A train which smashed through barriers and stopped inches from a station building was being driven by a man allegedly under the influence of cocaine.
Around 50 people were evacuated by firefighters from the morning Overground service on October 12.
It jutted over the tracks at Enfield station in north London after coming to rest just before glass windows of a ticket office at 8.15am.
The driver, 39, from Essex, was arrested on Tuesday on suspicion of endangering the safety of the railway and being unfit to work on a transport system through drink or drugs.
A routine blood test was taken and allegedly revealed cocaine present, The Sun reports.
The driver, who was said to be ‘experienced’, has been released on bail until November 19.
It’s understood he has been suspended by Arriva Rail London.
A source said: ‘This has caused shock among his colleagues because it’s a very serious incident.

‘Luckily, by the time the train hit the buffers it had slowed down and somehow managed to stay upright.’
Dramatic pictures of the crash showed the train raised up at an angle and jutting over the tracks.
Commuters described the scenes as ‘utter chaos’ and having seen ‘nothing like this incident’ before.

Two people were treated for minor injuries, but they were not taken to hospital.
The maximum penalty for a transport worker convicted of being unfit to drive because of drink or drugs is six months in prison.
Endangering the safety of people on the railway convictions can result in two years’ jail.
