Universal Hydrogen And Railway Locomotives
On the product page of the Universal Hydrogen web site, there is a section, which is entitled Other Transportation Applications, where this is said.
Our lightweight, aviation-grade modular hydrogen capsules can be used in a wide range of transportation applications where weight, safety, and speed of refueling are important. We are working with partners in automotive, heavy equipment, maritime, and railroad domains. If you have an application that can benefit from our global modular green hydrogen distribution network, please get in touch!
I believe that the railway locomotive of the future will be hydrogen-electric. And so do some of the UK’s rail freight companies, judging, by some of their press releases.
- It would have an electric transmission. like most locomotives today, such as the UK’s Class 66, Class 68, Class 70, Class 88, Class 93 and the upcoming Class 99 locomotives.
- It will be able to use 25 KVAC overhead electrification, where it exists.
- Hydrogen-power will be used, where there is no electrification.
The lowest-carbon of the locomotives, that I listed, will probably be the Class 99 locomotive.
- Thirty have been ordered by GB Railfreight, from Swiss company; Stadler.
- The locomotives will be built at Valencia in Spain.
- It will have up to 6 MW, when running using electrification.
- It will have up to 1.6 MW, when running using a Cummins diesel, with a rating of 2,150 hp.
- Because a proportion of UK freight routes are electrified, it is likely that these locomotives will substantially reduce carbon emissions for many locomotive-hauled operations.
It should be noted that Cummins are heavily into hydrogen and their philosophy seems to embrace families of engines, which are identical below the cylinder head gasket, but with appropriate cylinder heads and fuel systems, they can run on diesel, natural gas or hydrogen.
I wouldn’t be surprised to find out that the Class 99 locomotive will have a diesel engine, that has a hydrogen-powered sibling under development at Cummins.
With perhaps a power on hydrogen of about 2.5 MW, these zero-carbon locomotives would be able to handle upwards of ninety percent of all heavy freight trains in the UK.
These are further thoughts.
Alternatives To Cummins Hydrogen Internal Combustion Engines
There are two main alternatives, in addition to similar engines from companies like Caterpillar, JCB, Rolls-Royce mtu and others.
- Fuel cells
- Gas-turbine engines.
Note.
- Universal Hydrogen and others have fuel cells, that can probably deliver 2.5 MW.
- Universal Hydrogen use Plug Power fuel cells.
- Rolls-Royce have developed a 2.5 MW electrical generator, based on the engine in a Super Hercules, that is about the size of a typical beer-keg. I wrote about this generator in What Does 2.5 MW Look Like?.
Cummins may be in the pole position with Stadler, but there are interesting ideas out there!
Cummins have also indicated, they will build hydrogen internal combustion engines at Darlington in the UK.
Would One Of Universal Hydrogen’s Hydrogen Capsules Fit In A Railway Locomotive?
These are various widths.
- Class 66 locomotive – 2.63 metres.
- ATR72 airliner – 2.57 metres.
- DHC Dash-8 airliner – 2.52 metres
- Class 43 power car – 2.74 metres
I suspect that even if it was a bit smaller a hydrogen capsule could be made for a UK locomotive.
How Big Is The Market?
The UK has around five hundred diesel railway locomotives.
Low Carbon Construction Of Sizewell C Nuclear Power Station
Sizewell C Nuclear Power Station is going to be built on the Suffolk Coast.
Wikipedia says this about the power station’s construction.
The project is expected to commence before 2024, with construction taking between nine and twelve years, depending on developments at the Hinkley Point C nuclear power station, which is also being developed by EDF Energy and which shares major similarities with the Sizewell plant.
It is a massive project and I believe the construction program will be designed to be as low-carbon as possible.
High Speed Two is following the low-carbon route and as an example, this news item on their web site, which is entitled HS2 Completes Largest Ever UK Pour Of Carbon-Reducing Concrete On Euston Station Site, makes all the right noises.
These three paragraphs explain in detail what has been done on the Euston station site.
The team constructing HS2’s new Euston station has undertaken the largest ever UK pour of Earth Friendly Concrete (EFC) – a material that reduces the amount of carbon embedded into the concrete, saving over 76 tonnes of CO2 overall. John F Hunt, working for HS2’s station Construction Partner, Mace Dragados joint venture, completed the 232 m3 concrete pour in early September.
