No feature type field exists for this annotation feature class. The feature type has only been included throughout the specification documentation for ease of reference.

Only Annotation associated with, or derived from, entities in feature classes grouped within the RailTransport feature dataset should exist within the RailTransportAnno feature class.

Wherever possible annotation should be stored using the subclasses indicated under AnnotationClassID. Annotation stored as inline text should be kept to a minimum.

Type for large polygons and long linear features may be held in an annotation feature for each word to allow for spacing and differences in orientation, see Section 2 chapter 4.

Annotation should not contain any HTML tags within the blob element, nor should it contain any special characters.

Editing and placement of Annotation should be conducted in the appropriate MGA 1994 zone to ensure the spatial position of type on the map face can be correctly represented.

Annotation should only occur where the associated feature either has a sufficient dimension size or Upperscale value to be shown at 1:100 000 scale or a smaller scale/larger extent (eg 1:250 000, 1:1 000 000)

General - All Scales

Size and any other selection criteria apply to all feature occurrences. All feature occurrences existing in the base material/digital data or NTDB meeting the minimum size for inclusion will be retained. Dismantled railways, including those on the latest previous edition map or base data/material will be retained/captured.

All railways and permanent sections of light railways will be shown.

Light railways are lightly constructed railways or tramways used for special purposes, for example scenic railways.

Where railways exist upon a jetty they must be coincident for the length of the railway.

All railways, including sidings and marshalling yards should be shown to scale if greater than the minimum size criteria.

The following railways will only be eligible for Upperscale Values for 1:250 000 and larger scales (smaller areas):

• short lengths of non-permanent light railways in position only for the purpose of seasonal harvesting of crops.
• railways privately run for tourism purposes.

Only railways with status of 'Operational', 'Abandoned' or 'Under Construction' will be eligible for Upperscale Values of 1:100 000 or smaller scales (larger areas). Only railways with status of 'Operational' (or 'Under Construction' which are of national significance) will be eligible for Upperscale Values of 1:2 500 000 or smaller scales (larger areas). The only exceptions will be Dismantled Railways identified by Geoscience Australia required for 1:1 000 000 Airservices products, these railways may be provided with an Upperscale of 1:1 000 000 but will not be utilised by any 1:100 000 or 1:250 000 database products.

In general when assigning Upperscale Values, if the depiction of all tracks in full map symbology for an applicable scale is ambiguous/cluttered, recalculate the Upperscale value for the applicable scale to only depict a general representative pattern.

General - All Scales

Nodes will appear at all Railway intersections.

Railway Crossing Lines (feature class) will be coincident with the equivalent section of the Railway. There must be a vertex in the Railway feature at the exact location of the start and end points of the Railway Crossing Line (feature class). The Railway must continue outwards from both endpoints of the Railway Crossing Lines (feature class).

Railway Crossing Points (feature class) must fall exactly over a vertex on the Railway feature.

Railway Stations will be coincident with a vertex on a Railway.

General - All Scales

Railways cannot overlap the following (except when associated with a Railway Bridge Line);
Canal areas, Perennial lakes, Perennial WatercourseAreas (feature class), Flood Irrigation Storage, Town Water Storage, Rural Water Storage.

Railways cannot overlap;
Sea except when coincident with a Jetty.

Railways cannot intersect;
Discontinuities (feature class).

General - All Scales

Railways will be labelled with their 'Route Name'.

All railways, including sidings and marshalling yards should be shown to scale if greater than the minimum size criteria.

Where scale limits the depiction of all tracks, show only those that depict a general representative pattern.

Abandoned railways will be labelled 'abandoned'.

Railway lines will not be labelled with their gauge width.

Railways which are dismantled will not be shown on the map face.

Railways will be masked where black type unavoidably overprints the feature. The break measurement will be 0.2 mm on either side of the type where it crosses the feature. (Note: the feature will be masked only on the map and will be complete in the data.)

For all products other than WAC Dismantled Railways will not be included on the map face.

General - All Scales

Size and any other selection criteria apply to all feature occurrences.

All new railway bridges should be captured as Railway Crossing Lines (Railway Bridge Line or Railway Overpass), where the structure has been constructed only to prevent an intersection with other road or rail traffic the Railway Overpass feature type should be utilised instead of the Railway Bridge Line feature type.

