First preventive seismic warning system on the Rome-Naples line

As part of the scientific and technological collaboration that has been going on for about 7 years between the Seismology Laboratory of the Frederican Department of Physics and Rete Ferroviaria Italiana - RFI, the national company that manages rail traffic on the national territory, announced the commissioning of the first preventive seismic warning system (early warning) on the Rome-Naples line.

Frederick researchers contributed in the conception, prototype development and implementation of a highly innovative and technologically advanced earthquake early warning system.

Using a network of accelerometer stations installed along the route, the system is able to detect the first seismic waves (P-waves) and estimate the intensity of an earthquake in real time. Within seconds, the system automatically intervenes in rail traffic, slowing or stopping trains approaching dangerous areas, thus ensuring maximum safety for passengers and operators. After the necessary technical checks, RFI staff will be able to reactivate circulation via a dedicated dashboard.
The project is the result of an international collaboration involving not only the Physics Department of Federico II University and RFI but also the Japanese Railways Research Institute JR RTRI.

In the video available at RFI's linkedin page , the operating principle and application of the EW system for rail traffic control is explained.
