Trains have been disrupted between Diss and Stowmarket this morning after a lorry hit a bridge at Haughley.
A Greater Anglia spokeswoman said that the lorry struck the railway bridge at Bacton Lane at 9.03am.
She said: “The service has been delayed by 30 minutes but there are no cancellations.”
Police also attended the scene.
A spokeswoman said a Mercedes heavy goods vehicle had struck the bridge and couldn’t reverse out.
The lorry had been moved by 9.50am and the road was reopened.
A spokeswoman for Network Rail said engineers have attended the scene to assess whether any damage has been caused to the track.
She said: “After the initial impact trains were put to a stop before being run at a slower line speed. Normal line speed resumed shortly after.
“The bridge has now been examined by engineers. There has been some superficial damage to the bridge but nothing major has been reported.”
