An indication of the situation is made and an alarm is issued.
Therefore, since the display device / alarm device 33c informs passengers in the train that an abnormal situation has occurred in the train, the driver suddenly brakes and the train, train, etc. decelerates rapidly. In this case, passengers can be prevented from falling.

Further, the train is provided with an abnormality determination circuit 38b that detects the operation of the brake 38a and determines whether an abnormal situation has occurred. In this case, it is determined whether or not the brake is an emergency brake from the operating state of the brake. If it is determined that the brake is an emergency brake, it is determined that an abnormal situation has occurred, and an abnormal signal is transmitted via the control device 35 and the transmission device 34. An abnormal signal is sent to the line L.
The receivers 11, 21, 31 can also receive this abnormal signal, and an emergency situation occurs in the train command room 10, the station office 20, and the display / alarm devices 13, 23, 33 a, 33 b, 33 c of the train 30. Is displayed and an alarm is issued.
