Rio Tinto Track Maintenance

RTIO– Railways Division

2013 safety focus for railways division • Quality pre starts • Quality safety interactions • Quality pre-task hazard assessments • Leadership span of control Safety Leadership • SQRA & CCMP • HSEQ compliance • Align HSEQ and regulatory requirements • Fatigue Safety System Compliance • Hazard awareness • Focus on Line Of Fire • Mechanisation of repetitive tasks Hand Safety

Railways community safety campaign Rio Tinto’s focus of 2013 Rail Safety Week is ‘Safety at level crossings’. Rio Tinto supported this key safety message through an extensive Community Awareness Campaign titled Look, Listen, Live.

Integral part of the production network Rail is the key to the logistics chain • Ore is railed from 10 mine locations to 6 dumpers (3 at Dampier and 3 at Cape Lambert). • The current schedule (~249 Mtpa) is – Pooled fleet: 19 - 24 trains per day – RV J: 5 - 7 trains per day A 360 Mtpa system means; • 23% increase in tonnes, 20% increase in cars, 13% increase in loco’s, 7% increase in track • Railing from 12 mine locations to 7 dumpers (3 at Dampier and 4 at Cape Lambert) • 1 Mt per day, 40 loaded trains per day • Train movement every 20 minutes in dual track

Locomotives • A current total of 163 locomotives: - 72 x Dash 9 - 4 x Dash 8 - 87 x Evolution • Planned loco deliveries: - 10 x DC Evolution (mid 2013) - 6 x AC Evolution (early 2014) - 3 x DC Evolution (early 2014) 0 50 100 150 200 250 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 DC Traction - 72 GE Dash 9's - balance GE Evolution Series AC Traction ? Dash 9 replacements due to start ~2015

Train configuration • Very long, heavy trains. Operating at quartile 1 power to weight ratio of class 1 Heavy Haul rail operations • Pooled Fleet = 3 locomotives hauling 236 ore cars, Robe Valley = 3 locomotives hauling 166 ore cars • Banker locomotives (2 or 3) used for uphill gradients from mines • Average payload of 114 tonnes of ore per car = 33.9 tonnes average axle load. Upper control limit is 36 tonne axle load (governed by infrastructure) • Each train has a gross mass of approx. 32,300 tonnes and is 2.25 km long • A round trip to Yandicoogina is approx. 900km’s and uses 20,100L of fuel

Track equipment - Fixed Plant Flashbutt Welder and associated rail gantry system - 50 ballast hoppers including 7 side tippers with two plough cars - 2 Rail Train capable of carrying 48 by 400 m long rail strings - 1 x 64 stone & 1 x 56 stone Rail Mainline Grinding and 2 Switch Grinders (also 3 x 32 stone units on order) - 6 x Tamper machines for surfacing including turnouts - 3 x Ballast Regulators for shaping of the ballast section - 7 x Mobile Flashbutt Welders

Electronically Controlled Pneumatic (ECP)Brakes and Driver Assist ECP - Consistent and rapid braking to facilitate smoother train running - Retrofit of fleet commenced November 2011. Driver Assist – Advice to drivers on optimum throttle and brake setting to achieve the optimal run – Anticipated cycle time and fuel saving benefits

ECP – Verification of benefits

Summary •RTIO Railways is the largest privately owned heavy haul railway - “Traditional” heavy haul railway with large technology changes in progress - Rapid increases in rolling stock assets offset by minimal investment in track infrastructure - Complex logistics operation reliant on optimised planning, scheduling, execution and deviation management - Legacy infrastructure challenges managed through operational discipline - Efficiency opportunities with modernisation and mechanisation
