Drainage works

South Australia's public rail transport system is undergoing a major revitalisation, the largest and most complex since the 1920s.

The entire Noarlunga line and a large portion of the Gawler domestic rail line is being upgraded to prepare for electrification, planned to occur over the next 10 years.  The horizontal and vertical geometry is being improved, bridge clearances proofed, wooden sleepers replaced with concrete sleepers, and the track drainage system upgraded.

Tonkin Consulting designed the track drainage for approximately 60 km of rail line which involved collaborating with two interstate design teams, the client and contractor.  We were also engaged for the design and construction phase.

The design, prepared with 12d software, had to interface directly with rail formation design models to ensure adequate cover for the proposed pipes and adequate capacity within cess drains running parallel with the tracks.  At almost 60 kms of rail, the large scale of work called for most output being automated, including long sections and drainage schedules.
