I do know that Jackie (West Clare) applied for several grants to develop Moyasta further. The waste ground upon which the ITG equipment currently lies would have been developed as a railway museum, and a couple of proper West Clare carriages would have been built. Major upgrades to the station building would have been also required.
I saw the grant application, which was professionally prepared for Jackie.
Unfortunately, though, it was ultimately unsuccessful.
These grants can be given to voluntary bodies too. Private individuals won't have any luck, and businesses have a whole pile more hurdles to jump. In order to access these grants - most of them anyway - a properly run body like a preservation society or some other type of heritage body with a committee, constitution, etc., is usually necessary.
As an aside, possibly uniquely, in Ireland - several of the heritage-type railway schemes are privately owned by one (or maybe two) individuals. While this does not officially bar them from grants, as such, it makes eligibility more difficult. I've had personal experience of preparing applications for a number of projects. One - relating to Downpatrick some 25 years ago - came up aganist this issue. At the time, the DCDR was not operated as it is now, as a democratically run society with elected officers, but it was in the course of changing to that. Once this was the case, and the Downpatrick & Ardglass Rly Co (privately owned by about half a dozen founder members) had been dissolved and the assets placed in the hands of the new registered charity, Downpatrick & Co Down Railway, both local authority and other grants were instantly available.
