Which is why, in my Box, if there was a train in section we would only do the handover after it had cleared the Section signal.Another possible similarity is shift changeover time.
The accident occurred at 06.45 just when you would imagine the shift changing and 2 people in the box. This is well documented as a dangerous time in many occupations not just railways.
Cough. Moreton on Lugg!In the harsh light of investigation it seems incredulous that a professional, well trained, qualified person in a safety critical role can simply "forget" something, especially something as big as a train. However, there have been many accidents caused by this very thing, the signalman convincing himself that the situation is not as it really is, thankfully getting fewer and fewer as technology is introduced to mitigate human failings.
