Here in Antwerp (Belgium), with a large port nearby and associated rich history of people loading and unloading all kinds of transport, both "van de camion gevallen" ("fallen off the truck")) and "van de boot gevallen" ("fallen off the boat" (because we often say "boat" when we know very well that large thing we're talking about is actually a ship) have been very common expressions for a long time. I've never heard someone say "fallen of the train" though.
