With thanks to a member of the Avon Valley Railway group who passed on this photo via Bob Edwardes.
Believed to have been taken by Rex Coffin in around 1952 (judging by the fact that Crane 32 looks brand new) it shows 5700 class pannier tank No. 7790 at the head of a train of loaded conflats on the quayside line.
The loco is still in faded G W R livery and has a GW shunters’ truck attached to the front.
On the extreme right of the photo it looks as though a road wagon is parked across what is now the main running line.
In the background to the left can be seen the crane whose pedestal still stands at the edge of Lloyds Amphitheatre.
