A look at the iconic and important pilot scheme diesel locos.

Colin Alexander has been a railway enthusiast for more than thirty years and volunteered on preserved Deltic locomotives. He was born in Northumberland, and has a life-long passion for local history, sparked by his mother's copy of The King's England - Northumberland. Appreciative of the county's unique place geographically and historically, he has explored most of its once-inhabited hilltops and its medieval castles, and walked the length of its greatest defensive monument - Hadrian's Wall. He lives in Whitley Bay.
