They're not all plasma. They have a lot of shortgun CRTs - you can tell 
because they're bright, burnt-in and have no visible join. Look at the 
announcement boards by the patform entrances for examples, IIRC. They only 
use plasma on the main boards overhead in the departure area.

BTW Jon - no backlight on earth is going to work in Paddington. They have 
enough problems with visibility as it is; they'd need something really 
massive to backlight that amount of LCD, and the heat it would generate would 
be tremendous, way more than the current efforts. 

I don't know why they don't just use CRTs - cheaper, easier to maintain, 
brighter, altogether more excellent. 

Cheers,
