Dinnington North signalbox courtesy of Chris Booth, Worksop PSB.
It was situated on the South Side of Rotherham Lane Bridge on the Laughton to Thurcroft Road.
As you will see from Dinnington Jn signalbox page, in which the line to Thurcroft Colliery and onto Aldwarke is situated, I have no knowledge of which signalbox actually controlled this branch, maybe someone could pass on some information. I'll have to research this one!!
