BAE To Produce Batteries For Electric Passenger Plane
The title of this post, is the same as that of this article on The Times.
This is the first paragraph.
BAE Systems is stepping back into the world of passenger aircraft manufacturing by partnering with a Swedish electric planemaker.
I must admit, that I’m not surprised about BAE Systems’s decision.
Aviation needs batteries for many purposes including drones, starting aircraft and auxiliary power sources, so I wouldn’t be surprised that BAE Systems know their batteries.
In The Big Beast In Your Electric Bus, I described the company’s involvement in providing batteries for electric buses in the United States.
As a former private pilot, I’m watching electric aviation with interest.
I am also an applied mathematician and control engineer and feel that electric aviation will always be playing catch up against planes powered by hydrogen and sustainable aviation fuel.
Look at some of Airbus’s ZeroE designs, which use hydrogen fuel.
Discover the three zero-emission concept aircraft known as ZEROe in this infographic. These turbofan, turboprop, and blended-wing-body configurations are all hydrogen hybrid aircraft.
Although saying that there are large numbers of orders for electric airliners like this Swedish design and the Eviation Alice.
Riding The 182 Bus Between Harrow Bus Station And Brent Cross
I did this journey, which could be part of the Superloop, in good weather, and was able to take these pictures.
Note.
- The roads were not bad and were partly two lanes each way, with large roundabouts at junctions.
- I suspect the bus was going at between 30 and 40 mph most of the way.
- There was still quite a lot of traffic.
- It is a distance of about 7 miles.
- The timetable says that buses run every 10-13 minutes.
- Harrow-On-The-Hill station is next to Harrow Bus station.
- Harrow-On-The-Hill connects to the Metropolitan Line and Chiltern
- Northwick Park Hospital is on the route.
- Sudbury and Harrow Road station connects to Chiltern.
- South Harrow station connects to the Piccadilly Line.
- Wembley Central station connects to the Bakerloo and Watford DC Lines and National Rail.
- Wembley Stadium station connects to Chiltern.
- Wembley Park station connects to the Metropolitan and Jubilee Lines.
The journey took about 70 minutes, mainly because of the traffic at the road works.
I have a few thoughts.
The Route Of The Bus 182 Could Be Part Of The Superloop
I feel my journey today, proved that this would be part of a feasible Superloop leg between Harrow and North Finchley bus stations.
A Chiltern Metro
Wikipedia says this about a proposed metro service between Marylebone and West Ruislip stations.
- The Metro would have a frequency of four tph.
- It would call at Wembley Stadium, Sudbury & Harrow Road, Sudbury Hill Harrow, Northolt Park and South Ruislip.
- The service would require a reversing facility at West Ruislip.
- There would need to be passing loops at Sudbury Hill Harrow, and Wembley Stadium.
Given that the Chiltern Metro was first proposed over a decade ago, perhaps the concept could be increased in scope.
- Housing and other developments along the route may suggest that a station further out like High Wycombe might be a better terminal.
- ERTMS in-cab digital signalling is likely to be installed at some time, which would decrease headways between trains and allow more services.
- Electrification is likely in some form before 2040 and this will improve train performance.
- If Neasden station were to be rebuilt, as a comprehensive transport and residential development, I believe that this Metro service should also call at Neasden, as it would complement the West London Orbital Railway.
I believe that a review of the Chiltern Metro may mean, that an improved version is worth creating.
TfL Needs More Elizabeth Line Trains Because Of HS2 Delays At Euston
The title of this post, is the same as that of this article on Ian Visits.
This is the first paragraph.
Transport for London (TfL) is warning that delays to the HS2 railway may require it to buy more Elizabeth line trains to cope with the thousands of people dropped off at Old Oak Common needing to get into central London.
Given, the way they got the project management and the cost and schedule so wrong, I wonder if we can rely on this assertion.
I certainly find fault with this statement.
In an ideal world, TfL would be able to send some empty Elizabeth line trains stabled in a depot to the west of Old Oak Common station, but the location of the main depot rules that out.
The Wikipedia entry for the Elizabeth Line says this about the future service.
In May 2023, it is planned to allow trains to run from both eastern branches to west of Paddington. This will allow both more flexible, and higher frequency, services: 24 tph peak, 20 tph off-peak, and direct services between Shenfield and Heathrow. In the longer term, when Old Oak Common opens, all trains will serve Old Oak Common, with those not serving the Reading or Heathrow branches reversing there.
