Havering commuters are facing train delays for the second day running.
A signalling problem at Gidea Park station delayed trains on the Liverpool Street to Shenfield line by up to 30 minutes this morning, while some trains were cancelled to ease congestion.
Delays continue, but all lines through Gidea Park are now reopened.
Yesterday morning, trains on the same route were delayed by up to 45 minutes because of a fire at Manor Park station.
The line is operated by Greater Anglia. A spokesman said she apologised for the inconvenience to customers.
