The Anonymous Widower

Thoughts On Highspeed to Hastings

Since I wrote Kent On The Cusp Of Change – Highspeed To Hastings, a couple of months ago, several things have happened.

And Now There Are Three!

Trenitalia has pulled out of bidding for the new Southeastern franchise as reported in this article in the International Rail Journal.

This leaves just three bidders.

  • A joint venture of Abellio, East Japan Railway Company and Mitsui
  • Govia
  • Stagecoach

The same joint venture were recently awarded the West Midlands franchise.

The new franchise will be awarded in August 2018, with services starting in December 2018.

Electrification Has Been Abandoned

Major electrification schemes have been abandoned, so I suspect it will be even more unlikely that Ashford to Hastings will be electrified.

The Aventras Are Coming

Class 345 trains have started to appear on Crossrail and it is my opinion that they are a fine train.

In An Exciting New Aventra, I laid out the philosophy of the new trains and in How Long Will It Take Bombardier To Fulfil Their Aventra Orders?, I discussed how Bombardier will build the trains, at a rate of twenty-five carriages a month.

The rate comes from this article in The Guardian, which is entitled Full speed ahead for train builders as minister pulls plug on electrification, where I found this useful nugget of information, from the General Manager of Bombardier’s Derby plant.

Building trains in an “ergonomically correct” fashion, he says, means completing and testing the carriage’s constituent parts, then assembling them, rather than wiring them up afterwards – and also takes the risk away from a production line which boasts a rate of 25 carriages per week.

It sounds like Bombardier’s engineers have been drinking and swapping ideas, with Toyota’s production engineers a few miles down the road at Burnaston.

The New South Eastern Franchise

So do we have any clues as to what the new South Eastern franchise will be doing?

South Western Railway

South Western Railway‘s routes have a similar pattern to those of the South Eastern franchise, with an intense suburban network and longer distance services.

You could also argue that Greater Anglia isn’t much different.

Both these other franchises have are replacing their suburban trains with new 100 mph trains with all the trimming like wi-fi and toilets.

Both have chosen a mix of five and ten-car Aventras.

This would appear to give the following advantages.

  • The 100 mph trains with excellent acceleration and smooth regenerative braking help to make services faster and more frequent.
  • A near identical fleet will help maintenance and crew training.
  • It is easier to get the train-platform interface better, if only one class of train calls at a station.
  • Platform compatibility with Crossrail and Crossrail 2.

I suspect that the new South Eastern franchise will think on similar lines.

The Networkers Must Be Going

Southeastern currently has a total of 674 Networker carriages, most of which will surely be moved on by the new franchise holder.

I believe that these trains with their 75 mph speed and average performance, is not high enough for efficient timetabling of services and that consequently the new franchise holder will probably replace these trains with 100 mph units.

One choice would be to use a mix of new five and ten-car Aventras as chosen by Greater Anglia and South Western Railway. Replacing Networker carriages with the same number of Aventra carriages would take around six months of production at Bombardier.

The Aventras must be high on the list of new trains, as some of the new trains, may have to use the same platforms as Crossrail, if the line is extended from Abbey Wood station.

The Extra High Speed Trains

To serve Hastings and increase the number of Highspeed services, the new franchise holder, will have to obtain some more trains that can use High Speed 1.

Some of these trains will need the ability to travel on the Marshlink Line between Ashford and Hastings.

Consider.

  • It probably wouldn’t be a good idea to have two different types of trains working to Ashford on High Speed 1.
  • Class 800 trains, which are closely related to the Class 395 trains have onboard diesel power and might have energy storage to handle regenerative braking.
  • Class 395 trains are getting towards ten years old and are approaching the need for a refresh.
  • Hitachi have built trains with onboard energy storage in Japan.
  • Diesel fuel might not be allowed in the tunnels of High Speed 1.
  • Hitachi would probably be very disappointed to not get this order.

More Class 395 trains fitted with either onboard energy storage must be the favourite.

Conclusion

Kent will get Aventras to improve suburban services and more Class 395 trains with batteries for Highspeed services.
