Originally TOPS numbered from 47001 to 47298, these locomotives were the "basic" Class 47 with steam heating equipment fitted.
 In the 1970s and 1980s, with steam heating of trains gradually being phased out, all locomotives fitted with the equipment gradually had their steam heating boilers removed.
 Some were fitted with ETH and became 47/4s, whilst the others remained with no train heating capability and were therefore used mainly on freight work.
In the 1990s, the class designation 47/2 was applied to some class 47/0s and class 47/3s after they were fitted with multiple working equipment.
 The locomotives involved also had their vacuum braking systems removed or isolated, leaving them air braked only.
This was mainly a paper exercise, however, and the locomotives were not renumbered; in this article they are included in Class 47/0.
