Electrifying Rail for a Sustainable Future
Freight locomotives powered by diesel account for 95% of rail’s Scope 1 emissions, making rail one of the biggest opportunities for decarbonisation. But transitioning to cleaner energy isn’t just about meeting regulations—it’s about future-proofing rail operations with sustainable rail solutions that reduce costs, improve efficiency, and lower environmental impact.
At Alta, we’re part of the shift towards electrification in railway, providing railway electrification systems and electric traction systems that integrate seamlessly with existing infrastructure. Our solutions help extend route distances, enhance energy efficiency, and make the transition to a low-emission rail network more achievable.
Proven Railway Electrification That Delivers Results
With over 30 years of experience, Alta has played a key role in railway electrification projects worldwide. Our electric traction systems were first used in China’s quasi-high-speed rail (200km/h) and have since become a core part of its advanced high-speed rail network.
Designed for reliability, Alta’s traction power systems ensure smooth operation in all conditions—including the extreme temperatures Australia’s freight lines endure. By combining precision control, smart energy management, and durability, we’re making railway electrification more efficient than ever before.
Making Freight More Efficient With Smart Electrification
Rail freight is the backbone of logistics, and electrification in railway is key to making it cleaner and more cost-effective. Alta’s traction power systems are designed to integrate with regenerative braking technology, which captures energy from braking on downhill gradients and redirects it to recharge the battery.
This not only reduces the need for external power but also cuts emissions and improves efficiency—helping rail operators take a big step towards sustainable logistics solutions.
Leading the Way in Hybrid & Electric Locomotives
Alta’s Battery Electric Tender (BET) project is setting new standards for electrification in railway by integrating hybrid electric systems with regenerative braking. In collaboration with Aurizon—Australia’s largest rail freight operator—we’re retrofitting a 2300-class locomotive with renewable battery technology.
This is more than just an upgrade—it’s a blueprint for the future of sustainable rail solutions, proving that existing fleets can transition to low-emission rail transport without massive infrastructure overhauls.
