This group of forty wagons (4515-4554) was unusual in that they carried both minerals and water.

They were built in 1897 by James Martin and Co for the Water Trust Mining Co. They were originally intended for transporting gold ore to the Seabrook battery (hence the name) for processing.

Before this scheme was actually put in place the Government decided to build the Goldfields Water Supply pipeline and therefore it was no longer necessary to move the ore to where water was plentiful for processing.

The wagons were emptied via side doors along the full length of the wagon. To assist in this the centre of the wagon contained V shaped hump along the centre of the wagon. Under the hump was the space for carrying water. In 1899 the tanks were removed and they were sent to the Yilgarn district for firewood traffic.

Most went on to a second career as "Jetty stock" once the depression started and they were no longer needed on the main line.

These wagons lasted well into the 1950's as JETTY stock. Many were used as Ash Wagons for which purpose they would seem to be ideal. The last survivor in Jetty stock seems to have been 4540 (JETTY 9) which at least on paper was not scrapped until 1974!

The WAGR official image at left from the RHWA collection shows one of the Seabrook wagons behind an I class bolster wagon inside the wagon shop at Midland Junction workshops in around 1905. You can just about make out a line across the end showing the shape of the tank inside.
