Signal Aspect Verification
SignalEye uses computer vision algorithms to continuously verify wayside signal aspects from trackside cameras.
Supported Signal Types
- Color light signals (single and multi-head configurations)
- Searchlight signals with color-changing mechanisms
- Position light signals (limited support for pattern recognition)
Detectable Aspects
- Stop/Restricting (Red)
- Approach (Yellow)
- Proceed/Clear (Green)
- Flashing aspects (with temporal analysis)
- Dark signal detection (lamp-out conditions)
Detection Methodology
Edge-deployed deep learning models classify signal aspects in real-time. Models are trained on railroad-specific signal configurations during implementation. Detection confidence scores below threshold trigger alerts for human verification.
Primary Value
Early detection of degraded lamps, misaligned mechanisms, and aspect discrepancies before they impact train operations or trigger false proceed conditions.
FRA 49 CFR Part 236 Compliance Support
SignalEye monitoring data supports railroad compliance with FRA signal system regulations.
Testing Documentation (§236.101-110)
- Continuous camera-based monitoring provides visual verification between required test intervals
- Timestamped records support maintenance documentation requirements
- Historical image archives enable trend analysis for degradation patterns
False Proceed Investigation Support (§236.11)
- Video archives provide evidence for investigating signal aspect discrepancies
- GPS-synchronized timestamps enable correlation with train movement data
- Complete audit trail for signal maintainer review and FRA reporting
Point Detector Verification (§236.6)
- Visual confirmation of switch point position supplements electrical point detector circuits
- Camera-based verification supports maintenance and troubleshooting workflows
- Points alignment imagery for maintenance documentation
PTC Failure Analysis (§236.1023)
- Camera data supports investigation of PTC-related events
- Visual context for wayside equipment condition assessment
- Correlation with PTC system logs for comprehensive failure analysis
Important Limitation
SignalEye is a monitoring system and does not replace FRA-mandated signal testing or safety-critical detection circuits. Railroads remain responsible for all regulatory compliance requirements including mandated inspections by qualified personnel under 49 CFR 236.7.
SignalEye documentation can supplement — but does not satisfy — FRA Part 236 testing and inspection requirements.

Why Camera-Based Monitoring?
Supplement Existing Systems, Don't Replace Them
SignalEye works alongside your existing signal diagnostic systems. Camera-based verification provides visual confirmation that complements electrical monitoring — catching conditions that point-in-time electrical tests might miss.
No Modification to Signal Equipment
SignalEye cameras mount externally with no connection to signal circuits. No signal system downtime for installation, no impact on existing safety certifications, and no additional failure modes introduced to safety-critical equipment.
Visual Evidence for Investigation
When issues occur, video evidence accelerates troubleshooting. Instead of relying solely on diagnostic logs, maintenance teams can see exactly what the signal was displaying when an event occurred.
Flexible Deployment
Monitor individual high-priority locations or scale to full-territory coverage. Camera-based approach allows incremental deployment based on operational priorities without system-wide infrastructure changes.
Works With Any Signal System
SignalEye is signal-system agnostic. Whether your territory uses GE, US&S, Safetran, or other signal equipment, camera-based monitoring works independently of the underlying signal technology.
SignalEye adds a visual verification layer without touching your existing signal infrastructure.
What it does
- Signal aspect verification from wayside cameras (red/yellow/green confirmation)
- Switch position confirmation with anomaly alerts (points alignment, lock status)
- PTC integration for automated fault reporting to dispatch and signal maintainers
- Trend analysis for signal degradation patterns (bulb failures, lens fouling)
- Alert escalation rules by signal criticality and location (interlockings, grade crossings)
How it works
Continuous Capture
Wayside cameras monitor signals and switches 24/7, capturing high-resolution imagery in all lighting and weather conditions.
AI Detection
Edge-deployed models identify signal aspects (red/yellow/green) and switch positions (normal/reverse) in real-time.
State Verification
Detected states are compared against expected conditions from dispatch/interlocking systems.
Anomaly Alerting
Discrepancies trigger immediate notifications — aspect mismatches, degraded lamps, or position variances.
Documentation & Trending
All detections are logged with timestamps and GPS coordinates for compliance reporting and pattern analysis.
