Yanco to Griffith Railway

The Challenge:

Over 50 km of this railway line needed to be re-sleeped and re-railed. This required a rail alignment in order to maximise the life of the build. The curves needed to be designed to achieve 80 km/h train speeds with the final alignment not to have major track pulls from the existing alignment. 

The Solution:

Survey work commenced in October 2014 with final project delivery in December 2014.

The work to complete the project comprised of :

• installation of permanent survey control marks along the length of the section.
• the undertaking of surveys to establish Map Grid of Australia coordinates on the control marks.
• the survey of the existing track running face on the curves and parts of the straights.
• the track re-design to enable the track class specification whilst minimising the amount of lateral track "pulls".
• the placement of sufficient track construction marks (TCMs) at each curve to allow the tamping crews to "pull" the track to the design geometry.
