Durham's 1469 working for Stockton today on X12 on the 0950 Durham-Middlesbrough, albeit running very late. It replaced 1457 which broke down somewhere up that way. It was replaced itself in Middlesbrough in order to send the 1105 one out on time. Didn't get used the rest of the day as far as I'm aware (it has Durham's screens in anyway...). Whether it's gone back to Durham I don't know.