Existing Railway Bridge Points on the base material/digital data or the latest previous edition map should be recaptured as Railway Crossing Lines (Railway Bridge Line or Railway Overpass) during maintenance/revision processes unless there is evidence that they no longer exist. When applicable the associated Railway Bridge Point in the base material/digital data should be deleted. When the extent on a bridge is unclear, an Action Request should be sent to Geoscience Australia seeking locational information (eg imagery, plans, etc).

Existing crossing lines (e.g. bridges, causeway) on the base material/digital data or the latest previous edition map should be retained/captured unless there is evidence that they no longer exist

The railway line for which the bridge was made need no longer exist, however, to be shown the bridge must still exist.

Bridges of distinctive construction may be textnoted (e.g 'drawbridge', 'swing bridge').

For all of the following statements, feature width values assigned in the Railway Bridge Line symbol representations should reflect the associated railway gauges see Feature Width Meaning for more details.

For SYMBOL 100K, only Railway Bridge Lines equal to, or greater than, 40m and associated with a railway classified as equal to, or greater than, UPPERSCALE 100000 should be shown with a symbol other than 1 - line no draw. The only exception would be a bridge of historical significance or a bridge no longer associated with a defined railway which still meets the minimum size for map representation. For Railway Bridge Lines equal to or greater than 40m and less than 50m these should be represented as point bridges (eg 4028 - Bridge Line to Point FeatWid 025). For Railway Bridge Lines equal to or greater than 50m these should be represented as linear bridges (eg 4020 - Bridge Line FeatWid 025).

For SYMBOL 250K, only Railway Bridge Lines equal to, or greater than, 40m and associated with a railway classified as equal to, or greater than, UPPERSCALE 250000 should be shown with a symbol other than 1 - line no draw. The only exception would be a bridge of historical significance or a bridge no longer associated with a defined railway which still meets the minimum size for map representation. For Railway Bridge Lines equal to or greater than 40m and less than 100m these should be represented as point bridges (eg 4028 - Bridge Line to Point FeatWid 025). For Railway Bridge Lines equal to or greater than 100m these should be represented as linear bridges (eg 4020 - Bridge Line FeatWid 025).

For SYMBOL WAC1Mil, only Railway Bridge Lines equal to, or greater than, 500m and associated with a railway classified as equal to, or greater than, UPPERSCALE 1000000 should be shown with a symbol other than 1 - line no draw. The only exception would be a bridge of historical significance, a bridge identified by Airservices Australia for inclusion on WACs or a bridge no longer associated with a defined railway which still meets the minimum size for map representation. For Railway Bridge Lines equal to or greater than 500m and less than 1000m these should be represented as point bridges (eg 4025 - Bridge Line to Point FeatWid 08). For Railway Bridge Lines equal to or greater than 1000m these should be represented as linear bridges (eg 4020 - Bridge Line FeatWid 025).

For all of the 3 above paragraphs the following applies:

• All bridges with a status of dismantled will be given a symbol value of 1 - line no draw.
• Where cartographic clutter occurs, only significant bridges will be shown. The significance of the bridge depends on the number of bridges in the vicinity, the importance of the railway etc. As guidance, the selection from the latest previous edition map will be taken and a similar approach applied to any new bridges. In this case, bridges not considered significant will be given a symbol value of 1 - line no draw.

General - All Scales

Railway Bridge Lines will be coincident with the equivalent section of the Railway. There must be a vertex in the Railway feature at the exact location of the start and end points of the Railway Bridge Line. The Railway must continue outwards from both endpoints of the Railway Bridge Line.

Railway Bridge Lines may be shown off the rail network if they are on a dismantled railway not represented in the Railway Feature Class.

General - All Scales

Bridges which carry both road and rail traffic will be held as coincident road bridge and railway bridge features in their respective layers.

General - All Scales

Bridges of distinctive construction may be labelled (e.g 'drawbridge', 'swing bridge').

Railway bridges will be named, where name is known.

Only Railway bridges that are not 'dismantled' will be shown on the map.

Railway bridges 'under construction' will be labelled 'under construction'

A bridge representation (cartographic representation) may be required to be extended to ensure that the map symbol endpoints (wings) effectively fall outside the width of its associated waterbody.

