Clams and Rudds were both introduced in 1989 for ballast, spoil and sleepers. They had new bodies on underframes reclaimed from hopper wagons. They differed in that the Clams had fixed sides and ends and retained vacuum brake whereas the Rudds were similar to the older Tunny with 3 drop doors in the side but had air braking. NOTE – Some of these photographs are low quality scans (they have an [m] suffix) and may not print well. Do not order larger prints.
