Class JK water tanks

In 1927 a new class of all steel open wagon appeared in Western Australia. It was given the redundant K class code previously used for ballast wagons. A total of 375 wagons of this type were constructed in 1927/8.

In 1936 K class wagons formed the basis for the JK class tankers. In this conversion the doors were plated over and a wooden roof fitted. This class existed for some time and conversions to and from JK are as listed below. In the early years the same wagons seem to have been involved each time and it may be that they ran as class K with sealed sides and no doors. From 1951 such wagons were classified KC (again) and used for coal traffic. Many former K class wagons were converted from JK to KC rather than back to class K. Only five wagons were written off as class JK (in 1950) and the rest were all reconverted for other uses.

The two photos show how the JK class wagons written off in 1950 met their fate.
