I believe it's one of the early units BR wre trying out, sat in platform 3 at Plymouth. It was taken about 17.00hrs, Friday 10th May 1985 as I waited to board F&Ws Skirl o'the Pipes 6.
Cheers, Dave Anthony Many thanks Dave - one of the Class 140's brought down on trial on the Gunnislake branch I believe - why they ever pushed ahead (or was it backward!) and punished us with the 142's on that branch we'll never know?
