February 14th will see the anniversary of an accident that has been described as ‘a one-in-infinity’ error.
The accident occurred in 1927 outside Hull Paragon station. In his haste to get a train away from the station, a signalman restored a signal to danger before the train had fully passed. This freed the locking bars on a set of points for 1.9 seconds. Within that elapsed time, his colleague set the road for a train to approach from the opposite direction. Unfortunately, he pulled the wrong lever, sending the departing train over the unlocked points into the path of the arriving train. His action took 1.6 seconds.
Because the two actions were virtually simultaneous, the trains collided head-on. There were 12 fatalities.