The EFC product, supplied by Capital Concrete, has been used as a foundation slab that will support polymer silos used for future piling works at the north of the Euston station site. Whilst the foundation is temporary, it will be in use for two years, and historically would have been constructed with a more traditional cement-based concrete.
The use of the product on this scale is an important step forward in how new, innovative environmentally sustainable products can be used in construction. It also helps support HS2’s objective of net-zero construction by 2035, and achieve its goal of halving the amount of carbon in the construction of Britain’s new high speed rail line.
Note.
- Ten of these slabs would fill an Olympic swimming pool.
- I first wrote about Earth Friendly Concrete (EFC) in this post called Earth Friendly Concrete.
- EFC is an Australian invention and is based on a geopolymer binder that is made from the chemical activation of two recycled industrial wastes; flyash and slag.
- HS2’s objective of net-zero construction by 2035 is laudable.
- It does appear that this is a trial, but as the slab will be removed in two years, they will be able to examine in detail how it performed.
I hope the Sizewell C project team are following High Speed Two’s lead.
Rail Support For Sizewell C
The Sizewell site has a rail connection and it appears that this will be used to bring in construction materials for the project.
In the January 2023 Edition of Modern Railways, there is an article, which is entitled Rail Set To Support Sizewell C Construction.
It details how sidings will be built to support the construction, with up to four trains per day (tpd), but electrification is not mentioned.
This is surprising to me, as increasingly, big construction projects are being managed to emit as small an amount of carbon as possible. Sizewell C may be an isolated site, but in Sizewell B, it’s got one of the UK’s biggest independent carbon-free electricity generators a couple of hundred metres away.
The writer of the Modern Railways article, thinks an opportunity is being missed.
I feel the following should be done.
- Improve and electrify the East Suffolk Line between Ipswich and Saxmundham Junction.
- Electrify the Aldeburgh Branch Line and the sidings to support the construction or agree to use battery-electric or hydrogen zero-carbon locomotives.
Sizewell C could be a superb demonstration project for low-carbon construction!
Sizewell C Deliveries
Sizewell C will be a massive project and and will require a large number of deliveries, many of which will be heavy.
The roads in the area are congested, so I suspect rail is the preferred method for deliveries.
We already know from the Modern Railways article, that four tpd will shuttle material to a number of sidings close to the site. This is a good start.
Since Sizewell A opened, trains have regularly served the Sizewell site to bring in and take out nuclear material. These occasional trains go via Ipswich and in the last couple of years have generally been hauled by Class 88 electro-diesel locomotives.
It would be reasonable to assume that the Sizewell C sidings will be served in the same manner.
But the route between Westerfield Junction and Ipswich station is becoming increasingly busy with the following services.
- Greater Anglia’s London and Norwich services
- Greater Anglia’s Ipswich and Cambridge services
- Greater Anglia’s Ipswich and Felixstowe services
- Greater Anglia’s Ipswich and Lowestoft services
- Greater Anglia’s Ipswich and Peterborough services
- Freight services serving the Port of Felixstowe, which are expected to increase significantly in forthcoming years.
But the Modern Railways article says this about Saxmundham junction.
Saxmundham junction, where the branch meets the main line, will be relaid on a slightly revised alignment, retaining the existing layout but with full signalling giving three routes from the junction protecting signal on the Down East Suffolk line and two in the Down direction on the bidirectional Up East Suffolk line. Trap points will be installed on the branch to protect the main line, with the exit signal having routes to both running lines.
Does the comprehensive signalling mean that a freight train can enter or leave the Sizewell sidings to or from either the busy Ipswich or the quieter Lowestoft direction in a very safe manner?
I’m no expert on signalling, but I think it does.
- A train coming from the Lowestoft direction needing to enter the sidings would go past Saxmundham junction on the Up line. Once clear of the junction, it would stop and reverse into the branch.
- A train coming from the Ipswich direction needing to enter the sidings would approach in the wrong direction on the Up line and go straight into the branch.
- A train leaving the sidings in the Lowestoft direction would exit from the branch and take the Up line until it became single track. The train would then stop and reverse on to the Down line and take this all the way to Lowestoft.
- A train leaving the sidings in the Ipswich direction would exit from the branch and take the Up line all the way to Ipswich.
There would need to be ability to move the locomotive from one end to the other inside the Sizewell site or perhaps these trains could be run with a locomotive on both ends.
