The Elizabeth line has floor-to-ceiling platforms screen doors at each of the eight new underground stations – that's roughly 4 kilometers of platform edge screens in total.
One of the most notable features of the new Elizabeth line stations that distinguishes them from London Underground stations is how big they are – they'll have a platform length of over 200 metres. But over and above the size, perhaps the most obvious technical difference is the separation of the platform space, the people space, from the railway space.
Above each platform screen door is a passenger information screen, providing up to date destination information for passengers on the platform. The information screen can also be used to advise passengers to use a different door if there is a fault.
Between the doors there are vertically mounted TV screens to show advertising. The platform edge screens are operated by the train signalling system, ensuring that door operation is closely synchronised to train movements.
The platform edge screens are a critical safety feature for our stations. They provide a physical barrier between the platform and the track, ensuring that passengers are not able to access the tracks.
Extraction ducts have been incorporated into the design. These will help to maintain the flow of air through the station and, in the event of a fire, be used to extract any smoke from the platform space.
