Just a simple question how long is the longest that rolling stock has been left sittings in sidings for without use but at the same time not been scrapped? Some of the ones I can think of are Oakamoor Sand Sidings where some of the items rolling stock have been there since at least 1988 although the line is not owned by BR/NR any more. Longport there are 2 liquid containers that have been there since at least 1999. Kingsbury Warwickshire, there are many wagons that I think have been there since 1989 although they may have been there longer. I am sure you can think of more.
