LMS 5MT 4-6-0 No 44796 with ? train between Mawcarse Junction and Glenfarg in the 1950s.This is on the north side of Glenfarg, heading downhill to Bridge of Earn, rather than the south side, where there would be more sun on the hills.
The signal box, cutting and field fence alignment all suggest it's near Balmanno Castle, but Glenfarg is probably more helpful for searching!
