A date now seems to have been set for JCDecaux’s giant LED at London’s Waterloo Station (originally scheduled for September ) to go live.
It’s our understanding that the LED is now fully installed and functional but switched off during the day, with content testing taking place during the very early mornings.
JCDecaux tweeted  on New Year’s Day “40 days to go until the launch of Waterloo Motion, the largest indoor advertising screen in the UK! #40m #Waterloo #railmotion #comingsoon“
Waterloo Motion is 40.3m x 2.8m (112.8sq m).
