PROBLEM TO BE SOLVED: To provide train radio communication equipment capable of ensuring a good communication state both in an electric field area with high city noise and a low electric field area such as a mountainous area.SOLUTION: The train radio communication equipment prestores correspondence between positional information of a train associated with an electric field intensity of an electric wave of a single frequency from a radio base station device (7) and a noise squelch set value for a noise squelch change circuit 3 included in a receiver, and changes the noise squelch set value according to the positional information of the train from positional information generation units (5, 5a, 5b).SELECTED DRAWING: Figure 1 |
