Seriously good trip! 😉 Been on my hit list for a long time. Many IA relics which means you can interpret how it was worked - on the cheap with mixed rail types, even in the same panel where one side was bar rail, the other tee bar or bridge! Plus some mysteries to solve where what's present doesn't match official plans. Return visits required needing SRT and some bolting to solve these mysteries.
The BFf miners must all have lived on Dundee marmalade - even here remains of pottery pots!
