All Central line services are now running with minor delays following severe disruption caused by late finishing engineering works.
The line was suspended this morning between Leytonstone and Loughton, and between Hainault via Newbury Park and Grange Hill.
A spokesman for Transport for London apologised for the problems.
He said: "Trains are running now with minor delays on all routes.
"Apologies for the inconvenience caused today."
