A B-Triple is similar to a B-Double: an articulated vehicle with the second
and third semi-trailers attached to the trailer in front by means of a
turntable.
A Road Train is a vehicle combination with more than two points of
articulation and coupled together using dollies. A double roadtrain has
two trailers... triple roadtrain has three trailers...
A 'plain' semi-trailer is a prime mover coupled to a semi-trailer using a
turntable.
Only Victoria and Queensland are trialing B-Triples at the moment, very
well by the sounds of it too.
