Central line Tube trains to the Olympic Park have been suspended this morning.

Passengers were told at around 7am that all services were terminating at Liverpool Street due to an incident at Leyton.

A defective train westbound was awaiting the arrival of the London Fire Brigade, a train driver said.

Station announcers at Bank said there were reports of a fire on board the train.

The fire alert meant there were no Central line services between Liverpool Street and Woodford/Newbury Park, including Stratford, and there were severe delays on the rest of the line.

Early-morning travellers on the Tube were being advised to take the District or Jubilee lines instead.

To add to the Olympic travel problems, rail services in and out of Liverpool Street main line station were disrupted due to an overhead wire problem between Elsenham and Stansted Mountfitchet in Essex.

This was affecting travellers on services run by the Greater Anglia and CrossCountry train companies.
