Here's the latest addition to my collection of Victorian Railways rollingstock:
This Victorian Railways hopper was coded "X" on delivery and was used for cement traffic, but was eventually recoded to "J". The first hoppers of this type initially carried pulverised brown coal for steam locos (coded "CK"), then bulk flour (coded "X", "FX", and "FJ"), and finally cement (coded "J"). At the end of their life, some were used to carry dry locomotive sand.
The pipes were for pneumatic discharge of the cement into road tankers or storage silos.
