This signal box replaced the original box here that was built in 1882. This box dates to 1957. This box was closed in 2014, when the Sleaford avoiding line reopened and then this part of the line came under the control of the Lincoln signal center.

Sleaford South signal box from across a lake ( pond ) in November 2004 on the GN&GEJR From Peterborough To Lincoln. It controled the southern junction to the Sleaford avoiding line. It was a little difficult to get near as there is a lake one side and bushes and trees have now grown up around it. It like many boxes today had new PVC windows.

This signal box was on the railway line from Peterborough to Spalding  Sleaford and Lincoln and Doncaster 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, replaced by barriers. These are controled by a new signal center at Lincoln, which is to be replaced, when the York signal Center goes on line by the one at York.

Sleaford station is on the Nottingham to Boston and Skegness line.Passenger trains on the railway line from Peterborough to Spalding  Sleaford and Lincoln and Doncaster on the Great Nothern loop use Sleaford station turning off the GN&GER line at Sleaford South Juction and return at Sleaford North Juction. The Direct line between the south and North juction was closed for many years but is now reopened.
