“Revitalising South Africa's rail sector demands a concerted effort in research and innovation. By embracing sustainable and adaptive strategies, leveraging advanced technologies like the Logistics Observatory and fourth industrial revolution tools, and aligning with global climate goals such as COP 28, we can ensure a safe, efficient and resilient rail network that supports our economy and society.” — Dr Sandile Malinga

The South African Heavy Haul Association (SAHHA) 2024 conference recently convened at the Emperors Convention Centre in Johannesburg, drawing industry luminaries to explore the theme, “Positioning Heavy Haul for Success.” The event highlighted great strides in rail technology that are set to reshape the landscape of heavy-haul transportation. The CSIR showcased its innovative technologies, presented its current research, development and innovation in the rail space and participated in a robust panel discussion.

Gculisile Mvelase, the senior researcher for CSIR Smart Mobility, presented her award-winning paper on "Assessing Track Ballast Durability." The study introduced revolutionary techniques for analysing the track ballast’s durability using enhanced aggregate imaging technology. Mvelase stressed that traditional methods have fallen short in diagnosing and resolving issues in rail track design and maintenance, and this new technology promises greater accuracy in predicting the lifespan and performance of critical rail components. Leveraging data with such accuracy could see a significant divide between enduring infrastructure and frequent, costly repairs, marking a pivotal turn in how we build and maintain rail systems.

CSIR Group Executive for Smart Society, Dr Sandile Malinga, participated as a panellist in a discussion on promoting rail industry research in South Africa. Dr Malinga commended the collaboration between CSIR and the SAHHA, emphasising that this partnership signifies a strategic move towards making rail transport more efficient, sustainable, and resilient. He highlighted that focused research and innovative applications, fostered by events like SAHHA, have the potential to enhance South Africa's heavy-haul rail infrastructure, positioning the country as a global leader in rail technology.

The CSIR exhibition stand at SAHHA also drew attention to the Ultrasonic Broken Rail Detection (UBRD) system, a collaborative development between the CSIR and Armscor's Institute for Maritime Technology. This innovation has been instrumental in preventing train derailments by detecting rail fractures early, thereby saving millions and ensuring uninterrupted rail service. With the successful implementation of the Sishen-Saldanha heavy freight line and ongoing trials with Indian Railways, UBRD has established itself as a cornerstone technology in enhancing rail safety globally.

Beyond rail tracks, the CSIR showcased its innovation in overhead power lines/ catenary distribution systems with fault-detection cameras, which were commercialised through Uvirco. Adding further value to the conference, the Survey and Inspection Device (SID) proved its capability as an autonomous rail vehicle designed to conduct inspections of various track parameters including trackside and wayside equipment.

The CSIR’s contribution at SAHHA 2024 positioned its commitment to a broad vision for a whole lifecycle approach encompassing manufacturing, safety and the digitisation of rail systems. Heavy-haul rail operations are indispensable for transporting South Africa’s vast mineral and agricultural wealth. “However, the alarming shift from rail to road, driven by rampant infrastructure theft and vandalism, amongst other factors, has not only strained the country's road networks and inflated transportation costs, but has significantly weakened logistics value chains. The rechannelling of heavy-haul logistics back to rail is essential for economic stability and growth,” said Nomsa Dlamini, Executive Cluster Manager for CSIR Smart Mobility.

Aligning these efforts with sustainability takes on greater significance in light of global climate imperatives, such as those underscored at COP 28. The CSIR's sustainable research strategies not merely address national challenges but also contribute to the global agenda for climate resilience and lower carbon footprints. By leveraging fourth industrial revolution technologies, the CSIR enhances asset management, operational efficiency and the overall sustainability of rail systems.

For investors, this confluence of advanced technology, sustainability and economic necessity presents a compelling case for financial support. The CSIR's ongoing research projects are not mere experiments but viable solutions that promise substantial returns through improved efficiency, lower operational costs and enhanced safety. By investing in these technologies, stakeholders are not only contributing to a robust rail future but also to a sustainable and climate-resilient world.

The narrative that unfolded at the SAHHA 2024 conference is a persuasive call for investment and innovation in the rail industry. With the CSIR at the helm, the journey towards an enhanced, sustainable, heavy-haul rail system is not just a possibility but an impending reality.
