The Diesel Power Of The Class 805 Trains
Avanti West Coast’s new Class 805 trains, will probably start running between London Euston and Chester, Shrewsbury and North Wales before the end of the year.
But will they have the 560 kW engines of the Class 800 trains or the the 700 kW engines of the Class 802 trains?
On this page of Eversholt Rail’s web site, there is a detailed specification for a Class 802 train.
It says these trains have a top speed of 110 mph on diesel.
But it also says this about the design of the trains.
They have been designed to meet the operational requirements of the West of England route and are used on services out of London Paddington to Plymouth and Penzance.
The class 802 is almost identical to the class 800, the differences are that class 802s have a higher rated engine output to tackle the gradients through Devon and Cornwall, and a superior diesel range to provide the IET experience to the wider Greater Western Network, they also have a larger brake resistor which reduces brake pad usage and requires less maintenance.
Wikipedia also says that these are the diesel engine sizes in the three main classes of these Hitachi AT 300 trains.
- Class 800 train – 560 kW – Three engines for five cars
- Class 801 train – 560 kW – One emergency engine for five cars
- Class 802 train – 700 kW – Three engines for five cars
- Class 810 train – 735 kW – Four engines for five cars
All these four trains have similar bodyshells and running gear, so I suspect that to run at similar cruising speeds, similar amounts of power will be needed.
If the Class 802 train has a speed of 110 mph on diesel, then a rough estimate of the cruising speed of a train with the 560 kW engines can be estimated by doing this simple calculation. Note that air resistance is proportional to the square of the speed.
Square root (110*110 *560/700) = 98.4 mph
I have looked on OpenRailwayMap at all the tracks to the West of Wolverhampton, where these trains will run and the highest maximum operating speed I can find is 90 mph.
As the Class 805 trains have a reprofiled nose, which could be more aerodynamic, they may be able to cruise at 90 mph.
I believe that a train with three 560 kW engines will suit Avanti West Coast purposes well.
What Is The Operating Speed Of The Class 810 trains?
I can use a similar calculation to estimate the maximum operating speed of the Class 810 trains, that will operate on the Midland Main Line.
Consider.
- The Class 802 train has a total power of 2100 kW
- The Class 810 train has a total power of 2940 kW
- The Class 810 train with only three working engines has a total power of 2205 kW
I can estimate the cruising speed by doing this simple calculation, which is similar to the one for the Class 805 train.
Square root (110*110 *2940/2100) = 130 mph
I can also do it for a train running on three engines.
Square root (110*110 *2205/2100) = 113 mph
I looks to me, that the following is possible.
- As Class 810 trains can achieve the maximum speed of 125 mph on both diesel and electric power, the timetable is independent of the progress of the electrification.
- If the 125 mph sections are ignored, the fastest sections of line have a maximum speed of 110 mph, which could be possible on three engines.
- North of the electrification, where the maximum speed is only 110 mph, engines could be selectively rested to avoid overheating.
Four engines give a lot of interesting options.
I can’t wait to take a ride.
Could The Class 810 Trains Be Fitted With Batteries?
When, the electrification reaches Market Harborough station, there will be no 125 mph sections on the Midland Main Line, which are not electrified.
This Hitachi infographic shows the Hitachi Intercity Tri-Mode Battery Train.
A Class 810 version of this train would have three diesel engines and one battery pack.
- It would have all the features of the infographic.
- My calculations give it a top speed of 113 mph on a route, where the maximum speed North of the electrification is 110 mph.
- I also suspect, it could bridge any small gaps in the electrification.
It would have the very positive effects of saving fuel and cutting pollution in stations.
New Rolls-Royce Engine For Hybrid-Electric Flight Completes Successful First Fuel Burn
The title of this post is the same as that of this press release from Rolls-Royce.
This is the sub-heading.
A new Rolls-Royce small gas turbine that has been specifically developed to power hybrid-electric flight has successfully completed its first fuel burn. The engine has been designed using novel combustion technology to produce ultra-low emissions and this significant achievement confirms the effectiveness of the compact, power-dense turbine that will be integrated into a light-weight turbogenerator system.
This first paragraph gives more details.
The complete turbogenerator system is being developed for the Advanced Air Mobility (AAM) market. This includes electrical vertical take-off and landing (eVTOL) or electric short take-off and landing (eSTOL) aircraft for Urban Air Mobility (UAM) and commuter aircraft applications up to 19 seats. The gas turbine under test also has potential applications within helicopter, auxiliary power unit (APU) and defense markets.