Existing Railway Bridge Points on the base material/digital data or the latest previous edition map should be recaptured as RailwayCrossingLines (Railway Bridge Line or Railway Overpass) during maintenance/revision processes unless there is evidence that they no longer exist. When applicable the associated Railway Bridge Point in the base material/digital data should be deleted. When the extent on a bridge is unclear, an Action Request should be sent to Geoscience Australia seeking locational information (eg imagery, plans, etc).

All new railway bridges should be captured as RailwayCrossingLines (Railway Bridge Line or Railway Overpass).

The railway line for which the bridge was made need no longer exist, however, to be shown the bridge must still exist.

Bridges of distinctive construction may be textnoted (e.g 'drawbridge', 'swing bridge').

When assigning Upperscale for Railway Bridge Points, for Upperscale of 250000 and smaller scales (larger areas), only significant bridges will be shown. The significance of the bridge depends on the number of bridges in the vicinity, the importance of the road etc. As guidance, the selection from the latest previous edition map will be taken and a similar approach applied to any new bridges

For feature width values assigned in the Railway Bridge Point symbol representations should reflect the associated railway gauges see Feature Width Meaning for more details.

For all of the following statements, feature width values assigned in the Railway Causeway symbol representations should reflect the associated railway gauges see Feature Width Meaning for more details.

For SYMBOL 100K, only Railway Causeways equal to, or greater than, 200m and associated with a railway classified as equal to, or greater than, UPPERSCALE 100000 should be shown with a symbol other than 1 - line no draw. The only exception would be a causeway of historical significance or a causeway no longer associated with a defined railway which still meets the minimum size for map representation. For Railway Causeways equal to or greater than 200m these should be represented as linear causeways (eg 4008 - Railway Causeway FeatWid 025).

For SYMBOL 250K, only Railway Causeways equal to, or greater than, 500m and associated with a railway classified as equal to, or greater, than UPPERSCALE 250000 should be shown with a symbol other than 1 - line no draw. The only exception would be a causeway of historical significance or a causeway no longer associated with a defined railway which still meets the minimum size for map representation. For Railway Causeways equal to or greater than 500m these should be represented as linear causeways (eg 4008 - Railway Causeway FeatWid 025).

For the 2 above paragraphs the following applies:

• All causeways with a status of dismantled will be given a symbol value of 1 - line no draw.
• Where cartographic clutter occurs, only significant causeways will be shown. The significance of the causeways depends on the number of causeways in the vicinity, the importance of the railway etc. As guidance, the selection from the latest previous edition map will be taken and a similar approach applied to any new causeways. In this case, causeways not considered significant will be given a symbol value of 1 - line no draw.

General - All Scales

Railway Stations on Dismantled lines will be given an Upperscale value of 25 000.

All railway stations on operational and abandoned lines (including disused/abandoned railway stations) will be assigned a minimum Upperscale value of 250 000. The only exception will be non-operational railway stations where there is clear evidence that the buildings and associated structures no longer exist (i.e. have been dismantled) which will be given an Upperscale value of 25 000.

All operational or under construction Railway Stations, situated upon railway lines assigned with an Upperscale values of 1 000 000 or smaller scale (greater area), will be given the equivalent Upperscale value of its associated railway. Abandoned and Dismantled Railway stations will not be eligible for Upperscales values of 1 000 000 or smaller scales (greater area).

The following applies to symbol assignments for all scales eg SYMBOL100K, SYMBOL250K:

• Railway stations must be assigned the equivalent Upperscale value or smaller scale (greater area) to have a symbol value other than NULL.
• Railway stations with the equivalent Upperscale value or smaller scale (greater area) must have one of the legitimate symbol values as per the applicable symbol number listing.
• Railway stations on underground lines will not be symbolised (e.g symbol = 2 - point no draw).

For SYMBOL100K and SYMBOL250K, all Railway Stations with the equivalent Upperscale value or smaller scale (greater area) will have a symbol of 222 unless denoted to be given a symbol 2 - point no draw from either the paragraphs above or when the resultant symbolisation causes clutter with surrounding detail of higher significance to the user .

