I should have known, but it didn’t occur to me that they would use road trains to transport cars in Australia. And here’s one to prove it, a 1973 White 4000 powered by a Cummins 335, shot in Adelaide River, NT in 1974. And the driver is dressed for the period (and the heat) in his short shorts.
Here’s a few more from down under:
This Mack hauling Fords is a bit shorter, with only two trailers.
Not exactly road trains, but some vintage Australian cars and trucks to savor.
