HS2 Slab Track Contract Awarded

The title of this post, is the same as that of this article on Rail Business UK.

This is the opening paragraph.

Project promoter High Speed 2 Ltd has awarded a consortium of Porr UK and Aggregate Industries UK the contract to design and manufacture modular slab track for HS2.

The article also says that with the exception of tunnels and some specialist track, all track will be slab track.

What is slab track and why is it used?

These pictures show slab track on the Gospel Oak to Barking Line.

This is obviously not due to high speed, but because space is tight.

This page on the British Continuous Paving Association web site, is entitled Why Build Slab Track?

This is the two opening paragraphs.

Slab track, also called ballastless track, is a modern form of track construction which has been used successfully throughout the world for high speed lines, heavy rail, light rail and tram systems.

Slab track technology offers proven higher performance in service and a longer life than traditional ballasted track.

The article also lists these benefits.

  • Very low maintenance requirements
  • Shallow construction depth
  • Reduced dead load
  • Reduced structure gauge
  • Higher speed operation
  • Engineered noise and vibration performance
  • Long design life
  • Increased reliability
  • Increased availability
  • Low whole-life cost
  • A sustainable solution

Increasingly, slab track is being used for high speed railways, so I am not surprised it will be used on much of High Speed Two.

Darlington Station – 28th October 2020

I went to Teesside to have a look round yesterday.

These are my thoughts on Darlington station.

Platform 1 And Platform 4

These pictures show the two main platforms at Darlington station.

Note.

  1. They are affectively a very wide island platform.
  2. Platform 1 handles all trains going South and East to Middlesbrough and Saltburn.
  3. Platform 4 handles all trains going North and West to Bishop Auckland.
  4. The platforms are well over 200 metres long.
  5. Both the main platforms have a second track, between the current track and the walls of the station.
  6. Both main platforms have a large clock.
  7. Platform 1 has some innovative seating.
  8. Uniquely, there is a London Rail Map on the London-bound Platform 1. Every London-bound platform needs a copy of this map, but they are very rare.

They appear to handle all the current services easily.

There is certainly a lot of space to improve the station.

Station Structure

The station stricture is probably best described as grand, stylish and Victorian and it appears to be in good condition.

  • The tracks through the station are enclosed in two large brick walls.
  • A roof of the period, is supported on the walls and a number of perhaps forty cash-iron columns.

These pictures give a flavour of the station.

There must be few better station structures than Darlington in the UK and as it is Listed Grade II*. I would expect this is recognised by English Heritage.

The Southern Bay Platforms

There are two bay platforms at the Southern end of the station.

There were bay platforms at the Northern end, but these have now been removed.

I wonder, if these two bay platforms could be invaluable in the expansion of services both on the Tees Valley Line and generally in the area.

Current plans envisage the following.

  • Four trains per hour (tph) between Saltburn and Darlington.
  • Two tph between Darlington and Bishop Auckland.

One obvious way to achieve this objective would be to do the following.

  • Run two tph between Saltburn and Bishop Auckland. These trains would run as now with Saltburn services using Platform 1 and Bishop Auckland services using Platform 4 at Darlington station.
  • Run two tph between Saltburn and Darlington. These trains would use Platform 2 at Darlington station.

The advantages of this are.

  • To get to Middlesbrough or Saltburn, you would go to the island Platform 1/2, as you do now.
  • To get to Bishop Auckland, you would go to Platform 4, as you do now.
  • If battery trains were to be used the bay platforms would be ideal for a Vivarail Fast Charge system

There would probably need to be some changes to the tracks serving Platform 1 and 2.

Other possibilities might include.

  • Darlington might also be a useful terminal for a service to Whitby via Middlesbrough.
  • Using the station as a Northern terminus for an Express Parcels Service from London.

Lengthened platforms able to take a five-car Class 802 train, could be useful for service recovery.

The Western Pedestrian Entrance To The Station

Darlington Town Centre lies to the West of the station and these pictures show what probably was a very grand entrance to the station connected to it by a subway.

This Google Map shows the size of the entrance.

It is one of those buildings that would be described by a certain breed of estate agent, as having development potential.

  • There are no lifts to the subway.
  • It could be turned into a retail experience.
  • Does the clock tell the right time?
  • Buses were signposted in this direction, but there appeared to be little information.

