Gn15 is a growing underground movement and more popular than those who model in the popular scales imagine.
Listed below, in no particular order, are links to sites that I have found helpful or inspirational. Each link opens a new window.

Kirklees Light Railway - The site of this Yorkshire based system.
Rhyl Miniature Railway - Pleasure Line in North Wales.
Cleethorpes Coast Light Railway - A very tidy line in this traditional holiday resort.
