Would I be correct in thinking that had the LU service departed Chalfont & Latimer some time earlier (possibly even seconds) then the LU driver would not have seen the signal revert back to danger and thus would not have had any indication of anything being amiss until they spotted the Chiltern service heading towards them?
If so I'd imagine RAIB may well comment on this possibility and the good fortune that it hadn't already departed.
Exactly right. My understanding is the LU driver was just starting to move when the signal returned to danger. A couple of seconds earlier and he’d have been on his way. There is the possibility that this might have given the Chiltern driver more of a cue that something was amiss.
