An Overground train driver has been arrested and suspended after he smashed his train through the barriers - inches away from Enfield Town station - while allegedly unfit to work through drink or drugs.
Firefighters evacuated 50 commuters as the train remained upright but came off the tracks and stopped just short of hitting a station building.
A 39-year-old man from Essex has since been arrested in connection with the incident on suspicion of endangering railway safety and being unfit to work “through drink or drugs”.
A spokesperson for Arriva Rail London said: “We cannot comment on this criminal case, but we can confirm that the driver involved in the low-speed collision at Enfield Town station has been suspended following a positive test for drugs or alcohol.
“We also continue to provide every assistance to the investigation by the Rail Accident Investigation Branch (RAIB).
“We have a zero-tolerance policy to drugs and alcohol and will always put the safety of our customers and colleagues first.”
A statement from the British Transport Police said: “A 39-year-old man from Essex was arrested 26 October in connection to an incident at Enfield Town station on 12 October, where a train crashed into the buffer stops.
“The driver of the train was arrested on suspicion of endangering the safety of the railway and being unfit to work on a transport system through drink or drugs.
“He has been released on bail until 19th November, and detectives continue to make enquiries into the incident.”