The advantage of being able to run freight trains between Sizewell and Lowestoft becomes obvious, when you look at this Google Map, which shows the Port of Lowestoft.
Note.
- The Inner Harbour of the Port of Lowestoft.
- The East Suffolk Line running East-West to the North of the Inner Harbour.
- Lowestoft station at the East side of the map.
I doubt it would be the most difficult or expensive of projects to build a small freight terminal on the North side of the Inner Harbour.
I suspect that the easiest way to bring the material needed to build the power station to Sizewell would be to do the following.
- Deliver it to the Port of Lowestoft by ship.
- Tranship to a suitable shuttle train for the journey to the Sizewell sidings.
- I estimate that the distance is only about 25 miles and a battery or hydrogen locomotive will surely be available in the UK in the next few years, that will be able to provide the motive power for the return journey.
In The TruckTrain, I wrote about a revolutionary freight concept, that could be ideal for the Sizewell freight shuttle.
In addition, there is no reason, why shuttle trains couldn’t come in from anywhere connected to the East Suffolk Line.
Zero-Carbon Construction
Sizewell C could be the first major construction site in the UK to use electricity rather than diesel simply because of its neighbour.
Conclusion
I shall be following the construction methods at Sizewell C, as I’m fairly sure they will break new ground in the decarbonisation of the Construction industry.
Class 99 Electro-Diesel Locomotive Order Confirmed
The title of this post, is the same as that of this article on Railway Gazette.
This first paragraph gives details of the order.
GB Railfreight, leasing company Beacon Rail and Stadler have signed an agreement for the supply of 30 Class 99 six-axle electro-diesel locomotives for entry into service from 2025. The operator said they would the first electro-diesel locomotives capable of hauling heavy freight at main line speeds on the UK network.
The article also gives these technical details of the Class 99 locomotives.
- Ability to operate under 25 KVAC overhead electrification.
- Up to 6,000 kW under electrification.
- Maximum speed of 120 km/h (75 mph)
- ‘high-power low-emissions’ Stage V diesel engine.
- Tractive effort of up to 500 kN
- The locomotives will be compatible with British the UK loading gauge and specifications.
This document on the Stadler web site is the specification for the Stadler Euro Dual locomotives, that have been sold to German operator; HVLE.
These are some technical details.
- Ability to operate under 25 KVAC overhead electrification or 15 KVAC German overhead electrification.
- Up to 6,000 kW under electrification.
- Maximum speed of 120 km/h
- Caterpillar C175-16 Stage IIIB diesel engine.
- Engine output of 2,800 kW
- Tractive effort of up to 500 kN
- A Euro Dual locomotive has a length of 23 metres
- A Euro Dual locomotive has a 3,500 litre fuel tank.
Wikipedia gives details of a Stadler Class 68 locomotive, which is shown in this picture.
These are some details.
- There are 34 Class 68 locomotives in service in the UK.
- Caterpillar C175-16 Stage IIIB diesel engine.
- Engine output of 2,800 kW
- A Class 68 locomotive has a 5,000 litre fuel tank.
- A Class 68 locomotive has a length of 20.5 metres.
- It should be noted, that a Class 66 locomotive has an engine output of 2,500 kW.
These are my thoughts on the design and specification of the Class 99 locomotive.
The Diesel Engine
The Class 68 and the Euro Dual appear to have a diesel engine, with these specifications.
- Caterpillar C175-16 Stage IIIB diesel engine.
- Engine output of 2,800 kW
Whereas the Class 99 locomotive is stated as having a ‘high-power low-emissions’ Stage V diesel engine.
So have Stadler fitted the latest Caterpillar C175-16 Stage V diesel engine into a Class 99 locomotive?
This would surely be likely, as any reputable diesel engine company would strive to reduce the emissions of their engines and make them compatible with the latest regulations.
Will 2,800 kW Be Enough Power On Diesel?
If the Class 99 locomotive has 2,800 kW from the latest Caterpillar diesel engine, this is the same as for a Class 68 and the Euro Dual, so it is likely to be enough power.
It is also more power, than is available from a Class 66 locomotive.
What Will Be The Length Of The Class 99 Locomotive?
It does appear that the Class 68 locomotive is 20.5 metres long and the Euro Dual is 23 metres long.
But this is not really unexpected as the Euro Dual has two larger three-axle bogies.
