Quad road train access improves in NSW

  • Posted on Tuesday 11th, July 2017.

High productivity vehicle road access has improved in New South Wales, with consent granted for prescriptive BAB and ABB quad combinations to use the currently approved Type 2 Road Train route on the Mitchell Highway between North Bourke and the QLD border at Barringun.

In a regulatory update, Roads and Maritime (RMS) advised that access has been granted on the back of a review of the NSW access policy for Type 2 road train quad trailer combinations.

While BAB and ABB quad combinations up to 4.6m high and 53.5m long can now operate under equivalent conditions to current legacy A-triple Type 2 road trains, AAB quad road trains will only be considered on a case by case basis, and BAA quad road trains are not included in the new access agreement.

The RMS consent means that BAB and ABB quad combinations no longer need to be approved under the Performance-Based Standards (PBS) scheme to run on the route.

Conditions do apply for the quad combinations to gain access. For example, no mixed loads are permitted and combinations are restricted to a maximum speed of 90km/h.

Axle limits are outlined in tables 1 and 2 below. To operate at axle or total combination masses above Concessional Mass Limits (CML) up to Higher Mass Limits (HML), operators must be enrolled in the Intelligent Access Program (IAP).
