Rail Revitalisation Project
This Rail Revitalisation project in South Australia was part of the state’s
$2.6 Billion upgrade to public transport services. The survey aspect of that
involved over 110 kilometres of Adelaide’s metropolitan rail network.
Annotation with lengthy descriptions was used in survey models which combined
services, signals, numerous pieces of track equipment, and stations. Attaching
photography to the survey data was required to better display the features. Due
to the number of photographs taken (in the order of 1,000), an automated
methodology was required to achieve the results.
In addition, the rail corridor contained a mass of assets unique to railways - a
challenge for a department largely focused on road projects prior to this
Using a GPS camera, the team added images and site photos into 12d Model in an
automated process to supplement a standard survey model with information that
would not be practical to key in as text.
Using the CAD Insert Image command to insert a JPEG into a 12d Model project
allowed them to set a precedent for other images to follow - the first image was
inserted as a sample only, with the manual process needing only to be done once.
Adding attributes to the point/inserted image allowed for attributed information
either pertaining to or extracted from the image to be associated with the
Exporting the model with the sample
image provided a base for the mail merge to be set up.
GPS-Photo Link camera software facilitated a CSV Export of the images with their
associated coordinates and attributes.
attribute columns that needed to be populated manually were added, and needed to
correspond with the field names in the 12d ASCII file, as created previously.
The mail merge document was created, merging the repetition of the single point,
with a JPEG appended for each field photograph and creating a model of points
Initially, photographs were used
to remove large quantities of text from the survey model, avoiding lengthy
descriptions of assets cluttering the view. The uses for this quickly grew to
• Identifying signal numbers and
• Determining track circuit
• General Site and track
• Geotechnical bore
The finished product allowed
for a virtual site visit capturing far more than just engineering survey
breaklines. 12d Model managed datasets across multiple disciplines including
Design, Signalling, Geotech, Contamination, and asset management.
