thumb|Two detector signs in operation Placement is rather difficult, since you need to use pairs of detector signs, one on both ends of the track to detect. The detector signs have to face each other, or they will have a hard time finding each other. Both signs are operated simultaneously, so you can use both ends to toggle a lever, using 4 statements in total. By adding multiple detector signs underneath one track you can expand the amount of statements.
