The Halesworth and Southwold railway doesn't exist although a lot of steam enthusiasts (Usually older men!) are re- building bits of it at each end and at Blythburgh. There is one 'slight' problem about joining all the bits together - the land where it once ran is now marshland on the side of the Blyth!
There was a display at Blythburgh as part of the Heritage Open Days. So I went to have a look.
