Sitting in the back of the former Pontop & Jarrow Railway engine shed, at Marley Hill, on the Tanfield Railway, Sir Cecil A. Cochrane, the engine in this photo, is moving towards the final stages of a retube and ‘light’ overhaul. (She’s back at work now). No, your eyes are not decieving you, the boiler cladding is made of wood. First a wooden frame is made by cutting, soaking, and bending, pieces of timber to the shape of the barrel the wooden lagging strips are then attached to these frames, which is what you see here. The ‘finer’ details of the process of re-cladding were explained to me by Ian Cowan, the chap you see about to climb onto the footplate, with a small strip of wood which was being fitted to the cladding inside the cab – joinery and boiler making skills required!
I had no idea, until I saw this work being undertaken, that this was a method of boiler cladding for these enines – you do, as they say, ‘learn summat new every day’. When Marley Hill shed was part of a working colliery railway system this kind of work, retubing, and light general repairs, would have been a commonplace. Behind the white wall to the left of the picture, is a fully operational forge which would have allowed more substantial repairs to be carried out. And, from time to time during the year, volunteers operate the forge, to give visitors a taste of what was involved.
Should you wish you can see a photo of the volunteers using the the forge, one can be found in the steamagedaydreams archive for September 2015 – ‘A little forgery’.
