The line was designated 'Out of Use (temporary)' beyond milepost 0 mi 30 ch in mid 2013 following Hanson UK mothballing the quarry. I was chatting with somebody on another group who actually works in the Yate Middle signal box and he has so say been told that Hanson UK have approached NR to ask how quickly they could get trains running again? This was further confirmed by someone else who used to work the line and went to a reunion of sorts where it was mentioned also. Does anyone know anything? I have always had an interest in this line, partially because i actually live next to Grovesend Tunnel which used to carry the line to Thornbury.
