Damage / Accidents
 
   
06.08.1989 50025 Invincible was heading at high speed to London with the 21:15 Oxford to Paddington service when it struck a section of rail which had been
  deliberately laid across the track by vandals. It derailed and travelled for half a mile, ripping up track before turning on its side and sliding even further.
  There were no fatalities or serious injuries, 50025 was written off.
