The application discloses a track crossway display apparatus. The track crossway display apparatus comprises a main circuit and a control circuit. The main circuit comprises a straight road display branch circuit, a crooked road display branch circuit and a straight road-crooked road switching member. The control circuit comprises a relay and a mercury switch used for controlling the relay to be turned on/off. A magnetic coil of the relay is disposed close to the straight road-crooked road switching member, and used for controlling the straight road-crooked road switching member to turn on one of the straight road display branch circuit and the crooked road display branch circuit. The mercury switch is disposed on an operating handle of a track crossway hand-operated valve. On the premise that track crossway conditions can be clearly displayed, the manufacturing cost of a display device of the track crossway display apparatus can be reduced, the failure rate is reduced, so the maintenance cost can be reduced, and the work efficiency can be raised.
