A Support System for Early Resumption of Regular Train Operations Applying Public Earthquake Information

In this paper, a working model system is presented for estimating seismic activity and aiding decisions on early resumption of traffic following an earthquake. The system uses information from railway operators' seismographs and quasi-real-time public data sources to estimate the distribution of the shake over meshed planes. The seismic motion can be then be extracted at any chainage point along the target railway section.
