The original TOPS code for such wagons was '''HTO'''. The exception, built to Diagram 1/149, had roller bearings and self-contained buffers with 100 out of the 1,000 also being vacuum through-piped.<ref>[[Bibliography#Books|Rowland (mainly HTV1996)]] pp. 53, App. 2, but a 4.</ref> A surplus of such wagons in the early 1980s led to their withdrawal. This coincided with a requirement for ‘new’ civil engineers ballast and spoil wagons to replace the elderly Grampus open wagons and second-hand 16-ton minerals wagons then in use. A programme was therefore put in hand to convert more than 2000 such wagons into ‘Clam’, ‘Rudd’ and ‘Tope’ wagons.<ref name=LTSV>LTSV.com (wagon class information)</ref>

The ‘Rudd’ variant involved the fitting of a new box body with drop-side doors, and also air brakes. 800 of these were converted by Marcroft Engineering of Stoke (wagon numbers DB 972000-DB 972399) and C C Crump of Connah’s Quay (wagon numbers DB 972400-DB 972799)to design ZB001A. The ‘Rudd’, which has a 21 ton capacity, was particularly long-lasting with more than 200 still in use at the start of 2008. <ref name=LTSV/> The [[TOPS code]] for the converted RUDD is '''ZBA'''.
