I've been intensely studying various signal systems for the past few months. I've learned a lot here and elsewhere, but I ran across something the other day that I hadn't seen at least here in the U.S. On The Position Light Blog, http://position-light.blogspot.com/2014 ... -safe.html" onclick="window.open(this.href);return false; in that post, the first image, I see dwarf signals that look like they face toward the crossover. Are these exit signals? If they are, are they to give a signal aspect for a train exiting the interlocking from a diverging movement? If not, then what are they for? The exit signals do make sense to me, as I recall, there are some signal rules that require approaching the next absolute signal prepared to stop, and in theory, it would make sense to provide an aspect to go ahead and let the train upgrade its speed rather than crawl along prepared to stop at the next signal. If not, then I have no clue.
