This website attempts to provide a picture of the particular telephone arrangements provided at the Dean Forest Railway. These arrangements are based on those of the Post Office around the 50s and 60s as this is the general approach for the railway.
The site also attempts to record the basic telecom techniques in use at that time.
Most pages are also available in PDF form for accurate printing onto A4 paper. A link to the PDF will be found at the bottom of each page with this facility.
