Great Central Railway signalling – Tom Ingall

On 28th March Tom Ingall presented a fascinating talk about the development of the signalling on the GCR over the last 50 years. He explained in animated diagrams the fundamentals of signalling with emphasis on this unique heritage railway which has both double and single running lines, hence utilises both absolute block and token working.

He then went on to describe in detail the four signal boxes on the line today, their background and their present day operational functions. An entertaining, informative and most enjoyable talk
