On Monday 23 January 1911, a collision between a passenger train and coal train on the Taff Vale Railway line at Hopkinstown, outside Pontypridd in Wales, resulted in the loss of eleven (twelve according to the official report) lives. The accident, also known as the Hopkinstown rail disaster or the Coke Ovens collision, occurred at 9:48am, when the 09:10 from Treherbert to Cardiff passenger train heading towards Pontypridd railway station, carrying roughly 100 people on board, rounded the bend at Gyfeillion Lower signal box with a clear signal ahead. The train collided with a stationary coal train that was using the same line.