The service changes for 21 May 2023 were confirmed in February 2023. The peak timetable will increase to 24 trains per hour. Off-peak service level will remain at 16 trains per hour, with two Shenfield–Paddington trains extended to Heathrow Airport Terminal 5 and two Abbey Wood–Terminal 5 trains switching to Terminal 4.
Consider.
At present 8 trains per hour (tph), pass through the site of Old Oak Common station.
By reversing the trains at Old Oak Common, rather than Paddington, this will surely mean that after the 21st of May 2023, 24 tph in the Peak and 20 tph in the Off Peak will pass through Old Oak Common.
If eight tph, still go on to Heathrow, Maidenhead and Reading, 16 tph will be turned in the Prak and 8 tph in the Off Peak.
This would give more capacity, as more trains would be running between Old Oak Common and Whitechapel.
If TfL have collected the right statistics, I’m sure they can predict the number of trains needed.
It seems to me, that the most important thing that TfL can do is make sure they can turn all the trains they need to at Old Oak Common station.
How Are Trains Going To Be Reversed At Old Oak Common?
The Victoria Line can handle 33 tph between Brixton and Walthamstow Central and the Elizabeth Line could use a similar method to handle the 16 tph, it needs to turn at Old Oak Common.
A process called stepping-up is used on the Victoria Line.
- On arrival in the terminal platform, the driver shuts the train down and leaves the cab.
- A second driver gets in the cab at the other end of the train and readies the train for departure.
- When instructed by the signalling, the new driver initiates the process by which the train leaves the station.
The original driver of the train, walks to the other end of the platform, to get themselves ready to be called to step-up to another train, at an appropriate time in the future.
I suspect to use stepping-up at Old Oak Common for the Elizabeth Line will need four platforms; two through platforms for services beyond Old Oak Common and two adjacent bay-platforms for services to be turned.
In Crossrail Trains Cleared To Use The Heathrow Tunnel, I gave this detailed description from Ian of the Class 345 trains‘ Auto-Reverse feature.
Around half of westbound trains will terminate at Paddington, but to head back eastwards, once all the passengers are off, they carry on westwards to Westbourne Park, then return back to Paddington on the eastbound line.
Normally that means the train driver would drive to Westbourne Park, stop, walk through the train to the other end, then drive back. But with “auto-reverse”, as soon as the train leaves Paddington, the driver switches to automatic and starts walking through the train to the other end. By the time the train arrives at Westbourne Park sidings, the driver will be sitting in the drivers cab at the other end of the train ready to head back into Central London.
I suspect that the Elizabeth Line will use Auto-Reverse or some other nifty piece of automation at Old Oak Common.
Superloop – Will It Be The North Circular Road Most Of The Way Between Harrow And Royal Docks?
This draft map from TfL illustrates the concept of Superloop.
In this post I am considering the section of the the North Circular Road (A406) between the Hangar Lane Gyratory System, where it crosses the A40 in the West and the roundabout , where it crosses the A13 at Beckton in the East.
- This section is a grade-separated dual-carriageway all of the way between Hangar Lane and Beckton.
- Hendon, North Finchley, Arnos Grove, Edmonton, Walthamstow, Ilford and Royal Docks are not far from the A406.
- Several bus routes already run on the A406.
The large Brent Cross Shopping Centre is also just outside the A406 and a new Brent Cross West station will be opening soon.
I’ll now look at the three Northern and North-Eastern sections.
Harrow And North Finchley
This section is shown in orange.
- It calls at Northwick Park hospital and Hendon. both have rail connections.
- Brent Cross Shopping Centre could be on the route, if the A406 is used.
- London Bus 182 runs between Harrow bus station and Brent Cross Shopping Centre via Northwick Park hospital.
Could the 182 bus be extended to North Finchley, where there is a new bus station?
This Google Map shows the stations around the Brent Cross Shopping Centre.
Note.
- The railway running between the North-West corner of the map and the bottom of the map is the Midland Main Line.
- The road running between the North-East corner of the map and the left of the map is the North Circular Road.
- The road running down the right hand side of the railway is the M1, which joins the A406 in the large junction.
- The other major road to the right of the map, is the Hendon Way.
- The station in the North-West corner of the map is Hendon.
- The station being built in the bottom of the map on the Midland Main Line, is the new Brent Cross West station.
