A Stray TransPennine Express Class 802 Train In London
I took these pictures of a TransPennine Express Class 802 train running around London.
In the first three pictures, it was parked in the sidings to the East of Southall station.
The rest were taken at Willesden Junction station.
Looking at Real Time Trains it appeared to be going between the Hitachi depots at North Pole and Doncaster.
Is This The Longest Bus Stop Repair in London’s History?
This picture shows the bus stop outside Dalston Junction station.
I use this bus stop regularly and since about 2012, the top bit above the information has been missing.
But not any more!
Crossrail’s Paddington Service Plans Revealed
The title of this post is the same as that of this article on Rail Magazine.
This is the first paragraph.
Trains from London Paddington Crossrail station to Shenfield will begin six months after trains start serving the low-level station from other destinations.
In Crossrail Ltd Outlines Plan To Complete The Elizabeth Line,, which I wrote in April 2019, I quoted these points from a statement on the Crossrail web site.
- Crossrail Ltd has identified a six-month delivery window with a midpoint at the end of 2020.
- Bond Street station will open later.
- Service will be initially twelve trains per hour (tph) between Paddington and Abbey Wood stations.
- Services between Paddington and Reading will commence in December 2019 with a frequency of 4 tph in the peak.
None of these promises from six months ago appear to have been changed.
So my comment at the time still stands.
Twelve trains per hour (tph) gives a capacity of 18,000 passengers per hour, which compares with the 36 tph and 31,500 passengers per hour of the Victoria Line.
Practically, this means that a twelve tph Crossrail could be carrying sixty percent of the number of passengers of the Victoria Line. It’s better than a kick in the teeth!
But then Dear Old Vicky is the Platinum Standard with lots of encrusted diamonds!
There is also other information in the Rail Magazine article.
- Paddington to Shenfield services will start six months after the start of Paddington to Abbey Wood services.
- Services will initially use the two-platform Crossrail station under Paddington as a terminus.
- Through services are expected to start a year later.
It looks like Crossraill should be fully open by the May 2022 timetable change.
This map from carto.metro.free.fr shows the layout of the lines at Paddington station.
Note that if you go pass the Crossrail tunnel portal on a train, there are generally several of Crossrail’s Class 345 trains to be seen, lined up in front of Westbourne Park bus garage.
These pictures were taken in July 2019.
Fracking Hell…Is It The End?
The title of this post, is the same as that of this article in yesterday’s Sunday Times.
The article is an interesting read.
These two paragraphs are key.
Activism by Extinction Rebellion and growing public concern about climate change have weakened the chances of an industry once expected to create 64,500 jobs ever getting off the ground.
Cuadrilla Resources, the fracking company most active in Britain, has in recent days been removing equipment from its sole operating site in Lancashire. Petrochemicals tycoon Sir Jim Ratcliffe has vowed to pursue shale gas exploration overseas because of “archaic” and “unworkable” regulations at home.
But I think it’s more complicated than that!
I sometimes go to lectures at the Geological Society of London and two stand were about fracking.
Two were about fracking.
Fracked or fiction: so what are the risks associated with shale gas exploitation?- Click for more.
This is a video of the lecture.
What Coal Mining Hydrogeology Tells us about the Real Risks of Fracking – Click for more.
This is a video of the lecture.
This is a must-watch video from a good speaker.
I have also written several posts about fracking, with some of the earliest being in 2012-2013.
I have just re-read all of my posts.
- In the posts I have tried to give information and at times, I have said we should start fracking.
- But we should only start if we know what we’re doing.
- In several places I ask for more research.
However, there are some interesting facts and inconvenient truths about fracking and natural gas in general.
- Russia earns about €300billion a year or twenty percent of its GDP from gas exports to Europe. See Should We Nuke Russia?.
- Putin backs the anti-fracking movement. See Russia ‘secretly working with environmentalists to oppose fracking’.
- Fracking techniques is used in the Scottish Highlands to obtain clean water from deep underground. See the second Geological Society of London video.
- About forty per cent of gas usage is to heat housing. See the second video.
- The eighteen percent of the UK population, who don’t have a gas supply are more likely to be in fuel poverty. See the second video.
- Scotland has more need for energy to provide heat. See the second video.
- Natural gas with carbon capture and storage has a similar carbon footprint to solar power. See the second video.
- Cowboy fracking, as practised in the United States, would not be allowed in the UK or the EU. See the second video.
- We have no historic earthquake database of the UK, which would help in regulation and research of fracking. See the second video.
- Fracking has brought down the price of gas in North America.
