Just saw this on the news. No doubt it will be one more thing for commuterdom to moan about! news.bbc.co.uk/1/hi/england/london/6108906.stmIt was on the BBC london news, it showed the N/b at Victoria, dont know whether it was a mock up or the real thing, was quiet, so maybe a mock up, and the link says it will be early 2007 until the first test screens start operation. |

The Aldwych platform at Holborn Picc has been used for testing this type of equipment, so I suppose that the tests have finally been completed.
TBH it would probably save a LOT of money in terms of employing safety-critical staff to stand on trolleys and put up the posters, not to mention the cost of the posters themselves. No doubt the H&S mob are quite pleased as well.

No doubt the H&S mob are quite pleased as well. Is traction current switched off when putting up these posters or are these trolleys specially designed to prevent people from falling on tracks? I've never thought about how they put up these things. There must be more to it than I thought... |

Surely the space these projectors take up, could be used by a fan system of some sort, for when it is hot?  |

They already do this stuff in Hong Kong.
So much for the world in reducing carbon emissions!

Maybe, but the projectors are another source of heat to warm things up a littled bit more.

The trouble with these is the amount of energy they must use. Doubtless the extra advertising revenue will be more than the electricity bill, but it's certainly not environmentally friendly!

According to the Viacom [advertising firm responsible] spokesman, they use very little power.

I've never thought about how they put up these things. There must be more to it than I thought... The posters on the track walls are put up at night with guys using ladders. I've never seen any 'special' equipment ever used. As for the new electronic sites, perhaps a DVD in socket could be provided for station staff on nights ;D |

Thats a great idea! ;D
Echo what Simon has said, I only have ever seen ladders been used.

Those electronic whiteboards - anyone know if you can connect a DVD player to them ;D
It might prove useful if Viacom used this technology also to display BBC news - like on display at NR stations - or perhaps travel news?

Travel news would be especially helpful - give another outlet for network information at stations. Perhaps a map with greyed out sections where there are disruptions?
And yes, low power, Viacom would say that wouldnt they!!!
The interactive whiteboards I've used can all have a DVD player connected up - most commercial projectors have the right connections.

I would like to see them connected to the CCTV to show the train entering the station at different angles! Sooo coool! ;D

Travel news would be especially helpful - give another outlet for network information at stations. That would be very helpful. One of the major problems with the way delays and engineering works are advertised is that the posters are almost all in the ticket hall area with nothing on the platforms. People rush through the ticket hall ignoring all the notices, then get onto the platform and wait there for ages for a train that isn't going to come. They would know they were wasting their time if they would only take a few seconds to read the displays in the ticket hall.  |

And it'd stop the problem of transferring on to a line which is suffering from delays, e.g. going from the central to the district at bank/monument when the circle's up the wall and causing all kinds of bother.
Alternatively, should you put mirror balls/shadow puppets in front of the projectors?

The hot air that these blow out should technically be cancelled out by the power of cold air running through the tunnels assuming all trains are moving, surely?

Science TC: the air in tunnels is NOT cool (though occasionally it feel that way when it's moving fast towards you). It takes the temperature of what is around it, hot passengers, train brakes etc., and what is brought down from above. So the comment above is correct: these machines will make the warm air even warmer, and in the summer more uncomfortable.
And, yes, to install them just when the rest of the world is beginning to take global warming seriously is insensitive to say the least.

Trust me to pick a forum with an old science teacher on... ;D ;D
I presume these will be tested in passenger service at Victoria as they are installing a new groundwater cooling system there?

All trains on the New York Subway are air conditioned. Hardly any stations are. Even though it's almost all a SSL, the result is that stations turn into ovens (far worse than the tube) in summer. Throw in the complete uncertainty regarding when your train may or may not appear (the signalling is too ancient on many lines to even consider train describers) and you end up with a lot of very unhappy people, and stampedes to get into the freezer like train when it finally decides to arrive.
