Why Do Some Train Operators Still Buy Half-Trains?

This picture shows the unloved-by-SWR Class 707 trains.

South Western Railway‘s predecessor; South West Trains bought thirty of these trains and SWR is replacing them with Class 701 trains.

Sixty of these new trains will be ten-cars in length and thirty will be five-car.

Why?

Consider.

  • Most Class 707 trains, always seem to run as ten-car units, formed of two trains.
  • There are four cabs, rather than two.
  • A ten-car Class 701 train has twenty more seats than two five-car trains.
  • Including standing passengers, a ten-car Class 701 train has eight percent more capacity, than two five-car units.
  • Staff have to get out of the train and back in, to go between the front and back of the train.
  • I’ve even seen trains delayed because the conductor was helping a disabled passenger in the other train.

Running two half-trains as a full-size train must surely be more stressful for the staff and more uneconomic for train operators.

The only place for five-car trains, is surely on routes with short platforms.

The Cut-And-Paste Aventra

It should also be noted that Bombardier’s new Aventras and other recently-designed trains, can be cut and pasted to adjust the trains that an operator needs.

At the present time, services on the Gospel Oak to Barking Line, which can only accept four-car trains are being run by four-car Class 378 trains, which have been shortened from their normal five-car length by removing a car.

So for instance if on a route, South Western Railway needed to run eight-car trains due to a temporary length restriction, they could shuffle a ten-car and a five-car train to get an eight-car and a seven-car,

In a list of Aventra variants, the following are detailed.

Tfl Rail

Class 345 trains will be nine-car, but currently they are running as seven-cars.

London Overground

Class 710 trains will be used in three ways.

It has puzzled me, why the Lea Valley sets are not to be built as eight-car trains and I discuss this in Latest On The New London Overground Class 710 Trains.

Greater Anglia

Class 720 trains will be `22 ten-car and 89 five-car trains.

I think that Greater Anglia have some routes, that cannot accept ten-car trains.

As I showed for Hertford East station in Could London Overground Extend To Hertford East Station?

So will we be seeing some creative shuffling to get a tailored fleet, with perhaps some eight-car trains for routes like those to Hertford East?

I think that six ten-car trains and four five-car trains can be converted into ten eight-car trains.

South Western Railway

Class 701 trains will be 60 ten-car trains and 30 five-car trains.

Do South Western Railway need a sub-fleet of eight-car trains?

They can easily create one, by shuffling the trains.

West Midlands Trains

Class 730 trains will be 36 three-car trains and 45 five-car trains.

These are like-for-like replacements of the current fleet.

c2c

Class 711 trains will be six ten-car trains.

They will be replacing Class 387 trains on a short-term lease.

Conclusion

It appears to me, that for the train operator to have maximum flexibility, that you need to start with a long train and a short train and be able to shuffle cars around to get the train fleet you need.

Certainly a fleet of both ten-car and five-car Aventras gives you the possibility of creating a sub-fleet of eight-car trains.

Interestingly, the Hitachi Class 800 trains appear to have a similar ability.

Are Class 378 Trains Better For Canoodling?

A couple, who were probably married or in a long term relationship, judging by their body language were at it yesterday.

She was sitting on the perch seat by the door.

He was standing in front, facing her, whispering sweet nothings or his supper preferences in her ear, as the train with standing room only trundled towards Whitechapel.

You see this type of behaviour regularly.

Was encouraging it a design objective?

Is Cambridge Going To Save The World From Global Warming?

Watch this video!

And then visit Superdielectrics web site.

It does appear to be a  bunch of mad scientists in Cambridge, who’ve come up with the bizarre idea of using the material in soft contact lenses as an energy storage medium.

Link Up With Rolls-Royce

And then there’s this press release on the Rolls-Royce-Royce web site, which is entitled Rolls-Royce Links Up With UK-based Superdielectrics To Explore Potential Of Very High Energy Storage Technology.

Conclusion

I have been observing technology since the 1960s.

This is either one of those scientific curiosities , like cold fusion, that appear from time-to-time and then disappear into the scientific archives or a game-changer

I suspect we’ll know in a couple of years.

But even if it is isn’t the solution to affordable and massive energy storage,, that will save the world, I believe that one of the teams of men and women in white coats, somewhere in the world will crack the problem.

A Residential Development Convenient For Rugby And Train Travel

I went through Twickenham station yesterday and took these pictures.

Surely many more stations could sustain a substantial development of much-needed housing on the top.

The Problem Of Step-Free Access At South Acton Station

South Acton station would be one of two stations on the shared section of the North London Line and the proposed West London Orbital Railway.

It could be handling fourteen passenger trains per hour in both directions.

This Google Map shows the station.

Note how all the land close to the line has been sold to developers and new housing, now means space is very restricted.

This image shows a close-up of the bridge.

With a train stopping at the station every four minutes, a step-free means of crossing the line is essential.

The often-used solution of building a new step-free bridge and keeping the old one is not a solution at South Acton station, due to the space restrictions.

I suspect the current bridge could be replaced with a step-free one, but how do you provide a bridge whilst the new one is installed?

I went back to the station on May the 2nd and took these pictures.

It might just be possible to squeeze a bridge in at the North end of the station.

There is certainly enough space for a bridge tower on the Western side behind the fence and if space can be found on the other, a bridge might be possible.
