Piccadilly line part closed to Cockfosters as Elizabeth line recovers

Updated at 10:15. The picture has changed again and the morning headline no longer holds: the Elizabeth line is nearly fixed, while the Piccadilly line has gone down. It is now the worst line on the network.

This morning: what to avoid

Piccadilly line — there is no service at all between Arnos Grove and Cockfosters while TfL fixes a signal failure at Arnos Grove, with severe delays on the rest of the line. That hits north-east London and the run to Heathrow, so this morning’s advice to take the Piccadilly to the airport no longer stands.

Tickets are being accepted on London Buses, Great Northern, the Elizabeth line, South Western Railway and the Overground via any reasonable route. There is no need to pay twice.

From Cockfosters, Oakwood and Southgate take a bus to Arnos Grove and pick up the train there. For Heathrow the Elizabeth line is now the safer bet, with only minor delays left.

Elizabeth line — the Paddington signal failure is fixed and only minor delays remain towards Heathrow and Reading. Victoria line — minor delays from train cancellations. The rest of the Tube, the DLR, the Overground and the trams are running normally.

Tonight and the way home

After 23:15 tonight the Windrush line (the former East London line) closes between Surrey Quays and Clapham Junction / Battersea Park. No replacement buses run at all — use ordinary London buses and the Tube. If your evening runs late there, leave earlier.

On the Mildmay line the 22:29 Stratford to Richmond train terminates at Camden Road at 22:49. This is the fourth and final evening of that restriction.

Bigger work is already booked for the weekend of 10-11 October. The Circle line will not run between Edgware Road and Aldgate via Victoria. The District will be closed between Edgware Road / Tower Hill and Ealing Broadway, Kensington (Olympia), Richmond and Wimbledon, with replacement buses and the Mildmay line between Gunnersbury, Kew Gardens and Richmond. The DLR shuts between Stratford International and Woolwich Arsenal with no replacement buses: use the Elizabeth line for Woolwich.

What to do

Coming in from the north on the Piccadilly, allow an extra 40-60 minutes and remember your ticket is valid today on buses, Great Northern, the Elizabeth line, SWR and the Overground. For the airport, the Elizabeth line is now the better route. Forecourt prices are in our fuel roundup; October closures in our guide to TfL works.