- In the United States fracked gas is cutting the need to burn coal, which produces more pollution and carbon dioxide to generate the same amount of energy. See A Benefit Of Fracking.
The article in the Sunday Times says pressure against fracking has started the shutdown of the industry in the UK.
But there is another big pressure at work.replacement of natural gas with hydrogen.
- This would reduce carbon emissions.
- It can be used as a chemical feedstock.
- It could be delivered using the existing gas network.
- The gas network could be changed from natural gas to hydrogen on a phased basis, just as the change from town to natural gas was organised around fifty years ago.
But it would mean that all gas users would need to change their boilers and other equipment.
Put yourself in the position of Jim Ratcliffe; the major owner and driving force behind INEOS.
INEOS needs feedstocks for chemical plants all over the world and affordable natural gas is one that is very suitable, as it contains two of the major elements needed in hydrocarbons and many useful chemicals; carbon and hydrogen.
If local sources are not available, then liquefied natural gas can be shipped in.
The Hydrogen Economy
It is possible to replace natural gas in many applications and processes with hydrogen.
- It can be used for heating and cooking.
- Important chemicals like ammonia can be made from hydrogen.
- It can be transported in existing natural gas etworks.
- Hydrogen can also replace diesel in heating and transport applications.
There is also a possibility of measures like carbon taxes being introduced, which using hydrogen would reduce.
There’s more in the Wikipedia entry for Hydrogen economy.
Have Jim Ratcliffe and others done their predicting and decided that the demand for locally sourced natural gas will decline and that the hydrogen economy will take over?
But there will need to be a readily available source of large amounts of hydrogen.
I used to work in a hydrogen factory at Runcorn, which was part of ICI, that created hydrogen and chlorine, by the electrolysis of brine. In some ways, the hydrogen was an unwanted by-product, back in the late 1960s, but similar and more efficient processes can be used to convert electricity into hydrogen.
The latest idea, is to cluster offshore wind farms around gas rigs in the seas around the UK. The electricity produced would be used to electrolyse water to extract the hydrogen, which would then be piped to the shore using existing gas pipelines.
It would be a way of reusing infrastructure associated with gas fields, that have no gas left to extract.
There would be no need to build an expensive electricity cable to the shore.
The Dutch, Danes and the Germans are proposing to build the North Sea Wind Power Hub, which is described like this in Wikipedia.
North Sea Wind Power Hub is a proposed energy island complex to be built in the middle of the North Sea as part of a European system for sustainable electricity. One or more “Power Link” artificial islands will be created at the northeast end of the Dogger Bank, a relatively shallow area in the North Sea, just outside the continental shelf of the United Kingdom and near the point where the borders between the territorial waters of Netherlands, Germany, and Denmark come together. Dutch, German, and Danish electrical grid operators are cooperating in this project to help develop a cluster of offshore wind parks with a capacity of several gigawatts, with interconnections to the North Sea countries. Undersea cables will make international trade in electricity possible.
Later, Wikipedia says that ultimately 110 GW of electricity capacity could be developed.
So could these planned developments create enough hydrogen to replace a sizeable amount of the natural gas used in Western Europe?
I suspect a lot of engineers, company bosses and financiers are working on it.
Conclusion
I have come to the following conclusions.
- Fracking for hydrocarbons is a technique that could be past its sell-by date.
- The use of natural gas will decline.
- INEOS could see hydrogen as a way of reducing their carbon footprint.
- The heating on all new buildings should be zero carbon, which could include using hydrogen from a zero-carbon source.
There are reasons to think, that electricity from wind-farms creating hydrogen by electrolysis could replace some of our natural gas usage.
A Selection Of Train Noses
I have put together a selection of pictures of train noses.
They are in order of introduction into service.
Class 43 Locomotive
The nose of a Class 43 locomotive was designed by Sir Kenneth Grange.
Various articles on the Internet, say that he thought British Rail’s original design was ugly and that he used the wind tunnel at Imperial College to produce one of the world’s most recognised train noses.
- He tipped the lab technician a fiver for help in using the tunnel
- Pilkington came had developed large armoured glass windows, which allowed the locomotives window for two crew.
- He suggested that British Rail removed the buffers. Did that improve the aerodynamics, with the chisel nose shown in the pictures?
The fiver must be one of the best spent, in the history of train design.
In How Much Power Is Needed To Run A Train At 125 mph?, I did a simple calculation using these assumptions.
- To cruise at 125 mph needs both engines running flat out producing 3,400 kW.
- Two locomotives and eight Mark 3 carriages are a ten-car InterCity 125 train.
