We have produced in O Gauge the CDA China Clay Hoppers synonymous with the current Kernow China Clay Scene, seen working from various clay works / dries to the docks at Carne Point, Fowey.
British Rail introduced a fleet of 125 CDA hoppers to carry china clay from Kernow/Cornwall in 1987. They were built at BREL Doncaster works and based on the HAA Merry-Go-Round coal hopper wagons with the addition of a rolling roof, and associated operating mechanism, to protect the china clay being carried inside. A further batch of 15 were converted from existing HAA hoppers in 1989
The CDAs replaced a number of older designs of smaller open-end tipper ‘clayhood’ wagons. Much of the traffic was destined for export through the docks at Fowey, but also to Staffordshire (for use in pottery) and Scotland (primarily for paper mills). They have been operated by British Rail for English China Clays PLC (ECC), English, Welsh & Scottish Railway (EWS) and many continue in operation on their original duties for their current operator DB Cargo.
