Passengers waiting for the tube will have no shortage of distractions now that 14-foot HDTV screens are being installed in stations.
The cross-track projection (XTP) system, which allows high-quality digital images to be projected on to the walls opposite platforms, has been installed by advertising company CBS Outdoor for London Underground.
The system, which formally went live on Monday, means that commuters waiting for trains are now faced with moving advertising images displayed on the biggest screens in Europe
Any profits London Underground receives from XTP will be reinvested to improve the Tube. Before rolling out the ads to other stations the system was tested at Euston Tube station.
Following the success of the pilot, stations at Piccadilly Circus, Euston, Bank, Liverpool Street and Bond Street have now been kitted out with 23 high definition projectors and giant soundless screens that will show trailers for new film releases and other advertising.
