To further this thread, i remember the Evening Mail doing a pull-out supplement on Snow Hill Station, i think it was about the same time as the tunnel walk. The supplement mentioned that Snow Hill tunnel was haunted by the ghost of a shunter driver called Billy Richards. He was killed in the tunnel when a light engine hit him. It was said that some folk had seen an image of a man walking out of the tunnel on several occasions dressed in a 30s railway uniform during the night time. Has anyone else heard about this ?
