Door open and close buttons on the London Underground.

[Dstock7080]

Thanks for all the info. I didnt realise what a complex history door buttons on the London Underground have had. It will be interesting to see if the replacement stock for the Bakerloo Line and Piccadilly Line get door buttons. Other than the D / S / 1992 / 1995 / 1996 stocks were any others stocks fitted with buttons? Did the A / C / 1986 stocks have buttons?

Other Stock to have door buttons in the past have been:
1938 Tube Stock, O/P/Q surface Stock

I'm almost certain that the C stock never had open door buttons. I don't think the A stock has had them either.

Looking at old photos, I can tell you that the 1986 stock had open door buttons, like the 1992 stock.

Thanks for the info. I didnt think that the A or C stocks had them but wasnt sure about when they were first introduced.

Thanks. I knew there was some others that had them. Did the 1938 / O / P / Q stocks only have open buttons or did they have close buttons as well? Also did the R stock have them as well?
