After getting back to Frome from Bath the weather picked
up a little. I decided to take a walk into town from my mum's house to see this light engine movement that I had been tracking. 66621 is seen passing through Frome on the line to Whatley from the town's tiny Sheppard (sic) bridge. Running as 6V18 I believe that it had run as a light engine all the way from Allington Aggregates in the Medway valley unless anybody can advise me otherwise!