Looking at Wikipedia, it appears that a typical 19 seat airliner needs two engines with a power between 500 and 600 kW.
This would fit with the next paragraph of the press release.
The turbogenerator system will complement Rolls-Royce’s electrical propulsion portfolio by delivering an on-board power source with scalable power offerings between 500 kW and 1,200 kW enabling extended range on sustainable aviation fuels and later, as it becomes available, through hydrogen combustion. This will open up new, longer routes than electric battery powered aircraft can support today.
I can envisage electric 19-seat airliners powered by either two 600 kW engines or one 1200 kW engine.
But then the mind boggles at the applications for this range of engines.
Rolls-Royce And Zero Petroleum Join Forces To Develop Sustainable Future
The title of this post, is the same as that of this press release from Rolls Royce.
This is the sub-heading.
Rolls-Royce has entered a landmark agreement with breakthrough Energy company Zero Petroleum to promote further development of the company’s power and propulsion solutions with fossil-free synthetic fuels.
These two paragraphs outline the agreement.
The new agreement will see the two parties collaborate to demonstrate Rolls-Royce engines for aviation, marine and defence with Zero® synthetic fuels.
This has the potential to include Zero’s entire range of synthetic fuels – petrol, diesel and jet fuel – with data gathered from engine testing used to prove the credentials required to achieve international fuel certification standards. Synthetic fuels deployed by Rolls-Royce in engine tests will directly reduce associated carbon emissions.
Are Rolls-Royce going to do their engine testing using synthetic fuels to reduce their carbon emissions?
It certainly looks like they might and I suppose it does two tests at the same time.
Rolls-Royce Seem To Be Using Technology To Save The Company
Big companies like Rolls-Royce, who are very much toed up with fossil fuels have two options; give up or fight using the only weapons they have; superb technology and a lot of experience.
There are only a small group, that seem to be fighting to succeed. To Rolls-Royce, I would add Cummins, Fortescue Future Industries, Ricardo and SSE, and possibly BP and Centrica.
Wrightbus To Provide Hydrogen Buses For Sizewell C Nuclear Plant
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Ballymena bus manufacturer Wrightbus is providing four hydrogen buses to the Sizewell C nuclear power site as part of a pilot scheme.
These first three paragraphs outline the scheme.
If successful, up to 150 buses could be ordered, making it one of the largest hydrogen bus fleets in the world.
Construction of the plant is to begin next year and multiple vehicles will be needed to move workers to and from the site.
Sizewell C will test the performance of four double-decker buses.
As I used to live in that area, I know the buses are bad and this will surely help.
Yorkshire To See More LNER Services And Longer Trains
The title of this post, is the same as that of this article on Rail UK.
These are the two introductory paragraphs.
London North Eastern Railway (LNER) is meeting an increase in demand from leisure travellers by adding more services and thousands more seats on trains between Yorkshire and London every Sunday.
Sundays are now one of the most popular days for journeys with 30% more customers travelling across the 956-mile LNER network than in 2019.
From December 2023, three new services and longer trains will be introduced on Sundays between London and Yorkshire.
Development Around Liverpool Street Elizabeth Line Station
After my Full English breakfast in Leon this morning, I walked around the area between the two entrances to Liverpool Street station on the Elizabeth Line, before entering the station at the Liverpool Street entrance.
I took these pictures as I walked.
Note.
- The large development with the naked concrete towers is the Western extension to Broadgate.
- The old entrance to Moorgate Underground station and two pubs are squeezed in between the modern buildings.
- The cylindrical building behind the Globe pub, is Moor House.
- Some buildings are brand new and others are older ones, that have been refurbished and/or reskinned.
There is hardly any space left to put in a dog kennel.
Silvertown Tunnel Works – 24th September 2023
I took these pictures of the Silvertown Tunnel works on the North Bank of the Thames today.
I was on a train going to Woolwich Arsenal.
What Is The Silvertown Tunnel?
The title of this section, is the same as that of this article on the Londonist, which is an excellent description of the Silvertown Tunnel.
The article says this about tolls.
The new tunnel will require you to part with some pounds if you want to use it. Despite the consultation on this taking place a decade ago, the final details have yet to be publicised. We can expect something similar to the Dartford Crossing (currently £2.50 for cars etc, free for motorbikes/mopeds).
