Hi all,
There's a London-oriented email newsletter thing called London by London; it's like Notes & Queries in structure, with people asking questions and other people answering them. This one doesn't have an answer yet, so i thought i'd pass it on: "Your post reminded me to ask the LBL readership (is it really 10,000 strong?) if anyone has heard another noise made by jubilee line trains. I can only describe the noise as the sound of running water. It's as if you're the other side of a very thin wall and someone's just flushed the loo in the next room. The noise seems to travel from one end of the carriage to the other and yet no one on the carriage bats an eyelid at this seemingly (super-) natural sound. Has anyone else heard it and do they know what it is?" Any suggestions? This follows a question about the 'gear-changing noise' that comes from the thyristors. tom -- I am become Life, destroyer of worlds |

Anything else that can produce a kind of white noise sound really ![]() B2003 |

The only thing I can think of from my days of driving those trains is the noise made by the current shoes hitting the rail. For example over a gap in the current rails, when the shoes hit the next section of the current rail, you do get a strange sound, which may sound like it's travelling down the train as each shoe hits the rail. Can't say I've ever noticed it on any other stock! maybe the 96s have different traction shoes, or the JLE may use a different type of power rail? Sorry, that's the only thing I can think of at the moment! |

Not necessarily , plenty of streams sound just like white noise and so does water coming out of a tap very fast. B2003 |

The running water sound, described in this thread, sounds like, well, water that is running - trickling - flowing gently from point a to point b. It's not a torrent, nor a gush, nor does it imply that the water is in any particular hurry. It's a gentle sound of water on its way from one part of the train to another, seemingly induced by the motion of the train itself. As the train starts up and gathers speed away from a station, you hear the water running past. As the train loses speed to enter a station, you hear it running back again. It doesn't sound like much quantity of water either. It just seems to gently make its way from one end of the train to the other, while more running water comes along, and so on. -- Ian Tindale |

I don't think there was any on the Jubilee line train I took yesterday, and I did listen! Most disappointing! -- "Mrs Redboots" http://www.amsmyth.demon.co.uk/ Website updated 22 November 2004 |
