Trains in and out of Norwich have been subject to delays and cancellations this morning because of signalling problems.

Some earlier Greater Anglia services between Norwich and Lowestoft and Norwich and Great Yarmouth were cancelled and there have been delays of ten minutes on the Norwich to London Liverpool Street Line.

The 8.17am Great Yarmouth to Norwich train, which was due to arrive in the city at 8.50am has also been cancelled.
