A very interesting thread, it's incredible really to think that someone would go to the trouble of designing and building all that elaborate machinery to perform what is a fairly mundane task of saving people from walking up the stairs !
What a pleasure it would be to go to work if your full time job was to operate and maintain that
On a very slightly different note I remember as a child in the 60's that a lot of large department stores had an elaborate system of pressurised pipes to move sealed capsules of money, receipts etc between departments. I wonder if originally they would have been steam powered ?
Anyone else remember these things ? :-