This means that the train needs 2.83 kWh per vehicle mile.
Class 91 Locomotive
These pictures show the nose of a Class 91 locomotive.
Note, the Class 43 locomotive for comparison and that the Driving Van Trailers have an identical body shell.
It does seem to me, that looking closely at both locomotives and the driving van trailers, that the Class 43s look to have a smoother and more aerodynamic shape.
Class 800/801/802 Train
These pictures show the nose of a Class 800 train.
In How Much Power Is Needed To Run A Train At 125 mph?, I did a simple calculation to find out the energy consumption of a Class 801 train.
I have found this on this page on the RailUKForums web site.
A 130m Electric IEP Unit on a journey from Kings Cross to Newcastle under the conditions defined in Annex B shall consume no more than 4600kWh.
This is a Class 801 train.
- It has five cars.
- Kings Cross to Newcastle is 268.6 miles.
- Most of this journey will be at 125 mph.
- The trains have regenerative braking.
- I don’t know how many stops are included
This gives a usage figure of 3.42 kWh per vehicle mile.
It is a surprising answer, as it could be a higher energy consumption, than that of the InterCity 125.
I should say that I don’t fully trust my calculations, but I’m fairly sure that the energy use of both an Intercity 125 and a Class 801 train are in the region of 3 kWh per vehicle mile.
Class 717 Train
Aerodynamically, the Class 700, 707 and 717 trains have the same front.
But they do seem to be rather upright!
Class 710 Train
This group of pictures show a Class 710 train.
Could these Aventra trains have been designed around improved aerodynamics?
- They certainly have a more-raked windscreen than the Class 717 train.
- The cab may be narrower than the major part of the train.
- The headlights and windscreen seem to be fared into the cab, just as Colin Chapman and other car designers would have done.
- There seems to be sculpting of the side of the nose, to promote better laminar flow around the cab. Does this cut turbulence and the energy needed to power the train?
- Bombardier make aircraft and must have some good aerodynamicists and access to wind tunnels big enough for a large scale model of an Aventra cab.
If you get up close to the cab, as I did at Gospel Oak station, it seems to me that Bombardier have taken great care to create a cab, that is a compromise between efficient aerodynamics and good visibility for the driver.
Class 345 Train
These pictures shows the cab of a Class 345 train.
The two Aventras seem to be very similar.
Class 195 And Class 331 Trains
CAF’s Class 195 and Class 331 trains appear to have identical noses.
They seem to be more upright than the Aventras.
Class 755 Train
Class 755 trains are Stadler’s 100 mph bi-mode trains.
It is surprising how they seem to follow similar designs to Bombardier’s Aventras.
- The recessed windscreen.
- The large air intake at the front.
I can’t wait to get a picture of a Class 755 train alongside one of Greater Anglia’s new Class 720 trains, which are Aventras.
Tortillas From Kings Cross Square
If you are arriving at Kings Cross station and feel a little peckish, it is often worthwhile to check out the offerings in Kings Cross Square in front of the station.
I found these delicious gluten-free tortillas last week.
A Quick Pasta Supper For One
A few months ago Marks & Spencer started selling an Italian made gluten-free passta, that is named prosciutto & ricotta cappelletti.
Marks recommend serving it with your favourite sauce or melted butter.
So I used one of my favourite sauces adapted from Serial Cooking – Quick Pasta For One. The idea came from a recipe from Lyndsey Bareham in The Times.
These pictures show the stages.
Note.
- I split frozen peas down into small one-portion pots.
- The yogurt is a small pot of Honey & Ginger West Country Luxury Yoghurt from Marks & Spencer.
- I generally drink Adnams beer!
I shall cook the second half of the pasta in a few days, which will be the fifth time, I’ve had the meal in three weeks.
Does This Bank Launder Money?
I always associate Tide with a brand of washing powder.
So does the bank of the same name launder money?
Travel Industry Confirms Rail ‘Renaissance’ In Europe
The title of this post is the same as that of this article on Railway Gazette.
This is the introductory paragraph.
Assertions that long-distance rail services in Europe are rapidly becoming more popular as passengers eschew flying for environmental reasons were amply confirmed at the Rail Innovation Forum organised by Amadeus at its head office near Nice on October 9-10.
The article also gives these points.
- Swiss Federal Railways are reporting a 26 % year-on-year increase in passengers for the first quarter of 2019 for night trains.
- Sweden is reporting a 12 % increase in rail traffic and a 4 % drop in air traffic.
- Flight bookings across Scandinavia are down by 10 %.
- German long-distance rail travel is rising.
This all seems good news for carbon emissions.
