What is a CargoSprinter?

This is a small container transporter currently used by CRT in Oz, which is based I think out of Albury in NSW. However the prototype is used in Europe and Britain for various things such as PER work, container transport, emergency vehicles, etc. Marklin used to produce a set but it can be quite expensive on the second hand market. I think the CargoSprinter would be easy to scratchbuild (famous last words) as it is basically five container wagons joined together. The end wagons have driving cabins which could hide a SPUD each. Each cabin is fairly angular so I reckon styrene would be the go. A bit more research on dimensions required and if anybody reading this can help out that would be great.
