This class is another mixed bag group of wagons. It was created in 1954 to cover the low sided and flat wagons used as workmen's wagons. At least one of the (977 opposite); acquired a van type structure mounted in a semi-permanent way on the floor. In this case the original ends remained in place although the sides were removed. I do not know to what extent these wagons were modified from their original condition when they became HW but it seems likely that they were all different.           The photo to the right shows HW977. It seems to have lost its sides and acquired a semi-permanent van body belonging to the Signal and Telegraph engineers.

The types left covered by this page are: 1. One (NZR type) wagon converted from class H recorded as "with breakdown crane". I don't know whether this means it had a crane itself or if it was part of the breakdown train consist (which seems more likely). 2. Twelve other wagons on NZR type chassis converted from classes G and H. 3. Three wagons converted from class GA 4. One wagon converted from class GC 5. Two ex MRWA I class ballast wagons.
