ORR’s Policy On Third Rail DC Electrification Systems

The title of this post is the same as that of a document I downloaded from this page on the Office of Rail and Road web site.

It is one of the most boring legal documents, that I have ever read and I have read a few in my time.

As I read it, effectively it says that new third-rail electrification is banned because of Health and Safety issues, which take precedence.

But only once in the document is new technology mentioned, that might make third-rail safer and that is a reference to the Docklands Light Railway, where the third rail is shielded.

I am an Electrical Engineer and I was designing safety systems for heavy industrial guillotines at fifteen as a vacation job in a non-ferrous metals factory.

One design of an ideal electric railway would have battery-electric trains, that were charged in stations by third-rail. The third-rail would only be energised, when a train was over the top and needed to be charged. In effect the train would act as an all-enclosing guard to the conductor rail.

Electrification Of The West Of England Main Line

The West of England Main Line runs between Basingstoke and Exeter via Salisbury. It is one of the longest, if not the longest main lines in England, that is not electrified.

It would probably need to be electrified with 750 VDC third-rail electrification, as that standard is used between London Waterloo and Basingstoke.

In Solving The Electrification Conundrum, I described a system being developed by Hitachi, that would use battery-electric trains that were charged by short sections of electrified line every fifty miles or so. For reasons of ease of installation and overall costs, these short sections of electrification could be third-rail, that was electrically dead unless a train was connected and needed charging. These electrified sections could also be in stations, where entry on to the railway is a bit more restricted.

Conclusion

The Office of Rail and Road needs to employ a few more engineers with good technical brains, rather than ultra-conservative risk-averse lawyers.

As a sad footnote, I live in East London, where trespassers are regularly electrocuted on the railway. But usually, it is when idiots are travelling on top of container trains  and inadvertently come into contact with the overhead electrification.

Engineers Go Microbial To Store Energy, Sequester CO2

The title of this post, is the same as that of this article on the Cornell Chronicle.

This is the first two paragraphs.

By borrowing nature’s blueprints for photosynthesis, Cornell bioengineers have found a way to efficiently absorb and store large-scale, low-cost renewable energy from the sun – while sequestering atmospheric carbon dioxide to use later as a biofuel.

The key: Let bioengineered microbes do all the work.

This is slave labour, that even the most ardent of Human and Animal Rights activists would approve.

This is technology to watch!
