Services interfaces for interoperability of signaling computer interlocking on borders

<p>Technological developments in the field of railway signaling have allowed more and flexibility management rail traffic, especially with computer interlocking. However, differences principles from one country to another as well structure interlocking software communication protocols depending on suppliers lead interoperability difficulties at borders between Some deployed projects deal issues regarding information train like European traffic system (ERTMS) project. Unfortunately, themselves is still not achieved. ERTMS This article draws up a proposed model for interfacing boundaries based service-oriented architecture (SOA). In addition, ensure coupling SOA services internal functions interlocking, distributed programmable logic controller according IEC 61499 standard suggested.</p>