As there is a mayoral election next year, I doubt that Sadiq Khan will announce the charge on the Silvertown and Blackwall Tunnels before the election.
Let’s Play Accountants
This is a paragraph in the Londonist Article.
Construction of the tunnel is eating up something like £1.2 billion (2020 estimate). It’ll then cost another estimated £1 billion over 25 years to pay for maintenance, financing and operation. Riverlinx paid up-front costs and will be paid back by TfL through money collected from tolls.
The running costs would appear to be a billion over 25 years, which is £ 40,000,000 in a year.
This is said on this page on the Greater London Assembly web site.
Blackwall tunnels (northbound and southbound) each carry approximately 50,000 vehicles per day in only two lanes of traffic.
That means that each tunnel handles approximately 18,250,000 vehicles per year.
Dartford Crossing charges are according to the Wikipedia entry are as follows.
- Cars, motorhomes, small minibuses – £ 2.50
- 2-axle buses, coaches, vans, goods – £ 3.00
- Multi-axle goods, coaches – £ 6.00
The Wikipedia entry also says this about the capacity and traffic through and over the Dartford Crossing.
The design capacity is 135,000 vehicles per day, but in practice the crossing carries around 160,000.
My good friend; Bob from the 1970s had an impeccable cv.
- Chief Accountant of Vickers.
- Chief Management Accountant of Lloyds Bank.
He was also one of two outstanding practical accountants I have known.
Several of his practical tips on how to handle money in computers, ended up in Artemis; the project management computer system, I wrote in the 1970.
Bob and I would solve problems in Mother Bunches Wine Bar and I suspect, we’d come to the conclusion, that an average charge of £3 per vehicle will be charged in the Blackwall and Silvertown Tunnels.
I also believe from my fluid flow experience, that a proportion of the excess traffic through and over the Dartford Crossing will divert to the new Silvertown Tunnel.
- Together the Blackwall and Silvertown Tunnels will have four lanes in both directions.
- The Silvertown Tunnel will hopefully designed to modern standards and be more free-flowing, than the Blackwall.
- Sat-navs will direct drivers to the quickest routes.
Just as water finds its own level, an equilibrium will develop between the flows.
- I suspect that during the day, the flow over the Dartford Crossing will drop to the design capacity of 135,000
- At night, will vehicles divert through the free-flowing Blackwall and Silvertown Tunnels?
- Will those living in North Central London inside the North Circular Road drive through the Blackwall and Silvertown Tunnels?
- Will the free-flowing Blackwall and Silvertown Tunnels encourage people crossing the Thames to use their car, rather than the train, as the car is more convenient and the toll will be less than the train fare?
- We should also beware that new roads, railways and tunnels generate new traffic, that no-one predicts.
My feeling is that combined traffic through the four lanes of the Blackwall and Silvertown Tunnels will be upwards of seventy thousand per day.
I can now calculate revenue for different levels of combined traffic through the Blackwall and Silvertown Tunnels.
- 40,000 vehicles in each direction per day is a total of 29,200,000 vehicles per year, which would raise £ 87.6 million per year in toll charges.
- 50,000 vehicles in each direction per day is a total of 36,500,000 vehicles per year, which would raise £ 109.5 million per year in toll charges.
- 60,000 vehicles in each direction per day is a total of 43,800,000 vehicles per year, which would raise £ 131.4 million per year in toll charges.
- 70,000 vehicles in each direction per day is a total of 51,100,000 vehicles per year, which would raise £ 153.3 million per year in toll charges.
- 80,000 vehicles in each direction per day is a total of 58.400,000 vehicles per year, which would raise £ 175.2 million per year in toll charges.
I am assuming the following.
- All days of a 365-day year have similar traffic.
- Everybody pays without fuss, by technology like number-plate recognition.
- The average toll chare paid is £ 3.
I am drawn to the conclusion, that the contract signed between Transport for London and Riverlinx, is a licence to print money.
Even, if the tunnels only attract 40-50,000 vehicles per day, the revenue is way in excess of the £40 million needed for maintenance, financing and operation of the Silvertown Tunnel.
I have a few further thoughts and questions.
Who Are Riverlinx?
This is said on the About Roverlinx page of the Riverlinx web site.
TfL awarded Riverlinx SPV (Special Purpose Vehicle) the contract for financing and overseeing the design, build and maintenance of the Silvertown Tunnel in 2019.
