• ALL smartSignals have optical detection built right in.
• They operate in any light from total darkness to sunlight
• No need to cut track for isolated sections
• No need to tear up track and mount finicky mechanical detectors, and
• No need to go out and buy an additional sensor for $20 or more
• Semaphore flags are slow motion
• Lights change by fading out and fading in for added realism
• Automatic time delays – 4 sec. from RED to YELLOW and then 3 sec. from YELLOW to GREEN
• Input and output connections for added flexibility
• All signals are scale size – available in O, S and now G gauge
• All you do is put them on the layout and supply power. smartsignals do the rest.
