The End-of-Train device comprises an audio input unit configured to detect an audio input associated with at least one event, and to generate an audio signal based on the audio input. The event is one of an utterance of a voice command by a railway personnel or an incident that potentially impacts an operation of the train. The End-of-Train device further comprises a memory and a processing unit communicatively coupled to the memory. The processing unit is configured to execute one or more instructions in the memory to analyze an audio input to identify one or more actions to be performed by the End-of-Train device and to initiate execution of the one or more actions identified. Further, a notification may be generated based on execution of the one or more actions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"End-of-train device with audio support","description":"An improved End-of-Train device suitable for mounting on a train is disclosed.
