An investigation has been launched after two trains nearly crashed into each other in London after one went the wrong way up the track.
Transport for London (TfL) confirmed a Chiltern Railways service nearly collided with another train at 9.50pm on Sunday.
A picture, taken near Chalfont & Latimer London Underground station in Buckinghamshire, shows the two trains just feet apart with engineers and guards monitoring the scene.
No one is believed to be hurt as a result of the incident but the Rail Accident Investigation Branch is investigating what happened.
A TfL spokesperson said: ‘We apologise to customers disrupted by the closure of the Metropolitan line between Chalfont & Latimer and Chesham.
‘This is the result of an incident involving a Chiltern Railways train near Chalfont & Latimer station last night.
‘We are working with Chiltern Railways to determine exactly what happened, and our engineers will repair the railway to return it to service as quickly as possible.’
Chalfont & Latimer station serves both the Metropolitan line on the London Underground and Chiltern Railways trains between London Marylebone and Aylesbury.
A Chiltern Railways spokesperson said: ‘We have an excellent safety record and are working with the Rail Accident Investigation Branch to understand the causes of this incident.
‘We apologise for the disruption caused to customers using Chiltern Railways and London Underground services in the area.’
The Metropolitan line is currently still suspended between Chalfont & Latimer and Chesham. Tickets are being accepted on local buses as an alternative.