I suspect to use the equipment layout of the Euro Dual, that the Class 99 locomotive could be 23 metres long.
What About The UK Loading Gauge?
When it came to designing the Class 68, 88 and 93 locomotives, Stadler had no difficulty fitting all the gubbins in a 20.5 metre package.
If I am right in surmising that a Class 99 locomotive will be longer because of its larger bogies, I suspect that modern computer-aided design will enable Stadler to create a locomotive, that will fit the UK loading gauge.
Conclusion
It does appear that a design based around the latest version of a Caterpillar C175-16 will be possible.
A Cool Move To Keep Emissions On Track
The title of this post is the same as that of this press release from Tesco.
This is the body of the release.
- Tesco and DRS partner on a new refrigerated rail freight service that will take 40 lorries off the road for every journey it makes
- Helping Tesco to deliver Christmas, the service will run seven days a week and replace 7.3 million road miles with greener distribution
- New service supports Tesco’s commitment to reach net zero emissions in its operations by 2035
Tesco and Direct Rail Services (DRS) have partnered to introduce a cool new service to Britain’s railways.
The new service will be the first time Tesco has used refrigerated rail freight in the UK, distributing chilled goods from Tilbury to Coatbridge by low CO2 rail twice a day, seven days a week. This means that rail freight will play an even bigger role in helping Tesco to deliver Christmas this year and over the next couple of weeks this new service will transport hundreds of different products, including festive favourites such as sprouts, parsnips, carrots, onions, oranges and lemons just in time for that all important Christmas dinner.
Using rail has significant environmental benefits. The 415-mile route will use DRS’s Class 88 bi-mode electric locomotives which can run on electricity and produce zero exhaust and greenhouse gas emissions. This service alone will take at least 17,000 containers off the road each year, saving Tesco 7.3 million road miles and nearly 9,000 tonnes of CO2e.
Note.
- This is Tesco’s first use of refrigerated rail freight.
- It starts from the new Tilbury 2 freight terminal.
- All services seem to be run using bi-mode Class 88 locomotives, running for most of the route using electricity.
Tesco seem to be following the rule, that every little helps when it comes to decarbonisation and climate change.
This Google Map shows Tilbury.
Note.
- The Port of Tilbury is in the West.
- Tilbury Town station on the Tilbury Loop Line is on the North side of the Port.
- There is a cruise ship at the London Cruise Terminal on the river.
- Next to the terminal is the Gravesend Tilbury Ferry. I can remember the car ferries on this route.
- Then there is Tilbury Fort.
- The Tilbury 2 Terminal is in the East.
I took these pictures in 2017.
I suspect it’s a bit different now!
The Future Of The Class 68 Locomotives
This post has been brought on by the comments to two posts I have written today.
- Direct Rail Services Disposes Of Heritage Locomotives
- Suppliers Sought For New Bi-Mode Locomotives For TransPennine Express And Great Western Railway
Both Direct Rail Services and TransPennine Express are major users of Class 68 locomotives, with each having a fleet of fourteen locomotives.
In addition, Chiltern Railways has a smaller fleet of six locomotives.
- Direct Rail Services use their locomotives for various passenger and freight duties, including the important one of moving nuclear material around the country.
- TransPennine Express use their locomotives on their passenger services across the North of England.
- Chiltern Railways use their locomotives on their passenger services between London and Birmingham and sometimes Oxford.
The design was a bespoke one by Stadler for Direct Rail Services and the first one entered service in 2014.
The picture shows one of TransPennine’s Class 68 locomotives at Scarborough. As the picture shows, they are a smart and purposeful-looking locomotive, that wouldn’t look out of place in the right livery on the front of the Royal Train.
It has some good features.
- It is a 100 mph locomotive.
- It seems to be well-liked by operators.
- It can haul both passenger and freight trains.
- It can act as a Thunderbird or rescue locomotive.
But they have three problems; emissions, noise and diesel.
This is from Wikipedia.
The locomotive’s propulsion system is compliant with Stage III A of the European emission standards, but not the more stringent Stage III B requirements.
But noise is a another problem and this has caused council action in Scarborough.
More important than emissions or noise, is the fact, that the locomotive is diesel-powered, so the fleet will probably have to be retired from the railway, at a time, when there is still useful life left in the locomotives.
The Class 68 locomotive is a member of the Stadler Eurolight family, of which there are three versions.
