Tube's XTP Displays

London Underground has installed high-definition colour projections and LCD screens in five of its tube stations - Piccadilly Circus, Euston, Bank, Liverpool Street and Bond Street - following a successful trial at Euston Station. This new XTP technology will be rolled out across another 30 stations at least, replacing old advertising posters. Yes. You didn't think London Underground was doing this to keep its punters happy, did you? It will get its share of the advertising revenue. Meanwhile, something as low-tech as air-conditioning won't be introduced for another decade - if then -, leaving passengers to swelter and faint!
