Other approaches to automatic signals: ‘Trip Tracks’ and ‘Axle Counting’

In an attempt to keep costs down but still have “Automatic Signals” some railroads have turned to systems that do not use “Track Circuit train detection” but rather “Trip Tracks” or “Axle Counting”.  I will discuss why these systems should be avoided if possible. Continue reading

Problems With Traditional Approaches To Automatic Signals

Traditional approaches to automatic signaling use track circuit sensing and relays in a manner similar to full-scale railroads.

In many cases this works fine until longer track segments are required, central monitoring is desired, or you want to add CTC capabilities. Continue reading
