The Anonymous Widower

An Addenbrooke’s Train Station Has Got The Thumbs-Up From The Transport Secretary

The title of this post is the same as that of an article in the Cambridge News.

These are my thoughts.

Location

Cambridge South station, if they follow the convention of the name of the newly-opened Cambridge North station, has the ideal location.

  • It is South of the City of Cambridge in a similar position to how Cambridge North station is North of the City.
  • The Cambridgeshire Guided Busway could be diverted to serve the station.
  • Addenbrooke’s Hospital and the Cambridge Biomedical Campus could be a short walk or a travelator ride away.
  • Addenbrooke’s bus station could be moved to be adjacent to the new train station.
  • Services between both Liverpool Street and Kings Cross stations and Cambridge would call.
  • There is space for a large car park for both train passengers and hospital patients and visitors.
  • In the future, trains on the East West Rail Link will be able to call.

The location would also allow trains or guided buses on a reopened Stour Valley Railway to call.

Trains

When Thameslink opens fully, it looks like the trains going through Cambridge South station could include.

  • 1 tph – CrossCountry – Birmingham New Street to Stansted Airport.
  • 1 tph – Greater Anglia – Norwich to Stansted Airport.
  • 2 tph – Greater Anglia – Liverpool Street to Cambridge/Cambridge North/Ely
  • 3 tph – Great Northern – Kings Cross to Cambridge/Cambridge North
  • 1 tph – Great Northern – Kings Cross to Kings Lynn
  • 2 tph – Thameslink – Brighton to Cambridge/Caambridge North
  • 2 tph – Thameslink – Maidstone East to Cambridge/Caambridge North

Note tph is trains per hour.

This totals to twelve tph. And that’s only for starters.

  • The East West Rail Link will surely add 2 tph to Oxford.
  • All these services to Kings Cross and St. Pancras must surely hit Greater Anglia’s Liverpool Street services. Will this mean they use some of their massive fleet of new trains to provide extra services to Liverpool Street and Stansted.

It should also be noted that Greater Anglia serves the City, Stratford and connects to Crossrail, whereas Great Northern doesn’t!

The Stour Valley Railway

If Cambridge continues to be one of the most successful cities in the world, I can’t believe that the Stour Valley Railway won’t be reinstated as another route across East Anglia.

I discuss this proposal in detail in An Affordable Reinstatement Of The Stour Valley Railway.

I came to this conclusion.

Reinstatement of the Stour Valley Railway  would be the ultimate modern railway for one of the world’s most high-tech cities.

I think it will be built at some time.

Cost

The usual suspects will complain about Cambridge South station being another station in a city near London, that already has two stations.

This is said about the cost of Cambridge North station in Wikipedia.

On 19 August 2015, Cambridge City Council approved Network Rail’s new plans for the station, which were not substantially different from the original plans put forward by Cambridgeshire County Council in 2013. Following Network Rail’s intervention, the cost of the station was revised upwards to £44 million.

When first proposed by Cambridgeshire County Council in around 2007, at the cost was £15 million, with a benefit-cost ratio of 3.09.

So much for Network Rail’s costing systems.

Incidentally, Kirkstall |Forge station in Leeds, which is a two-platform station on an electrified line with full step-free access cost £16 million. So as Cambridge South will probably have an extra platform and lots of parking, I would reckon £25 million would cover the cost of building the station.

To put this sum in context, two Cambridge companies have recently been sold.

These two deals must have generated a lot of tax revenue.

Conclusion

A start on Cambridge South station should be made next week.

Saving Fuel In Rail Vehicles

The title of this post is the same as this page on the web site of a company called Artemis Intelligent Power.

The first paragraph sums up the project and the participants.

Since 2013, Artemis has been proud to work with leading companies Ricardo and Bombardier on the project ‘Digital Displacement® Rail Transmission with Flywheel Energy Storage’ which has been supported by the government funding body Innovate UK.

So who are the players, mentioned in this paragraph.

  • Artemis Intelligent Power, is a company that has been spun out of Edinburgh University, that is now owned by Mitsubishi Heavy Industries. In 2015, the company won a MacRobert Award, which is regarded as the leading prize recognising UK innovation in engineering.
  • Ricardo is one of those companies, that have shaped our lives, but few people have ever heard of. At some time most of us would have driven a diesel car, where the engine has been designed around patents or ideas from Ricardo.
  • Bombardier in the UK are best known for the trains they build in Derby.
  • Innovate UK is the UK Government’s innovation agency.

I think it is true to say, that these players wouldn’t be short of ideas, engineering knowledge and resources, including money.

This second paragraph, describes in simple details, what they aim to achieve.

The system is based on the use of Artemis Digital Displacement® pump-motors to capture braking energy from diesel multiple unit (DMU) rail cars, store it in high tech Ricardo flywheels and then use it to displace diesel fuel during vehicle acceleration. Such energy recovery is commonplace on modern electric trains but there is general agreement in the rail industry that are many routes where electrification is unlikely ever to make economic sense.

There is also a press release from Ricardo, which has this title Significant fuel savings and rapid payback shown for rail flywheel hybrid technology.

The project has a name of DDFlyTrain and searching for this word, found this article in the Railway Gazette, which gives more details. These are the last two paragraphs of the article.

The delivery of the flywheel will now enable the assembly of a test rig for laboratory verification trials. Ricardo said its latest flywheel represents a significant advance on products available two years ago, drawing on research undertaken for Formula 1 cars. The flywheel spins in a permanent vacuum to reduce energy losses, with transmission by a magnetic gear system which does not require rotating seals or vacuum pumps The flywheel will be mated with Artemis’ Digital Displacement hydraulic transmission technology, which combines mechanical electric and software elements to facilitate efficient operation despite the varying speeds and loadings of a rail environment.

There are currently no firm plans for installation on a real trainset, but this could be undertaken in the future following laboratory tests.

I shall be searching for DDFlyTrain.

Conclusion

Artemis Intelligent Power and Ricardo have developed some very advanced technology.

The News page on the Artemis IP web site, details some varied applications for their technology in the fields of wave power, excavators, diesel railcar transmissions and wind power.

Ricardo’s flywheel has the name of TorqStor and looks to have potential in other applications.

Could we be seeing a larger version of Torqstor in Electrical Multiple Units, like the new Aventra?

With technology companies like Ricardo and Artemis IP, you never know what is possible, until it has been done!
