Dibbles Bridge coach crash

On 27 May 1975, a coach carrying elderly passengers crashed at the bottom of a steep hill at Dibbles Bridge, near Hebden in North Yorkshire, England. Thirty-three people on board were killed, including the driver, and thirteen others injured. It was the worst-ever road accident in the United Kingdom by number of fatalities.[1]

This article is about the 1975 accident. For the 1925 accident, see Dibbles Bridge coach crash (1925).

Accident

The coach, run by Riley's Luxury Coaches, was carrying pensioners on a day trip from Thornaby-on-Tees, North Yorkshire, to Grassington, in the Yorkshire Dales. While driving on a downhill stretch of the B6265 road between Greenhow and Hebden, stand-in coach driver Roger Marriott, a British Steel Corporation security officer, missed a gear. He then applied the brakes. The brakes had been serviced a week before the crash and had new linings, but as magistrates were later told, "defects" due to improper maintenance "meant there was no braking on the offside rear wheel".[2]

The brakes were insufficient to hold the coach, and it accelerated, heating up the brakes until they eventually failed as the coach travelled down the 1,400-yard (1,300 m), 1:6 (17%, 10°) gradient from Fancarl Top to the bottom of the valley downstream of Grimwith Reservoir. After crashing through a steel crash barrier and a 3-foot (1 m) high stone parapet above the bank of the River Dibb, it landed on its fibreglass roof in the garden of a cottage 17 feet (5 m) below. The aluminium sides of the coach then buckled on impact with the ground.[2][3]

The son-in-law of the cottage owners, London barrister (now painter and sculptor) Lincoln Seligman, was having a barbecue in the garden at the time and was first on the scene. He later gave an eyewitness account to the Teesside Evening Gazette: "There were screams. I dragged some people out ... I don't know how many".[4]

Inquest

An inquest at Skipton Town Hall, in July 1975, recorded a verdict of accidental death on the victims. Jury foreman John Mitchell said the accident was caused by the inability of the driver to negotiate the bend, owing to deficient brakes on the coach, due to possible lack of care in the maintenance of the braking system.[2] The pathologist reported that the main cause of the loss of life was the crushing of the victims between the seats.[5] The proprietor of the coach company was later fined £75 (equivalent to £634 in 2019[6]) for running a motor vehicle with defective brakes.[7]

Aftermath

Even before the crash there had been a campaign to have electro-magnetic retarders fitted to all coaches. An electro-magnetic retarder uses the rotation of the axle to generate electricity, the energy for which has to come from the movement of the axle. The use of such a retarder means that the frictional brakes are kept cool for use at slow speeds. Local newspaper The Yorkshire Post staged a trial two weeks later: a coach which had been fitted with the retarder was put out of gear and allowed to run away down the hill without braking, and the retarder kept the coach's speed within safe limits. The Dibbles Bridge crash brought the issue to a wider public; ultimately, legislation was passed requiring improved braking systems.[2]

A memorial service was held at St Paul's Church, Thornaby, in May 2015 to mark the fortieth anniversary of the crash, when a memorial plaque was unveiled listing the names of those who died.[8]
