A train travelled at 80mph through Essex with one of its doors open after a screw became loose, a new report has revealed.

The Greater Anglia service covered 16 miles before a passenger spotted the fault and raised the alarm on August 22, investigators from the Rail Accident Investigation Branch (RAIB) found. 

The interlock system that checks to see if all doors are fully closed had failed after two bracket screws fell out, the report added.

Investigators said the door had remained open for 23 minutes.

RAIB warned Greater Anglia it needed to fix the problem on other Class 321 services after the train company discovered loose screws on “at least 60” out of 480 entrances.

The report added refurbishment on the faulty train that travelled with a door open had not appeared to involve tightening of screws.

The RAIB report said: "The apparent omission of yellow marks during refurbishment meant that one of the visual indications of a loose screw was absent, reducing the likelihood of checks identifying any loosening of the incident screws.

"The lack of yellow marks on these screws was not reported nor addressed at that time."