For SYMBOLWAC1MIL, all Railway Stations with the equivalent Upperscale value or smaller scale (greater area) will have a symbol of 222 unless

• denoted to be given a symbol 2 - point no draw from either the paragraphs above, or
• when the resultant symbolisation causes clutter with surrounding detail of higher significance to the user, or
• where the location of the railway station is already represented by either a Built Up Area or Populated Place of the same name, or
• where the railway station is fully contained within a Built Up Area polygon

For SYMBOL2_5MIL and SYMBOL5MIL, all Railway Stations with the equivalent Upperscale value or smaller scale (greater area) will have a symbol of 2 - point no draw.

General - All Scales

Railway Stations will be coincident with a vertex on a Railway.

General - All Scales

The names of dismantled Railway Stations and Railway stations on dismantled railway lines will be depicted as feature type 'Place Name' if the same name is not in use for another 'Place Name', 'Populated Place' or 'Built Up Area' feature. Unless there is clear evidence they no longer exist (i.e. have been dismantled), the buildings will be retained shown as BuildingPoint or BuildingArea feature class entities as appropriate.

A Railway Station situated on a Jetty must be coincident with a vertex on both the Jetty and its associated Railway Line.

Railway stations will be cloned as a Place Name if the same name is not in use for another Place name or Populated Place.

1:25 000

All railway stations will be named unless station is not symbolised.

1:100 000

All railway stations will be named unless station is not symbolised.

1:250 000

Railway stations within Built Up Areas will only be named where space permits, all other railway stations will be named unless station is not symbolised.

General - All Scales

Type for Railway stations which are cloned as Place Names will be as specified for Railway stations and not Place Names.

Abandoned railway stations on operational lines will be labelled 'abandoned' outside Builtup Areas. Abandoned Railway stations on abandoned lines will not be so labelled.

Size and any other selection criteria apply to all feature occurrences. All feature occurrences existing in the base material/digital data or NTDB meeting the minimum size for inclusion will be retained unless there is clear evidence they no longer exist.

All new railway tunnels should be captured as Railway Tunnel Lines.

Existing Railway Tunnel Points on the base material/digital data or the latest previous edition map should be recaptured as Railway Tunnel Lines during maintenance/revision processes unless there is evidence that they no longer exist. When applicable the associated Railway Tunnel Point in the base material/digital data should be deleted. When the extent on a tunnel is unclear, an Action Request should be sent to Geoscience Australia seeking locational information (eg imagery, plans, etc).

Tunnels which carry both road and railway traffic will be held as a coincident road tunnel and railway tunnel feature in their respective layers.

Railway tunnels will be named where name is known.

Dismantled Railway Tunnels will not be eligible for a symbol other than 1 - line no draw for all scales.

For SYMBOL 100K, only Railway Tunnel Lines above 100m and associated with a railway classified as UPPERSCALE 100000 should be shown with a symbol other than 1 - line no draw. The only exception would be a tunnel of historical significance or a tunnel no longer associated with a defined railway which still meets the minimum size for map representation. For Railway Tunnel Lines greater than 100m these can be represented as linear Tunnels (205 - Tunnel Line).

For SYMBOL 250K, only Railway Tunnel Lines above 250m and associated with a railway classified as UPPERSCALE 250000 should be shown with a symbol other than line 1 - line no draw. The only exception would be a tunnel of historical significance or a tunnel no longer associated with a defined railway which still meets the minimum size for map representation. For Railway Tunnel Lines greater than 250m these can be represented as linear Tunnels (205 - Tunnel Line).

For SYMBOL WAC1Mil, only Railway Tunnel Lines above 1000m and associated with a railway classified as UPPERSCALE 1000000 should be represented as linear Tunnels (205 - Tunnel Line), all other tunnels will be shown with a symbol 1 - line no draw.

For all of the 3 above paragraphs the following applies: Where clutter occurs only significant tunnels will be shown. The significance of the tunnel depends on the number of tunnels in the vicinity, the importance of the railway etc.

For SYMBOL2_5MIL, SYMBOL5MIL and SYMBOL10MIL all Railway Tunnel Lines will be given 1 - line no draw.

General - All Scales

Railway Tunnel Line will be coincident with the equivalent section of the Railway. There must be a vertex in the Railway feature at the exact location of the start and end points of the Railway Tunnel Line. The Railway must continue outwards from both endpoints of the Railway Tunnel Line.
