Class J Tanks (Class F before 1900)

Class J Tanks (Class F before 1900)

In 1900 all of the water tanks used by the W.A.G.R. were grouped together as class J. This included some bogie and six-wheeled vehicles as well as the normal four wheelers. These have their own separate pages. The four wheelers have a very complicated history. As with the Z class brake vans I will adopt an unofficial "type" system to distinguish between the various J class tanks. As usual these are colour coded on this page.

In the early years of the W.A.G.R there were relatively few water tank wagons. The first was built in 1885 and was followed by another in 1886, one more in 1887 and a fourth in 1889. There the total stayed until 1892. These first 4 wagons were likely to have been built on 15' Metropolitan RC&WCo chassis and were probably numbers 90, 98, 141 and 142. In 1900 F90 became J4918 because there were two wagons numbered 90.

In 1892 the total doubled to 8 with another 4 the following year, not necessarily all of the same type. By 1900 there were fourteen 1312 gallon iron tanks on MRCWCo frames according to a 1903 diagram with 7 left by 1903 and none the following year. It is not clear if the tanks were scrapped or ended up on other underframes.

Type 1 - 15-0" wooden frames of the WAGR's original Metropolitan RCWCo type with 1312 gallon rectangular iron tanks. Possibly numbers

90, 98, 140, 141, 142, 176, 205, 2, 3, 4, 103

Higher numbers

1063, 1064, 1065, 1066, 1067, 1068, 1069, 1070, 1071, 1072, 1073, 1074, 1075, 1076, 1077 from where?

All of the other MRCWCo wagons were built before 1893 and numbered below 450 except for a few cases where numbers were duplicated. There were 2 wagons numbered 90 in 1900 and the tank wagon F90 became J4918.

F1068. a 1312 gallon iron tank on a MRCWCo 15' underframe. The mystery with this one and indeed the whole 1063-1077 group is why the high numbers?

The WAGR outline diagram is shown below.

Until the Goldfields' water supply scheme was completed there were several years where standard wagons from classes G and H were temporarily converted to water tanks during the summer and then re-converted during the winter. They did not always go back to the same type that they had started out as. Tanks were rectangular and made of either wood or iron.

Four J class water tanks at Midland Workshops circa 1905. Three of the four are 1312 gallon wooden tanks on the NZR chassis (type 3) whilst the other one with the prominent side stanchions has a 1390 gallon tank on the same underframe (type 4). The third tank from the left has a side discharge valve for supplying remote outposts of the W.A.G.R. (RHWA collection)

Type 2 - 14'-0" chassis with 1312 gallon wooden tanks.

In 1903 there were six 1312 wooden tanks on 14' underframes according to the diagram from this period. This total reduced to four in 1908 but there were still four in 1912.

I had thought that these might have been built on 14' ex GSR underframes. It is known that 4229, 4241, 4242, 4249, 4252, 4253, 4255, 4258, 4262 from the ex GSR number series were all J class tanks in 1900. These had all gone by 1908 being replaced by new wagons in classes D (4255) in 1905, HA (4249, 4253) also in 1905, and GC (4229, 4241, 4242, 4252, 4258, 4262) in 1908. This is obviously a problem. Only 4229 of the above should have been on a 14' chassis. More pertinently the GSR underframes had iron rather than wooden solebars and the photo at right shows a14' wagon with wooden solebars. This leaves us with conversions from some of the very early wagons and competition for the numbers listed as Type 1 above.

The WAGR outline diagram is shown below.

This 1312 wooden tank is not on a NZR type underframe or one of the 15' MRCWCo ones and the tank reaches almost to the buffer beams at each end so this must be one of the 14' long wagons.

There were a number of variations on a theme with the N.Z.R. 15'-0" underframe. Frustratingly many underframes in this group carried more than one type of tank during their lives and this makes life rather difficult for the historian.

Type 3 had a 1312 gallon wooden tank on the 15'-0" NZR underframe. This was the type that was frequently built in a hurry on G or H class wagon underframes.

