Following on from the long-running thread on things you saw travelling on BR that you don't see today at www.railforums.co.uk/threads/trivia-things-you-saw-travelling-on-br-that-you-dont-see-today.151953/, I thought it would be nice to have a similar thread on things you used to see when travelling on the London Underground that you don't see today. Here's a few to start you off: Guards on trains. Manned ticket collectors' booths. Wooden slatted escalators. "Passimeters" (free-standing ticket offices that also doubled as ticket collectors' booths, where you had to buy or show a ticket on your way in and show your pass or give up your used ticket on your way out - I think a few of them are still in situ but no longer used). Edmondson card-sized tickets, including some green ones and some yellow ones with a chocolatey brown magnetic rear side to operate the old-style (pre-1987ish) automatic ticket gates which had signs on saying "yellow tickets" as you had to have one of those yellow tickets to operate them. Old-style tickets normally just had the fare and station of issue on them. Free-standing ticket machines with a diagonal illuminated panel at the top indicating the fare for tickets from that machine.
