More sections of the running plate have been replaced with new steel plate and the areas around the cylinders are being stripped down ready for these to be lifted off. The two piston rods and crossheads were split over the New Year’s break!
With the right-hand new frame plate now in position and ready for welding to the old frame, progress has been rapid on the overhaul of 506’s cylinders. These are at Bryn Engineering in Lancashire and are now nearing completion. The work has involved boring out the main piston bore and these will then have liners fitted to bring the cylinder diameter up to its original size.
