Class 31, unidentified down working on down fast, Blatchbridge Junction
Class 31, unidentified down working on down fast, Blatchbridge Junction 
 Unfortunately, my records have let me down and I have no details as to what this class 31 is and what working it was on. I do know that it is taken at a foot crossing at Blatchbridge Junction just outside Frome. Indeed, the Frome line can be seen curving off to the left behind the redundant track panels. Normally, a 31 in this area would be on a Bristol to Weymouth working however as this 31 is on the Frome avoiding line therefore not stopping at the Somerset town, so, I知 not so sure?
