Custom Solutions

Bogie-Mounted Track Geometry & Machine Vision Inspection System

At Andian Technologies, we’ve developed a state-of-the-art, permanently mounted inspection system that redefines how railway infrastructure is monitored and maintained. Engineered to integrate seamlessly onto a bogie, this advanced platform combines precision track geometry measurements with high-resolution machine vision capabilities—delivering continuous, real-time insights without disrupting normal rail operations.

Key Features:

  • Permanent Mounting: Designed for long-term installation on operational rolling stock for seamless data collection.
  • Track Geometry Measurement: Accurately monitors parameters such as alignment, cross-level, gauge, and twist.
  • Machine Vision Integration: Captures and analyzes high-speed video of the track structure, fasteners, joints for defect detection and asset inventory.
  • Real-Time Analytics: Enables early identification of track defects, improving maintenance planning and safety.
  • Low Maintenance Footprint: Robust design with minimal maintenance requirements, built for harsh railway environments.

Applications:

  • Mainline and transit rail networks
  • Automated condition monitoring
  • Predictive maintenance programs
  • Infrastructure asset management

Impact: This system empowers rail operators with continuous, automated infrastructure evaluation—reducing inspection costs, improving track safety, and supporting smarter, data-driven maintenance decisions.

Towable Track Geometry Inspection Cart with Third Rail and LIM Measurements

Andian Technologies has developed a compact, high-precision inspection cart designed to be towed by any rail-bound vehicle. This versatile platform performs comprehensive track geometry measurements and includes integrated sensors for evaluating third rail and Linear Induction Motor (LIM) rail alignment, making it an ideal solution for both conventional and electrified rail systems.

Key Features:

  • Towable Design: Lightweight and rugged, the cart is easily deployed by rail maintenance vehicles or trains, requiring no complex setup.
  • Comprehensive Track Geometry: Measures critical parameters including gauge, cross-level, alignment, and twist to ensure infrastructure integrity.
  • Third Rail Inspection: Captures height, lateral position (stagger), and gauge of the third rail to support power delivery system maintenance.
  • LIM Rail Measurement: Accurately monitors LIM rail height and position for systems using linear induction propulsion.
  • Modular Sensors: Customizable sensor package to meet client-specific measurement requirements.
  • Data Logging & Visualization: Real-time data acquisition with on-board or remote display options for efficient field diagnostics.

Applications:

  • Transit systems with third rail or LIM infrastructure
  • Light rail and automated people mover systems
  • Routine geometry inspection in areas with tight access or low clearance
  • Supplement to larger, vehicle-mounted inspection platforms

Impact: This cart offers a cost-effective, flexible inspection solution for transit agencies and infrastructure maintainers, enabling safer, faster, and more targeted maintenance of both conventional track and electrified rail systems.

Case Study: Custom Track Geometry System for 36″ Narrow Gauge Railway

Client Challenge
A client operating a 36″ narrow-gauge railway needed a reliable way to inspect and maintain their track infrastructure. Their network, used for both passenger and industrial service, lacked the resources and space for traditional, full-size inspection vehicles. Off-the-shelf solutions built for standard gauge were incompatible or required costly, time-consuming modifications. The client needed a compact, purpose-built system that could deliver accurate measurements and withstand rugged operating conditions.

Our Solution
Andian Technologies partnered with the client to design and deliver a fully custom track geometry inspection system specifically for 36″ gauge rail. We engineered the system from the ground up to meet the unique requirements of narrow-gauge operation such as taking into account clearance limitations, vehicle weight restrictions, and the specific geometry standards of the line.

The system included:

  • Precision measurement of gauge, cross-level, alignment, and twist
  • A compact, lightweight design optimized for narrow-gauge track vehicles
  • Robust construction for operation in challenging terrain and weather
  • Configurable data output formats for integration with the client’s existing maintenance workflow

Results & Impact
The custom system gave the client a dependable, efficient means of tracking and maintaining their infrastructure condition. With accurate geometry data now readily available, maintenance crews were able to:

  • Proactively identify and address issues before they became safety concerns
  • Reduce manual inspection time and labor costs
  • Extend the service life of key assets through informed maintenance planning

Ultimately, the project demonstrated how tailored engineering can bridge the gap between modern inspection technology and legacy or specialty rail networks. The client now operates with greater confidence in their track safety and own a platform that can grow with their evolving needs.
