A system for analyzing health of assets in train is provided. The system includes a sensing unit configured to generate health data of sub-assets. The system also includes a controller in communication with the sensing unit to receive the health data. The controller is configured to display, in a graphical user interface (GUI), a list of assets configurable to allow selection of one asset therefrom. The controller is configured to receive an input command, in the GUI, to select a desired asset from the list of assets for requesting information about health of the desired asset. The controller is configured to display, in the GUI, a visual representation of the desired asset, along with the sub-assets, in response to the input command. The controller is configured to flag, in the GUI, the sub-assets in the visual representation of the desired asset based on the health data of the sub-assets.
