Abstract
A model railway traffic light apparatus, including: at least one signal light; a sensor to detect a timing when a toy train which travels along a rail passes through a predetermined position; and a control section to switch sequentially a series of light turning-on patterns of the signal light and count a period from a first passing of the toy train which is detected by the sensor and until a second passing of the toy train which is just after the first passing and which is detected by the sensor, and to set a switching timing of switching the light turning-on patterns to be variable corresponding to the period.
