A reduced service is running on the Metropolitan Line "until further notice" after an issue was discovered with some trains.

Transport for London (TfL) says routine inspections revealed a "fault with some of the wheels".

From today (April 11), a revised timetable is in operation on the Met Line, which affects commuters in Harrow and all of the other stations on the line.

TfL says trains are operating between Baker Street in central London and Amersham and Chesham in Buckinghamshire every 30 minutes, between Watford and Baker Street every 15 minutes, and between Uxbridge and Aldgate every 15 minutes as well.

A statement from TfL said: "From Monday 11 April we will be running a special timetable on the Metropolitan line until further notice.

"This is due to a fault being identified on some of the wheels on a number of Metropolitan line trains during our regular and routine inspections.

"Safety is our top priority, and as a precautionary measure, we have increased the rate of inspection of these trains to make detailed checks on the entire fleet.

"The timetable changes will ensure we continue to run as frequent and regular service as possible while inspections take place and the fault is resolved."
