Super-Efficient Flats Don’t Need Heating Or Air-Con
The title of this post is the same as that of this article on Page 34 of today;s copy of The Times.
These are the first two paragraphs.
In a city of skyscrapers the 26-storey building on a small island next to Manhattan looks unremarkable. Hiding in plain sight, however, is an architectural revolution.
The House, a dormitory for graduate students at Cornell University, is so energy efficient it can eliminate the need for heating and air conditioning. It is the first “passive house” in the US and is providing a stream of data for engineers.
If someone built a passive skyscraper in London, I’d ceretainly go and look.
Barry Station To Go Step-Free
This document on the Government web site is entitled Access for All: 73 Stations Set To Benefit From Additional Funding.
Barry station is on the list.
These pictures show the station and the current bridge,
Note.
- The trains were very crowded.
- The bridge is approaching its rust-by date.
- I think it is true to say, that the station buildings need a thorough refurbishment.
I have been sent a map of the proposed works and facilities for the South Wales Metro. This snippet shows the lines around Barry station.
Note.
- The lines are not planned to be electrified.
- Barry station will get a new PRM-compliant bridge with step-free access between street and train.
- There will be an airport connection at the station.
I would assume that the station buildings will get the much-needed refurbishment.
Services To Barry, Barry Island, Bridgend and Penarth
The South Wales Metro services through Barry will be as follows.
- Services will terminate in the South and West at Barry Island, Bridgend and Penarth
- Services will terminate in the North at Coryton and Rhymney.
- There will be increased train frequencies.
Trains will be tri-mode Stadler Flirts with three or four cars, which will be similar to Greater Anglia’s Class 755 trains.
Judging by yesterday this capacity increase will be welcome.
Installing The Step-Free Access
It would appear there is plenty of space for a step-free footbridge with lifts.
In Winner Announced In The Network Rail Footbridge Design Ideas Competition, I wrote how the competition was won by this bridge.
A bridge like this could be built at the other end of the station.
It would also be able to built it, without disrupting the train services or the passengers.
Once complete, the old bridge could be demolished or left as required.
Electrification West Of Cardiff Central Station
These pictures show erected gantries for the electrification to the West of Cardiff Central station.
I have been sent a map of the proposed works and facilities for the South Wales Metro. This snippet shows the lines to the West of Cardiff Central station.
Note.
- Electrified lines are shown in blue and unelectrified ones in black.
- The South Wales Main Line is shown as a feint line going East-West to the North of Ninian Park station.
- Trains for Barry Island, Bridgend, Cardiff Airport, Maesteg and Penarth go via Grangetown station.
- Tram-trains for Radyr will go via Ninian Park station.
It looks like tram-trains emerging out of Canton Depot will have immediate access to 25 KVAC overhead electrification.
Treforest Station To Go Step-Free
This document on the Government web site is entitled Access for All: 73 Stations Set To Benefit From Additional Funding.
Treforest station is on the list.
These pictures show the station and the current bridge,
The bridge is not the easiest to cross and I tripped.
I wouldn’t like to cross it in the worst weather the Valleys could through at it!
Installing The Step-Free Access
This Google Map shows the station.
In Winner Announced In The Network Rail Footbridge Design Ideas Competition, I wrote how the competition was won by this bridge.
I believe that one of these bridges could be built at the Northern end of the station.
- The Southbound platform could be widened if necessary.
- The Western end of the bridge might mean a few car-parking spaces would be lost.
- Disabled car-parking spaces could be close to the bridge.
- The bridge could be used to support the electrification in the station.
But most importantly, the bridge could be installed without any disruption to trains and passengers.
I have been sent a map of the proposed works and facilities for the South Wales Metro. This snippet shows Treforest station.
Note.
- Treforest station is shown with a PRM-compliant bridge and step-free access from street to train. The new bridge would deliver this.
- The station is shown electrified.
- A short section of line North of the station is without electrification.
This Google Map shows the area to the North of the station.
It would appear, that instead of rebuilding the bridge to squeeze the wires underneath, a short earthed section of overhead conductor rail would be used.
Conclusion
Using one of Network Rail’s new bridges at Treforest station, solves all the problems of the station and could even make the electrification easier.
Is Taff’s Well Station Planned To Go Step-Free?
This document on the Government web site is entitled Access for All: 73 Stations Set To Benefit From Additional Funding.
Taff’s Well station is not on the list.
These pictures show the station and the current bridge,
Crossing the tracks on the current bridge, is no easier, than at Cathays and Treforest stations, both of which are going step-free.
This map is a schemastic of the South Wales Metro.