The Riverlinx CJV (Construction Joint Venture) is contracted by TfL and Riverlinx SPV to complete the design and construction works, delivering the Silvertown Tunnel on time and on budget.
Riverlinx CJV is a joint venture, a partnership bringing together international, market leading expertise from three civil engineering and construction companies: BAM Nuttall, Ferrovial Construction and SK ecoplant.
In collaboration with TfL, our supply chain and other key stakeholders in the project, Riverlinx CJV will complete construction of the Silvertown Tunnel in Spring 2025.
Note.
- BAM Nuttall is a construction and civil engineering company, that is a subsidiary of the Dutch Royal BAM Group.
- Ferrovial Construction is the construction subsidiary of Spanish company; Ferrovial.
- SK ecoplant is a subsidiary of the South Korean conglomorate; SK Group.
These companies should be capable of building the Silvertown Tunnel.
Where Will The Money To Build The Tunnel Come From?
In World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant, using an article in The Times, I explain how Aviva invest our pensions and insurance money in wind farms.
Strangely, a tolled tunnel is a bit like a wind farm financially, in that if it’s working and the wind is blowing or the traffic is coming, it will continue to generate an income.
Built by quality construction companies, as most tunnels are, they will be the sort of investment, that would satisfy the Avivas of this world.
Will Riverlinx Get All The Tolls From The Tunnel?
Nothing is said about how the excess of income over expenditure will go.
I suspect, as the project is being designed, financed and built by Riverlinx, that they will not go unrewarded.
Will The Mayor Set The Toll Charges?
I suspect that the Mayor and TfL will set the charges.
These are some figures with different charges for 70,000 vehicles in each direction per day or a total of 51,100,000 vehicles per year.
- £3 in each direction would raise £ 153.3 million per year in toll charges.
- £4 in each direction would raise £ 204.4 million per year in toll charges.
- £5 in each direction would raise £ 255.5 million per year in toll charges.
- £6 in each direction would raise £ 306.6 million per year in toll charges.
Note.
- Some of the papers are talking of a four pound charge.
- A pound increase may not be much to the average driver, but they will certainly mount up.
Higher toll charges could be used by an unscrupulous Mayor to deter vehicles entering Central London or nudge people towards public transport.
What Happens If The Tunnel Springs A Leak?
I can remember the following tunnels being built under the Thames in my lifetime.
- Blackwall Tunnel – second bore
- Dartford Tunnel
- DLR to Greenwich and Lewisham
- DLR to Woolwich
- Elizabeth Line to Woolwich
- Jubilee Line – four crossings
- Victoria Line to Vauxhall
None of these seven seems to have sprung a leak recently. And neither have the older Victorian tunnels.
Tunnels with an income stream, appear to be a good risk, if they don’t spring a leak.
But London tunnels don’t seem to have a high likelihood of leaking.
Fines
Fines could be a problem, but this article on Kent Online, which is entitled Dartford Crossing Continues To Generate more Than One-Third Of Income From Fines As Profits Total More Than £100m, says otherwise.
Conclusion
This would appear to be a low risk venture and I suspect it will make Riverlinx and TfL a lot of money.
High Speed Two To Manchester
There has been a lot of speculation about the Northern end of High Speed Two, so I might as well add sort out a few facts and add a bit of speculation of my own.
The Current Manchester Piccadilly Services
Currently, there are three trains per hour (tph) between London Euston and Manchester Piccadilly.
The services stop as follows.
- Milton Keynes Central, Rugby, Stoke-on-Trent, Macclesfield and Stockport
- Nuneaton, Stoke-on-Trent and Stockport
- Stafford, Crewe, Wilmslow and Stockport
Note.
- One service goes via Crewe.
- Two services go via Stoke-on-Trent.
- All services go via Stockport.
- A London and Manchester Piccadilly train could go via Milton Keynes Central, Nuneaton, Rugby, Stafford, Stoke-on-Trent, Macclesfield and Stockport.
- A London and Manchester Piccadilly train could go via Crewe, Wilmslow and Stockport.
The two trains detailed would mean that Manchester wouldn’t lose any connectivity.
I would expect that Manchester Piccadilly needs at least three tph to and from London.
This graphic shows High Speed Two services after Phase 2b is completed.
Note.
- Services shown in blue are run by High Speed Two Full Size trains.
