Ais Gill rail crash (1995)

From Wikipedia, the free encyclopedia

The Ais Gill rail accident occurred near Aisgill, Cumbria, at about 18:55 hrs on 31 January 1995 when a class 156 Super-Sprinter was derailed by a landslide on the Settle-Carlisle Railway line and was subsequently run into by a similar train travelling in the opposite direction. The conductor of the first train, Mr Stuart Wilson was fatally injured in the collision.

The subsequent report made by Her Majesty's Railway Inspectorate was the last report to be submitted under the terms of the Regulation of Railways Act 1871, which was repealed in 1995.

[edit] Events

A Class 156 Super-Sprinter formed the 1626 Carlisle to Leeds via Settle service (headcode 2H88). It could only proceed as far as Ribblehead railway station, about 12 miles north of Settle, as the lines from Ribblehead to Settle were blocked by flooding; so it had to return to Carlisle. The driver changed cabs as the train was now heading northbound instead of southbound, and proceeded back over the Ribblehead Viaduct, and on to Aisgill Summit, the highest point on the line at 1169ft above sea level. It was dark and raining heavily.

Near Aisgill Summit itself the train hit a landslide. It derailed across both tracks, and the cabin lights went off plunging it into darkness. The injured driver managed to make an emergency radio call to Crewe Control Room telling them of the incident. Unfortunately the actions at Crewe and York Control Rooms did not prevent the subsequent collision. The conductor escorted passengers into the rear unit, which was across the northbound track. He then returned to see the driver who was still in the cab.

Meanwhile another Super-Sprinter train forming the 1745 Carlise to Leeds service (headcode 2H92) had set off from Kirkby Stephen railway station around five miles to the north. About a quarter of a mile before the derailed train, the driver saw its red headlights and started to make an emergency brake application, but the train had no chance of stopping before impacting the derailment. The resulting collision killed the conductor of the derailed train, and seriously hurt several passengers: 30 people on the trains suffered some kind of injury. The signalman at Settle Junction signal box was informed of the accident by the conductor of the 2H92 service and the emergency services were then alerted.

[edit] Enquiry

The official enquiry into the accident concluded that the conductor of the derailed train (2H88) failed in his paramount duty to protect his train in the event of an incident by laying down detonators and displaying a red flag one mile away from the obstruction. As the driver of the train was incapacitated, the conductor should have protected the line in front of the train in case another train should approach from the opposite direction (as in fact actually happened). The time between the initial derailment and the subsequent collision was about six or seven minutes which would have allowed a much greater warning time to be given to the second train, and may have prevented the collision or at least reduced its impact.

Further recommendations were made concerning the inadequate communications between Railtrack Control Rooms and inefficient use of the National Radio Network. A "group call" to all trains in the vicinity of the incident could have been made by the Control Room and might have alerted the second train to the obstruction in time to prevent the collision.

[edit] Other incidents

In 1999 a similar incident occurred on the Settle and Carlisle line at Crosby Garrett, north of Kirkby Stephen, where a landslide caused a Carlisle-bound Sprinter to derail. The driver set off a warning horn mounted on the track, and although a southbound goods train hit the Sprinter, nobody was seriously hurt. This took place during bad track conditions similar to the 1995 incident.