Twelve trains per hour (tph) will go through the station, when the South Wales Metro is fully developed.
Passenger numbers for 2017/2017 South between Pontypridd and Cathays are as follows.
- Pontypridd – 864,000 – Step-free
- Treforest – 752,000 – Going step-free by 2024
- Treforest Estate – 84,000
- Taff’s Well – 364,000
- Radyr – 539,000 – Step-free
- Llandaff – 483,000 – Step-free
- Cathays – 946,000 – Going step-free by 2024
Taff’s Well is the second least-used station.
But a doubling of the train frequency in the next few years, will certainly increase passenger numbers.
One guy, I spoke to said, that the station wasn’t busy.
I have been sent a map of the proposed works and facilities for the South Wales Metro. This snippet shows Taff’s Well station.
Note.
- There’s a lot of work to be done in the area.
- Taff’s Well station is shown with a PRM-compliant bridge and step-free access from street to train. The current bridge is not PRM-compliant.
- The station is shown electrified.
- Short sections of line around the station are without electrification.
I feel that to meet their objectives, the bridge needs to be replaced.
Installing Step-Free Access
In Winner Announced In The Network Rail Footbridge Design Ideas Competition, I wrote how the competition was won by this bridge.
I feel that, when Network Rail fully understand their installation procedures and costs, that a bridge like this could be used to replace the current monstrosity.
It also appears that the wires at Taff’s Well station will not be electrified, so could a bridge be used to hold up the overhead wires, that will guide pantographs through the station?
This Google Map shows Taff’s Well station.
The station has the common problem, of those that use the station as a Park-and-Ride have to negotiate the bridge one way.
Does the possibility of coming back from Cardiff, with lots of shopping, encourage shoppers to drive down the valley?
Taff’s Well station illustrates one of the benefits of the winning bridge design.
It could be built at the Northern end of the station, without disrupting the existing trains or their passengers.
I feel that Taff’s Well station would be ideal for one of the new bridges, even if it is not installed for a few years.
Electrification Through Taff’s Well Station
It is planned that electrification will be continuous through the station., which probably means that a new bridge with all the right clearances is desireable.
South of the station, there are a series of modern road bridges, which should have been built to give sufficient clearance for the 25 KVAC overhead electrification.
North of the station, there are two modern footbridges.
This is the one nearest the station.
And this is the more Northerly bridge.
It appears that discontinuous electrification will be used on both bridges to make sure all safety clearances are met.
In an ideal world, the second bridge should surely have lifts!
Conclusion
Obviously, as the plans develop, we’ll know more about what will happen at Taff’s Well station.
Cathays Station To Go Step-Free
This document on the Government web site is entitled Access for All: 73 Stations Set To Benefit From Additional Funding.
Cathays station is on the list.
These pictures show the station and the current bridge,
This Google Map shows the station and its surroundings.
Note.
- As I went through I noticed a lot of development North of the station.
- The map shows developments to the South.
- There appears to be a lot of student accommodation in the area.
All this must add up to a large increase in passenger numbers at the station.
But the biggest driver of passenger numbers, will be the trains through the station, as shown on this map.
Twelve trains per hour (tph) will go through the station, when the South Wales Metro is fully developed.
- South to Barry Island, Bridgend, Cardiff Bay, Cardiff Central, Pearth and Rhoose Airport.
- North to Aberdate, Merthyr Tydfil, Pontypridd and Treherbert.
Cathays station will be busy, with a very busy bridge, handling twice as many trains, as it does now!
I have been sent a map of the proposed works and facilities for the South Wales Metro. This snippet shows Cathays station.
Note.
- Cathays station is shown with a PRM-compliant bridge with step-free access from street to train.
- There is a long and a short break in the electrification to the West of the station.
Cathays station is more complicated than it first appears.
Installing The Step-Free Access
I think that space for a footbridge could be tricky.
The platforms are narrow.
Is there enough space to add lifts to the existing bridge?
It could be difficult to keep the current bridge open, whilst a new one is installed.
In Winner Announced In The Network Rail Footbridge Design Ideas Competition, I wrote how the competition was won by this bridge.
It might be possible to squeeze in an asymmetric version of this bridge. Or one, where the steps went out to the side!
Electrification And Property Development To The West Of Cathays Station
To the West of Cathays station, Corbett Road crosses the railway., as this Google Map shows.
This is probably the shorter break in the electrification.
The second one could be more innovative.
This Google Map shows the railway, as it runs through Cardiff University between Cathays and Llandaf stations.
Note, what looks to be a large development site on the North side of the tracks.
