Ruislip Station – 16th July 2023
In TfL Announces The Next Tube Stations To Be Prioritised For Step-Free Access To Meet The Mayor’s Bold Accessibility Targets, it stated that Ruislip station will be made step-free.
So I went to have a look and took these pictures.
Note.
- The station is used by Piccadilly and Metropolitan Line trains, which are different sizes.
- There appears to be a well-preserved signal-box at the Eastern end of the station.
- The Eastbound platform has step-free access from the street.
- Crossing the tracks is by a Victorian steel footbridge.
- The station is Grade II Listed.
- The listing includes the the signal box and the footbridge.
This 3D Google Map shows the station.
Note.
- The footbridge in the South-West corner of the map.
- There is not much space to put a second bridge across the tracks.
- It might be possible to build a step-free footbridge with lifts by the road bridge.
If English Heritage and the Heritage Taliban dig in their heels, this could be a difficult station to make step-free.
But the London Underground has several bridges of this type, so perhaps this one is being scheduled early to test the reaction.
This second Google Map shows the road bridge and the Western ends of the platforms to an enlarged scale.
This picture shows the station side of the road bridge.
There could be space to put a steel bridge with two lifts by the road bridge.
Coupled with a comprehensive restoration of the current footbridge and a repainting of the road bridge, this could satisfy all parties.

Would A Dual-Fuel Boeing 747 Or Airbus A380 Save Carbon?
This press release from Airbus is entitled The ZEROe Demonstrator Has Arrived.
This is the introductory paragraph.
2022 marks a new and exciting phase for ZEROe – Airbus’ ambition to develop the world’s first zero-emission commercial aircraft by 2035. The multi-year demonstrator programme has officially been launched with the objective to test a variety of hydrogen technologies both on the ground and in the air.
The ZEROe demonstrator will be the first Airbus A 380 aircraft and it is shown in this Airbus visualisation.
Note.
- The four hydrogen tanks in the fuselage.
- The fifth engine mounted in a pod on the fuselage.
- There’s certainly lots of space inside the fuselage for more hydrogen tanks and test and monitoring equipment.
Take away the fifth engine and the test equipment and this aircraft becomes an A380 with two fuel systems; hydrogen and aviation fuel.
Consider.
- Suppose two engines were hydrogen-capable and two were normal engines running on aviation fuel or Sustainable Aviation Fuel (SAF).
- I don’t think it is impossible to build engines that could run on both hydrogen and Sustainable Aviation Fuel.
- All aircraft use fuel at a higher rate, during take-off and climbing.
- Do long non-stop flights use less fuel, than ones with stops?
- As altitude increases, air resistance decreases.
- Aircraft could fly slower to reduce the fuel needed, as they did in the oil crises in the last century.
- Generally, the most economical way to fly a route, is to climb to maximum altitude, fly level until descending into the destination.
- The aircraft would not carry cargo in the belly-hold.
- There could be a hydrogen-powered APU, as I wrote about in Airbus To Trial In-flight Auxiliary Power Entirely Generated By Hydrogen.
- This document from IATA says that in its liquid form, contains about 2.5 times more energy per kilogram than kerosene.
- The Boeing 747 first flew in 1969 and the Airbus A 380 in 2005, so these aircraft are well known.
I just wonder, if it is possible to work out a flight profile, that would enable these aircraft to fly very long non-stop routes?
- All four engines would be used for take-off.
- An appropriate power setting would be used for the cruise and the descent.
- There would be large numbers of 747s and A 380s in good condition to convert.
- The plane would land with little or no hydrogen left.
The hydrogen used would cut the carbon footprint of the flight.
Italian Firm To Build Green Hydrogen Platform For CrossWind’s Hollandse Kust Noord
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
CrossWind has awarded Rosetti Marino an Engineering, Procurement, Construction, and Installation and Commissioning (EPCIC) contract for an offshore green hydrogen production and storage plant, located within CrossWind’s Hollandse Kust Noord offshore wind farm in the Netherlands.
