To eliminate a manual switch operation for point switching from operation of automatic running of railway model vehicles in a same direction on a rail layout called as reverse.

Combined with a DC power output polarity automatic switching device for railway model running, when a railway model vehicle passes a gap from a block and enters the next block during running, a train entering signal is received, and a train entering signal outputted from the DC power output polarity automatic switching device for railway model vehicle running is detected, a relay is actuated by a relay control circuit, positive/negative polarity of electric potential fed to a driving coil for point switching assembled with each of a plurality of points comprising a railway is exchanged and fed to realize automatic running of railway models in a same direction on a railway laid out into a shape including a plurality of reverses by a means to switch some to the main line and some to side lines.
