Engineering solutions shaping safer railways.

Hot Spot Axle Detection System

It is a critical trackside safety device designed to automatically monitor train bearings as they pass by. Using infrared sensors, it scans the temperature of every axle box to identify any signs of overheating—an early indicator of bearing failure. If an overheating bearing goes undetected, it can lead to a catastrophic axle failure and potential derailment.
The system works by having trackside computers analyze the temperature data in real time, comparing each bearing against the ambient air temperature and the readings from other axles. If a bearing is critically hot, the system instantly alerts the driver to stop the train; if it is merely running warm, a report is sent to maintenance for future repair. By catching these issues early, the HADS prevents derailments, enables predictive maintenance, and ultimately ensures the safety of cargo.

Intelligent Field Devices

An IFD is a simple instrument used to measure and display the level of water. It combines a sensor with an enclosure (the display, brain etc,..) to provide a direct, local reading of how much water is present.

• Water Tanks: Household overhead tanks or rural water supply systems to check how full they are.

• Rivers, Wells and Boreholes: Measuring the depth to the water table.

• Fuel Tanks: Often used for diesel storage (though strictly for fuel, the principle is identical).

Portable Train Detection System

POTA is a portable, battery-powered warning system that protects railway track maintenance workers by detecting approaching trains and giving them an early warning.

The Setup:
The POTA system works in six simple steps. First, the Detector Unit placed about 1 kilometer away constantly sends a radar beam across the track. When a train enters this beam, the radar detects the large metal object. The unit's onboard processor then verifies it is actually a train and not an animal or bird. Once confirmed, the Detector instantly radios the Worksite Unit with an alert: "TRAIN APPROACHING!" The Worksite Unit immediately blasts a loud siren (over 100 decibels) and flashes bright LEDs. Workers hear this alarm and move to a safe place before the train arrives.
