No.4 Boiler

In business for the first time in preservation was the No.4 boiler at the Claymills pumping station. This Lancashire boiler, complete with automatic stoker, proved to be a rather better steamer than No.5 (beyond) which is close to the end of its 10 year ticket. This caused some embarassment for the boilerman as the safety valve lifted and filled the house with steam for a while.
