TRAVELING TOY SYSTEM

摘要

A traveling toy system in which the position of a self-propelled towing vehicle located under an upper track member can be immediately confirmed. Two annular light transmission regions (5B, 5C) are arranged on the upper track member (5). Light emission means (47) is provided on the self-propelled towing vehicle (21). The two annular light transmission regions (5B, 5C) allows light emitted from the light emission means (47) to transmit through them. When viewed from above the upper track member (5), the position where under the light transmission regions (5B, 5C) the light emission means (47) is emitting light is readily found. Thus, the position of the self-propelled towing vehicle (21) can be simply found by locating the place where light is emitted.
