BBC1 London news this evening showed pictures of the rope that is
supposed to be at the heart of the problem. It looked like the rope that
used to be the manual tripcock resetting device on older tube stock. Is
that still its use? Seems a bit primitive for 1995 stock.


Indeed the 95 and 96 stocks still use the rope reset, as do the D
stocks. The C stocks have a push-button reset. Not sure about the
others.

It's no problem simply pulling on the rope to reset the tripcock.
After all, it's (hopefully) not that often that it should need to be
used!

I've never seen the news due to working, but I'm not sure how the rope
could be the problem. This is only used for resetting the tripcock.
As I understand it, the tripcock wasn't activating when hit by the
trainstop which is the problem? Obviously I am happy to be corrected -
as I say, I'm always working when the local news is on!