These paragraphs describe the platform.
Rosetti Marino said that the pilot plant, called the Baseload Power Hub and fully integrated into an offshore wind farm, is a world first.
The plant on a MegaWatt scale will convert excess wind energy to green hydrogen through an electrolyser and store it as green hydrogen that can be converted to electricity when needed via a fuel cell.
It will also include battery storage for shorter-term power storage.
It looks like they’ve got all angles covered.
I suspect that we’ll see more platforms like this, as they should make the output of a wind farm much more controllable.
Ørsted Receives Development Consent For 2.6 GW Hornsea Four Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The UK Secretary of State for Energy Security and Net Zero has granted development consent to Hornsea Project Four, a 2.6 GW offshore wind farm Ørsted plans to build some 69 kilometres off the Yorkshire Coast.
This is the first paragraph.
The UK government, in a press release issued on 12 July, stated that Hornsea Four was the 126th Nationally Significant Infrastructure Project and 73rd energy application to have been examined by The Planning Inspectorate within the timescales laid down in the Planning Act 2008.
It certainly looks like The Planning Inspectorate has been working overtime.
Note that the four Hornsea wind farms are planned to have at least the following sizes.
- Hornsea 1 – 1218 MW
- Hornsea 2 – 1386 MW
- Hornsea 3 – 2852 MW
- Hornsea 4 – 2600 MW
These four wind farms give the Hornsea complex, a total capacity of at least 8056 MW.
When I worked at ICI in Runcorn in the late 1960s, I used to cross the Runcorn Bridge twice every day and would see Fiddlers Ferry power station, with its eight cooling towers, on the North Bank of the River Mersey to the East. It was generally thought of as a large coal-fired power station.
These pictures of Fiddlers Ferry power station were taken in 2021, from a Liverpool-bound train on the railway bridge.
This Google Map shows the power station.
Note.
- Fiddlers Ferry may have been large for its time at 1989 MW, but it is still less than a quarter of the size of the Hornsea wind farm!
- Drax power station in 1986 at 3960 MW, was larger than Fiddlers Ferry, but was still less than half of the size of Hornsea!
Hornsea wind farm is a true green giant!
This paragraph is from the Hornsea Project 4 section of the Wikipedia entry for the Hornsea wind farms.
Construction of the wind farm was provisionally expected to start in 2023, and be operational by 2027, at the earliest. The project’s capacity is unknown by Ørsted due to the ever increasing size of available wind turbines for the project.
When completed, it could be even bigger.
Bradford Railway Station: Axed Plans For New Travel Hub Reconsidered
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Plans for a new railway station in Bradford will be reconsidered after the government previously scrapped them.
These paragraphs outline how the government has changed its mind.
Former Transport Secretary Grant Shapps cancelled the plan for Northern Powerhouse Rail (NPR), a brand new line serving the city, in November 2021.
The government has said an updated business case for the project was expected later this year.
West Yorkshire Mayor Tracy Brabin welcomed the news but criticised the “dither and delay”.
When the Integrated Rail Plan (IRP) was unveiled in 2021, it included cutting much of HS2’s eastern leg and scaling back NPR, including plans for a new station and line in Bradford.
The announcement that the government would now reconsider plans was made in the Department for Transport’s (DfT) response to the Transport Select Committee’s report on the IRP.
The committee had argued that the department had not properly tested alternative options to its proposals and had left out analysis of wider economic “levelling up” impacts of different options for NPR.
But there are no details yet.
Do We Know Anything?
The new station has been proposed to be built on the site of the current St. James Wholesale Market In Bradford.
This OpenRailwayMap shows the route of the railway between Leeds and Bradford Interchange stations, which runs via New Pudsey station.
Note.
- Leeds is to the East.
- Bradford Interchange station is in the North-West corner of the map.
- The yellow line across the map is the railway between Leeds and Bradford Interchange stations.
