However, the express driver and one passenger were killed instantly, whilst another passenger succumbed to injuries a month later. A number of people received impact injuries and burns and many were also treated for smoke inhalation. Rescue efforts were assisted by the location of the accident, which was adjacent to the M602 motorway, enabling easy access for emergency services.
The force of the collision threw the rearmost tanker to the side, but the next two wagons were thrown into the air, with one falling back onto the passenger locomotive. The wagons were badly damaged and escaping fuel oil was ignited by the hot exhaust gases of the locomotive, setting fire to it and the leading two coaches. Fortunately, the leading coach was empty of passengers or the death toll would probably have been much higher.
