An investigation is underway after a dog got dragged along a platform after its lead got stuck in the train doors.
The accident happened when its owner Rose Barry got her hand stuck in the train doors at Elstree and Borehamwood station.
She was able to pull herself free but the lead was still stuck which meant the dog was pulled along the platform.
The dog was found dead in a tunnel near the station.
The Rail Accident Investigation Branch (RAIB) are now investigating the incident which happened earlier this month. The investigation includes:
- Procedures used for dispatching Thameslink trains.
- The ability of train doors to detect trapped objects.
- Systems used by Govia Thameslink Railway to ensure the competence of drivers when operating and dispatching trains on this route.
