I have pinched this from the Yorkshire Wolds Railway website, it is footage of the Wharram quarrying operations with some brief glimpses of the M&D.

It is worth taking a look at the YWR website thread as there are some other clips of Nunnington Station (between Gilling & Helmsley) which are interesting.
