In article , Roland Perry
writes It was London Transport which recalculated its route measurements to Kilometres back in 1972 . Ironically they chose Ongar as the 0 datum I think they chose Ongar because it was the furthest east. Actually Upminster is slightly further east (5561xx versus 5550xx on the OS grid), but it's further by rail from the first common point (Mile End). I was recently explaining the Ongar system to someone and thought about this. There were other possible zeros, such as Mantles Wood Junction, High Barnet, or Morden, but Ongar has the advantage of being a terminus with clear buffer stops on a line that had no plausible likelihood of being extended. -- Clive D.W.

That's because of the idiot privatisation attempt - Metronet and Tube Lines chose different suppliers. Metronet went into administration in 2008. The new signalling system for the met line has only just gone in. |

A light bulb is about as simple as you can get. Imagine if they tried the same on the roads..! Incandescent light bulbs have a short life and need frequent replacement. The light is also not consistent, dimming and getting more yellow over time. LED arrays are far better. But in railway terms, no lineside signals at all is better still. I disagree. How is someone working trackside supposed to know whether a train is signalled or not..? An app on their phone or iPad tells them. Various platforms have signalling diagram monitors which provide this info to platform staff, and no tungsten filaments were electrocuted in the making of this image.

The metric version would be, "give them a cm and they'll take a km". Which unfortunately doesn't scan very well, "inch" and "mile" not only sound different, but are only one syllable each, as opposed to four syllables each. You might try "give them a metre and they'll take a million", which has a nice bit of alliteration, but on everyday scales an inch is small, but a metre is not-small. I suppose you might shift to weights, and say "give them a gram and they'll take a tonne"; or perhaps volume, with "give them a mil (ie millilitre) and they'll take a lakeful", which trades the lack of a big volume unit for an extra "l" from "lakeful". #Paul |

The driver made several announcements that he was going to Olympia to be sure that everybody who don't want that destination go off. But no attempt was made to stop people using it if they did tim |

This has become a meme about "Charing Cross" (the original one only having a plaque) and an unspoken implication that it has always been the case (long before the AA) My mention of Ongar was done because it is an interesting Railway factoid and also an example to our Aberdeen correspondent that the London Transport they remember as an example tradition of the good old days initiated a major Metrication exercise 40 years ago, it was from that you seem to have decided that you want to hold a point scoring debate ,an activity you are renowned for by mentioning the Post office datum which turns not to be the only candidate It's the original one, though (if you ignore the Romans). And the Turnpikes used a range of gateways (not unlike the AA did originally, perhaps they modelled themselves on those). for distances too and from London . At least the Ongar one can be verified The Post Office one can be as well. The mystery about the Charing Cross/AA one is that as far as I can tell no-one has ever been able to expand on what it says on that fairly recent and vague plaque. I think I'll do a FOI on Westminster City Council, and see what they have to say. That would be interesting, I wonder if the Ordnance survey has any information anywhere. GH -- Roland Perry |

Sorry for posting earlier (finger trouble, and nothing new added). What I'm trying to discover is why the BBC and others are peddling this old wife's tale, the details of which are discussed earlier in the thread. -- Roland Perry |
