This album contains 12 photos of steam-hauled freights working on the SMJ in January 1964 and February 1965. As you can see, the weather ranged from freezing fog to just freezing and overcast! In fact I have only included the poor-quality 1964 photos because they show a BR 5MT 4-6-0 which I believe was a fairly rare sight on the SMJ.
All the other photos were taken on a Saturday in February 1965 and although the locos were filthy and the weather grotty, they do give a reasonable picture of the latter day steam workings on the SMJ.
