Mill Green signal box is in Spalding and has a level crossing which are now lifting barriers. The box is to the north of Spalding station.

This signal box closed in 2014.  In May 2014 Network Rail men were working all around it. I had wait while they got some thing from there van, so as I did not get any one in the photos.

The Great Northern Railway loop from Peterborough to Doncaster by Lincoln is now controled from the Lincoln signal centre. When the new York signal centre opens, the Lincoln Signal centre will all so close and York will take over all of the GNR loop.
