SECTION 7.0 Structure <strong>Gauge</strong> <strong>Envelopes</strong> for the PTV or Accredited Rail<br />
Operator – for new, or altered Infrastructure adjacent to, or in<br />
the Air Space over Track<br />
This section applies to any new, or alterations to existing Infrastructure constructed or installed by or<br />
on behalf of the PTV or accredited Infrastructure managers. These requirements are applicable only to<br />
tangent track. For curved track adjustments, refer to Section 4.2. Notes applicable to Figure 2:<br />
ENVELOPE F<br />
Envelope F applies to the placement of bridges, retaining walls (excluding platforms), bridge<br />
piers and structures adjacent to and/or in the airspace above the track.<br />

ENVELOPE G<br />
The minimum Vertical Clearance shall be 7.1m for new bridges and/or structures<br />
above track that has been identified to be used for interstate freight and/or for double<br />
stacked containers operations.<br />
Note for a grain gantry over a siding the Vertical Clearance can be reduced to 5.26m<br />
subject to approval of PTV.<br />
For track that is or is to be utilised for passenger and/or freight services and has no<br />
interstate freight or double stacked containers operation requirements, the Vertical<br />
Clearance may be reduced to a minimum of 5.75m subject to approval being<br />
granted to alter the height of existing overhead traction power wiring if required.<br />
The minimum Horizontal Clearance shall be 6.0m for bridge piers, bridge abutments<br />
and retaining walls (excluding platforms), where track access is required for road<br />
vehicles parallel to track.<br />
The minimum Horizontal Clearance shall be 4.0m for bridge piers, bridge abutments<br />
and retaining walls (excluding platforms), where track access is not required for road<br />
vehicles parallel to track, subject to the approval of PTV.<br />
The minimum Horizontal Clearance shall be 3.0m for bridge piers, bridge abutments<br />
and retaining walls (excluding platforms), where track access is not required for road<br />
vehicles parallel to track and where the track uses concrete sleepers or slab track,<br />
subject to the approval of PTV.<br />
Envelope G applies to the placement of verandah eaves adjacent to the track.<br />
V7<br />
V8<br />
H9<br />
H10<br />
There shall be a minimum Vertical Clearance of 7.1m for verandah eaves above<br />
track that has been identified to be used for interstate freight and/or for double<br />
stacked containers operations.<br />
For track that is utilised for passenger and/or freight services and has no future<br />
interstate freight and/or double stacked containers operation requirements, the<br />
Vertical Clearance may be reduced to a minimum of 5.26m for verandah eaves.<br />
There shall be a minimum Horizontal Clearance of 3m for verandah eaves where the<br />
track has been identified to be used for freight operations. Note in certain<br />
circumstances a reduced clearance of no less than 2.5m may be accepted subject<br />
to approval of PTV and the ARO.<br />
For track that is utilised for passenger services only and has no future freight<br />
requirements the minimum Horizontal Clearance may be reduced to 2.4m for<br />
verandah eaves.<br />
