Railways use significant human labour for inspections

Human inspectors still perform majority of visual

track testing by walking the track.

An average inspector covers less than 3 kms of

track testing in one day.

Automation of manual inspection processes is

important for better quality inspections and

measurements as sensors cover more track,

more quickly and provide objective data.

On highly frequented tracks, wear would justify

more inspection but often, there are not enough

slots to do it.

Or expensive measuring vehicles are used,

which are operated outside normal railway

operating hours.

Z series is a sub-ambient cooled singular assembly with integrated

processing, electronics, sensors, lighting and data storage. It scans rail and track bed.

Z series hardware is singular assembly





Z series has minimal inside cabin components

The system can be mounted under a locomotive or carriage, front, back, or in between ends.

It is designed to provide high-quality inspection at speed of 160 km/h.

Z series high res images detect defects early

Rail Vision cameras image track at 0.5mm per pixel or less producing some of

the best quality imagery and measurements, and detect faults early when they

can be repaired at a lower cost.

Vegetation maps

S Series

The detection of vegetation and the measurement of its

clearance is an important S series output. Colour

cameras combined with LIDAR measurements

automatically determine the amount, type and extent of

vegetation growth surrounding railway tracks.

Vegetation maps

S Series

Clearance measurements are reported with track location based on vegetation proximity to the track centreline. Areas in red need to be cut back from the track.

Vegetation maps

S Series

Vegetation maps are generated from measured data to show the extent of various types of vegetation on the track. The position of hazardous trees is shown. The maps are interactive.

Sighting distances

S SeriesS Series equipment makes

sighting measurements for

signals, level crossings and

speed signs. There are strict

rules on what these minimal

distances must be to allow

the driver to brake if

needed.

Automated recognition of

signals, level crossings and

speed signs, is followed by

calculation of their sighting

distances from sensors with

less than 1 meter accuracy.

All signals/ level crossings

and speed signs not

meeting sighting criteria are

highlighted with track

curvature data.
