ABSTRACT:
This travel direction indicator is for model railroads, and serves to indicate the direction a model train will travel on a track. Primarily, it consists of a pair of spaced-apart optical fiber rods, each having arrow head like indentations, the group on one rod facing in one direction and the other group, of the other rod, facing in the opposite direction. It further includes a panel for mounting the rods, and a switch is coupled to a pair of bulbs in the panel to illuminate each rod selectively, which will indicate the direction a train will travel, by the lighting up of the arrow-like indentations.
