The document summarizes T-Track, a pre-cast modular ballast-less track system developed in South Africa. It has been installed in several countries for various rail applications. Key points include: - T-Track was originally developed to address drainage issues in mines and has evolved into a pre-cast system with capital and life cycle cost benefits over ballasted track. - Installations have occurred in several African and Middle Eastern countries, as well as North America and Australia. - The system provides benefits such as reduced earthworks, mitigation of flooding, simple cabling and third rail designs, and reduction of stray currents. - T-Track has been proven in desert environments in Saudi Arabia since 2008

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

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 negates
Extensive research on how T-Track corrosion risk
Mitigates stray current
