NexSys – Advanced Locomotive Control System

Unlock next-generation control, automation, and fuel savings with a smarter onboard system

NexSys is ZTR’s next-generation locomotive control system built to modernize fleet performance, reduce fuel waste, and enable intelligent automation. Whether you’re upgrading legacy units or building new, NexSys combines reliable engine control with intelligent features that deliver immediate operational value.

Designed for real-world rail environments, NexSys improves crew experience, simplifies troubleshooting, and ensures your locomotive performs optimally across all conditions.

Why NexSys?

ZTR has more than three decades of experience modernizing locomotives across North America and globally. NexSys is the result of that expertise—offering a robust, modular platform that replaces outdated systems with smarter, integrated functionality.

Key Features

ZTR touch screen control panel with digital display.

Integrated Locomotive Display (ILD)

The Integrated Locomotive Display (ILD) is a powerful in-cab interface that enhances NexSys functionality by bringing critical data directly to train crews and maintenance teams. Designed for simplicity and impact, ILD helps improve locomotive safety, reliability, and operational efficiency.

Key Capabilities:

  • Graphical display of alarms, digital status icons, and real-time alerts

  • Digital gauges and speedometer with advanced over-speed warnings

  • Integrated advanced alerter and train length counter for situational awareness

  • Communication with HOTD and NexSys for enhanced diagnostics

  • Intuitive interface for fault visibility, system health, and data access

SmartStart Automatic Engine Stop-Start

Automatically shuts down and restarts the locomotive based on key conditions, saving fuel and reducing emissions.

Modular Hardware Platform

Automatically shuts down and restarts the locomotive based on key conditions, saving fuel and reducing emissions.

Advanced Battery Monitoring

Real-time tracking of voltage and charge health to avoid failed starts and battery degradation.

Remote Diagnostics & Alerts

Easily integrates with Vision platform for fleet-wide visibility and proactive issue detection.

Improved Adhesion Control

Boost traction and performance, especially under low-adhesion track conditions.

How It Works

1

Assess & Configure

We assess your fleet and operational goals, then configure NexSys to match your power unit specs and system requirements.

2

Install & Integrate

ZTR-certified technicians install the hardware and integrate with key locomotive subsystems including throttle, air, and engine control.

3

Train & Operate

Operators and maintenance crews are trained on the NexSys interface and workflows to ensure smooth adoption.

4

Monitor & Optimize

With NexSys and Vision integration, you gain ongoing visibility into locomotive usage, idle time, and system performance.

NexSys - Remote Connectivity and Diagnostics

Smarter Locomotives. Smarter Decisions.

NexSys connects to the ZTR Vision platform to provide near real-time visibility into locomotive health, idle time, and fault diagnostics. Remote access enables maintenance teams to identify issues early, perform remote troubleshooting, and reduce unplanned downtime. This integration simplifies fleet management and ensures data accuracy across all units.

Features & Benefits

Remote System Monitoring

Access live data on engine hours, idle time, battery status, and fault conditions

Diagnostic Alerts

Get notified of critical issues before they cause unplanned downtime

Idle Analytics

Track idle patterns across your fleet for targeted efficiency improvements

Historical Trends

Analyze performance over time to support maintenance planning and operational strategy

Fleet-Wide Visibility

Centralized view of all NexSys-equipped locomotives, anywhere, anytime

With Vision, NexSys becomes more than a control system—it becomes a strategic tool for continuous improvement.

Add-Ons

NexSys works seamlessly with other ZTR technologies to extend control, reliability, and system insight:

KickStart®

Starting assist system that ensures reliable engine cranking and reduces battery strain

SmartStart® IIe

Enhanced AESS solution with advanced shutdown logic and configurable restart parameters

Event Recorder

Capture and store critical locomotive data for compliance, analysis, and incident investigation
