JA Class water tankers, JP class petrol tankers, JX class Bitumen tankers

The second class to use the JA classification were a group of 2800 gallon water tankers built on the GC type chassis. The total of eighty-one wagons was constructed as follows:

1925 - 10289-10308

1928 - 10976-10983, 11104-11108

1929 - 1509, 2667, 3723, 11109-11128

1930 - 1089, 1448, 1952, 2605, 3079

1934 - 3794, 3847, 3861, 4152, 4160, 4194, 4355, 4522, 8377, 9346

1936 - 613, 620, 631, 632, 636, 638, 644, 649, 655, 668

During this period some of these wagons were hired out to the oil companies and used to transport petrol. For this traffic they were fitted with a special manhole cover and reclassified JP. The wagons involved were:

1927 10290, 10295, 10299, 10300, 10301, 10308 to JP (VACUUM)
1928 10293, 10297, 10977, 10979, 10983 to JP (SHELL)
1929 11121-4, 11126 to JP (VACUUM)
1930 10290, 10295, 10299, 10300, 10301, 10308, 11121-4, 11126 ex JP
1931 10293, 10297, 10977, 10979, 10983 ex JP

From 1933 numbers 10300, 11104, 11112 and 11117 were used as poison tanks for the weed-killing train. Wagons known to have been used at some time for this traffic also include 1509, 2667, 10290, 10300, 10306, 10307, 10977, 10978, 10980, 10982, 11104, 11107, 11111, 11112, 11114, 11117, 11121, 11126. From 1935 to 1938 numbers 10299 and 10308 were used as residual oil tankers whilst 11119 was used as a rail washer.

In 1937 a variant on the JA design appeared when the final batch of ten wagons were turned out with all steel underframes. They were numbered 672, 674, 682, 699, 1254, 1404, 1457, 1485, 1491, 1582. Another group of conversions started in 1939 when two wagons were converted to bitumen tankers and reclassified JX. The conversions and fate of the JX's were as follows:

1939

655, 10976 to JX

1485, 1491 to JX (steel frames)

1956

2605, 10298, 10303, 10978, 11127 to JX

1457 to JX (steel frames)

1957

As steam declined the requirement for water tankers fell and so the JA's were withdrawn. Withdrawal of the remaining JA class wagons was as follows:
