• 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

Additional benefits of T-Track: Mitigation of DC stray currents

13

Rebar in the T-Track module "collects" the stray current

Extensive research on how T-Track Mitigates stray current

Properly interconnected rebar negates corrosion risk

DC traction return current often strays from the return rail
