Provided is a contactless information transmitting apparatus for railway vehicles. The contactless information transmitting apparatus for railway vehicles comprises: a communication unit which is connected to a train comprehensive information apparatus and transmits information to other railway vehicles; a sensing unit which senses the coupling state of a connector for a connection with other railway vehicles and activates the communication unit; and an antenna which is connected to the communication unit and transmits information to other railway vehicles in a wireless way. According to the above composition, the present invention does not need an operator for building an interface when railway vehicles are separated and combined, can reduce time taking for the separation and the combination of the railway vehicles, apply to the existing railway vehicles having no composite connector, and prevent a contact error of the electric communication lines caused by the stepped difference or the removing of a connection cable, thereby reducing communication troubles. |
