“…Then, the use of a listener service reduces the number of request messages sent from each participant when information is not changed, especially when the train is not yet sent, and the interlocking is just on the stage of commanding or forming the itinerary. This meets the optimization of data exchanged aimed by the distributed architecture [12] of calculators and the interoperability between adjacent interlocking.…”

“…The centralized architecture facilitates using centralized supervision as shown in Figure 3, where every interlocking sends information related to its area of control to the global supervisory station called the central command station. The centralized mode allows more functionalities and services like tracking trains' movement, a programmable list of itineraries, or automatic routing [12]. Some of those operations need interaction with the external system using the external server as an interface, but the difficulty of leading such centralized architecture is the need to get all interlocking from the same supplier because of the necessity to manage them from one central server with a common communication protocol.…”

“…The complexity of the architecture of computer interlocking lies not only in the development of its functions and the software structure but also in the adaptation to the geographical context where the software is executed and where the control and supervision are extended [13]. To deal with this complexity, a distributed architecture, accompanying the functional model [7] of computer interlocking has been proposed in [12] based on the recommendations of formal modeling of signaling systems [13]. Our proposal is also concerned with a lightening of the calculation of the central interlocking level and a reduction in the flow exchanged in the local network linking the interlocking to the field equipment [12].…”

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

The technological evolution of signaling systems has created a dependency from infrastructure managers to suppliers and industrials dominating the market. Indeed, for each deployed computer interlocking, the modification of field equipment is required to allow an adaptation with the new interlocking in terms of communication protocols and logical interface. In addition, to ensure safe traffic of trains, the communication of railway signaling data is necessary between interlockings. However, delayed deployments from one station to another make the establishment of communication channels costly and difficult, or even impossible, since each supplier keeps confidential its communication protocols and usually opts for interfacing based on wired logic. This paper presents our approach to a homogeneous architecture of interlocking meeting modularity requirements, interoperability, and logical interfacing between interlockings. This approach relies on a classification of internal functions of the computer interlocking, a distribution of the execution of those functions and making useful information available for interfaces between adjacent interlockings through the IEC 61499 standard coupled with service-oriented architecture (SOA).
