The train line running between Norwich and Lowestoft has reopened.
The track was badly damaged by floodwater at Haddiscoe on Sunday 30 January.
Video footage shows flood waters gushing under a damaged section of train line, leaving tracks suspended in mid-air, only metres from a passenger service which came to a stop just in time.
The embankment and the stones that support the track were washed away due to a combination of high tides and winds.
Six passengers had to be rescued from the train although no one was injured.
Extensive repair work has now taken place to get the line running again.
A Greater Anglia spokesperson said: "We would like to thank customers for their patience this week while the work has been carried out. Rail replacement buses will continue to run until the line reopens so passengers can complete their journeys."
A bus replacement service has been running for passengers in the meantime.