- The station in the North-East corner of the map is Brent Cross on the Northern Line.
I am certain that a Superloop bus could run from Harrow bus station and Northwick Park hospital, and visit the required number of the stations around the Shopping Centre, before trundling on to the new North Finchley bus station for some refreshment before returning to Harrow.
I feel that the Superloop bus could use the North Circular Road from the shopping centre and then turn North on to Finchley High Road (A 1000).
North Finchley And Walthamstow
This section is shown in red.
- It calls at Arnos Grove and Edmonton.
- London Bus 34 runs between Walthamstow bus station and Barnet. It runs for some of the way along the North Circular Road and passes Arnos Grove, Silver Street and the North Middlesex Hospital.
I am certain, that a Superloop bus could run between Walthamstow bus station and North Finchley, using a similar route to the 34.
Walthamstow And Royal Docks
This section is shown in lime.
- It calls at Ilford for the Elizabeth Line.
I am certain, that a Superloop bus could run between Walthamstow bus station and Royal Docks, using a the A406 and the A13.
Conclusion
After this simple analysis, it looks possible to use the use the North Circular Road between Harrow and Royal Docks.
Riding The X140 Bus Between Heathrow Airport And Harrow Bus Station
I did this journey, which will be part of the Superloop, in better weather than yesterday, and was able to take these better pictures.
Note.
- The roads were much better than yesterday’s trip and were mostly two lanes each way, with large roundabouts at junctions.
- I suspect the bus was going at between 30 and 40 mph most of the way.
- There was still quite a lot of traffic.
- It is a distance of about 15 miles.
- The timetable says that buses run every 10-13 minutes.
- The X26 buses run between about six in the morning at midnight.
- There are twelve intermediate stops.
- Harrow-On-The-Hill station is next to Harrow Bus station.
- Heathrow Central connects to Heathrow Express, the Elizabeth and Piccadilly Lines.
- Hayes and Harlington connects to the Elizabeth Line and GWR’s local services.
- Northolt station connects to the Central Line.
- Northolt Park station connects to Chiltern.
- South Harrow station connects to the Piccadilly Line.
- Harrow-On-The-Hill connects to the Metropolitan Line and Chiltern
The journey took 49 minutes, which is only a minute longer than the timetable.
I have a few thoughts.
Passenger Numbers
These were my observations on my journey that started at about 11:30 on a dry day.
- Few got on at Heathrow Central, but I suspect we had just missed a bus.
- By Hayes & Harrington station, the bus was about a quarter full.
- At South Harrow station it must have been about three-quarters full.
- At Harrow bus station all the lower-deck seats were taken.
I would expect that the loading I saw fits with TfL’s expectations.
The Bus
The bus was one of the latest ADL battery-electric buses.
- It had a strong performance.
- It had wi-fi and phone charging.
- It was probably less than a year old.
- It was a lot better than yesterday’s bus!
At present not all buses on the route are battery-electric, as some are still older hybrids.
Travelling To Heathrow From The Northern Reaches Of The Metropolitan Line
Many people travel to and from Heathrow either for work or because they are flying.
- But it is not an easy journey from the Northern reaches of the Metropolitan Line.
- I believe the X26 bus could be a viable way to get to the airport for many.
- There would be a change at Harrow-on-the-Hill, but the station is at least step-free.
- It would avoid parking fees.
- Fares could be less than fuel costs.
The only big drawback, is that the X26 bus is not twenty-four hours.
More And More Frequent Buses Would Help
I believe that the Superloop should be a 24-hour service, as a lot of things go on at airports in the middle of the night.
I’ve just found out that there is an N140 bus that covers the route.
I also think, that as with the Overground, services should be at least four buses per hour.
Riding The X26 Bus Between West Croydon Bus Station And Heathrow Airport
I did this journey, which will be part of the Superloop, in the pouring rain yesterday, and took these were the awful pictures.
Note.
- The rain didn’t help, but the journey was so slow and it is timetabled for an hour and forty minutes.
- There was a lot of traffic and this meant we were a few minutes late.
- I was sitting up front, with another pensioner, who was going to have lunch with mates in Kingston.
It may be an express bus, but I can’t see the speed of this section attracting a lot of passengers.
When I took my ride across Birmingham in a hydrogen bus, which I wrote about in Riding Birmingham’s New Hydrogen-Powered Buses, where I said this about the Wrightbuses.
