G'day Bob!

I don't know the legal definition of "road train", but it certainly
is the tractor pulling two or three trailers, & clearly marked as
Road Train. More common, and legal on designated routes in cities,
are "B Doubles", which are the tractor with two trailers, but with
the second trailer hitched above the wheels of the first, much as
with the first trailer to the prime mover. (if that makes sense)

Cheers, Steve..
