Crossrail has installed floor-to-ceiling platforms screen doors at each of the eight new underground stations on the Elizabeth line – that's roughly 4 kilometers of platform edge screens in total.
The first feature of the new Elizabeth line stations that distinguishes them from the existing 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, there will be a passenger information screen, which can also be used to advise passengers to use a different door if there is a fault.
Between the doors there will be vertically mounted TV screens to show advertising. The platform edge screens will be operated by the train signalling system, ensuring that door operation is closely synchronised to train movements.
These 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.