- Services shown in yellow are run by High Speed Two Classic-Compatible trains.
- Full Size Services will only run to Manchester Airport and Manchester Piccadilly after Phase 2b is completed to Manchester Piccadilly.
- Classic-Compatible Services will be able to run to to Manchester Piccadilly after Phase 2a is completed.
- Two London and Manchester Piccadilly trains will call at just Old Oak Common and Manchester Airport.
- A third London and Manchester Piccadilly train will call at Old Oak Common, Birmingham International and Manchester Airport.
- Two Birmingham Curzon Street and Manchester Piccadilly trains will call at just Manchester Airport.
- Despite Wilmslow and Stockport being shown in the list of stations on the left hand side of the graphic, no High Speed Two services appear to call at the two stations.
The graphic of High Speed Two services also shows these Full-Size services to Manchester Piccadilly.
- Three tph to London Euston
- Two tph to Birmingham Curzon Street
Some or all of these services will surely be run by High Speed Two Classic-Compatible trains.
What services will run to Manchester between the opening of Phase 2a and the opening of Phase 2b?
I will now give some possibilities for services.
London and Manchester Piccadilly Via Crewe, Wilmslow And Stockport
I shall look at the 07:33 train to Manchester Piccadilly on the 20th September 2023.
- It was a service via Stafford, Crewe, Wilmslow and Stockport
- It was a nine-car Class 390 train or Pendolino, which left on time.
- Euston and Manchester Piccadilly are 188.9 miles apart.
- The train called at Crewe at 09:08 and left at 09:10.
- The average speed between London Euston and Crewe is 70.7 mph.
- The train arrived in Manchester Piccadilly on time at 09:44.
- The journey took two hours and 11 minutes
- The average speed was 86.5 mph.
- The Crewe and Manchester Piccadilly section is 30.9 miles and the train is scheduled to take 34 minutes.
- The average speed between Crewe and Manchester Piccadilly is 54.5 mph.
- The example train slows past Crewe because of two stops at Wilmslow and Stockport.
When Phase 2a of High Speed Two opens a replacement for this service via Crewe, could operate as follows.
- It could use High Speed Two between and Crewe.
- It could use the current route between Crewe and Manchester Piccadilly.
- It would probably use a 200 metre long High Speed Two Classic-Compatible trains.
- I wouldn’t be surprised, that the current Pendolino service between Euston and Manchester Piccadilly via Crewe, Wilmslow and Stockport was retired.
- The new High Speed Two service could take over the path currently used by the current Pendolino service, between Crewe and Manchester Piccadilly.
- The train could stop at Crewe, Wilmslow and Stockport as required.
- If it stopped at Crewe, Wilmslow and Stockport, it would restore some of the connectivity to smaller places.
According to the Wikipedia entry for High Speed Two, these will be the timings.
- London Euston and Crewe – 56 minutes
- London Euston and Manchester Piccadilly Phase 2a – One hour and 30 minutes
- London Euston and Manchester Piccadilly Phase 2b – One hour and 11 minutes
From these figures and the times of the 07:33, I can deduce these journey times for trains via Crewe, Wilmslow and Stockport.
- Currently, Crewe and Manchester Piccadilly takes 34 minutes.
- High Speed Two after Phase 2a will also take 34 minutes.
I am surprised that sectional timings on this section of the West Coast Main Line are the same as current timings. Digital signalling and the faster acceleration and deceleration of the new trains, are quite likely to decrease times.
Because they are both 34 minutes, does that mean that services will stop at Crewe, Wilmslow and Stockport?
London and Macclesfield Via Stafford And Stoke-on-Trent
This map of High Speed Two in North West England was captured from the interactive map on the High Speed Two web site.
Note.
- The map dates from around October 2020.
- The current West Coast Main Line (WCML) and Phase 2a of High Speed Two are shown in blue.
- Phase 2b of High Speed Two is shown in orange.
- The main North-South route, which is shown in blue, is the WCML passing through Crewe, Warrington Bank Quay and Wigan North Western as it goes North.
- The Western Branch, which is shown in blue, is the Liverpool Branch of the WCML, which serves Runcorn and Liverpool.
- High Speed Two, which is shown in orange, takes a faster route between Crewe and Wigan North Western.
- The Eastern Branch, which is shown in orange, is the Manchester Branch of High Speed Two, which serves Manchester Airport and Manchester Piccadilly.
