Reduce Fuel Waste and Unnecessary Idling

Reduce Fuel Waste and Unnecessary Idling

Why Fuel Waste and Excessive Idling Remain a Costly Problem

Fuel is one of the largest operating expenses in rail. Locomotives often idle for hours at terminals or during dwell periods. The most common reasons why locomotives are left idling:

Rail operators need to meet evolving environmental standards while controlling costs—but they can't sacrifice readiness or performance.

Why?

1

Locomotives left running between assignments waste fuel even during non-operational hours.

2

Cold Weather Operations

Idling to prevent engine freezing can be minimized with smarter condition-based controls.

3

Yard Switching

Yard switchers often run for long durations with minimal motion, creating opportunities to reduce runtime.

4

Remote Locations

In areas with no on-site personnel, automatic shutdown/startup logic ensures reliability and readiness.

The unnecessary idling leads to:

The ZTR Solution

It starts with a locomotive sitting idle at a yard terminal.

In most fleets, this engine would keep running—burning fuel, generating emissions, and adding wear to the engine.
With SmartStart® AESS on board, the locomotive is automatically monitored in real time. When engine coolant temperature, air pressure, and battery voltage meet the right thresholds, SmartStart shuts the engine down—safely and intelligently—eliminating hours of unnecessary idling.
The result? Instant fuel savings and reduced emissions. And no crew intervention needed.

But what about extreme weather and restarts?

Freezing temperatures or remote locations make automatic restarts risky. That’s why this locomotive is also equipped with KickStart, ZTR’s starting assist and battery management technology.

KickStart stores and delivers a powerful energy boost during cranking, ensuring every restart is reliable, even in the harshest conditions. It also relieves stress on batteries, extends their lifespan, and reduces the need for idling solely to charge them.

Now the engine starts only when it has to—and it always starts when it needs to.

For larger fleets, SmartStart is just the beginning.

Railroads looking for deeper automation and control choose NexSys, ZTR’s advanced locomotive control system. It includes SmartStart by default, but goes much further—offering intelligent engine management, customizable idle rules, performance optimization, and support for KickStart integration.

With NexSys, railroads gain fine-tuned control over how and when each unit shuts down, restarts, and consumes fuel—while also preparing older locomotives for modern, efficient operations.

Whether you manage tank cars, boxcars, or flatcars—real-time impact data helps you protect your assets and the cargo they carry.

And behind the scenes, Vision connects it all.

As locomotives operate, ZTR’s Vision platform collects and analyzes critical data—idle durations, restart events, location patterns, and fuel use. With easy-to-read dashboards and fleet-wide reports, operators gain real visibility into:

  • How much fuel is being saved
  • Which locomotives idle more than others
  • When and where SmartStart engages
  • Opportunities to optimize further

Vision turns automation into insight-driven fleet management—so improvements don’t stop at installation. They evolve with your operation.

The result?

Smarter shutdowns. Reliable restarts. Better battery health. Real-time insight. Lower fuel bills. And fewer emissions.

This is the ZTR approach to idle and fuel management—designed for efficient rail operations and proven across thousands of locomotives worldwide.
