PURPOSE: A train communication network system is provided to stabilize a network by minimizing the number of connecting lines. CONSTITUTION: A cab signal device unit(20) connects a first MVB(Multifunction Vehicle Bus) network bus and a second MVB network bus. The cab signal device unit communicates with a train integrated management device through an MVB communication method. A screen display device(30) connects the second MVB network bus. The screen display device communicates with the cab signal device unit in the MVB communication method. A wireless communication unit(40) connects the second MVB network bus. The wireless communication unit communicates with a cab signal device in the MVB communication method.