- St. James Wholesale Market is the rectangular building towards the top of the map in the middle.
- The dotted line going through the market is a disused goods line.
It is not obvious how the station will be connected to the rail network.
What’s Gone Wrong With Taskrabbit?
I’ve used Taskrabbit several times in the past and as I have a few electrical problems, I thought I’d see if they could help me.
The major problem, I have is a broken smoke detector, that won’t stop bleeping. As it is in my bedroom, I’m not getting a good night’s sleep.
This would be the sort of problem, I’d have fixed myself in the past, but as it’s above my bed, I don’t think I trust my balance to fix it, after my stroke.
I could always borrow a shot-gun and fix it for ever.
My trouble with Taskrabbit is that it doesn’t recognise my address and says it is out of their coverage area.
I have sent a message to Taskrabbit and they say to ring a US number, if they haven’t got back to me in two days.
That limit expired four hours ago.
It’s the worst customer service I’ve found in years.
£20 Per Hour Is A 43 % Pay Increase Over £14 Per Hour
The BBC has just reported on the Junior Doctors Strike from outside University College Hospital.
- Banners were showing that their current pay rate is £14 per hour.
- In an interview, a strike leader said that junior doctors need an offer of £20 per hour.
That would be a pay increase of forty-three percent.
I’m sure we’d all like a pay or pension increase of that amount.
Germany Rakes In EUR 12.6 Billion Through ‘Dynamic Bidding’ Offshore Wind Auction
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Germany’s first dynamic bidding process, covering four offshore wind zones with a combined capacity of 7 GW, has generated EUR 12.6 billion in proceeds, according to the Federal Network Agency.
This dynamic bidding process seems to have brought in the euros.
I hope the Crown Estate is going to look at this bidding, to see if it would be good for the UK.
Silvertown Tunnel: Cracks In Mayoral Policies
The title of this post, is the same as that, as this article on the BBC.
This is the sub-heading.
It is an infrastructure project that is well-underway with the boring almost completed — but it has a very low profile.
These three paragraphs possibly explain why.
Every step of the Crossrail tunnelling, the media were invited along. Not so with this project.
This is Silvertown Tunnel. It is more than 1km long and will be London’s first road tunnel in over 30 years.
Perhaps one of the reasons it isn’t being pushed publicity-wise, is it is very controversial.
Reading the rest of the article it certainly is controversial in many people’s minds.
These are my thoughts.
Avoiding The Dartford Crossing
When I drove back to Suffolk from Gatwick, Kent or Sussex, in the last century, because of congestion at the Dartford Crossing, I would sometimes cut through London and use the Blackwall Tunnel, when I thought it would be quicker.
When the Silvertown Tunnel opens, this could be a viable alternative for vehicles.
My experience of modelling flows, tells me, that water finds its own level. With driving, Satellite Navigation will be able to tell drivers, which will be the fastest route.
It is my view, that the Silvertown Tunnel will become the biggest rat-run in London.
Except some of these rats will be super-rats in 45-tonne HGVs.
Cutting Pollution In London
If super-rat-running is going to happen, then this will raise pollution in Central London, with all those heavy trucks going through.
The only way to cut pollution would be to have differential pricing for vehicles in the tunnels.
Perhaps hydrogen and electric vehicles should be at a discount.
But then Sadiq Khan doesn’t have a hydrogen policy, except to ignore it and hope it goes away.
The Elizabeth Line Effect
Talking to Elizabeth Line staff at Whitechapel station, they feel that there is an increasing number of passengers, who do journeys in East London on an up-one-branch-down-t’other basis between places like Ilford and Woolwich.
I believe, that other cross-river railways and the Bank station improvements, will also take passengers out of their cars, which will free up the Silvertown Tunnel for more HGVs.
A City Airport Station On The Elizabeth Line
I wrote about this in Thoughts On London City Airport And The Elizabeth Line.
How many cars would this remove from the tunnels under the Thaames?
