WINNIPEG, Nov. 30 /CNW/ - Canadian based SideTrack Technologies last night (Thurs) completed final testing of its LED display system on the prestigious Heathrow Express train service which carries more than 100,000 passengers a week between the Heathrow Airport and London's Paddington station. The Company provides advertisers with the ability to deliver a 15-second advertisement which lights up the dark tunnel walls as the trains pass the display at speeds of around 60 mph. A total of 360 individual LED bars have been installed along a 450m stretch of the tunnel - creating a display nearly half-a-kilometer in length. The LED display will be seen by passengers arriving into London from Heathrow Airport.
