Piccadilly Line: No service between Rayners Lane and Uxbridge due to a shortage of trains while we fix trains damaged by leaf fall. Please use the Metropolitan line to complete your journey. SEVERE DELAYS between Acton Town and Heathrow Airport / Rayners Lane due to an earlier signal failure at Northfields. Tickets are being accepted on London Buses, Elizabeth line and South Western Railway services via reasonable routes. GOOD SERVICE on the rest of the line.
