Innovative Composite Masts Look To Reduce Cost And Increase Efficiency Of Rail Electrification
The title of this post is the same as that of this article on New Civil Engineer.
This is the sub-title.
Engineering consultancy Furrer+Frey will this week unveil its innovative composite masts for rail electrification, which could revolutionise the way that rail electrification is undertaken.
Other points from the article include.
- Development has been undertaken with Cranfield, Southampton and Newcastle Universities and Prodrive and TruckTrain.
- The project was part funded by the Department for Transport and Innovate UK through the First Of A Kind competition.
- The first composite masts have been created and tested at St Bride’s feeder station, just outside Newport in Wales.
This Google Map shows the area, where the test will take place.
Note.
- The South Wales Main Line crossing the South-East corner of the map.
- Newport station is to the East and Cardiff station is to the West.
- The St. Brides feeder station alongside the railway, by the Green Lane bridge.
I would assume that the connection to the National Grid is via the St. Brides 25 kV Substation in the North-West corner of the map.
The article lists the features of the design.
- A typical steel mast weighs 750 Kg., whereas a composite mast weight just 80 Kg.
- I suspect that these masts can be lifted around by a couple of average workers.
- They have lower wind resistance.
- Piles can be less deep. The prototype piles are 1.25 m., as against many that are over four metres on recent schemes.
- The piles have sensors to detect, when they are out of kilter and need replacing.
- Currently, wonky masts need to be identified by hands-on measurement or observant drivers.
- Two masts have been tested to destruction, to see if they match the theory.
But this to me as an Electrical Engineer is the clincher.
Furrer+Frey GB head of UK projects Noel Dolphin says this about the new design.
When they do take it to a mass manufacturing stage, it will be without carbon fibre inside, which presents another opportunity. The other ultimate goal is that the structure is insulating in itself. It’s another big saving if you can remove the insulators on the electrification cantilevers, as they’re expensive in themselves.
It’s all going the way of much more affordable electrification.
I have a few further thoughts.
The Involvement Of Prodrive
Prodrive are best known for their involvement in motorsport, as the home page of their web site indicates.
But as their site also indicates they get involved in other forms of high-performance disruptive engineering, where their experience is relevant.
Prodrive build the prototypes, but won’t build the production masts, although I suspect, their expertise will be used.
The TruckTrain
TruckTrain is a concept with roots in Coventry University that could be off-beam enough to be the new normal.
I have updated my thoughts on the TruckTrain and it is now in a post called The TruckTrain.
My Conclusion About TruckTrains
I like the concept and I can’t see why it would not be successful worldwide.
The Involvement Of TruckTrain With Furrer+Frey
This puzzled me for a time, as undoubtedly, the TruckTrain will be able to use standard electrification.
But in the TruckTrain leaflet, they mention that the TruckTrain has been designed to use single-track short-terminals.
So did they approach Furrer+Frey to find out about electrifying short terminals and the Swiss company felt TruckTrain was a concept they could support?
Obviously, if the TruckTrain is developed to be a battery-electric train, some mini freight terminals will need the ability to charge the TruckTrain.
Could A TruckTrain Be Used to Support Electrification?
Would a TruckTrain be the ideal support vehicle to erect or repair electrification?
If you take the problem, when the wires have been damaged, a TruckTrain could get to the site at 100 mph, much faster than a truck on the road. It could also have a platform to lift the engineers for inspection and repair.
A TruckTrain could be more than just a transport system.
Conclusion
Furrer + Frey’s lightweight composite electrification masts are a good idea.
Teamed with TruckTrains, they could prove a very powerful freight concept, where new mini freight terminals are needed.
Cardiff Bridge Avoids £40m Demolition Thanks To Electric Resistant Paint
When I first saw this headline on this press release on the Network Rail web site, I felt it sounded too good to be true.
This is the introductory paragraph.
In a world first, electric resistant paint combined with voltage-controlled clearance (VCC) has helped make a Victorian railway bridge usable by new electric trains, avoiding weeks of passenger disruption and train delays in the process.
I think this is the bridge.
Note.
- The South Wales Main Line runs East-West, with Cardiff Central station to the West.
- The track between Cardiff Queen Street and Cardiff Bay stations runs North-South, with Cardiff Queen Street station to the North.
- The two rail lines cross over a canal.
- The site is surrounded by new high-rise buildings.
- The clearance been the bridge and the main line underneath appeared to be too tight for electrification to be fitted.
But by using the combination of technologies, as stated in the introductory paragraph, Network Rail were able to squeeze the wires through, which didn’t need the bridge to be demolished and rebuilt on a tricky site.
I can see that railways and other places, where high-voltage cables are close to metal structures, will be able to find lots of uses for Southampton University’s “Magic Paint”
Delivery Drone Flies Medical Supplies To Britain’s Isle of Wight
The title of this post, is the same as that of this article on Reuters.
This is the introductory paragraph.
A new drone service will reduce delivery times for urgent medical supplies to a hospital on the Isle of Wight, which lies about 8 kilometres off the south coast of England.
In some ways the most remarkable thing about this project, was that the drone was developed by Southampton University to deliver medical supplies in remote parts of Africa.
- It is twin-engined.
- It has a range of 100 km.
- It can carry a 100 kg payload.
- It can take off and land on short grass runways.
More details can be found on this page of the Southampton University web site.
This is a video of the first delivery.
