Central Line trains are being modified

Services on the western section between Ealing Broadway and Marble Arch resumed shortly after 1530 GMT.

They will run at 10 minute intervals but West Acton and Queensway stations remain closed.

London Underground (LU) had already begun a limited service between Woodford and Bethnal Green on the eastern part of the line.

LU said it hopes to have the whole line running by Easter, after services were suspended when a train derailed at Chancery Lane in January injuring 32 people.

More than 80 trains have had to be modified to make the Central Line safe.

Alternative routes

At present there are still no trains running through the line's busiest area in the heart of London - a section that includes Bond Street, Oxford Circus and Tottenham Court Road stations.

As a result, LU is advising commuters to use alternative routes.

Paul Godier, LU's managing director, said: "We know the situation has caused frustration among Tube travellers, but we hope they appreciate our commitment to making sure the line is safe."

The line is the longest on the Tube network, stretching from West Ruislip in west London to Epping in Essex.
