Mr. craig tengström kuwait metro and rail

  1. 1. Kuwait Metro & Rail, 17-18 April 2012 Day 2 13h30-14h00 Presented by: Craig Tengström (Director)Copyright © 2010 Tubular Track. All rights reserved Confidential
  2. 2. • Began in the South African mining industry in 1989 to solve water drainage issues, reduce maintenance and increase track availability• With further development, was introduced into the surface environment with installations as far back as 1993• Full scale laboratory testing was done at the Transnet Freight Rail Testing Facility in 2000 to fully develop the system into pre-cast modular form• Has since evolved into a pre-cast track system with major capex and life cycle cost benefits• Installations in South Africa, Namibia, Botswana, Zambia, Canada, USA & Saudi Arabia• Representation in South Africa, Brazil, Australia, Namibia and Saudi Arabia
  3. 3. Low Cost, Modular, Pre-cast, Ballast-less, Desert ProvenMain Components of T-Track: 30MPa reinforced concrete beams Galvanized gauge bars Galvanized stirrups Rail fasteners Resilient pad Confidential 3
  4. 4. T-Track – a Cost Revolution in Major Track Systems BALLAST-LESS TRACK BALLASTED TRACK T-TRACK SLAB TRACKCAPEX 1 0.9 – 1.5 2–4OPEX 1 0.2 – 0.4 0.2 – 0.4 Confidential 4
  5. 5. T-Track – a Cost Revolution in Major Track Systems Confidential 5
  6. 6. T-Track – the Universal Rail Solution Ideal for Track applications: in all Environments: Main line  Desert Turnouts  Savanna Level crossings  Tropics Bridges  Tundra Viaducts  Underground Tunnels  Urban Sidings  Loading  HAZMAT as a result of: Incline shafts  Low initial cost  Low maintenance cost for Services such as:  Reduction in required rail sizes Mass transit  Improved drainage Light rail  Fixed geometry Theme parks  Guaranteed resilience Inter-city passenger  Continuous support of rails General freight  Integrated design Heavy haul freight  Strong partnerships Confidential 6
  7. 7. T-Track – the Universal Rail Solution Ideal for Track applications: in all Environments: as a result of: for Services such as: Confidential 7
  8. 8. Desert proven: No ballast – No Contamination. T-Track mitigates sand contamination Ballasted Track in KSA T-Track in KSADuring 2008 2009Construction 2011 2011In Operation Confidential 8
  9. 9. Additional benefits of T-Track: Reduction in Earthworks andFormation Volumes Confidential 9
  10. 10. Additional benefits of T-Track: Mitigation of Flooding Confidential 10
  11. 11. Additional benefits of T-Track: Trench-free Cabling Broadband fibre optic along the rail reserve Signalling communications Local power for points machines, interlockings, signals Reduces trenching costs Confidential 11
  12. 12. Additional benefits of T-Track: Simple third rail designs Confidential 12
  13. 13. Additional benefits of T-Track: Mitigation of DC stray currents Rebar in the T-Track module DC traction return current often strays "collects" the stray current from the return rail Properly interconnected rebar negatesExtensive research on how T-Track corrosion riskMitigates stray current Confidential 13
