A trespass incident and concern over a piece of newly-laid track have caused some delays on the Norwich to London railway line this morning.
A spokesman for train operator Great Anglia said the two small and unrelated problems caused slight delays for commuters earlier today.
They said the section of track at Ipswich tunnel was now being monitored by Network Rail.
'There was some concern over a piece of track which has been recently relaid,' they added. 'If there is any concern in this sort of situation it's reported to Netwrok Rail and they send someone down to monitor the state of it.
'Trains are currently running over that section of track, but at a slightly slower speed.'
The trespass incident happened at Chelmsford, and services were suspended for a short period of time, but when personnel were sent to investigate the person had disappeared.