All follow similar design principles, differing mainly in dimensions, with Spain, Taiwan and the UK ordering upwards of twenty-thirty locomotives.
The UKLight branch of the family has two other members.
The Class 88 locomotive is an electro-diesel version of the Class 68 locomotive and the development of the design is described in this extract from the Class 88 locomotive’s Wikipedia entry.
Amid the fulfillment of DRS’ order for the Class 68, Stadler’s team proposed the development of a dual-mode locomotive that could be alternatively powered by an onboard diesel engine or via electricity supplied from overhead lines (OHLE). Having been impressed by the concept, DRS opted to place an order for ten Class 88s during September 2013. Having been developed alongside the Class 68, considerable similarities are shared between the two locomotives, amounting to roughly 70 percent of all components being shared.
According to Wikipedia, the type had a smooth entry into service.
The Class 93 locomotive will be the next development of the UKLight branch of the family, when it is delivered in 2023.
It will be a tri-mode locomotive, that will be capable of being powered by 25 KVAC overhead electrification, an onboard diesel engine and batteries.
It will be a 110 mph locomotive.
It can haul both passenger and freight trains.
Rail Operations Group have ordered 30 locomotives.
This is the first paragraph of the section in Wikipedia called Specification.
The Class 93 locomotive has been developed to satisfy a requirement for a fast freight locomotive that uses electric power while under the wires, but is also capable of self-powered operations. Accordingly, it is capable of running on diesel engines, from overhead wires, or from its onboard batteries. These batteries, which occupy the space used for the braking resistors in the Class 88, are charged via the onboard transformer or regenerative braking; when the batteries are fully charged, the locomotive only has its friction brakes available. The diesel engine is a six-cylinder Caterpillar C32 turbocharged power unit, rated at 900 kW, conforming with the EU97/68 stage V emission standard. The batteries units are made of Lithium Titanate Oxide and use a liquid cooling solution, enabling rapid charge and discharge.
It is a truly agnostic locomotive, that can take its power from anywhere.
The last paragraph of the specification compares the locomotive to the Class 66 locomotive.
In comparison with the Class 66, the Class 93 can outperform it in various metrics. In addition to a higher top speed, the locomotive possesses greater acceleration and far lower operating costs, consuming only a third of the fuel of a Class 66 along with lower track access charges due to its lower weight. ROG has postulated that it presents a superior business case, particularly for intermodal rail freight operations, while also being better suited for mixed-traffic operations as well. Each locomotive has a reported rough cost of £4 million.
It is no ordinary locomotive and it will change rail freight operations in the UK.
I have a feeling that the Class 93 locomotive could be a lower-carbon replacement for the Class 68 locomotive.
But I also believe that what Stadler have learned in the development of the Class 93 locomotive can be applied to the Class 68 locomotive to convert them into zero-carbon locomotives.
It may be just a matter of throwing out the diesel engine and the related gubbins and replacing them with a large battery. This process seems to have worked with Wabtec’s conversion of diesel locomotives to FLXdrive battery-electric locomotives.
Direct Rail Services Disposes Of Heritage Locomotives
The title of this post, is the same as that of this article on Rail Magazine.
This is the first paragraph.
Direct Rail Services, the rail arm of Nuclear Transport Solutions (NTS), has announced details of its much-anticipated plan to sell off some of its heritage fleet of locomotives and coaching stock.
The main job of Direct Rail Services is to move nuclear fuel and other cargoes around the country in support of the UK’s nuclear industry. For this purpose, they have a substantial fleet of over fifty modern Class 66, Class 68 and Class 88 locomotives, which seem to have taken over from the heritage fleet, which are now starting to be passed on to other operators.
Direct Rail Services also tend to be the odd-job men and innovators of the traction business.
- They have provided modern motive power for both regular, charter and replacement passenger services.
- They haul freight trains for supermarkets and others.
- They sub-lease Class 68 locomotives to other operators.
- Both the Class 68 and Class 88 locomotives are 100 mph-capable, which must widen their markets.
- They have supplied locomotives for Thunderbird duties.
- They are happy to specify a new locomotive and bring it into service, as they did with the Class 68 and Class 88.
According to Wikipedia, they have issued a tender for a further ten new-build diesel-electric locomotives.
Will these be an existing design or another new design?
This is a section of the Wikipedia entry for the Class 88 locomotive.
