Digitalization across the globe has been increasing over the past few decades which has encouraged the deployment of highly automated systems in numerous application such as public transportation, security, safety, and many others. The intelligent railway systems provide several intelligent railway solutions for load detectors, wagon identification, traffic control center systems, routing and scheduling systems. These automated systems minimize the complexities in the railway applications including fault detection, brake system inspection, automated train control, and many other systems. In addition to this, introduction to cloud-based and IoT enabled intelligent railway systems will generate significant over the forecasted period. However, higher initial investments and complexities in integrating these systems with existing systems might stagnate the demand for the same.
