DMU Accidents

DMUs have had their fair share of mishaps through the years and this section is an attempt to document them.

If you have any notes or photographs please submit them to be added here. I would also welcome further information on any of the accidents featured here.

Many of the accident reports are available on-line at

Collision involving DMU / Steam

Info from Bill Read

A 6-car DMU travelling from Leeds City to Hull collided at speed with the rear of an unfitted goods train running at about 25mph, and hauled by an 8F. 5 persons injured. The freight train divided and the DMU continued forward for 75 yards, with the leading bogie derailed, pushing in front of it a 20-ton brake van and two wagons. The front of the leading coach (E50554?) was stove in and there was damage to the cab floor and fittings. The DMU passed a red signal.

18/08/60 - Between Castleton South Junction and Mills Hill, LMR

Collision involving DMU / Trolley

Info from Richard Greenwood

A Manchester-Heywood-Bury-Bacup late morning dmu hit a platelayers trolley on the line. Delays of up to 55 minutes before normal traffic resumed.

02/09/60 - Castlecary, ScR

Collision involving Class 126 / Steam

Info from Bill Read

A 6-car Inter City DMU travelling between Glasgow and Edinburgh collided at about 25 mph with the rear of a slow-moving ECS train hauled by a Class 5MT running tender first. 3 passengers injured. Damage to the DMU was confined to buffers, headstocks, gangway frames and couplers. The shock of the collision was transferred through the 4-coach ECS train resulting in the first coach being forced upwards from its leading bogie and impacting with the smokebox of the locomotive. The DMU had been irregularly admitted into an occupied block section.

New Mills Collision

12/10/1960 - New Mills (Central) Station, LMR

Collision involving Derby Lightweight / Steam

Info from Bill Read, John Darwent

Three Derby Lightweight twin units, built 1955, collided with the rear of a goods train hauled by a Class 8F (48443), which was standing at New Mills (Central) Up home signal. 3 injured. The leading power car (M79170) was wrecked and the following trailer car was crumpled by collision with the leading car. The two rear units were little damaged. The DMU had passed the Strines Station starting signal at danger. In the image M79170 has been lifted off it's bogies and sits on a wagon. There's a fair bit of debris at *this end* of the bogies but no visible damage to this end of the vehicle, the tarpaulin at the cab end suggests damage there so the vehicle may have been turned when being put on the wagon. The crane is from Lostock Hall MPD, and the photo was due to appear in Trans-Pennine Publishing Ltd's book "British Railway's Breakdown Cranes" by Peter Tatlow, Alan Earnshaw and David Carter (ISBN 1 903016 35 5).Picture by Bill Warden.

16/11/1960 - Pontrhydyfen Jct, WR

Collision involving Class 116 / Steam

Set CAT343 was operating a journey from Neath to Treherbert when the leading car, W50125 was struck by a runaway coal train headed by ex-GWR pannier tank 9737, on the single line track at Pontrhydyfen Junction. The DMU driver was killed in the accident and the leading car was so badly damaged that it was written off and later scrapped at Swindon Works.

24/11/1960 - Between Pontrhydyfen and Cwmavon, WR

Collision involving Class 116 / Steam

Info from Bill Read

A 3-car DMU travelling from Swansea High Street to Barry Island was in a head-on collision with an unfitted goods train (weighing 620 tons) hauled by a Class 57XX Tank locomotive running bunker first. 2 persons killed and 26 injured. The point of collision was on a single-line section with a gradient of 1 in 42. The locomotive drove some five feet into the leading power car which telescoped some ten feet into the intermediate trailer. The locomotive was also extensively damaged and 8 wagons were wrecked. The goods train was travelling too fast down the gradient and had an insufficient number of wagon brakes applied to enable it to stop at the Pontrhydyfen signal.

Royton Accident

10/08/61 - Leeds City Station

Collision involving Class 101 / Class 45

Info from John Darwent and Bill Read

Peak D105 running light to Neville Hill over-ran signals and collided with a Leeds - Scarborough DMU (two 4-car units) almost opposite Leeds East Signal Box. Leaking diesel caught fire and the leading two DMU vehicles (51440 & 59533) overturned, but were returned to traffic after repair. One killed, two injured. The leading motor coach (51440) turned over and slid on its side, demolishing the parapet wall of a bridge and releasing fuel oil which then ignited. The second coach (59533) also fell on its side, but the remaining six coaches were little damaged. All returned to trafic. The driver of the locomotive mistakenly accepted the signal that had been cleared for the DMU.

