A first antenna group includes one first antenna disposed at one end of a leading car, and another first antenna disposed at one end of a following car. A second antenna group includes one second antenna disposed at the one end of the leading car, the position where the one second antenna is disposed being different from the position where the one first antenna is disposed in a direction orthogonal to a travel direction of the leading car, and another second antenna disposed at the one end of the following car. A measurement unit measures radio wave strength between a pair of first antennas during communication via the first antenna group. A controller is enabled to make a switch from the first antenna group to the second antenna group when the radio wave strength is less than a predetermined value.
