They operate under the PBS (Performance Based Scheme).
That's the same configuration I was using on my last forays into Tram City.

I imagine there would be a bit of skidding on those quad bogie tyres.

You don't need quad bogies for that - a few years ago I was coming back from Perth through the wheatbelt in January. Following the harvest, the bitumen was very much the worse for wear at the turn-ins at the silos. I am pretty sure there were no quad bogies, mostly two or three double and triple dog trailers, the ones I saw, anyway - the harvest was pretty much finished but there was still a fair bit of grain coming in.

Mind you, the hot bitumen was pretty easy to damage by dragging tyres sideways.

Ian can correct me, but I'm pretty sure that come of the axles steer. At least that is what I have observed following some of the JR Stephens quad trailers around Ipswich.

Cheers,
Mick.

You're right Mick, some do but it's a balancing act minimising tyre wear.
The steerable axles need constant maintenance and alignment or they can wear tyres quicker than non-steerable. JRs do mostly, relatively short runs, so more turning.

Some are a damped castor, others linked to the turntable.

Are you suggesting that I would operate illegally? Perish the thought.

Anyone want to have a go at explaining the math for me?
