Has anyone mentioned the "Back Line" on the ex-GN via Gedling - premature closure at the beginning of 1960 due to the state of Mapperley Tunnel?
We should remember the five people who died. They were occupants of houses in Temple Drive, Swinton which instantly collapsed into the sealed shaft when the shaft fill fell into the tunnel. The inquiry determined that the construction formwork had been left in place above the tunnel crown, supporting the brick lining of the shaft, when the tunnel was built in 1849/50. In 1953, after over a hundred years of deterioration, the timberwork suddenly failed and the whole weight of the shaft and its fill came down on the tunnel crown, collapsing it into the tunnel. There is still a gap in the houses in Temple Drive.Patricroft-Clifton Junction closed after Clifton Hall (‘Black Harry’) Tunnel collapsed.
A surefire (sorry about the pun) candidate for the 'Darwin Awards' had they been going then. Rather like a bloke up my street when I was a kid, who tried to get rid of a stale chunk of bread by flushing it down the khazi. Not surprisingly, it swelled up in the wet sewer and blocked it.“Readers Digest” version: signalman was getting rid of old armchair, decided to get it smouldering and kick it downstairs but couldn’t get it out the door…..
In mitigation, I was told that the door of the box had been replaced at some point by one that was narrower than it was when the chair was first brought there.A surefire (sorry about the pun) candidate for the 'Darwin Awards' had they been going then.

Is it true to say that ever since that accident, new housing has not been permitted to be built over "old " tunnels? I know of two examples: Hooley Hill tunnel(LNWR,Guide Bridge avoiding line) in Audenshaw, where there are unexpected gaps in the housing , mostly built in 1980s and Disley Tunnel near High Lane, Bow Fell Drive where land between 60's(?) housing is still owned by the Railway , immediately over the tunnel.We should remember the five people who died.
