A bit short for a TSW route (9.2 miles) but big isn't always better. This route is a branchline in Derbyshire and maybe just maybe be an extension from Ambergate to Duffield and a small branchline to Wirksworth. This route is preserved now. Stopping at Duffield, Hazelfeild, Shottle, Idridgehay and Wirksworth ; maybe at belper for Peak forest. Loco Fowler 3F Jinty Layors Fowler 4F for the branch and for PFR extension 8F and Jubilee for PFR extension
