How To Build A Short Railway Branch Line

This article in Global Rail News is entitled London Overground’s Barking Riverside extension given green light.

The Barking Riverside Extension to the Gospel Oak to Barking Line is a 4.5 km. extension to serve a housing development of 10,800 houses at a derelict site by the Thames in Barking.

The article says this.

The Secretary of State, Chris Grayling, has now given his support to the project – approving the Transport and Works Act Order (TWAO) for the extension.

It puzzles me, why Chris Grayling is in the loop, as the £263million project for the extension is funded by Transport for London, with a £172million contribution from the developers of the houses.

TfL’s contribution works out at just over ten pounds for every man woman and child in Greater London.

By comparison, this article in Rail TRechnology Magazine is entitled MPT wins £350m contract to build Metrolink’s Trafford Park extension. Was a TWAO signed by the Minister for that?

This country is far to centralised!

  1. He is a politician who “has given his support to the project”, not authorised it. He hopes to curry some favour from it.

    Less likely oop north where he has canned just about everything to leave money for HS2 and Crossrail 2 grrrr!

  3. Apparently work on this line commences spring 2018. Supposedly in time for the launch of the electric services. Hmmmm, not holding my breath.

    • I have a feeling they won’t actually electrify the branch. All the documents I’ve seen don’t mention electrification, but they say the line will be run by electric trains.

      As the extension is only three miles long and electric trains need up to 5kWh per carriage per mile, that’s only 120 kWh to go out and back. A Routemaster bus battery is 75 kWh, so one in each car would be more than enough.

      The big problem with overhead electrification in that area is that there are high voltage power cables everywhere and the area has seen some bad thunderstorms.

      Would you want to repair overhead wires in a thunderstorm?

  4. I’ve seen the trams in Bordeaux & Seville that start off under the wires and then run on batteries through the town centres. So, it can work as long as a tram, or train, doesn’t get held up for an extended period and run the batteries down. How does it get rescued if that happens? They must have overhead centenary at the terminal so batteries can be boosted during turn around time.

    • Remember the GOBlin Class 710 trains are dual-voltage, so you could put a short lrngth of third-rail to charge the trains. It would only switch on, when the train is connected and taking electricity. So it wopuld be safe for trespassers.