Akin to the Class 68, the Class 88 can achieve a maximum speed of 100 mph (160 km/h), sufficient for regular passenger operations, while operating under OHLE, it has a power output of 4,000 kW (5,400 hp). Under diesel power, provided by its 12-cylinder Caterpillar C27, it has a maximum power output of 708 kW (949 hp); however, the maximum tractive effort is available in either mode. The locomotive’s engine, which is compliant with the current EU Stage IIIB emission restrictions, has limited available power as a result of the customer’s choice to give the Class 88 comparable power to a traditional Class 20.
It almost looks like a design for all purposes.
- It can pull a passenger train at 100 mph.
- With the right rolling stock, it must be able to pull a freight train at 100 mph.
- A 100 mph freight capability must be very useful on double-track electrified main lines like the East and West Coast Main Lines, where it would increase capacity.
- It probably has enough power to drag a freight train out of the depot on to an electrified main line.
- The locomotive would appear to be able to do anything that one of Direct Rail Services’s Class 20 locomotives can do, which would surely enable it to pick-up a nuclear flask from a remote power station.
- But it would also be able to transport the flask back to Cumbria using electric power, where it is available.
- In ’88’ Makes Sizewell Debut, I describe how a Class 88 locomotive moved a flask from Sizewell to Crewe.
- It is compliant with the latest emission regulations.
- It can use regenerative braking, where the electrification can handle it.
I wonder, if Direct Rail Services are going to add a locomotive to their fleet, that is capable of bringing the longest and heaviest freight trains out of the Port of Felixstowe.
- The Felixstowe Branch is a fairly flat track.
- The only moderately severe gradients ae either side of the Spring Road Viaduct.
- Some electrification could be added.
- A 100 mph freight capability would help in increasing the capacity of the Great Eastern Main Line to and from London.
The right locomotive might be able to haul smaller freight trains between Felixstowe and Peterborough.
Conclusion
There has been no news about the extra ten locomotives that Direct Rail Services will order.
The company has form in designing the right locomotive for the job they will do.
I think, that when the order is placed, it could add another type of locomotive to Direct Rail Services’s fleet.
Watford Junction Station’s Barrier Seats
I quite like these seats at Watford Junction station.
They would appear to give a nice perch to sit, whilst waiting for the train and also act as a crush barrier for the glass shelter behind.
They also give me something to hold, when a train goes through.
The train shown in the picture was a Tesco train between Tilbury and Daventry.
It went through the station at probably over 60 mph.
It had the usual smelly and polluting Class 66 on the front.
It took four hours 45 minutes for the journey, which included the Gospel Oak and Barking Line through London.
I did note earlier that the train seemed to be using modern wagons.
Are these wagons faster than those you generally see on UK railways?
Surely too, this is the type of train, that could be hauled by an electric locomotive with a Last-Mile capability, like a Class 88 Locomotive.
I would have thought, that Tesco could benefit, by using electric haulage, especially if the locomotive was appropriately liveried.
Nunhead Junction Improvement
London has a rail capacity problem, for both freight and passenger trains.
This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).
One of the secondary recommendations of the report is to improve Nunhead junction.
The report explains it like this.
Rail freight stakeholders have consistently highlighted Nunhead as a priority location for improving the flow of freight around the London orbital routes. The junction to the immediate east of the station is a flat crossing where two lines of route and multiple passenger and freight services groups converge into the South London Line, creating a pinch point for capacity.
Freight train drivers, when consulted for input into this strategy, flagged the route eastbound from Peckham Rye through Nunhead and towards Lewisham as a challenging section on which to keep heavier trains moving. This is primarily a consequence of the relatively slow permissible speed of 25mph over Nunhead Junction when routed towards Lewisham,
which follows a steadily rising gradient from Peckham Rye.The option proposed by this strategy is for changes to the track alignment in order to increase the speed of the turnout towards Lewisham, as far as can be achieved without affecting the speed of the main route towards Catford. This option would primarily benefit the performance of eastbound freight flowing from the South London Line towards the North Kent lines, one of the key rail freight corridors in the South East, enabling freight trains to run at faster and more consistent speeds towards Lewisham.
This would most likely increase right time presentation at the critical flat junction at Lewisham, as well as assisting the flow of passenger and freight trains to the Catford Loop by ensuring preceding Lewisham-bound traffic can clear Nunhead Junction as quickly as possible.
