Forty minutes later he accepted the 09:10 passenger train from Treherbert to Cardiff onto the same line, having forgotten the coal train was still there. Signalman Hutchings at Gyfeillion Lower had not given the Train Entering Section signal that would have reminded Quick. He had also not put his signals back to Danger when he realised the conflict. The two-position block instruments they used had a setting called Line Clear but no separate setting for Line Blocked. At 09:48 on Monday 23 January 1911, the passenger train carrying about 100 people rounded the curve at Gyfeillion Lower with a clear signal ahead and collided with the stationary coal train. The front carriage's underframe lifted as it crumpled and drove like a battering ram through the carriage behind it. Twelve people died.

The carriages of the period were built on heavy wooden underframes that gave them strength along their length but failed in compression. When the front carriage struck the back o...
