The Bakerloo, Jubilee and Piccadilly lines have been hit by severe delays for the return to work on Tuesday after the Easter weekend.
The delays on the Bakerloo Line were due to the late finish of engineering work. There is also a part closure of the northern Line until April 11 between Golders Green and Edgware due to planned engineering works.
Meanwhile, the M25 J6 clockwise exit slip road to Godstone was closed due to a collision but has now reopened.
There are still delays of around 60 minutes in the area.
Similarly, Inrix reported long delays and one lane closed due to a crash on the M25 anticlockwise after J25 A10 (Enfield) with congestion to J26 Waltham Abbey.
