The high pressure cylinder to the left and the low pressure on the right. Built in 1942 by the famous Vickers Armstrong Ltd in their Elswick works, Newcastle upon Tyne. It was designed to top up the accumulators in tower bridge, London Image It was the third engine added, as a precaution against bombing damage to the other engines. It is a 150 HP horizontal cross compound hydraulic pumping engine, Number SE1190SE. Power comes from one 18" high pressure and one 30" low pressure by 27" stroke cylinder. The engine drove two pumps by the piston tail rods, 750 pounds per square inch of pressure was developed which pumped up hydraulic accumulators. The accumulators stored hydraulic pressure which was released to up to eight hydraulic engines when the two 1000 ton road bascule sections were required to be raised for shipping. With modernisation in 1974 the engine was made redundant and thankfully donated to the Forncett steam museum.
