That one may be good in theory, but upon checking the specs, the nominal reflective distance is only slightly over 1/8 of an inch. A better one, and a complete circuit is available through TCH Technologies. It has a reflective range of about 2 inches and will easily detect rolling stock passing overhead ..... and it's only $7.95 ready to go ....
