There was one clip missing, likely lost in the Seagate hard drive failure, but it wasn't all that brilliant to begin with. One evening in April/May 2008 I caught a glimpse of it doing a trial run to Whitby and back prior to the runs featured in this video which did survive.
The opening 3 still images were taken at Pickering Station on 14th April 2015, a couple of months before that Seagate Hard Drive problem I keep mentioning.
Thankfully I was able to recover them from my personal Facebook albums.
