Work on 401s valves

During maintenance, it was discovered that some of the valve rings on the lead RHS piston valve head were damaged, with one missing altogether. It was decided to remove the spindle, clean, inspect and replace. We, fortunately, had a set of valve and piston rings made when we first got 401 so we changed the full set. After a bit of head-scratching and choice language, the valve was fitted. The LHS valve will be inspected next winter
