...at the Station which had the first public escalator (or ‘Moving Stairway’) installed back in 1911 - Earl’s Court! Earl’s Court is the only Underground Station that is served both by escalators and lifts (except the ones especially for wheelchairs) where you can see a ‘Way Out’ sign towards the lifts too! But here’s a fact that I bet you didn’t know about!
The Piccadilly platforms opened in 1906 - 5 years prior to the escalators, meaning that there was a Second lift shaft installed alongside the one we use today! Have a look at my pictures, and these doors used to lead to a passageway towards a Second Lift shaft that contained 2 lifts!
On the Ticket hall level, it was roughly where the Ticket Gateline (and Station Labyrinth) now is, but as you can see, there’s really no trace of it remaining but bare in mind that while exiting the station, you are standing above a hollow and disued lift shaft 63 feet deep!
It is unclear when the lift shaft was shut, but I believe that it was shut in 1989 when the lifts were replaced and the Ticket Hall extended.
You never knew about this despite using this station, didn’t you?!!
