REFER has been developing and using a wide range of technological tools whose main aim is to enhance the safety of the railway infrastructure. These include geotechnical risk charts, the system of detecting embankment breakage, the system for detecting obstacles at level crossings, the system for detecting wheels and axle boxes of abnormally hot railway carriages, and the system for monitoring the circulation of rolling stock in terms of verifying the real weight of the vehicles and the mechanical impact of the wheels on the track.

Statistical information regarding railway activities is collected and processed daily, which makes it possible to identify any anomalies that may have occurred within the network, facilitating measures to eliminate and monitor risk factors.

Accidents and incidents which impact on railway circulation are also carefully analysed, in order to determine and rectify the respective causes.

REFER also has emergency plans for its railway lines and contingency plans to implement railway rescue services.
