Semi at Leeds
 

I recently watched a DVD of railways in the West Riding centered on Leeds from 1963-1967. I was surprised to see a Coronation on the turnig triange no 46255 City of Hereford. It was on a Stephenson Loco Society special from Carlisle to Leeds. Living at York I was a regular visitor to Leeds ans its sheds
but I never heard of a semi at Leeds before. Can any other enthusiast remember seeing one there?
