Is there any procedure in place that dictates what happens to redundant rails when lines are closed? I had a walk on New Wortley Recreation Ground yesterday and looked down the embankment of the old Wortley curve, and noticed that there are quite a few lengths of old bull-head rail down there. One of the lengths still seems to be in place on its sleepers. Would old track like this not normally be removed and sold for scrap or disposed of by other means? I am guessing that there are lots of examples of this around the country??
