Damage / Accidents
 
18.05.1969 While driving the 22.15 London Euston to Glasgow it endured a low speed collision with the failed 21.30 London Euston to Inverness near the top of Beattock summit.
  In accordance with the rule book driver Brown buffered up to the rear of the failed train and pushed forward. The Inverness train created a gap and stopped again.
  Unfortunately driver Brown was unable to stop in time and collided at approximately 10mph. Driver Brown and secondman R. Lunny became trapped in their cab.
  Sadly driver Brown lost his life.
