If you are travelling to Heathrow Airport by Tube early on Saturday, 18 June, the first train from Cockfosters will depart nine minutes later than normal at 0519, due to engineering work to improve Piccadilly line services.

That first train to Heathrow will call at Oakwood at 0521, Southgate at 0523 leaving Arnos Gross at 0528.

But the 0518 from Arnos Grove to Heathrow will operate as normal.

The engineering work is being carried out by Tube Lines, who are responsible for the maintenance and renewal of the Piccadilly line.
