Carmarthen–Aberystwyth Line
Looking for possible privately-funded rail projects, I have come across the Carmarthen–Aberystwyth Line on Wikipedia.
This is said on Wikipedia under Reopening.
Official talks of reopening started in 2014, when First Minister Carwyn Jones shared his support towards the reopening, and it was adopted as an official policy of the Welsh Liberal Democrats. The next two years were followed by support from Carmarthenshire County Council, Ceredigion County Council, the Minister for Science, Economy and Transport (Welsh Government) and Plaid Cymru. Official talks and meeting included Stephen Crabb MP, Secretary of State for Wales and James Price, Director General, Economy, Science and Transport (Welsh Government) shortly followed by the AECOM report. There have been several support, funding and help pledges.
In October 2016, the Welsh government announced it would be allocating £300,000 towards funding a feasibility report into re-opening the railway as part of the draft 2017-18 budget. The study is being carried out by engineering consultancy Mott MacDonald and began in September 2017.
Reopening would certainly open up an area with no railways.
