There are currently severe delays and a part closure on the Piccadilly line.
There’s no service between Acton Town and Uxbridge because of a signal failure at the former, with long delays along the rest of the line.
Meanwhile, there’s a planned closure on the Overground between Hackney Downs and Enfield Town / Cheshunt, and on the tram system between Wellesley Road / George Street and Beckenham Junction / Elmers End / New Addington.
The Waterloo and City line is closed as usual on the weekend.
