I recently visited this museum - its a joy with great big quarrying machines scattered around the sites plus a few items of rail interest and an operational narrow gauge railway which they are extending. Only had a couple of hours and there was still plenty to see - looking forward to another visit in 2020. Attached is a selection of photos.
Threlkeld is one of those places high up on my must see list. There has been several articles about it in the Old Glory magazine, they hold rallies and demos, it would be nice if I could get my old Lister an invite! Thanks for the excellent photos mate. Cheer's, Pete.
