It is a model of a 40' canvas covered open top container. AWM SZ 40ft open top Container MSC. While I have not seen one on the Adelaide Melbourne corridor, in Wongm's Rail Gallery, there is a photo of one, on a NQKY on a PN MA3/AM3 freight.
|MSC open top container. Could do with some flat varnish to take away the gloss look.|
I purchased mine off ebay, for the sum of EUR6.02, or at the time $8.62, plus postage. Go to http://stores.ebay.com.au/DS-AutoModelle?_trksid=p2047675.l2563 and search for containers.
I also purchased some nice European 45' reefer units in Ferroverde and Unit 45.com liveries. (These containers, for interest, transport fresh flowering plants from Holland to Italy by rail.
The above video is in Dutch, but one can get the sense of what it is about.
It is also interesting to note, that while Europe is generally electrified; cross border inter-modal services are hauled by diesel locomotives: though they use an electric in the video, and if you look closely, the loco changes between countires.
This is due to most European countries operating on different electric systems and voltages, so a Class 66/77 is able to travel non stop, while an electric hauled train has to stop at the border crossing to change locomotives. Strangely similar to Australia many years ago, before through running.)
