Commuters face disruption across three lines this morning, with delays and closures affecting routes through and around Chiswick.
The Mildmay Line is running with severe delays between Gunnersbury and Richmond following an earlier obstruction on the track at Chiswick Park. London Underground is accepting tickets via any reasonable alternative route while it works to clear the problem. Good service is reported on the rest of the line. TfL status updates
The Piccadilly Line continues its planned part-closure today — the final day of a three-day engineering window running Tuesday to Thursday. No service is operating between Cockfosters and Uxbridge. Trains are running between Acton Town and Heathrow, with Metropolitan Line services covering Rayners Lane to Uxbridge and District Line trains filling in between South Kensington and Ealing Common. Replacement buses are also in operation. TfL status updates
The District Line has also been affected, with no service between Earl's Court and Whitechapel, and severe delays elsewhere on the line. Tickets are being accepted on London Buses, the DLR, Elizabeth line, Liberty line, C2C and South Western Railway. TfL status updates
Anyone travelling through Chiswick this morning is strongly advised to check TfL's live status board before setting out and to allow extra time.