Some of these wagons such as J3700 at right had the no floor or curbrails whilst the more common variant in the photo above did.

The WAGR outline diagram is shown below.

A more permanent variation on the NZR chassis had a 1312 gallon rectangular iron tank (type 4). It is possible that these rectangular tanks came from the older MRCWCo wagons as they were written off and were fitted to NZR type frames in the 1900-1909 period.

The WAGR outline diagram is shown below.

The tank in the photo at left appears to be J294. J294 had gained an iron tank by 1926.

Another group (type 5) had a 1390 gallon wooden tank on the N.Z R. underframe.

The photo shows J2845 at Midland Workshops. This is the only clear shot that I have of one of these in WAGR livery. A 1903 diagram lists 40 of this type and they may be in the series 2802-2846 which all seem to have been J class tanks in 1900. Nine of these disappeared in 1907-8

Type 7 - one odd vehicle (J77) which in 1926 acquired a 1420 gallon tank with "special joints". It is not known what chassis this wagon used but was probably a NZR type.

In 1925-6 ten of the N.Z.R. underframe wagons acquired 2025 gallon wooden tanks (type 8). The WAGR outline diagram is shown below.

Two blowups from photos in the State Library of WA collection (4336B/56 - left and 4336B/45 - right) show one of the 2025 gallon J's being used in 1929 on the construction of the Denmark-Nornalip railway. The visual give-away that this is a 2025 gallon tank is the lack of an air gap between the bottom of the tank and the underframe and the taller sides.

In 1926-1930 some NZR underframe wagons were given a rectangular 1630 gallon tank (type 9).

There were fewer variations on the GC type underframe. Fifty purpose built tankers (7847-7856) on the GC underframe (type 11) only lasted from 1911 to 1913 when they were converted to M class wagons. They are not considered here. Other variations on the GC underframe didn't appear until the 1950's when many of the older tankers were replaced by new 1600 gallon tankers on wooden GC chassis (type 12) built from 1953-5. One of these wagons (J9156) had a steel GC type underframe (type 13). There was also a single 1650 gallon wagon (J7323) on a GC underframe which had an old P class boiler barrel for the tank (type 14). These types based on the GC all have their own separate pages and so are not considered further here.

Once the steam era was over the demand for water tanks was much reduced but not eliminated. From 1968 some of the 1600 gallon tanks from older J class wagons were fitted onto CXA class chassis to produce a final group of four wheeled water tanks (type 15) used for chromate water for diesel engines. This type based on the CXA chassis has its own separate page and so is not considered further here. Known conversions from older types included 519, 1213 and 2413 (re-framed in 1973-4) but some of the other final survivors may also have had CXA frames from the 1970s. The last survivors in this group of J's were:

Type 7 - one odd vehicle (J77) which in 1926 acquired a 1420 gallon tank with "special joints". It is not known what chassis this wagon used but was probably a NZR type. In 1925-6 ten of the N.Z.R. underframe wagons acquired 2025 gallon wooden tanks (type 8). The WAGR outline diagram is shown below. Two blowups from photos in the State Library of WA collection (4336B/56 - left and 4336B/45 - right) show one of the 2025 gallon J's being used in 1929 on the construction of the Denmark-Nornalip railway. The visual give-away that this is a 2025 gallon tank is the lack of an air gap between the bottom of the tank and the underframe and the taller sides. In 1926-1930 some NZR underframe wagons were given a rectangular 1630 gallon tank (type 9). By 1926 numbers 294, 1015, 1017, 1078, 1286, 3703, 3940, 3958 had 1312 iron tanks

Once the steam era was over the demand for water tanks was much reduced but not eliminated. From 1968 some of the 1600 gallon tanks from older J class wagons were fitted onto CXA class chassis to produce a final group of four wheeled water tanks (type 15) used for chromate water for diesel engines. This type based on the CXA chassis has its own separate page and so is not considered further here. Known conversions from older types included 519, 1213 and 2413 (re-framed in 1973-4) but some of the other final survivors may also have had CXA frames from the 1970s. The last survivors in this group of J's were:
