Line 12:

On Bi-directionally signaled lines two "shoes" would be needed, one for each direction of travel as locomotives would only have a sensor to detect the shoes on one side of the train. The receivers can also be designed for easy removal to prevent damage when operating in non-equipped territory or to cut costs when only only a small amount of railroad requires ATS equipped locomotives. "Inert" inductors are sometimes placed in advance of certain speed restrictions to deliver a non-conditional or at engine terminals to test the functionality of the ATS system.

On a few [[light rail]] lines IIATS has been employed in a manner similar to mechanical train stops, stopping the train if it passes an absolute stop signal. It is useful where light rail shares tracks with mainline railroad trains as mechanical trips may be damaged by or interfere with freight operations and because [[light rail vehicle]]s can be boughtbrought to a stop much more quickly than a mainline railroad train without requiring complex [[Overlap (railway signalling)|signal overlaps]]