Could it be that the University plans to build over the railway?
It would certainly maximise land use and perhaps make it easier for the University to construct the buildings it needs.
A New Station At Gabalfa
A new Gabalfa station is also proposed between Cathays and Llandaf stations.
Conclusion
It looks like there is a lot happening around Cathays station.

Oxford Splashes Out On £4bn Science Hub
The title of this post is the same as that of this article on page 8 of today’s copy of The Times.
Legal & General is investing the four billion in three related projects.
- Affordable homes for post-gradiates and staff.
- An innovation hub in Begbroke.
- An innovation quarter at Osney Mead.
Oxford is breaking out!
If I have one criticism, it is that Begbroke and Osney Mead appear badly placed for rail and bicycle access.
As some of the best innovators and researchers are short of money, this could be a mistake.
All our universities; large or small, ancient or modern, must come to the aid of the country!
Mountains, Moors And Heaths Offer £20bn In Green Benefits
The title of this post is the same as that of this article on page 2 of today’s copy of The Times.
This is the first paragraph.
Britain’s mountains, moorlands and heaths are worth £20.1 billion for their ability to absorb carbon, remove air pollution and provide recreational activities, according to the Office for National Statistics.
It certainly make you think.
If you think twenty billion pounds is a large number, then this is another two paragraphs.
Natural accounts are required by the European Union but Theresa May has also made them a feature of the 25 Year Environment Plan that she unveiled last year.
The plan is focused on “protecting and enhancing [natural landscapes and habitats] for the next generation”. It follows work by the World Bank, which has estimated the value of the world’s untouched ecosystems at $33.7 trillion (£27.2 trillion).
Surely, this means that if you burn the rain forest, you are literally burning money!
Industry Urged To Decide On Alternative Technology
The title of this post, is the same as that of this article on Rail Magazine.
This is the first paragraph.
The rail industry needs to decide on the right approach to alternative technology as soon as possible, to ensure the industry can continue to reduce emissions.
Speaking to the All-Party Parliamentary Rail Group, Anthony Perratt of the RSSB, outlined how there was a huge opportunity to replace ageing Sprinter trains with new units powered by alternative energy sources like batteries and hydrogen.
The Size Of The Opportunity
Sprinter trains in service of stored in the UK include.
- Class 150 – 135 x two-car, 2 x three-car
- Class 153 – 70 x one-car
- Class 155 – 7 x two-car
- Class 156 – 114 x two-car
- Class 158 – 147 x two-car, 21 x three-car
- Class 159 – 30 x three-car
These add up to 516 trains, with a total of 1035 cars.
In the Wikipedia entry for the Class 710 train, this is said.
TfL announced that it had placed a £260m order for 45 four-car Bombardier Aventra EMUs.
This works out at nearly £1,500,000 for each car of a modern train.
This means that replacement of the Sprinters, with new independently-powered trains, would be project of the order of £1.5billion.
That is a market, that would be very much desired by a train builder.
Battery, Diesel Or Hydrogen Power?
Diesel power is probably not a good idea, if it can be avoided.
The following points about hydrogen- and battery-powered trains should be noted.
- Most hydrogen-powered trains are battery-powered trains, with a hydrogen fuel-cell to recharge the batteries.
- Battery technology is improving fast.
- Systems to rapidly charge batteries will be available in a couple of years.
- Battery-powered trains can use existing electrification to charge the batteries.
- Hydrogen-powered trains may need a large tank for the hydrogen, which limits passenger capacity.
- Hydrogen-powered trains need a refuelling structure, which may be more difficult to install, than a charging system for battery trains.
I feel that innovative engineers will be able to find ways to enable battery-powered trains on routes that need independently powered trains.
Conclusion
I don’t think, that we’ll see many long-term applications of hydrogen-powered trains in the UK.
Warning As Electricity Cables Are Switched On In Manchester
The title of this post is the same as that of this article on Rail Advent.
This is the first paragraph.
Network Rail has warned members of the public to stay off the railway as new high voltage equipment goes live on the line between Stalybridge and Manchester Victoria.
It now looks like electric the current service between Stalybridge and Wigan North Western stations can now be run more efficiently by a Class 769 train, when these enter service.
If Network Rail were to get their skates on and electrify between Bolton and Wigan North Western stations via Lostock Junction, the talybridge and Wigan North Western Route could be run by electric traction.
This electrification of the Lostock Junction route, would also allow the Wigan North Western and Alderley Edge service to be run by electric traction.
Looking at Google Maps of the route, it appears that gantries are being or have been erected.
