All comes down to what is allowed were it works. Different size trains allowed in different parts. Rough guild is steer axel allowed 6t, a bogie group 16t and tri group 20.5t, this is all gross and lots of other rules and permits come into it. A basic two trailer with a steer, 2 bogie groups and two tri groups would be 6t+16+16+20.5+20.5=79t gross. Take off say 10 for primover, 14 for two trailers and 2 for dolly so tare of 26t gives a mass of 53t. Than there permits and mass, lighter tare weights and more axle groupings and bigger axle groupings come into play.

the blokes we use to cart our grain can take 75t out the gate

In the drought of 2007 I went off farm and drove road trains from an iron ore mine to a rail head, this truck was legal for a 96t payload and grossed at 140

theres a difference? thats what we call a road train on this side I never actually thought about it like that, most doubles on this side fall into the "long Vehicle" category and unless you're towing a couple of 40 footers, 2 trailers wont get you into "Road Train" territory here

Okay funny how it changes most blokes over here that cart grain seem to get going to AB triples now but most of the areas we work can't have triple road trains they are to long.

But with a AB Triple I think your pay load is near 80t.

My theory stevo doesn't matter what configuration you have all the grain is going out over the same road.

A two trailer road train with out mass is not much batter off than a bdouble on mass. 6+16.5+23+23=68.5t on mass for a bdouble, a set up on the light side tares at 23t to give 45.5t mass. Mass management is worth 2.5t on tri group and 0.5t on bogie group.

Still amaze me the amount of full time truckies that run newer gear that tares off heavy as. Down here most would run as a bdouble for 90% of the time but run a road train ratted primover and set of trailers rated for road train. That extra bit of tare weight must near cost them more than the bit the make running as a train.
