Stockport signal boxes
The two Stockport signal boxes were to be replaced by automation. Their wiring and mechanical interlocking was well under way when Rail Track engineers realised that the Italian (Ansaldo) computer that would take over signalling was not compatible to the Westinghouse computer to the south. The signal boxes then had to be re-instated. Rail Track imported mechanical locking experts from Indian railways because it was thought there were not sufficient of them in UK. On 26 October 2008 they were fully in service and I drove from North Norfolk to photograph them. The camera I used was about 98 years old at the time. Something like the same age as the signal boxes. It produced a 4 1/4″ x 3 1/4″ negatives which I developed.
