I was on this working last Saturday morning, the 6th of March. It went to NAW as 6Z20, loaded, and then went to Crewe Basford Hall as 6Z21. I'm not sure what the stone is being used for. Basford Hall as a destination suggests an engineering job, but the stone we haul out of NAW is too fine to be used as ballast. Perhaps someone else can shed some light on where it's ultimately going and what it's being used for?
