W&H MAIN YARDS: The Signal Guide
This page is a guide to various signal aspects you might encoutner
on a raiilroad operating in the 1950s. The indications have not
changed much, but those changes that have taken place are noted
by the date they were last confirmed to be in the rules. The
reditions of the signals are approximate
for some of the less common types. Larger, usually colored lights
indicate an illuminated lamp as where smaller white lights indicate
probable locations of unilluminated lamps.
