I don't know if this is the right location but The first Locomotive built for the Italian railways was built at Bedlington iron works (though the Italians say it was built at Newcastle) the loco is on display at the railway museum in Naples and guess what the loco is called Longridge. As Robert Stevenson spent that much time away building railways all over the world Mr. Longridge ran both the works at Bedlington and Newcastle. Hope this info helps.
