My attention has been drawn to a parliamentary petition which seeks protection of former railway track beds from development so that they could be reused at some point in the future with a particular aim of rural regeneration.
The link below allows you to sign.
https://petition.parliament.uk/petitions/105077
The closing date for signing the petition is January 28th 2016. If 10,000 signatures are received it will elicit a response from the Government and 100,000 signatures will ensure a debate.