Surely, it could be turned into an asset to both the railway and the town.

The Southern Approaches To The Station

These pictures show the Southern approach to the station.

The Tees Valley Line to and from Middlesbrough and Saltburn joins to the South of the station and trains going to Bishop Auckland have to cross over the two tracks of the East Coast Main Line.

This Google Map shows the track layout just to the South of the station.

Note.

  1. The Southern ends of the platforms can just be seen at the top of the map.
  2. Platforms are numbered 1 to 4 from West to East.
  3. The two avoiding lines going past the East side of the station.
  4. The yellow train is one of Network Rail’s Mobile Maintenance Trains.

The Mobile Maintenance Train was parked in the same place yesterday, as this picture shows.

The second Google Map shows Darlington South Junction, where the Tees Valley Line from Middlesbrough joins the East Coast Main Line.

These two maps indicate the problem of train operation at Darlington.

A train between Bishop Auckland in the West and Middlesbrough and Saltburn in the East, can sneak down the Southbound East Coast Main Line and take the Tees Valley Line to continue on its way.

But a train going the other way, needs to cross both tracks of the East Coast Main Line on the flat, which means precision working by drivers and signallers, to avoid causing delays to both main line and local trains.

I suspect all the following are true.

  • The number of London and Scotland expresses will increase.
  • London and Scotland expresses will be running faster.
  • The number of freight services on the route will increase.
  • The number of services between Bishop Auckland and Saltburn will increase from the current hourly only service.
  • High Speed Two will eventually start to run services between London and Birmingham, and at least as far North as Newcastle

All will make the need for improvements South, and probably North, of Darlington station increasingly important.

Could it be that the simplest solution would be to create a dive-under?

  • It would only need to be single-track.
  • It could probably be built without affecting current services, as was the Acton dive-under.
  • There would appear to be plenty of space.

It would only need to allow trains from the Eastern branch of the Tees Valley Line to access Platform 4 at Darlington station.

High Speed Two Is Coming

High Speed Two is coming to Darlington and I wrote about that in £100m Station Revamp Could Double Local Train Services.

This was my conclusion about what will happen to services at Darlington in that post.

I think that this will happen.

  • The Tees Valley Line trains will be greatly improved by this project.
  • Trains will generally run at up to 140 mph on the East Coast Main Line, under full digital control, like a slower High Speed Two.
  • There will be two high speed platforms to the East of the current station, where most if not all of the High Speed Two, LNER and other fast services will stop.
  • There could be up to 15 tph on the high speed lines.

With full step-free access between the high speed and the local platforms in the current station, this will be a great improvement.

So what will the step-free access be like?

The young assistant in WH Smith told me that a hole will be made in the wall on the East side of the current Platform 1.

It does seem that a new bridge could reach over all the platforms with an entrance for the Town Centre in a refurbished Western entrance.

Passengers would arrive by high speed train every few minutes from the South, Newcastle or Scotland.

  • Those for the Town Centre would walk across the bridge and exit the station in a refurbished Western entrance.
  • Those needing onward local train travel would descend into the current station to catch another frequent train.
  • Hopefully, there would be space somewhere for a bus station.

It would be a real gateway station for Darlington.

UK Records A 16% Increase In New Tech Startups

The title of this post, is the same as that of this article on ITPro.

It’s not all bad news out there.

As someone, who started a business in the recession of 1977, and was very successful, now is probably a good time to start the right business.

Scotland seems to have had the largest increase.

Tunnelling Complete At Bank Tube Station

The title of this post, is the same as that of this article on Infrastructure Intelligence.

This is the opening paragraph.

Tunnelling work at the project to modernise and expand Bank Underground station in London has been completed, marking a major milestone in the project. The tunnelling, which forms part of the programme to expand the size of the station by 40%, has seen more than 1.3km of tunnels constructed since May 2017.

I use Bank station regularly and it has been fully-functional during the tunnelling.

Hopefully, it will only in 2022.

Le Pain Quotidien Has Reopened

This is good for coeliacs, as they do reasonable gluten-free food.

I can also get a 73 bus directly to Goodge Street station, where there is a particularly good Le Pain Quotidien, close to a Marks & Spencer food store and a Rymans.

What more could I want?

Note.

