GWR Goods Rolling Stock

A shunting layout wouldn't be much good without any goods wagons or vans to actually shunt, so I've been steadily adding some assorted rolling stock to the set up. These include half a dozen GWR vans by Mainline and Bachmann, so I have enough to be starting with. I do need some open wagons, flat wagons and cattle trucks, however, as well as more early British Railways goods stock for the NE Region project. I'd really like a rake of three or four private owner tank wagons too assuming they fit in with the layout theme.
