A working which I unfortunately got very few photos of, and even then usually in dismal light, was the Saturdays only 6B20 10:20 Akeman Street to Bletchley UKF fertiliser empties. Pictured here in customary weather conditions on 13 July 1991, 47237 has just passed through the long closed Swanbourne station (now a private residence). There is no chance to improve on my small collection of pictures of this train, as the fertiliser depot closed shortly afterwards and the line is now disused, with the track towards Bletchley lifted from a point just a few yards further on from this picture.
