56049 passes Black Bank (between Ely and March) with a short rake of Redland stone empties on 20 May 1991. According to the 1902 Ordnance Survey 25 inch map, the buffer stop on the left marks the end of a refuge siding, not as I first suspected a headshunt for the goods yard at Black Bank station, which was situated by the level crossing that can just be seen in the distance.
