Micro-Sensor Offers Vibration Sensors for Curve Detection and Derailment Protection for Trains

Berndt Opitz, Development Manager at Micro-Sensor, part of the Micro-Epsilon Group, discusses how high performance sensors are helping rail operators to increase train maintenance intervals by using curve detection and derailment protection with on-bogie vibration measurement.

Micro-Sensor recently supplied curve detection systems for use on high speed trains on the Haramain High Speed Rail Project in Saudi Arabia. These high speed electric passenger trains travel at speeds of up to 300km/h across a 453km network between Medina and Mecca.

For high speed trains that travel at speeds in excess of 160km/h, European rail industry regulations stipulate that these trains must be fitted with suitable derailment safety protection systems. High vibrations resulting from the interactions between the train and the track can potentially cause a carriage to derail.

For the Haramain High Speed Rail Project, Micro-Sensor supplied bogie-mounted vibration sensors for improved derailment protection and curve detection systems to monitor carriage/wagon tilt in curves for better control of lubrication of the wheels during curves in the track. … (read more)
