Thanks, Col. Your information confirms that I've mixed up the sequence of photos I took on the trip.
The train visited Bridlington, Filey (got a couple of shots from there but haven't scanned them, yet) and Scarborough (not into the station, though), then up the coast line through Robin Hood's Bay and reversed down to Whitby Town station. Then back via Pickering.
Whilst looking through the box with the slide, which my sister recovered from our old house in Oldham, I found three odd B&W prints - rather poor I have to admit. Here they are.
First, BR Standard Caprotti Class 5, No. 73130. I can't say I remember taking this. I have no idea of the location although the building in the background is quite distinctive. Perhaps someone will recognise it. Miles Platting area, perhaps?
Next, a Metro-Vic Co-Bo, D5702, leaving Manchester Victoria in the general direction of Red Bank Sidings.
Finally, a Birmingham Type 2 (I think) in the north end bay platforms at Carlisle Citadel, with what looks like an ex-LMS Class 4 next to it.
Unless I find the bulk of my B&W prints, I think that's it from that era. The colour slides I've got are mainly blue diesels and preservation era steam - both main line and preserved railways.
Dave.
