Each page is preformatted with hand written details of each Signal Cabin starting on the first page with Fosse Road Cabin belonging to Leamington Station. It continues with the stationing of the Telegraph Inspector, Telegraph Lineman, Signal Fitter, Signal Inspector. The system in use, in this case Spagnoletti, Distance to Harbury Cabin.
