 Furthermore, he considered that the severity of damage showed that no braking at all had been applied to the runaway.The brakescrew on the runaway brake van had been bent in the collision, and the nut was at the bottom of the working section of the screw, indicating that the brake had been off at the time of collision.Tyler therefore rejected Cooke's evidence that he had applied the brake as the train was arriving at Round Oak; the coupling had failed when he released the brake, but he had reapplied the brake on becoming aware of the breakaway; this had initially had some effect, but the runaway had then skidded down the incline with gathering speed.
