The flowchart shows a linear data flow between three connected components. The left rounded text box labeled “Train (Sensors: I R, acoustic, vibration, R F I D)” is shown. A right-pointing arrow connects this box to a central rectangle labeled “Cloud Data Platform”. Another right-pointing arrow from the central rectangle connects to a rounded rectangle on the right labeled “Digital Twin (Virtual Train Model)”.
