This signal box was at Spalding station on the railway line from Peterborough to Lincoln and Doncaster and till it closed the line to Boston. This slide was taken from the long footbridge just to the north of the station.

This signal box was on the railway line from Peterborough to Sleaford and Lincoln on the Great Nothern loop as it is called today.

 

Much work has gone into upgrading this line. This has meant that nearly all the old signal boxes and signals and hand worked crossing gates have all gone. These have been replaced by a new signal center at Lincoln, which is to be replaced, when the York signal Center goes on line.
