Hullo Michael,

Both tunnels are used by Bats for roosting. As an 'endangered species' they are so highly protected that I can't see the tunnels ever being used for anything again.

Here's an example of how seriously this is taken...

A quarrying company, in Derbyshire I think, has agreed to re-route one of Network Rails lines around a hill that it currently tunnels through. The hill will then be quarried away. Upon the diversion opening the existing tunnel will instantly be sealed up to keep Bats out for, if they roosted the whole multi-million pound scheme would have to be abandoned.

I wonder how many property owners kill Bats to ensure they're not afflicted by these stringent regulations? I suspect a very great many.

Best - Ian
