//How long did it take you to google that one N/J.//
I didn't Google it. I am a railway enthusiast ("anorak" you'd probably call it) and I am a member of the Deltic Preservation Society. The Society has custody of three of the six preserved production Deltic locomotives (out of the 22 built). The 22 were allocated to three depots, 6 to Gateshead and 8 each to Finsbury Park (London) and Haymarket (Edinburgh). They provided the motive power for most of the "top link" express services from London Kings Cross to the north of England and to Scotland from 1962 until they were relegated to secondary services in the late 1970s.
I thought everybody had heard of "The Gateshead Games".
