Hi Ian & Vikki.
I'm no expert, but I think this might be useful.
If it formerly belonged to British Railways, and has not been sold off it will be covered by Highways Agency Historical Railways Estate (this used to be called British Railways Board (Residuary) Ltd.), who can be contacted at the following:
Highways Agency Historical Railways Estate
Hudson House
Toft Green
York, YO1 6HP
Tel: 0300 123 5000
Email:

If it still belongs to the Coal Board, I'm not sure but this might be the best contact:
The Coal Authority,
200 Lichfield Lane,
Mansfield,
Nottinghamshire
NG18 4RG
[email protected]
I hope you can get this resolved.
Tony
