Default Tube Trains Sent On Collision Course

I tentatively think this focus on the lack of signals is a bit
misleading. Ultimately, all safety on non-ATO lines depends on
drivers correctly responding to signals (barring tripcocks - am i
right i thinking these are only present at a fraction of signals?).
If we accept that stopping at a red is an acceptable part of the
safety mechanism, why can't we also accept that stopping at the
absence of a green, or the absence of any signal, is?


Tripcocks are present at all home signals on LUL lines.


You meant to say:

Tripcocks are present at all stop signals on LUL lines.

Didn't you?
