Many of the PRR-type position light signals are still in service on today's rail lines. Quite a few have been updated to full 3 color aspect signaling. In the position light format, green is vertical, yellow is diagonal and red is horizontal. The center light is usually removed and a blank cover put in its place. Now, Atlas O realistically recreates this signal in miniature. Using the acclaimed 21st Century Signal™ System electronics, prototypical signaling is a reality for your layout. Fuly-compatible with all Atlas O signal products.
