ZTR partnership
Downer holds an exclusive partnership with ZTR in the Australian and New Zealand freight market – enabling customers to make immediate emissions reductions on their journey to net zero.
ZTR is a global leader in sustainable locomotive technology with their entire product range available exclusively through Downer.
Exclusive product range
Aging fleets often face challenges with reliability, diagnostics, and operational efficiency. ZTR's advanced locomotive control system, NexSys, is engineered to address these issues, modernising existing locomotives while delivering reliable performance.
Seamlessly integrating with other ZTR solutions and on-board electronics, NexSys optimises fuel efficiency, improves diagnostics, enhances throttle and traction control, and provides a scalable foundation for future upgrades. With NexSys, operators gain a future-ready, sustainable fleet capable of meeting today’s operational demands.

Locomotives often fail to start due to battery depletion, extreme weather, and heavy operational demands—resulting in costly downtime, increased maintenance, and reduced fleet availability.
KickStart by ZTR is the industry-leading solution engineered to eliminate battery-related start failures, extend battery life, and keep your locomotives ready to perform. Powered by advanced supercapacitor technology, KickStart supports reliable starts in all conditions and reduces maintenance for high-horsepower, long-haul units.
By supplementing batteries during engine start, KickStart reduces energy drain, improves cranking speed, shortens recharge time, enhances cold-weather performance, and boosts overall fleet availability.

SmartStart AESS is ZTR’s intelligent idle-reduction system that automatically shuts down and restarts locomotive engines based on real-time conditions—like temperature, battery voltage, and air pressure. It cuts fuel waste, lowers emissions, and boosts operational efficiency without crew intervention. Trusted on over 10,000 locomotives, SmartStart delivers up to 8,000 gallons in annual fuel savings per unit and pays for itself in under a year.

BOA-II is ZTR’s advanced wheel slip control and excitation system that boosts locomotive tractive effort, protects equipment, and extends fleet life. Designed to retrofit aging locomotives, it delivers up to 80% more traction for DC generators, improves throttle response, and reduces rail wear. With built-in diagnostics and FLEX platform compatibility, BOA-II ensures reliable performance and future-ready upgrades—keeping your fleet on track and operating at peak efficiency.

Pivot is ZTR’s advanced railcar remote monitoring solution that transforms any railcar into a smart asset. Powered by wireless sensors and BlackBerry Radar technology, Pivot delivers real-time insights on location, impact detection, door and hatch status, load condition, and handbrake position. With zero maintenance, long battery life, and rugged durability, Pivot helps rail operators and shippers reduce downtime, protect cargo, and optimise fleet performance, seamlessly integrated with RailPulse and your business systems.
