Track Materials Inspection System (RL series)

Significant reduction in night
work and visual inspection work!
The system offers automatic inspection for track materials such as ballast,
sleepers and fastening bolts using height image obtained
by high speed 3D acquisition unit with laser and 3D camera.
It supports raising work efficiency and labor saving for track materials inspection.

Joint development with JR Central‘Track Materials Inspection System'
～First system in Japan！
Measuring the condition of track materials while
the Tokaido Shinkansen is running at high speed～

Key Features of
the system

point

01

Flexible Installation

Depending on operational needs, the unit can be installed on hand trolley, maintenance vehicles and in-service trains.
point

02

Automatic Detection of Track Defects

The system automatically detects:
Loose or missing fastening bolts
Ballast collapse or insufficient ballast volume
Sleeper positioning abnormalities
Detected defects are listed and visualized for easy review.

03

Reliable Measurement
in both Day and Night time

Thanks to the combination of optical filters and infrared lasers, the system is unaffected by sunlight and can perform stable measurements both during the day and at night.

04

Simultaneous Brightness and Height Imaging

Even during high-speed operation, the system simultaneously captures high-resolution brightness and height images, ensuring accurate inspection under demanding conditions

05

High-Speed Data Processing

Large volumes of image data are processed rapidly using advanced image-processing technology, enabling smooth, stress-free analysis.

Driving Digital Transformation
in Track Maintenance

Automated inspections are realized by using imaging units, eliminating the need for manual visual inspections performed by workers during nighttime or non-operational hours. All captured image data is analyzed through dedicated analysis software.

Key Strengths of the RL Series
Rail Material Inspection System

1Extensive line up！

The compact measurement unit enables flexible customization for installation on various platforms, from in-service and inspection vehicles to light vehicles such as trolley cars and rail bikes.
2High‑resolution images

Brightness images and height images are captured simultaneously.
Depending on the imaging speed, high-density data acquisition at intervals as fine as 1 mm is also possible.
3Suitable for on-site visual inspections as well

The optional high‑resolution 2D color line camera provides clear visualization of markings and track materials, enabling replacement of on-site visual patrol inspections.

Track Materials Inspection Software
【Track Analyzer】

Track Materials Inspection Software

Just 2 min per 1km analysis!!
The software detects loosening, lack of bolts, sleepers and ballast amount automatically.
You can analyze large amounts of image data without stress because of high speed image processing technology.
Based on height data, the system specifies the defects of track materials by setting limit to criteria.
