Abstract: A train having a protection device with self-adaptive crashworthiness is disclosed, which relates to the technical field of safety protection of trains. The train includes multiple vehicles, a head vehicle is located at the head end of the train, and a head vehicle energy absorbing coupler mechanism is mounted at the front end of the head vehicle, each two adjacent vehicles are connected to each other by a middle vehicle energy absorbing coupler mechanism. An image acquisition mechanism and a radar detector are mounted at the head vehicle for monitoring whether there is an obstacle ahead the train, measuring distance and collision speed between the train and the obstacle, and for transmitting measured data to a processing center of the train, the processing center optimizes and adjusts impact force at the head vehicle energy absorbing coupler mechanism and the middle vehicle energy absorbing coupler mechanisms based on a collision situation.
