The petition "We the undersigned petition the Prime Minister to instruct Ministers to ensure all former rail corridors are protected for use as transport corridors." To ensure countrywide protection in planning and development legislation of disused rail corridors. To provide for their re-use as rail lines should circumstances permit. To facilitate their development as 'Greenways', or transport corridors for cyclists, walkers, horse riders and wheelchair users. To extend nationally the network of successful routes which have been developed by Sustrans in conjunction with Local Authorities and other bodies, such as the Spen Valley Greenway in Kirklees, West Yorkshire.

In enlightened areas, former railway lines are being saved for the public's use as bridleways, so they can be used by non-motorised users on foot, horse and pedal cycle. However, in other areas, the local authorities have designated them for cycles only (like the part of the Ebury Way that is within Watford borough, or the Nicky Line in St Albans district) or the lines are sold cheaply to adjoining landowners. This petition seeks to have them retained, and made available for horse riders too, amongst other things.
