At some point in history, a system was designed to prevent any subway operator from crashing his or her railcar with the one in front.
I can almost see the BOOM
My mother told me she found out about this doing research for a high school project of hers (over 20 years ago), it had already been working for a while: Just in case “an operator went nuts all of the sudden”.
It makes me wonder. When was this implemented?
Thanks to Alexcaban for the picture.
