Frequently Asked Questions
Alta works across freight locomotives, shunters, and supporting rollingstock. Solutions are tailored based on duty cycle, route profile, and operational requirements rather than a single locomotive class.
Yes. Retrofitting existing locomotives is a core focus, allowing operators to decarbonise fleets without full asset replacement.
Alta’s systems can integrate regenerative braking to capture energy during braking and downhill operation, redirecting it back into onboard storage to improve efficiency and extend operating range.
Many solutions are designed to operate within existing rail infrastructure. Additional charging or energy systems can be introduced progressively as projects scale.
Projects usually start with technical scoping and feasibility assessment, followed by a pilot or prototype vehicle. This staged approach allows performance and integration to be validated before any production rollout is considered.
Electrifying Freight Rail
Rail remains one of the most efficient modes of transport for moving freight at scale, yet diesel-powered locomotives continue to dominate heavy rail networks. As decarbonisation targets tighten and fuel costs rise, rail operators are increasingly exploring electrification pathways that can be deployed without compromising reliability or requiring full network overhauls.
Alta supports the electrification of rollingstock and locomotives through battery electric, hybrid, and electric tender solutions purpose-built for heavy freight operations. Our systems are engineered to integrate with existing assets and infrastructure, enabling staged adoption rather than disruptive replacement.
With deep experience across traction systems, power electronics, and energy storage, Alta works with operators and partners to deliver electrification solutions that perform in real operating conditions.
