shows the massive open-cast mine near the village of Onllwyn.
Note the rail connection at the Northern side of the mine.
Onllwyn has a Wikipedia entry, which says this.
With over 200 years of coal mining behind it, the parish was once home to five pits that employed hundreds of men. Now all that remains is a coal washery and coal processing plant. On the route of the former Neath and Brecon Railway, a freight only routes exists to the coal washery from the South Wales Main Line at Neath.
So at least it’s swapping an old industry, with one that could have a very sparking future.
As I said in Talgo Explores Options For Building UK Test Track.
So perhaps we do need another convenient test track!
The site would be even more convenient, if the South Wales Main Line were to be electrified, through Neath to Swansea.
What Is It With The Welsh And Batteries?
If ordering two fleets of rail vehicles with batteries, that I wrote about in The Greening Of The Valleys, KeolisAmey Wales have now gone and ordered a third fleet for North Wales.
This article in the Railway Gazette is entitled Vivarail D-Trains For Wales & Borders.
This is the first paragraph.
Incoming Wales & Borders franchisee KeolisAmey is to take delivery of five three-car Class 230 D-Train diesel-battery multiple-units from Vivarail, which is to produce them using the bogies and aluminium bodyshells of withdrawn London Underground D78 metro trains.
Note that they are described as diesel-battery trains.
The article says the Class 230 trains will be used on these lines.
- The Borderlands Line between Wrexham and Bidston.
- The Conwy Valley Line.
- Between Chester and Crewe stations.
Five trains have been ordered, but I suspect it will eventually be more.
I believe that this picture shows a property of the Class 230 train, that would be ideal for Welsh routes or any other scenic lines.
They have large windows and get the interior design right and they could become an iconic way to fill a difficult niche market.
- A reliable hourly or half-hourly service on a remote line.
- A quality interior with everything customers expect like a fully-accessible toilet, wi-fi and power sockets.
- Space for bikes, buggies, babies and wheel-chairs.
- Step-free entry between train and platform was possible at some stations on the District Line and I suspect that many stations could be made, so that wheelchairs and buggies could just roll across.
- The ability to be serviced remotely.
Note that the train is fitted with toilets from Cwmbran in South Wales.
Did Transport for Wales say, that if you fitted Welsh toilets, we’ll buy a few trains?
I suspect though, that they are much better toilets, than those I saw as a child in castles like Caernarfon, Conway and Harlech, where the inhabitants in the Middle Ages must have been quick on the job to avoid the getting shot with arrows, where it would hurt!
I suspect constipation was rare in those days!
Seriously though, here’s a video of the Class 230 trains for Wales.
This video comes from this article in this article on Wrexham.com.
How Do The Trains Work?
I obviously don’t know exactly, but I suspect the method of operation is very similar to that of some of the advanced hybrid buses, like a new Routemaster.
Each of the diesel engines have a generator, which produces electricity. This can either be fed directly to the traction motors to power the train or stored in the onboard battery.
The train’s control system manages the power and chooses, whether traction power comes from the diesel engine or the battery.
This means that the diesel engines don’t have to work all the time.
Every Pair Of Pictures Tell A Story
This picture on the Rail Technology Magazine website shows a Greater Anglia Class 755 train.
And this picture on the Global Rail News website shows one of the new trains for Transport for Wales.
It is captioned “A Tri-mode unit on the Rhymney Line”.
On another report it is captioned “How a KeolisAmey tram-train will look”.
All trains look very similar and I’m pretty certain that Wales will be getting some Class 755 trains.
Class 755 Trains
Class 755 trains will have the following characteristics.
- 100 mph operating speed.
- Able to work on 25 KVAC overhead electrification
- Able to work using an onboard diesel power-pack.
- Three or more passenger cars.
- Ability to be lengthened by adding extra cars as required.
- Lots of power.
They would be ideal replacements for the current Class 175 trains, as the performance would appear to be similar.
They would also be ideal for services on the following routes.
When running around Birmingham, Cardiff, Crewe, Liverpool and Manchester, they would be able to use the electrification.
So are Keolis/Amey going for a predominantly uniform fleet of perhaps three-car and four-car Class 755 trains outside of the Cardiff Valley Lines, just as Greater Anglia used these trains on their routes without electrification North of Cambridge and Ipswich?
The Borderlands Line
The interesting route is the Borderlands Line between Wrexham Central and Bidston stations.
Currently, to get to and from Liverpool, there is a need to change trains at Bidston.
Merseyrail‘s new Class 777 trains are being built by Stadler.
- They will link Bidston station to Liverpool, where they will call at several stations in a single-track loop tunnel.
- The trains have been designed to work under battery power.
- Both classes of train are likely to be very similar under the skin.
So to eliminate the time-wasting change of train at Bidston station, I wonder if Stadler have designed the Class 755 and Class 777 trains, so that they can both run in the loop tunnel.
The additions needed to the Welsh Class 755 trains, over the Greater Anglian versions would be.
- Ability to use Merseyrail’s third rail electrification.
- Clearance to run in the tunnel with diesel onboard.
- Ability to evacuate passengers in the tunnel, in an emergency.
As Merseyrail have recently rebuilt the tunnel for the new Class 777 trains, I suspect that Stadler can design a Class 755 train, that would be able to avoid the change of train at Bidston.
I’ll Wait For More Information
It would seem prudent to wait for more information.
