Gear Rail Systems in South Africa: Innovations and Applications

Across South Africa and the broader African continent, there's a growing emphasis on enhancing railway infrastructure to support various transportation needs. This includes everything from high-speed mainlines and urban traffic networks to heavy-haul long-distance iron ore and coal haulage, as well as underground mining tracks.

The Role of Grindrod in Rail Infrastructure

Grindrod plays a significant role in the development and maintenance of rail systems in South Africa and beyond. The group believes Grindrod Locomotives’ strategy of offering holistic services is hugely beneficial to its customers.

Grindrod Locomotives

From its workshops in Pretoria, Gauteng, Grindrod Locomotives provides locomotive design, engineering and manufacturing solutions. The company assembles new diesel electric locomotives and also refurbishes and upgrades old locomotives.

During the development phase of new locomotives, it has become clear to Grindrod that Africa has unique needs, such as the narrow Cape gauge predominantly used and the need for tractive effort over speed. Grindrod Locomotives’ manufacturing chain is simple and spares are common, which makes aftermarket support cost-effective.

In support of the Department of Trade and Industry’s initiative to localise the production of parts and components, which seeks to add to local job creation and contribute to economic development, Grindrod has tripled the manufacturing capacity of its Pretoria plant.

As the business expands, the company is enlarging its maintenance footprint by providing regional hubs in several African countries to ensure that operators achieve acceptable locomotive availability rates.

Grindrod Rail Construction (GRC)

Grindrod’s subsidiary, Grindrod Rail Construction (GRC) - formerly RACEC - is an industry leader in rail track construction, rehabilitation, electrification and maintenance. The private sector companies that GRC works with are primarily mining and commodity companies.

The State-owned companies that GRC engages with are primarily rail and port authorities, and local and international entities responsible for building and maintaining rail transport infrastructure.

Grindrod Pembani Remgro Leasing Africa (GPR Leasing)

GPR Leasing provides access to innovative and highly competitive debt funding that enables the company to offer the lowest locomotive rates in the market and provides Africa’s rail operators the leasing solutions they need to unlock the huge potential for growth in the freight rail sector.

Partnership with GEAR Rail Technologies

Grindrod has partnered with GEAR Rail technologies - a rail technology solutions business with strategic contracts in Kenya, Mozambique, Nigeria and South Africa. The business specialises in providing track warrant systems, automated signalling systems and communication systems under various agency and joint venture arrangements with major international rail technology companies seeking to pursue rail infrastructure projects in Africa.

Modernization and Technology in Rail Systems

Across the global rail industry, Internet of Things (IoT) technologies are reshaping how networks are inspected and maintained. Onboard sensors, scanning systems, and advanced analytics now work together to generate a virtual, geo-referenced model of the railway asset.

For the RASC® (Railway Asset SCanning) solution, this means delivering a precise, spatially accurate record of asset condition above and below ground. Together, they have introduced next-generation asset condition monitoring to support the continent’s evolving transport infrastructure.

ABB's Contribution to the Rail Sector

Rudolf explains how ABB supports the rail sector with low- and medium-voltage components that are critical for both passenger and freight rolling stock. He highlights the importance of supplying safe, lightweight and reliable equipment that complies with international fire and smoke safety standards, widely applied across Africa.

The conversation reflects ABB’s strong customer base in South Africa, including PRASA, Gautrain and Transnet, alongside major international operators such as Deutsche Bahn and Amtrak.

Historical Significance

Built by Dübs Locomotive Works in Glasgow, Scotland, in 1897, this Class 6A is among the oldest operational steam locomotives on the African continent. The unveiling event will recognise the craftsmanship involved in returning this significant locomotive to working order and the broader heritage value of South Africa’s steam era.

The Class 6 series, first introduced in 1893, earned a reputation as one of the most versatile and economical locomotive classes to operate in South Africa. Originally deployed for fast passenger services, the type later became the reliable workhorse of suburban, branch line and shunting duties countrywide, excluding Natal.

Historical records note their speed, ease of handling, strong steaming qualities and low maintenance costs, with lengthy intervals between overhauls. They dominated Cape suburban services until electrification in 1928 and worked key Witwatersrand routes until traffic demands outgrew their capacity.

Expansion and Projects Across Africa

Turning to the continental picture, Holley highlights Traxtion’s growing footprint, with operations already established in nine countries and a tenth, Guinea, coming online soon. He points to the company’s contracts in Angola, supporting Lobito Atlantic Railway and the DRC, as well as a new third-party maintenance and training support project in Guinea.

Currently, Grindrod Rail’s main focus is on the development of the North West Rail project, in Zambia, where the lack of an efficient rail system is negatively impacting on growth prospects for the region. The route of the line will run westwards from Chingola, in northern Zambia, to Jimbe, on the Angolan border, and connect with a new branch line into the Benguela Railway at Luacano, in Angola.

The new 590 km railway in Zambia will reopen the Western Corridor to the Angolan port of Lobito, which has been closed for the past 30 years. The railway will service domestic and international traffic for the copper mining industry in northern Zambia and the southern Democratic Republic of Congo (DRC), and allow landlocked Zambia to import oil directly from Angola in the future.

Beitbridge Bulawayo Railway (BBR)

Grindrod has a joint controlling interest in Beitbridge Bulawayo Railway (BBR), which is a rail concessionaire operating in Zimbabwe. The concession provides a key link in the North-South corridor linking the South African ports of Durban and Richards Bay and the copperbelt in Zambia and the DRC.

The concession included a BOT arrangement to construct 150 km of new track and upgrade 172 km of existing track. Through Grindrod’s involvement in the concession over the last two years, BBR has invested in new mainline freight locomotives for the corridor, the first such initiative in over a decade.

Through the investment in more reliable rolling stock and the injection of additional rail expertise, BBR has also now seen significantly reduced train transit times on the Zimbabwe link of the North-South corridor.
