The Wikipedia citation is correct for contemporary times (the crossing signal time limit of 15-20 seconds is a result of modern noise reduction regulations). For operators of other eras, I found a specific article by Andy Sperandeo for use by modelers going further into horn signals...http://jbritton.pennsyrr.com/downloads/w...ignals.PDF. There may have been additional variations or additions by era or property. Another example, and additional references (from our Canadian friends) includes hand/lantern signals -http://www.tc.gc.ca/eng/railsafety/rules-tco93-163.htm- portable radios haven't been common all that long. I always admire an operator's use of properly employed and executed horn/whistle signals...it adds to the reality of the experience. Bob C.