- The route in the East, which is shown in blue, is the Macclesfield Branch of High Speed Two, which serves Stafford, Stoke-on-Trent and Macclesfield.
The route of Northern Powerhouse Rail between Manchester Airport and Liverpool has still to be finalised.
The London and Macclesfield service is as follows.
- There will be one tph
- There are intermediate stops at Stafford and Stoke-on-Trent.
- Macclesfield has a long electrified bay platform, which looks like it will take a 200 m High Speed Two Classic-Compatible train.
- Macclesfield Station And High Speed Two has pictures of the station.
- Four tph operate between Stoke-on-Trent and Manchester Piccadilly via Macclesfield.
- Timings from London would be 55 minutes to Stafford, 70 minutes to Stoke-on-Trent and 90 minutes to Macclesfield.
In some ways, I was surprised about this High Speed Two service.
But it does give an easy connection to Stafford and Stoke-on-Trent.
London and Manchester Piccadilly via Macclesfield, Stafford And Stoke-on-Trent
Currently, Avanti West Coast run a service between London and Manchester which runs as follows.
- It calls at Milton Keynes Central, Rugby, Stoke-on-Trent, Macclesfield and Stockport
- It also passes through Watford Junction, Nuneaton, Tamworth and Lichfield Trent Valley.
- It could pass through Stafford.
- It would mean that Stafford and Stoke-on-Trent were served by 2 tph.
- It is run by a Pendolino.
- It has a frequency of 1 tph.
- The current service takes two hours and 6 minutes.
- A few minutes would be added for each extra stop.
I believe it could be a very useful service.
I wonder if it could be run as a complimentary service to High Speed Two to serve more places on the route.
A Second High Speed Two Service Between London and Manchester Piccadilly Via Crewe, Wilmslow And Stockport
So far, I have mapped out three possible services.
- High Speed Two – London and Manchester Piccadilly Via Crewe, Wilmslow And Stockport – One hour and thirty minutes
- High Speed Two – London and Macclesfield Via Stafford and Stoke – One hour and thirty minutes
- Pendolino – London and Manchester Piccadilly Via Milton Keynes Central, Rugby, Nuneaton, Tamworth, Lichfield Trent Valley, Stafford, Stoke-on-Trent, Macclesfield and Stockport – Two hours and 6 minutes plus 4 minutes for each extra stop.
I suspect that four tph could be a good frequency.
The simplest extra service would probably be another High Speed Two London and Manchester Piccadilly Via Crewe, Wilmslow And Stockport.
But it could be another Pendolino service to serve more places.
I believe a service pattern could be arranged with these features.
- Major cities and towns between London and Manchester have at least two tph.
- A larger number of towns and cities have at least one tph.
Note that many stations on the route already have Pendolino services.
Phase 2b Would Be The Ultimate Solution
Phase 2b which will involve a tunnel via Manchester Airport to new platforms in Manchester Piccadilly could be the ultimate solution.
Phase 2b is also needed so that full-size High Speed Two trains can be run to Manchester Piccadilly.
But it will be difficult, expensive and disruptive to build.
Conclusion
I believe it could be easy to plan four services between London and Manchester Piccadilly or Macclesfield.
- High Speed Two Full-Size train – London and Manchester Piccadilly Via Crewe, Wilmslow And Stockport – One hour and eleven minutes
- High Speed Two Classic-Compatible train – London and Macclesfield Via Stafford and Stoke – One hour and thirty minutes
- High Speed Two Full-Size train – London and Manchester Piccadilly Via Crewe, Wilmslow And Stockport – One hour and eleven minutes
- Pendolino – London and Manchester Piccadilly Via Milton Keynes Central, Rugby, Nuneaton, Tamworth, Lichfield Trent Valley, Stafford, Stoke-on-Trent, Macclesfield and Stockport – Two hours and 6 minutes plus 4 minutes for each extra stop.
Note.
Services 1 and 3 are identical, but don’t need to be.
Service 4 could be run by a High Speed Two Classic-Compatible train.

Could High Speed Two Finish At Lichfield?
High Speed Two To Wigan
There has been a lot of speculation about the Northern end of High Speed Two, so I might as well add sort out a few facts and add a bit of speculation of my own.
The Current Wigan North Western Service
I shall look at the 08:30 train to Glasgow on the 20th September 2023.
- It was an eleven-car Class 390 train or Pendolino, which left on time.
