Bob platform

Bob platform and end of the beam on the Elsecar pumping engine of 1795. This is the only Newcomen engine in the world that survives in its original enginehouse. It was subject to a major conservation project which was completed in 2014 and the engine can now be seen moving using hydraulic drive. The cylinder base was badly cracked after the engine was run in the 1950s with steam of too high a pressure and significant quantities of water in the bottom of the cylinder.
