Hello there.
If I may I would like to give a few suggestions.
Could you create a website to make your plans more readily available to the general public?
Have you considered writing to a local newspaper, and also writing to a UK wide railway magazine? My suggestion magazine wise would be either The Raiwlay Magazine or RAIL. Maybe both. This way you may gaint the support of some quite influential people who have a knowledge and interest in railways.
Hope that helped.