Addressing the existing constraints to freight traffic through Nunhead, which by their nature most affect the heavier bulk traffic that characterises the North Kent corridor, would also support industry aspirations to maximise the payloads that trains can haul.
This map from cartometro.com shows the route between Nunhead and Lewisham stations.
And this Google Map shows Nunhead station and the junction.
Note.
- Nunhead junction is towards the right of the map.
- The lines going to the East go to Lewisham.
- The lines going to the South East go to Crofton Park and Catford.
- I have counted the freight trains through Nunhead junction on real time trains and there can be as main as six trains per hour (tph), through the junction at times, using both Lewisham and Crofton Park routes.
But there would also appear to be plenty of space around the junction to realign the tracks.
As many trains need to go East from Lewisham and there are two flat junctions on the route; Nunhead and Lewisham, anything that improves keeping to schedule is to be welcomed.
The Use Of Electric Haulage
All routes through Nunhead junction have 750 VDC third-rail electrification, but I suspect all freight trains through the junction are diesel hauled.
Real time trains also shows that many of the trains through Nunhead junction also use the West London Line through Shepherd’s Bush.
In Decarbonisation Of London’s Freight Routes, I proposed a dual-voltage battery-electric locomotive to handle freight trains.
Perhaps more capable battery-electric freight locomotives with their better acceleration, are part of the solution at Nunhead junction.
Conclusion
This appears to be a well-thought out solution to one of the problems for freight trains in London.
I also believe that dual-voltage battery-electric locomotives could be part of the solution at Nunhead junction and would also help in many other places on the UK rail network.

Class 88 Locomotive Heads On To The East Coast Main Line
The title of this post, is the same as that of this article on Rail Advent.
This is the first three paragraphs.
Direct Rail Services has confirmed that one of its Class 88 broke new ground last week when it ran the length of the East Coast Main Line.
Last weekend, freight operator, DRS, ran a new diversionary route to enable the Class 88 locomotives to run almost the length of the ECML on electric power, as well as feeder routes that link up Daventry and Mossend.
The route normally follows the West Coast Main Line, but engineering work last weekend required a diversion.
That makes a second Class 88 locomotive story, where the locomotives are serving new routes, after ’88’ Makes Sizewell Debut.
Could it be that with new electrification coming on stream and more being planned, Direct Rail Services are researching what these locomotives can do?
The Route
As the Rail Advent article says, the route is electric all the way from Mossend to Daventry.
Mossend to Edinburgh via the Shotts Line.
- Edinburgh to Stevenage via the East Coast Main Line.
- Stevenage to Alexandra Palace via the Hertford Loop Line.
- Alexandra Palace to Camden Road Central Junction via the East Coast Main Line.
- Xamden Road Central Junction to Camden Junction via the North London Line.
- Camden Junction to Daventry via the West Coast Main Line.
But it does go round the houses!
Note.
- The journey took fifteen hours and it arrived about two-and-a-half hours late.
- Edinburgh to Stevenage was timed to take seven hours, whereas passengers can do that journey in four-and-a half hours with a change.
With some strategic electrification would the train be able to cut across from the East Coast Main Line to reach Daventry?
The Future Of Direct Rail Services
Direct Rail Services have a mixed fleet of locomotives.
- 23 x Class 37 diesel locomotives, which were built in the 1960s.
- 21 x Class 57 diesel locomotives, which were built in the 1960s.
- 19 x Class 66 diesel locomotives
- 34 x Class 68 diesel locomotives
- 10 x Class 88 electro-diesel locomotives
Only the last two types are modern locomotives, that are capable of hauling trains at 100 mph.
The Wikipedia entry also says this.
In September 2017, Direct Rail Services issued a tender for ten brand new diesel-electric locomotives.
Consider.
- As Government policy is a zero-carbon UK by 2050, is that likely to change the tender to electro-diesel locomotives?
- Direct Rail Services is owned by the Government,
- The order from Rail Operations Group for Class 93 locomotives seems to have stalled.
- Rail Operations Group have some ambitious plans for the use of the tri-mode 110 mph Class 93 locomotives, which I wrote about in Rail Operations Group Gets Serious About Thunderbirds Etc.
- As any locomotives delivered in the next few years, will probably still be running in 2060, surely this conflicts with Government policy.
Perhaps, all three parties are working on a cunning plan to jointly order a common design.
