RMS con­sents to BAB-quads in na­tion’s north­west

Australian Transport News - - News -

The rst road man­ager con­sent to the Na­tional Heavy Ve­hi­cle Reg­u­la­tor (NHVR) has been granted for a pre­scrip­tive BAB- quad on the cur­rently ap­proved Type 2 road train route on the Mitchell High­way be­tween North Bourke and the Queens­land bor­der at Bar­ringun.

Roads and Mar­itime Ser­vices (RMS) says Trans­port for NSW has com­pleted a re­view of the NSW ac­cess pol­icy for Type 2 road train quad trailer com­bi­na­tions and has now opened ac­cess on this ap­proved route for pre­scrip­tive BAB and ABB- quad com­bi­na­tions un­der equiv­a­lent con­di­tions to those which ap­ply to cur­rent legacy A-triple Type 2 road trains.

Op­er­a­tion for these two quad trailer com­bi­na­tions is also avail­able up to 4.6m high on this route. Pre­vi­ous pol­icy re­quired such com­bi­na­tions to be rst ap­proved through the na­tional per­for­mance­based stan­dards scheme.

“Ac­cess for AAB- quad road trains will be con­sid­ered on a caseby- case ba­sis and sub­ject to demon­strated per­for­mance be­ing no worse than the cur­rent A-triple’s per­for­mance,” an RMS regulatory up­date states.

“Due to the ad­di­tional axles and thus in­creased to­tal mass of this com­bi­na­tion, ad­di­tional bridge as­sess­ments may be re­quired.”

Be­cause of the un­known com­par­a­tive per­for­mance of the BAA- quad road trains, this ac­cess de­ci­sion does not ap­ply to them.
