The Irk Valley Junction rail crash occurred on 15 August 1953 at Collyhurst, just over a mile from Manchester Victoria station. At that point, the electrified line to Bury passes through Irk Valley Junction, so called because it lies on a viaduct above the River Irk. At 07:40 on the morning of 15 August 1953, the 07:20 electric train from Bury collided with the 07:36 steam passenger train to Bacup hauled by a Class 4P 2-6-4 tank engine. The leading electric coach struck and overturned the steam engine and smashed through the parapet wall. The front of the carriage fell 40 feet (12 m) onto the bank of the river; the rear fell 70 feet (21 m) into the shallow river itself. Nine passengers and the driver of the electric train were killed.
