Asfordby to be used to test air conditioned tube trains
There's a BBC report at
http://news.bbc.co.uk/2/hi/uk_news/england/leicestershire/6466501.stm that the test track at Asfordby will be used to test the next generation of tube trains which will be fitted with air conditioning. Surely using energy to pump heat out of the trains into the tunnels will just increase the temperature there. Has a solution to the problem of cooling the system as a whole been found? I have heard groundwater mentioned as a possible heat sink but building and running a full system would be horribly expensive. -- Goalie of the Century |

Tube stock will only have air-conditioning in the driver's cabs. Trials of groundwater colling are being carried out at Victoria. Peter |

I wonder why Metronet and Tubelines can't club together and have a joint test track instead of two seperate ones at double the cost. Kevin |

I would imagine that by the time Tubelines are introducing new stock they will be able to use the test track too. The vastly greater number of SSL trains being provided by Metronet makes it sensible for them to be running the place. Aren't the Victoria and Bakerloo (both Metronet), due their replacement stock before any of Tubelines? Paul |

You're quite correct about the difficulties of airconditioning the 'tube' trains - unfortunately since TfL collectively decided that they would use 'tube' for their whole system, there seems to be a lack of a short word to define the sub surface railway, which these trains are for. By announcing 'air conditioned tube trains' now they are just leaving themselves open to much criticism when the next generation of real tube trains is bought, for the Victoria line I believe... Must be a slow news day in BBC Leicester though, this was first announced 5 weeks ago: http://www.metronetrail.com/default....=1170757840171 Paul |

Does Tube Lines have a separate test track, apart from the 900m signalling test track within Highgate depot or the fourth track at South Ealing? As (I think) it's using a different signalling system to Metronet, there doesn't seem to be much point in using the same test track. As far as new trains are concerned, I assume it'll be a few years before new Piccadilly Line trains need testing. In contrast, Metronet has all-new fleets coming soon for the Victoria Line and all the subsurface lines -- a very large fleet of getting on for 2000 cars. |

"This House notes that the loss of the facility will mean that new trains will either have to be tested on the already congested rail network or have to enter service without being full tested, therefore putting passenger safety at risk" Whereas there were reports last week, I think, of testing being done in the Czech Republic. -- Roland Perry |

"This House notes that the loss of the facility will mean that new trains will either have to be tested on the already congested rail network or have to enter service without being full tested, therefore putting passenger safety at risk" I hadn't realised that the main-line TOCs (as opposed to London Underground) no longer used Old Dalby, as the report implies by the talk of saving the line from closure by the decision to test LU trains there. I'd assumed that Old Dalby would still be used for testing main line trains - and now, additionally, LU trains. If main-line trains are no longer tested there, then where are they tested? |
