To provide a railway model device which enables a video imaged from a model railway vehicle (2) to be viewed on a monitor (23) without disturbing the color tone in the above imaged video signals regardless of the traveling position of the model railway vehicle (2).

One end (3a) and the other end (3b) of a pair of parallel rail tracks (3) for guiding the travel of the model railway vehicle (2) by an endless track are made to face each other at such a gap that the travel of the model railway vehicle (2) can be guided, the pair of rail tracks (3) are disposed in a closed loop shape, each of one end (3a) of the pair of rail tracks (3) is used as a feeding point to connect an FM demodulation circuit part (6) for demodulating modulated video signals outputted from the model railway vehicle (2), and the terminating resistor (30) of an impedance almost equal to the characteristic impedance of the pair of rail tracks (3) is connected between the other respective ends (3b). The modulated video signals in the opposite direction by being in the closed loop do not reach the feeding point, reflected waves do not appear either by the terminating resistor (30) connected to the divided other end (3b), and the plurality of modulated video signals of different phases are not combined.
