A surprise on Sunday 30th August 2020 was BR SULZER Type 4 1Co-Co1 diesel electric D123 LEICESTERSHIRE AND DERBYSHIRE YEOMANRY heading light engine along the up line at Woodthorpe. I thought it might have being going to Quorn to relieve D8098 which I had been told was required for engineering department duties associated with bridge replacement. The next photograph dispels this idea.
