Reply to "AF 695 Reverse Loop Relay"

The switch will have to be changed when the last car clears the switch.  A separate track detector could be setup to detect the last car or the switch machine just be throw by manual operation the normal electric switch control button. AF switches are not normally non-derailing like most lionel 3 rail switches.  The 695 changes the polarity of the loop track to that of the current switch direction. The 695 has no way to detect occupation of the loop track, It is just a relay for track power switching. Hope this helps.
