"The Battersea Branch will be the first extension to the Underground network since the Jubilee Line Extension from Green Park to Stratford" Since https://en.wikipedia.org/wiki/List_o...round_stations is sortable by opening date, forgetting https://en.wikipedia.org/wiki/Heathr...inal_5_station is a major facepalm. -- Basil Jet recently enjoyed listening to 1993 - The Stinking Rose - Kev Hopper |

You're quite right, of course, but I suppose they don't regard the additional Heathrow station as an extension. |

You're quite right, of course, but I suppose they don't regard the additional Heathrow station as an extension. It's approx 2km, so rather more than just a new station. Topographically it's almost identical to the Battersea Branch (~3.5km) but maybe the writer thought it was like T4? -- Roland Perry |

I suspect they just didn't think about it. |

Those almost straight new tunnels are among the loudest on the whole LU network. It's almost painful. Does anyone know why? |

If you mean the T5 tunnel, I imagine they're the only part of the tube constructed with NATM. -- Basil Jet recently enjoyed listening to 2001 - Out Of The Races And Onto The Tracks - The Rapture |

Parts of the central HEx station famously use NATM, but I don't think any of the Tube or HEx running tunnels used NATM. They look like normal deep bored tube concrete ring tunnels, as used on the JLE and probably the Battersea extension. Those T5 tunnels are fairly shallow and have heavy airliners parked or taxiing above, so I wonder if they use a more sturdy construction than usual tube tunnels? |
