The Sishen Line: A Testament to Engineering Excellence

The Sishen line, a vital railway artery in South Africa, has been a cornerstone of the country's iron ore mining industry for decades. The 264-kilometer line connects the Sishen iron ore mine in the Northern Cape to the Port of Saldanha Bay, where the ore is shipped to global markets. But what makes this line truly remarkable is the sheer scale of the trains that haul the precious cargo.

The 17E Locomotives: A Marvel of Engineering

At the heart of these behemoth trains are the 17E locomotives, built by Union Carriage and Wagon in South Africa. These iconic machines are designed to haul massive trains of up to 4,500 tons of iron ore, making them some of the most powerful and impressive locomotives in the world. But what sets them apart is their unique design and construction.

The 30mm Steel Plating: A Necessity for Stability

The 17E locomotives feature a unique 30mm steel plating on their sides, which may seem excessive at first glance. However, this added reinforcement is crucial for preventing twisting and maintaining stability during the long hauls across the Sishen line. The sheer weight and momentum of these massive trains would cause even a sturdy locomotive to twist and wobble, putting the entire train at risk.

The 30mm steel plating provides a sturdy foundation for the locomotive, ensuring that it remains straight and true as it hauls its heavy load. This innovative design has allowed the 17E locomotives to become an integral part of the Sishen line's operations, hauling millions of tons of iron ore every year.

Union Carriage and Wagon: A Legacy of Excellence

Union Carriage and Wagon, the company that built the 17E locomotives, has a rich history of innovation and excellence. Founded in 1923, the company has been at the forefront of railway manufacturing in South Africa for nearly a century. Although Union Carriage and Wagon is now part of the French company Alstom, its legacy lives on in the iconic 17E locomotives that continue to haul trains across the Sishen line.