- Euston and Wigan North Western are 193.8 miles apart.
- Trains call at only Warrington Bank Quay
- The train passed Crewe at 09:59
- The train called at Warrington Bank Quay at 10:14 and left at 10:15.
- The train arrived at Wigan North Western at 10:25 on time.
- The journey took one hour and 55 minutes
- The average speed was 101.1 mph.
- The Crewe and Wigan North Western section is 35.8 miles and the train is scheduled to take 26 minutes.
- The average speed between Crewe and Wigan North Western is 82.6 mph.
The train slows past Crewe because of the stop at Warrington Bank Quay.
London Euston And Wigan North Western After Phase 2a Of High Speed Two Opens
According to the Wikipedia entry for High Speed Two, these are the timings.
- London Euston and Crewe – 56 minutes
- London Euston and Warrington Bank Quay – One hour and 20 minutes
- London Euston and Wigan North Western – One hour and 34 minutes
From these figures and the times of the 08:30, I can deduce these journey times.
- Currently, Crewe and Warrington Bank Quay takes 16 minutes and High Speed Two will take 24 minutes
- Currently, Warrington Bank Quay and Wigan North Western takes 10 minutes and High Speed Two will take 14 minutes
- Currently, Crewe and Wigan North Western takes 26 minutes and High Speed Two will take 38 minutes
I am surprised that sectional timings on this short section of the West Coast Main Line are slower than current timings. Digital signalling and the faster acceleration and deceleration of the new trains, are more likely to decrease times, than increase them.
London Euston And Preston After Phase 2a Of High Speed Two Opens
According to the Wikipedia entry for High Speed Two, these are the timings.
- London Euston and Crewe – 56 minutes
- London Euston and Warrington Bank Quay – One hour and 20 minutes
- London Euston and Wigan North Western – One hour and 34 minutes
- London Euston and Preston – One hour and 18 minutes
This graphic shows High Speed Two services.
Note that Preston gets two non-stop services to and from London and another with stops at Warrington Bank Quay and Wigan North Western, and a train split/join at Crewe.
The one hour and 18 minutes surely applies to one or both of the non-stop services.
140 Mph Running Between Crewe And Preston
Consider.
- London Euston and Crewe is 56 minutes
- One hour and 18 minutes to Preston infers a time of 22 minutes between Crewe and Preston.
- Crewe and Preston is 51 miles.
This implies an average speed of 139 mph.
As the West Coast Main Line was built for 140 mph, when digital signalling was installed, this would appear to be feasible, once the signalling is upgraded.
It may also mean, that faster times are possible in services to Warrington Bank Quay and Wigan North Western.
Consider.
- Crewe and Wigan North Western is 35.8 miles
- High Speed Two will take 38 minutes
- The average speed between Crewe and Wigan North Western will be just 56.5 mph.
But if it could run at 140 mph mph between Crewe and Wigan North Western, the base time would be just over 15 minutes.
To this time must be added two full station stops and the time it takes to split or join.
With the superior acceleration and deceleration of the High Speed Two trains and their level of automation, these operations will not take 23 minutes.
I believe that this means that minutes can be saved on services to Lancaster, Liverpool Lime Street, Warrington Bank Quay and Wigan North Western.
London Euston And Wigan North Western After Phase 2b Of High Speed Two Opens
There will be no changes as the full-size High Speed Two trains are not planned to run to the North of Crewe.

Severn Valley Railway Announces Network Rail Partnership
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A heritage railway is to work in partnership with Network Rail to share expertise and resources.
These are the first two paragraphs.
Severn Valley Railway, which runs trains between Kidderminster and Bridgnorth, said it would receive spare materials, trackside equipment and track components.
In exchange, Network Rail will be able to train its teams on the railway.
This sounds like the sort of sensible deal, that was negotiated in a real ale pub, by engineers from both parties.
The article also has this paragraph.
The railway said this contract was the first of its kind in Britain and could become a model for other heritage railways to adopt.
I certainly agree with that statement.
I have also written two posts about co-operation with the Mid-Norfolk Railway.
- Aerial Pictures Show New Trains Housed In Mid-Norfolk.
- Mid Norfolk Railway Completes Work On ‘First For UK’ Railway Level Crossing.
It also appears from its Wikipedia entry that the Mid-Norfolk Railway, is regularly used to load freight for transport out of Norfolk. Items moved include Army vehicles and damaged rolling stock.
