Introducing JetZero
The Times today has an article which is entitled Up, Up And Away On An Eco-Friendly, Blended-Wing Jet.
This is the sub-heading.
The US air force hopes that a $235 million contract for a radical new design will take off
The article goes on to give a good history of blended wing bodies, before describing JetZero’s blended-wing jet and the company’s deal with the US Air Force.
More on the aircraft is available on the company’s web site. Take a look at the WHY JETZERO page.
In ZEROe – Towards The World’s First Zero-Emission Commercial Aircraft, I describe Airbus’s ZEROe BWB, which is another proposed blended wing body.
London Overground Lines To Be Given Unique Names
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Six London Overground lines are to be given unique names.
These three paragraphs explain it all.
Routes to be named include Euston to Watford Junction, Romford to Upminster and Gospel Oak to Barking, City Hall confirmed.
Seb Dance, deputy mayor for transport, said posters had been put up in stations informing people of the plans and encouraging them to get involved.
London Overground will remain as the umbrella brand, according to transport bosses.
It will cost £6.3 million.
What a waste of money!
I suppose they will all be given nice politically correct names, that no-one will use and those on thee far-right will cover with graffiti.
Yesterday, I needed to use The Drain, so I asked if it was open at Waterloo. Perhaps the first thing, that they ought to do, is teach staff all the colloquial names that my parents’ generation used.
The sooner the good voters of London give SadIQ his marching orders the better.
Selling Office Space
I took these pictures of the hoarding around the new 101 Moorgate office block, that is being built outside Moorgate station.
101 Moorgate is certainly easy for the Elizabeth Line and other public transport.
It will be interesting to see, when the building is let!
Biarritz And My Family
I am coeliac and I am fairly sure, my father was too, as he had all the wind, I had at fifty, which was something that led to my being diagnosed as coeliac.
But as my father was born in 1904, there was not really any tests for the disease.
I was one of many, who were diagnosed at Addenbrooke’s Hospital in the 1990s, where I am certain, they were testing out, the genetic test for the disease.
How else could I go in on a Monday and have a very short chat and give some blood for testing and then get a letter on the Wednesday saying I was probably coeliac and it would be confirmed by endoscopy.
I never met my paternal grandfather, as he died in 1929 at around fifty.
My father told me a lot about his father. He had been very affected by his father’s heavy drinking and alcoholism. I suspect, it was part of his plan to make sure, that I didn’t go the way of his father.
In fact now at 76, I am virtually teetotal, although I do drink a lot of bottles of 0.5 % alcohol real ale. But this doesn’t affect my gut or my INR.
I know little about my grandfather’s health, but he did suffer from asthma and that was what killed him.
Was he coeliac? From my father’s descriptions of his father, it was highly likely.
My grandfather had a profitable printing business, which even in the 1920s had around a hundred employees according to what my father told me.
My father also remembered going to see Spurs at White Hart Lane in a pony and trap. That at least showed a certain status.
My paternal grandparents also used to go to Biarritz for at least part of the winter.
My father did say a couple of times, that it did improve my grandfather’s health.
But when I went to Biarritz ten years ago, it certainly made me feel better.
I wrote Would I Go Back To Biarritz Again?.
Alstom And VMS Present New Battery-Powered Train
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the sub-heading.
Alstom and the Central Saxony transport authority, Verkehrsverbund Mittelsachsen (VMS) in Germany have unveiled a new battery-powered train developed by Alstom.
These first four paragraphs are very information rich.
A total of eleven Coradia Continental battery-electric trains have been ordered by VMS. These trains will enter service in 2024 on the Chemnitz-Leipzig line.
The Coradia Continental battery-electric train has a range of up to 120 kilometres and can be operated under catenary as well as on non-electrified sections of line. The three-car trains are 56 metres long and can seat up to 150.
The new train can also reach maximum speeds of 160 km/h in battery mode. The capacity of the high-performance lithium-ion batteries is calculated to guarantee catenary-free operation on the Chemnitz-Leipzig line without sacrificing performance.
Müslüm Yakisan, president of Alstom Region DACH, said: “Alstom’s ambition is to be the global leader in sustainable mobility, reducing emissions and pollution in catenary-free operation. The presentation of the first battery-powered train developed by Alstom is an important step in this direction.
These seem to be a very useful battery-electric train.
- Battery or catenary operation
- Three-cars of 19 metres
- Fifty seats per car
- 100 miles per hour
A three-car Class 730 train has the following characteristics.
- three cars of 20 metres
- 199 seats.
- 90 miles per hour
Can we have a battery version soon? Please!
Cunning Electrification On The North London Line
I took a trip on the North London Line from Highbury & Islington station to Richmond station.
I took various pictures on the way.
25 KVAC Overhead Electrification
East of Acton Central station, typical 25 KVAC overhead electrification is used.
It may need to be beefed up, if more large electric locomotives haul freight trains along the North London Line.
Gunnersbury Station
Gunnersbury station is a two-platform station with London Underground four-rail electrification.
It can be used by London Underground S-Stock and London Overground Class 378 trains.
It must help that both trains were built by Bombardier in Derby.
Kew Gardens Station
Kew Gardens station is a two-platform station with London Underground four-rail electrification.
As with Gunnersbury station, both types of train can use both platforms.
Richmond Station
Richmond station is both a through and terminal station.
Note.
- Platforms 1 and 2 are through platforms for South Western main line services.
- Platforms 3 to 7 are for terminating London Underground and Overground services.
- Platforms 1 to 3 have traditional third-rail electrification.
- Platforms 4 to 7 have London Underground four-rail electrification.
- If needed, it may be possible to add another platform between platforms 3 and 4.
It looks like a lot of flexibility has been built in.
I have a few general thoughts.
Getting The Voltages Right
London Underground’s system used to use 630 VDC for its four-rail system, whereas Network Rail’s system uses 750 VDC.
I wouldn’t be surprised to find out that both trains use quality power electronics that can work on a range of voltages. This would enable London Underground to up their voltage to the same 750 VDC as used by Network Rail.
In Chiltern Sets Out New Fleet Ambitions, I talked about how Chiltern Railways could use London Underground’s four-rail electrification between Harrow-on-the-Hill and Amersham stations to charge the batteries.
As an electrical engineer, I don’t think this is outrageous.
