Class KA open wagons

WAGR Official photo of three of the last 4 KAs of the 1941 batch when new. RHWA collection

In 1939 the first of a new class of open wagons entered service. They were similar in design concept to the GS class built from 1935 but with a much larger volume as these new wagons were 18'-0" long with 4'-0" high sides. The relationship between these types was akin to that between the G and GA.  It is unclear why this class was put in the "K" group rather than the "G" group especially as many of the "G" codes were never used. The WAGR outline diagram is shown below.

A total of one hundred and fourteen were built as follows:

1939 2010, 2026, 2350, 2356, 2361, 2363, 2368, 2370, 2399, 2432, 2436, 2451, 2489, 2493, 2502, 2505, 2506, 2512, 2514, 2516, 2526, 2528, 2533, 2542, 2546, 2569, 2589 built W.A.G.R.
1940 1517, 2591, 2603, 2616, 2625, 2629, 2649, 2659, 2677, 2687, 2732, 2740, 2749, 2753, 2760, 2809, 2822, 3025, 3027, 3032, 3077, 3082, 3084, 3089, 3145, 3157, 3161, 3662, 3669 built W.A.G.R.
1941 3670, 3682, 3692, 3698, 3719, 3726, 3731, 3738, 3750, 3758, 3806, 3807, 3822, 3835, 3863, 3869, 3921, 4137, 4139, 4178, 4179, 4180, 4199, 4217, 4221, 4225, 4227, 4303, 4304, 4309, 4320, 4438, 4519, 4521, 4523, 4525, 4526, 4528, 4534, 4552, 4553, 4554, 4597, 4920, 5158, 5808, 5837, 6734, 6840, 6861, 7086, 7252, 7591, 7951, 8697, 9177, 9181, 9257 built W.A.G.R.

These wagons must have been successful as the class remained intact until 1972 when writing off started. They were disposed of as follows:

The success of the KA class must have influenced the choice of a new 18'-0" chassis as the post-war standard. It is therefore even more surprising to find that in 1959 production of the KA class was restarted after a gap of eighteen years! The two hundred new wagons (19101-19159 built 1959, 19160-19300 built 1960) differed slightly from the originals in that they were fitted with end doors. It is unclear why they were built given the availability of the GM class design of similar size.

Cane support brackets were fitted to the class from 1963. They were disposed of as follows:
