As sad as it sounds, about one or two weekends a month I'm covered in muck and grime and doing work on (read: beating the shit out of) preserved diesel and steam locomotives over in Preston. Workshop volunteer at Ribble Steam Railway Not done much with the kettles yet, those are the remit of the old boys (and I still have trouble getting to grips with how they work), so mostly my legs are sticking out of the engine bay of a diesel shunter. Also done work on rolling stock and the like, whatever needs a hand really. Good fun, and surprised at the fact theres more than a few of a similar age to me.
