SZCZ, le gestionnaire d'infrastructure de la République tchèque, a commandé à SMA des licences et des formations Viriato. Celles-ci seront utilisées pour réaliser la planification stratégique de développement à long terme du réseau ferroviaire à grande vitesse, et comme outil pour établir leurs livrables pour le processus de planification « Timetable Redesign » (TTR), y compris la stratégie et les modèles de capacité. Ces éléments du processus TTR sont un ensemble de plans et de démarches où les souhaits des entreprises ferroviaires voyageurs et fret peuvent être équilibrés avec la capacité disponible du réseau, y compris les restrictions temporaires de capacité (TCRs) planifiées pour les travaux d’infrastructure. Grâce à ces processus, Viriato fait désormais partie intégrante de la planification de SZCZ.

We are pleased to announce that the Autumn 2024 Viriato Standard and Enterprise releases have been delivered to our customers.

In addition to the ongoing performance and stability improvements we continuously undertake to improve Viriato, and the implementation of customer specific functionality delivered in their own program versions, the following features are some specific highlights of this product release available to all:

• This release switches to the Microsoft .NET 8 framework. This provides the long-term assurance that Viriato is maintainable for the future.
• To improve security, all program components are now digitally signed with a digital certificate to guarantee the authenticity of the software.
• The railML 2.2 importer handles defined remarks in the train path and timetable nodes, and the route finding has been improved for trains without section information allowing a choice of routing strategies.
• Microscopy on Demand has been extended to include new user selectable behaviour when the microscopic and Viriato models have differences. Also, when working with different infrastructure variants in Viriato Enterprise the conflicts and block occupations indicate whether they belong to the same infrastructure or not. MoD is also now fully functional in Viriato Enterprise and can be linked with different microscopic models for alternative infrastructures.
• In the robustness analysis the primary delay evolution of a robustness analysis run can now be exported to a spreadsheet with the existing outputs.
• A new platform assignment funder module has been added which can search for conflict free platform assignments in stations for existing timetables. This optional module also requires a separate Gurobi licence.

We are pleased to announce that the Spring 2024 Viriato Standard and Enterprise releases have been delivered to our customers.

• In addition to the ongoing performance and stability improvements we continuously undertake to improve Viriato, and the implementation of customer specific functionality delivered in their own program versions, the following features are some specific highlights of this product release available to all:
• Timetable remarks can now apply to the whole train and be overridden for individual portions of the train run.
• The Viriato Enterprise mini calendar has now be reorganised so that the functions take up less screen space to improve usability.
• TAF/TAP-TSI fixed nodes can now be defined, and a plausibility check is available to ensure that the user has complied with the rules that trains should be planned to stop at these nodes.
• TAF/TAP-TSI lead RU’s can be updated for multiple trains in bulk.
• TAF/TAP-TSI relevant information has been added to the railML export.
• When importing trains using railML and the data contains differences between the infrastructure in the railML and the Viriato database, the user now has more options for how to treat the missing nodes to ensure that the imported trains are valid in Viriato.
• Rolling stock definitions now have a dated validity, allowing improved management of rolling stock by creating multiple versions of a vehicle which differ in certain attributes.
• In the customer timetable it is now possible to see which operational trains form a commercial train.
• In the graphic timetable and platform occupation views, the line number of a train can now be displayed as a label.
• In the platform occupation view when viewing a topology, the direction of train movements has been clarified with arrows, and the ability to select trains which overlap on the diagram has been improved.
• In Microscopy on Demand (MoD), the use of mixed models where part of the infrastructure is mapped to a microscopic model in an external system, and the remainder of the infrastructure is only mesoscopic has been implemented. This enables the use of larger models and the focusing of detailed effort on areas of specific interest.
• In MoD, the display of signals and stopping points has been added to the topology viewer.
• In the trip time analysis module, when working with commercial trains it is now possible to open these trains from the analysis view.
• The running time calculator now has a user configurable default speed for the case where the speed profiles are not fully defined.
• The robustness analysis can now be carried out only for a specific region of the Viriato infrastructure, allowing the user to focus on the area they are studying without having to model the entire network with the consequential performance implications.
• The path search module now includes additional settings allowing finer control over how the conflict free paths are found. These include settings which control how much additional time can be added to a train run, whether reserves should be kept for performance purposes, the ability to ignore capacity restrictions in nodes where the user believes sufficient capacity will be available regardless of the analysis, an problem analysis mode which identifies the nodes with insufficient capacity when conflict free paths cannot be found and the improved selection of multiple trains for the case where the user is inserting different trains sequentially into the timetable.
• The train conflict report in the conflict detection now considers infrastructure variants and versions when working in Viriato Enterprise.

Le système de planification des sillons Viriato est en service depuis bientôt 25 ans au sein de DB Regio AG et DB Fernverkehr AG. Le contrat pour la maintenance et le développement continu de Viriato Enterprise vient d’être prolongé pour huit années supplémentaires. Viriato est aujourd’hui utilisé par les deux entreprises ferroviaires à de nombreux horizons de planification (planification pluriannuelle, horaire annuel, adaptations sous-annuelles), dont l’élément central reste la commande de sillons pour l’horaire annuel auprès de DB InfraGO AG et la transmission des contrats d’attribution de sillons aux processus avals.

Les CFF utilisent Viriato pour leur planification à long et moyen terme depuis 2003. Le contrat de maintenance pour Viriato Enterprise vient désormais d’être étendu pour les quatre prochaines années. Dans le cadre de sa planification à long terme, les CFF utilisent Viriato pour le design de son réseau ainsi que le développement des étapes d’aménagement et stratégies d’utilisation du réseau (STUR) sur mandat de l’Office Fédéral des Transports (OFT). Dans le cadre de sa planification à moyen terme, Viriato est utilisé pour le développement de concepts d’horaires travaux ainsi que, toujours sur mandat de l’OFT, les plans d’utilisation du réseau (PLUR). Le dernier PLUR approuvé par l’OFT a servi de fondation à la stratégie de capacité TTR pour l’année correspondante.
