I was so surprised to see anything stabled in Truro Yard that I thought I would send you the photo even though it's just a Rail Grinder.
DR79273 and DR79263 had journeyed 6U03 from Par arriving at 04.09 on 1st August.
Many thanks for this picture Chris. Nice to hear from you, same surname but no relation. Also thanks for the extra detail - it adds value.