  1. I caught the bus close to my house and sat in the tail-gunner’s seat.
  2. The 73 bus has now been rerouted down Tottenham Court Road.
  3. The green-glazed building is University College Hospital. I now have a direct bus to the hospital, where I sometimes go for appointments.
  4. Tottenham Court Road is now two-way for buses, cyclists and taxis.

I shall use that Le Pain Quotidien more often.

So, What Exactly Is Long-Duration Energy Storage?

The title of this post is the same as that of this article on Greentech Media.

This is the sub-title.

Everyone’s talking about it, and Californians are buying in. Here’s what you need to know about this emerging grid sector.

It describes what California is doing and the sector, with particular reference to Hydrostor, Form Energy and Highview Power.

The article finishes with a section entitled What’s The Catch?

This is the first two paragraphs.

The obvious barrier to a thriving long-duration storage industry is convincing generally conservative power plant customers that emerging technologies quite unlike anything the grid currently uses are safe bets for decades of operation.

Lab tests can reduce the risk, but nothing beats operational, megawatt-scale installations for proving that something works. That’s why the Form deal with Great River Energy is so crucial, as are early projects by Highview Power and Hydrostor. The big exception to technology risk is pumped hydro, which has been used at scale for decades. Those projects grapple instead with high capital expense and environmental concerns.

The article is a must-read and hopefully, this and more articles like it, will convince conservative energy company owners, regulators and governments, that long duration energy storage is the missing link between renewable power and electricity consumers.

At least, the current UK Government has backed two of the most promising British long duration energy storage companies; Gravitricity and Highview Power.

TfL Reveals Project Cost Spikes And Delays

The title of this post, is the same as that of this article on Construction News.

This is the introductory paragraph.

Transport for London (TfL) has revealed how the coronavirus pandemic has increased costs and delayed the completion of some of its biggest projects.

Points from the article include.

  • TfL still aim to complete the Northern Line Extension by Autumn 2021, but there has been a 64-day delay caused by the covids.
  • The cost of the Bank station upgrade has risen by £88 million after a nine-week covids delay.
  • The Barking Riverside Extension of the Overground is in serious trouble.

On top of that there are all the problems with Crossrail.

Frankfurt Starts Building Fuel Station For World’s Biggest Zero-Emissions Train Fleet

The title of this post, is the same as that of this article on Reuters.

These are the two opening paragraphs.

German regional transport group RMV began construction on Monday of a filling station near Frankfurt that will use hydrogen generated as a by-product of chemicals manufacturing to fuel the world’s largest fleet of zero-emissions passenger trains.

France’s Alstom will deliver 27 hydrogen-powered fuel cell trains to the Infraserv Hoechst industrial park in the Rhine-Main region in mid-2022. Starting regular local services by that winter, the fleet will replace diesel engines.

All the investment will be partly funded by fares.

Chlorine Manufacture

I find it interesting, that the article also states that the hydrogen comes as a by-product of chlorine manufacture. When I worked in a ICI’s electrolysis plant around 1970, their plant used the Castner-Kellner process to produce both gases.

The process uses a lot of mercury and Wikipedia says this about the future of the process.

The mercury cell process continues in use to this day. Current-day mercury cell plant operations are criticized for environmental release of mercury  leading in some cases to severe mercury poisoning as occurred in Japan Minamata_disease. Due to these concerns, mercury cell plants are being phased out, and a sustained effort is being made to reduce mercury emissions from existing plants.

Are INEOS, who now own the Runcorn plant, and the Germans still using the Castner-Kellner process?

I remember two stories about the theft of mercury from the Runcorn plant.

Mercury was and probably still is very valuable,  and it was always being stolen. So ICI put a radioactive trace in the mercury, which didn’t affect the process. The result was that all legitimate metal dealers on Merseyside bough Geiger counters to check any mercury before they bought it.

One guy thought he had found the ideal way to steal mercury, so he filled his bike frame with the metal and wheeled it to the gate. Whilst he clocked out, he propped the bike against the gate-house. Unfortunately, it fell over and because of the weight of the mercury, he was unable to pick it up.

My work in the plant, involved devising a portable instrument that would detect mercury in air and a colleague’s project was to develop a way of detecting mercury in urine samples from the plant operatives.

Those projects say a lot, about why we should be careful around any process involving mercury.
