Real-Time Rail Asset Overview Dashboard

This comprehensive dashboard provides users with an up-to-the-minute view of their rail assets. It features an interactive map that dynamically updates with the GPS coordinates of trains in motion, offering a clear visual representation of their railway lines. Each asset on the map is marked with a color-coded status icon, indicating its current operational state, including active status and any alerts or error messages.

The dashboard comprehensively displays the overall status of various asset categories, such as trains, crossings, tracks, maintenance vehicles, and substations. It also highlights all active recommendations generated by the system’s rule logic. This includes critical alerts like exceeded bogie wear thresholds, ensuring immediate attention to potential issues.

Additionally, the dashboard includes a detailed graph that tracks maintenance requirements across assets. It prioritizes assets based on their upcoming service needs, facilitating efficient maintenance scheduling.

Each section of the dashboard is designed for deeper exploration. Users can drill down into specific asset and recommendation details, gaining granular insights and enabling targeted actions based on the system’s recommendations. This level of detail ensures that users can make informed decisions quickly and maintain optimal operational efficiency.
