Whilst sitting behind the cab bulkhead (and watching lots of LU DEVs), I've always wondered about the meaning of the various bongs, chirps, whistles, honks and other noises that the radio makes.
What exactly is the purpose of these sounds? Will Connect make similar noises?

The current system on the District, Metropolitan, circle and Hammersmith & City lines should work like this: The tone you should hear most often is the 'confidence tone'. It is supposed to be broadcast every 15 minutes so that if there are no conversations taking place, you can still be confident that the radio is working. It's not uncommon to go an hour without hearing a thing though - particularly as many trains need to have the transmit button pressed when the train op see's the indicator light lit  When the line controller opens a channel, we should get one 'beep' - though again that can vary. There is a third tone which is heard when the train op opens a channel in his own cab - the tone confirms the channel is open and the line controller should be hearing your message. No tone means the radio has not successfully opened a channel. As for Connect, I get the impression it's more like a mobile phone  . I'm sure we'll find out soon enough as we're supposed live on the District (D stock) within the next month. |

So long since I've sat and listened to the train radio, but do they still have the hourly / half-hourly chimes? (They were a simple bong or bing-bong.) Certainly a few years ago they still did on the Met at least. They were rarely at the precise time, but at least they gave a vague indication of the time.
As for Connect, I am not looking forward to the increased noise levels. Currently, out of all the phones in the room we normally have one with the sound on and the rest muted (they are all duplicates of one another so no problem in missing a call.)
With Connect there is no mute button (but you can turn it down to a quiet-ish ring). That means, in effect, 4 new "telephones" ringing simultaneously in the room.
It will spoil our usual calm and quiet atmosphere. I mean, how are we supposed to do the Times crossword and allow our tea to brew in ideal conditions if there's all this noise. And what with all these radio waves making the biscuits turn stale ;D
Might not be as bad if we can customise the ringtones. But no, that Frog should not be an option.

No tone means the radio has not successfully opened a channel. Does this one sound like a pair of whistles followed by a double beep?

The confindence tone sounds like a door bell. Bing Bong. When a channel is opened up on a hand-portable (cant remember bout train radio), its a bit like the nokia tone. Billa ba beep - Sorry thats the best text expression i can do. ;D  No sound is made when the controllr sends a message, though when the Train Operators press their transmit buttons it sends tone through |

Does this one sound like a pair of whistles followed by a double beep? Yes. The confindence tone sounds like a door bell. Bing Bong. Yes it should, but it doesn't always happen that way. No sound is made when the controllr sends a message, though when the Train Operators press their transmit buttons it sends tone through Actually we do get a single 'beep' when receiving a message from the line controller. I've experienced it with both the Met and District controllers. Incidentally, have the District drivers heard possibly the first female line controller yet? It's that nice young Spanish lady driver from Acton Town (please, do not post her name). It's a pity her accent is so strong and difficult to understand, cos she ain't 'alf good at the job considering she's only just started. |

Perhaps you should all pool your funds and buy a Faraday cage for the tea and biscuits, then convince one of the apprentices to get inside it As we understand it, the equipment will not be line/area based/split so basically each call will show up on each desk position, with the person responsible for that bit answering it. They cannot realistically design it specifically for our needs as we can often split the room operation in different ways on different days - dependant on service disruption. It's the same with our telephones at present. The person working the Jubilee will answer calls arriving on certain numbers, the Met will answers some others and so on. As for pooling our funds, we're not rich like those handle turners, and already have to supply our own biscuits. No, if it starts to have a detrimental affect on the crussons, then Connect will be hastily dis-Connect-ed and promptly dispatched from the nearest window ;D |

I suspect from the lack of response that train ops are never in the cab longer than 29 minutes, or don't hear the chime, or it doesn't happen anymore? Does the hourly/half-hourly chime still occur? There is a train radio I could switch on, but we get no reception on it - even though it's probably no more than 10 feet from the Line Controllers ;D

Errmmm, I have posted in this thread - and I believe I am a driver! ;D Perhaps no one else has posted as I have adequately answered the question? |

Oooh I know you're a driver, I know you have posted to this thread, but no I did not think anyone had answered the question adequately. But since you've taken that attitude, then quite frankly I couldn't care less whether it exists or not. |

Now fellow drivers, can you help me out here?......... I concur with all that Colin has posted. I haven't heard the Spanish lady on the radio but knowing her I can imagine she would be rather more soothing than the average controller! |

It seemed a bit off, but then shortly after that I visited another of your threads and can probably understand why you may have been a little peeved that day. Cheers |
