Perhaps the reason it hasn't been noticed is that your assumption is
false. The fault is said to occur when trains are driven through a red
light very slowly, as happens for example in the case of a track circuit
or signal failure where a driver is given permission to do so. The
procedure is to go forwards slowly, get tripped, reset the tripcock and
proceed at slow speed to the next signal or for 3 minutes, or something
(I forget the details). It's been found that in these circumstances,
the tripcock can reset itself without stopping the train.

If you have up-to-date info on the number of SPADs on LU, please quote
numbers and source.
