Integration
One operating platform. Built around your yard.
Pathfinder® gives operators a centralized view of the yard while the ARMMI™ programmable processor connects switch machines, field equipment & communications into one coordinated control system.
Whether you're starting with a single switch or managing an entire terminal, the platform scales with your operation — not the other way around.
Pathfinder
Yard Control Software
One clear view of your yard.
OVERVIEW
Pathfinder provides operators with a browser-based interface for monitoring yard status, controlling field equipment and managing train movements from one centralized location.
Instead of forcing your operation to match generic software, Pathfinder is configured around your track layout, operating practices and business rules.
Standard Yard Control
The foundation of every Pathfinder installation includes the tools required for reliable day-to-day yard operations.
Standard capabilities include:
Switch & derail control
Switch position indication
Occupancy indication
Switch locking
Event logging
Alarm monitoring
Browser-based operator interface
User authorization
Diagnostics & system monitoring
This creates a complete operational foundation that can expand as your yard grows.
Expand when you’re ready.
Pathfinder is offered as a tiered platform that can grow with your operation.
Rather than purchasing functionality you don’t need, additional capabilities can be added as operational needs evolve.
Available expansion modules
NX Routing
Allow operators to select an entrance and destination while Pathfinder automatically aligns and locks the required route.
Additional protection includes:
Route alignment
Route locking
Alternate routing
Flank protection
Sectional release
Terminal performance tracking
Future modules in development:
Additional reporting
Advanced diagnostics
Custom operator displays
Yard-specific workflows
Additional automation features
ARMMI
Programmable Processor
Reliable field control for connected rail yards.
OVERVIEW
The ARMMI programmable processor receives commands from your selected control system — including Pathfinder, push-button controls, handheld radios or other integrated interfaces — and safely executes those commands in the field while continuously monitoring equipment status and returning verified feedback to the operator.
Built for dependable operation.
Rather than relying on generic industrial controllers, the ARMMI is engineered for the unique demands of rail yard automation.
Core capabilities include:
Executes yard control logic
Controls switch machines and derails
Monitors switch position and occupancy
Processes field inputs and outputs
Validates operator commands before execution
Reports live equipment status
Generates alarms, diagnostics & event data
Integrates with Pathfinder and existing yard infrastructure
The result is reliable, deterministic control that gives operators confidence every time a command is issued.