I very much feel that the buses are the best hydrogen-powered vehicles, that I’ve travelled in, as they are smooth, comfortable, quiet and seem to have excellent performance.
There were some sections of dual-carriageway in Birmingham, where the buses were able to use their excellent acceleration to get through the traffic and make up many seconds.
It should also be noted, that Dublin uses the same hydrogen buses for a long-distance commuter bus.
West Croydon Bus Station – 28th March 2023
This morning I went to West Croydon Bus Station, to catch the X26 bus between West Croydon station and Heathrow Airport.
This was to investigate TfL’s Superloop.
I took these pictures of the bus station.
It was nice to see a well-designed bus station, that had been built to a high standard.
New Fast Bus Service To Link London’s Outer Boroughs
The title of this post is the same as that of this article on the BBC.
This is the sub-heading.
A new fast service bus network has been announced for London’s outer boroughs.
These three paragraphs outline the concept.
Six new routes will be created and four incorporated into the ‘Superloop’ network, complete with distinct branding.
The plans propose a fast service to make more stops linking many of the peripheral boroughs.
The network is part of London Mayor Sadiq Khan’s effort to compensate for the impact of the ultra-low emission zone expansion, due to start in August.
This draft map from TfL illustrates the concept.
In the draft map, the following can be discerned.
- Arnos Grove station is in the North.
- West Croydon station is in the South.
- Royal Docks and Bexleyheath are in the East.
- Uxbridge and Hayes & Harlington stations are in the West.
- Elizabeth Line stations on the route include Ilford, Custom House, Heathrow Airport and Hayes & Harlington.
The plan may work well, as in the 1950s and 1960s, I used the 107 bus route very regularly, as it cut a circular path between Queensbury in the West and Enfield in the East.
I have some thoughts.
Royal Docks And Bexleyheath
This Google Map shows the Royal Docks.
Note.
- The dotted red line indicates the Royal Docks.
- The runway of the London City Airport can be seen.
- Custom House station on the Elizabeth Line is served by the Elizabeth Line and the Docklands Light Railway.
This second Google Map shows the Western end of the Royal Victoria Dock.
Note.
- Custom House station is in the North-East corner of the map.
- The Excel is on the East end of the map.
- London City Hall is at the Western end of the Royal Victoria Dock.
- The cable-car to Greenwich connects to the area.
I would suspect that the bus from Walthamstow will terminate close to City Hall and the cable-car.
This Google Map shows the Royal Docks and Bexleyheath.
Note.
- The dotted red line indicates the Royal Docks.
- Bexleyheath station is in the South-East corner of the map.
I wouldn’t be surprised to see the Mayor organise a bus, through his new pet project; the Silvertown Tunnel.
Electric Or Hydrogen
Ideally, the buses will need to be zero-carbon; which means battery-electric or some form of hydrogen power.
Birmingham has a similar series of express routes, that run across the city, which I wrote about in Riding Birmingham’s New Hydrogen-Powered Buses.
I feel that long routes like some of these are should be run with hydrogen-powered buses, because of there longer range.
High Speed Two – Old Oak Common – 28th March 2023
I took these pictures from an Elizabeth Line train, as it passed High Speed Two’s massive Old Oak Common site.
Note, the large conveyor in the first seven pictures is used to remove soil from the site.
Adding Southport And Stalybridge Via Atherton To The Bee Network
This article on the Railway Gazette has a list of the lines, that will be transferred between Northern Rail and the Bee Network.
Included in the list is this line.
Southport And Stalybridge Via Atherton.
I think this route could be the following.
- The Eastern terminal would be Stalybridge.
- The Northern terminal would be Southport.
- Intermediate stations would be Meols Cop, Bescar Lane, New Lane, Burscough Bridge, Parbold, Appley Bridge, Gathurst, Wigan Wallgate, Hindley, Daisy Hill, Hag Fold, Atherton, Walkden, Swinton, Salford Crescent, Salford Central, Manchester Victoria and Ashton-under-Lyne
- The route is partly electrified with 25 KVAC overhead.
- Mich of the route has a 75 mph operating speed.
Currently, this service runs hourly, by a slightly different route to that proposed.
This is my thought.
Battery-Electric Trains
Consider.
- The route could be ideal for battery-electric trains.
- Central Manchester and Stalybridge will soon be electrified.
- A charging station could be added at Southport station.
Merseyrail’s Class 777 trains or something similar would surely do nicely.
