[Il] explique les causes de l'accident de Péage et montre comment il a déterminé des décisions techniques pour améliorer le système mis en cause : sur le réseau du PLM il n'y avait pas d'«enclenchement de continuité», c'est-à-dire que le sémaphore permettant l'entrée dans un canton et celui marquant la sortie du canton n'étaient pas automatiquement liés, ce qui permettait au «bloqueur» de «rendre voie libre» en manœuvrant le sémaphore d'entrée dans un canton occupé par un train.
