Agecroft No 1 was one of three locomotives built in 1948 in Newcastle to shunt wagons at Agecroft Power Station. It remained in service until 1980 when it passed into private ownership. It was bought by the Science Museum at Manchester in 2009 and is now at the National railway Museum in York.
On the day I visited it was hauling a brake van, giving rides to visitors.
So often we concentrate on the big passenger express locomotives but there were hundreds, if not thousands, of engines, like Agecroft that drove our industry during the steam era and are part of that history.
