There is a bit of discussion on the GBIX thread concerning 44871's return to Crewe to have a broken radius rod replaced, but I think here is a more appropriate place for my question. The picture at http://www.national-preservation.com/attachments/dsc_5313-44871-failure-mill-meece-250416-jpg.19692/ shows the loco apparently still in light steam. I understand that it is desirable to have a bit of steam flowing through the cylinders to carry some oil with it. But what happens when the valve gear is out of action? The picture shows the combination lever also disconnected from the crosshead, so presumably the valve on that side is temporarily fixed in position, with the inlet ports open to one end of the cylinder and the exhaust ports open to the other end. What do you do to keep some lubrication to the cylinder, and how do you avoid particles from ther smokebox being drawn into the cylinder?