Hessle Road Derailment

Derailment involving Class 104

Info from Ian Fleming and Mick Nicholson

In the final week of the old mechanical cabin. Trains were being hand signalled, the Class 104 (59226 closest) ‘split’ a set of wrongly clamped points. The photographer said: “Within hours the mess was cleaned up and normal working soon resumed, today it would be a ‘scene of crime’ and the job stopped for a week”! Mick Nicholson.

25/01/1963 - Bracebridge Gas Sidings Signalbox (near Lincoln), ER

Collision involving DMU / Steam

Info from Bill Read

A 2-car power/trailer DMU travelling from Grantham to Lincoln Central collided with the rear (tender) of a stationary Class B1. 2 persons killed, 3 injured. The power car of the DMU was extensively damaged at the front end and the leading bogie was driven back two feet. The light engine had been allowed to wait on the Down line in preparation for reversal and its presence there had been forgotten by the signalman.

10-12-1963 - Between Glendon Junction and Kettering, LMR

Derailment involving Class 127

Info from Bill Read

Derailment of Class 127 + unidentified twin unit. M51609 – no other cars identified. Minor injuries. While travelling at 60mph, a complete engine and torque converter weighing 2.5 tons fell from M51609 causing extensive damage to the vehicle and derailing all cars. A small fire broke out. The conclusion was that the unit was released into service, after overhaul at Derby Works, with loose torque-converter securing bolts. This caused progressive overloading of other bolts, brackets and cardan shaft until final failure.

12/03/1964 - Shoe Mill, Baxenden, LMR

Fire involving Class 113

Info from Andrew Dyson

An engine fire destroyed a vehicle. More Details.

Bradford Collision

03/06/64 - Bradford (Exchange) Station, NER

Collision involving Class 108 / Steam

Info from Bill Read, Malcolm Paul and Peter Mullen

The DMU descended the steep gradient into the station and collided with the stationary parcels train at about 50 mph. The leading car was destroyed. Damage to the steam locomotive and M52059 was minimal. More Details.

10/10/64 - Between Milbrook and Wilshamstead, LMR

Fire involving Class 127

Class 127 on fire after breaking cardan shaft. M51591 (trailing car). 1 passenger killed, 4 injured. The rotating ends of the broken cardan shaft punctured the fuel tank. The resulting fire caused some damage to the trailing cab but did not penetrate the saloon. Examination of other units found that some 40 cardan shafts were bent, probably as a result of careless handling when torque converters were changed, and this was assumed to have caused the failure.

25/05/65 - Llanddaniel Occupational Level Crossing, LMR

Collision involving DMU / Road Vehicle

Info from Peter Mullen

A Crewe – Holyhead DMU passenger train running at 45mph struck and wrecked a Vauxhall Victor saloon car which was going over an unclassified level crossing. More Details.

October. '67 - Sough Tunnel (near Darwen), LMR

Fire involving Class 112

Info from Andrew Dyson

51705/24 caught fire in Sough Tunnel. These were cut up at Spring Vale in April 1968 by staff from Accrington depot. Cutting the unit up was only undertaken on Sundays, as staff had to work Monday to Friday, and management wouldn't free them on these days to cut the unit up. The fire was so intense that the sole bars in the middle on the units melted, causing the unit to sag. The cause given was the cardan shaft shearing, flailing about rupturing the fuel tank. Lancashire Telegraph article.

Collision involving Class 126 / Class 24

Info from Bill Read

A 6-car Inter City DMU travelling between Glasgow and Edinburgh was standing at a signal when it was run into at the rear by a light engine, Class 24 Diesel locomotive D5122. 2 persons killed and 3 injured. The rear car of the DMU, SC 79092, and the Class 24 locomotive were destroyed by the collision and subsequent fire. During a track-circuit failure, general confusion and slack working practices resulted in the Class 24 being admitted to an occupied block section. Having done so, the locomotive travelled too quickly to be able to stop short of an obstruction.
