Technical-Networking Meetings

PWI NSW holds five Technical-Networking Meetings per year to provide members with a technical focus, enhance knowledge sharing and encourage regular networking amongst members.

Meetings are held at the Sydney Masonic Centre, 66 Goulburn St, Sydney.

Technical Meeting Sponsors for 2018 are:

Next Technical-Networking Meeting
Joint meeting with IRSE
Thursday 21st June 2018 @ 5pm

Proudly sponsored by WSP



WSP, in conjunction with ARTC, will present the lessons learnt from the detailed design work on the Parkes to Narromine section of Inland Rail, including the technical aspects of the perway design as well as the signalling design and level crossing requirements for the 1700 km project.

Designing Inland Rail

IAustralian Rail Track Corporation (ARTC) is delivering the Inland Rail project to establish an efficient standard gauge freight linkbetween Melbourne and Brisbane which will support travel times of less than 24 hours between Melbourne and Brisbane. The1700 km line is Australia’s largest freight rail infrastructure project and is the key to unlocking regional Australia’s economicpotential.
In 2017 WSP (in Joint Venture with Mott MacDonald) was engaged by ARTC to provide the detailed design work for theupgrade of 107 km of the existing rail corridor between Parkes and Narromine and, in a separate engagement, 186 km fromNarrabri to North Star. The scope of work includes survey, geotechnical, hydrology/hydraulics, formation, track design, over400 culverts and 20 underbridges, over 150 level crossings, signalling and almost 800 utility crossings. In 2018 the WSP/MottMacDonald team was also awarded the Feasibility Phase design for the Illabo to Stockinbingal section of the Inland Rail project, a 37 km long greenfield alignment.
The presentation for both the PWI and IRSE will be jointlydelivered by WSP and ARTC and will cover the lessons learntfrom the detailed design work on Parkes to Narromine. ARTCwill provide an overview of the project, with WSP coveringtechnical aspects of the Perway design, including how factorssuch as hydrology, geotechnical conditions, existing sidings,and level crossings have influenced the design.The IRSE presentation will be delivered by Brett Hillcoat, WSP’sProject Manager for the Illabo to Stockinbingal project andmanager for site investigations on Parkes to Narromine. Brettwill cover signalling design and level crossing requirements forInland Rail. Brett leads WSP’s Newcastle Rail team and is oneof WSP’s Senior Project Managers, with more than 30 years’ experience delivering major works, including Phase 1 Inland Rail work in Victoria and NSW.




Previous Technical-Networking Meeting
was on WEDNESDAY 18th April 2018 @ 5pm

Proudly sponsored by Sydney Trains


John McLeod, Professional Head of Track Engineering at Sydney Trains and Prof. Huijun Li from the University of Wollongong will present their research into crack propagation and squat growth in rails and discuss the impacts for the rail industry in the treatment and prevention of squat defects.

Evolution of rail surface degradation in the tunnel

Evolution of rail surface degradation in the tunnel The role of water on squat growth under service conditions Theoretical research hypothesises that the hydraulic entrapment of water is critical to crack propagation associated with squat growth. This explains why squats do not occur in track inside tunnels. However, metallurgical evidence from ex-service rails damaged by the presence of water at the wheel and rail interface is lacking. A localised section of rail was discovered to have suffered severe surface damage as a result of water dripping from an air-conditioning system located in the tunnel roof. This section of rail offered an ideal controlled location for a detailed metallurgical investigation of the formation of white etching layers (WELs) under both dry and wet conditions. The study would also examine the relationship between WELs and squat initiation and the mechanics of water on crack propagation and squat growth of ex-service rail. This presentation will reveal some of the surprising evidence gathered during this study and discuss the potential impacts for the rail industry in the treatment and prevention of squat defects.



Technical-Networking Meeting Sponsorship

Sponsorship opportunities for the Technical Meetings are opened and sought from the AGM in August each year. Alternatively companies can make a nomination to sponsor a meeting by emailing the PWI meetings sub-committee on meetings@pwinsw.org.au

Sponsorship of 2019 Technical Meetings will be opened at the 2018 AGM (16th August).
