As a result, Bombardier Transportation, who recently upgraded the signalling on the Madrid Metro, has committed to installing and testing the new signalling system without any need for weekend closures. Moving millions There will still be a need for weekend closures to upgrade track and platforms, however these will not be the full line closures that have been experienced during previous upgrade work on other lines under the Public Private Partnership (PPP). ---/quote--- Shame that the SSR resignalling project had to be reversed out of the blind alley that the PPP had led it up, but hopefully things should now work out for the best. |

Will this increase capacity? i.e increase train frequency? |

I haven't seen the requirements specification, so I have no idea what Bombardier have committed to on trains per hour on each line. Cheers Puffernutter |

In the rush hour the main issue on most lines seems to be long dwell times at platforms in the centre of town causing trains to back up. Unless there are enough trains to hoover up enough people to prevent the usual scrum to get on and off then I suspect all moving block will do is cause even more trains to sit in tunnels going nowhere.

B2003 More trains is what moving block will provide. Preventing passengers trying to jam themselves on an already full train, obstructing the doors and causing excessive dwell times is what causes trains to back up. In a perfect world, if people could be assured, through a consistent period of reliable operation that the next train will turn up in 90 seconds, then maybe they wont cram themselves in the train in the platform. But I suspect that behaviour will take a long time to change. Cheers Puffernutter |

Trains taking 30 mins to go from finsbury to arnos grove (personal experience). It took about a year for the arrogant ****s to realise their mistake so I won't hold my breath for moving block to improve things significantly. All it needs is one train to take longer than it should at a station and the knock on effect will kick off. In a perfect world, if people could be assured, through a consistent period of reliable operation that the next train will turn up in 90 seconds, then maybe they wont cram themselves in the train in the platform. But I suspect that behaviour will take a long time to change. While people don't trust for the next train to actually show up when the board says it will this behaviour will never change. B2003 |

... Will this increase capacity? i.e increase train frequency? The figures in the TfL press release linked earlier combine the capacity increase of the new S stock and the increased train frequencies allowed by the intended signalling improvements. The Met/Circle/H&C/District combined frequency (ie on the top and bottom of the Circle IYSWIM) increases from the current 28 tph to 32 tph. The much discussed change to the Circle line, extending it to Hammersmith, was an early prerequisite for the eventual 2018 set up. An explanation is available on the TfL website he http://www.tfl.gov.uk/assets/downloa...ce-Changes.pdf Paul |
