After working a few test trains during 2004, 37003 finally entered passenger service on the Wensleydale Railway on 14 May 2005. It seen here passing Mudfields Farm, Crakehall, with its inaugural run - the 16:45 Leeming Bar to Redmire. The loco looks great in its BR blue livery (which would have looked even better in the sun that was out just before the train came), but I'm not too sure about the brilliant red livery of the coaches!
