transport route. Greenways are not mentioned in the RPGs, though the development of suitable long-distance walking and cycling routes (subject to environmental assessment) are supported. It is not the purpose of the Regional Planning Guidelines to see such routes provided at the expense of long-term strategic infrastructure so it is critical that the goals are not hampered even in the short term particularly when other more suitable greenway options could be explored taking account of environmental, social and economic considerations". Supporters of the greenway state that use of a greenway will protect the trackbed from adverse possession claims and will not preclude reinstatement of the disused sections of line as a working railway in the future. Sligo to Derry The idea for the development of a North-Western Rail Corridor is the suggested construction of a railway connecting Sligo, Bundoran, Ballyshannon, Donegal Town, Letterkenny and Derry, where it would connect with the Belfast-Derry railway line. This proposal, however, is not included in the TEN-T European Transport policy. However, a study on future rail lines commissioned by Iarnród Éireann, by consultants AECOM, in 2011 found that an extension of the Belfast-Derry railway line to Letterkenny was one point away from being regarded as a viable prospect.
