Complex switch turn-out arrangements using proximity selection
DCFirst Claim
1. An automatic method of controlling one or more turn-outs in a branching pathway, said pathway directing the movement of moving objects, the method comprising the steps of:
- providing one of at least two arming signals, each arming signal associated with a path branch direction for one or more turn-outs so as to enable the one or more turn-outs to toggle to a direction corresponding with the provided arming signal;
determining electronically whether or not the turn-out is occupied;
electronically detecting a moving object approaching the turn-out; and
if the turn-out is not occupied by a moving object, automatically toggling the turn-out in response to the object approaching the turn-out without operator intervention;
and then disarming all of the turn-outs so that only the first unoccupied turn-out approached by the object is toggled.

Abstract
A method and apparatus for directing the movement of a train around a model railroad track having one or more turn-outs activated by at least two separate arming signals. Each signal is linked to a specified direction of the turn-outs such as straight, curve right, or curve left. The arming signal is sent to all turn-outs on the railroad track but only the turn-out which the train is approaching is toggled to a position corresponding to the arming signal. All turn-outs over which the train is moving at the time the arming signal is sent are disarmed to prevent the train from derailing due to the toggling turn-out. Proximity-selection switches may also be used for slot-car operation or for city or highway vehicles which are part of a model or miniature diorama within the model railroad layout.

4. A turn-out control system for use with objects moving along a branching pathway having a plurality of turn-outs, the control system comprising:
-
a plurality of detection means for detecting the presence of a moving object, each of the detection means being located at a respective location on the pathway located remotely from a corresponding one of the turn-outs; arming request means for arming all of the turn-outs; means in each of the turn-outs for automatically toggling in response to the indication of the presence of the moving object at the respective location of the detection means on the pathway only if the turn-out is armed; and disarming means for disarming all of the previously armed turn-outs in the pathway when one of the turn-outs toggles.

5. In a model roadway layout, an automatic method of controlling one or more turn-outs comprising the steps of:
-
arming the one or more turn-outs so as to enable them to toggle; and
for each turn-out;determining electronically whether or not the turn-out is occupied by a slot-car; electronically detecting a slot-car approaching the turn-out; and if the turn-out is not occupied by a slot-car, automatically toggling the turn-out in response to the vehicle approaching the turn-out without operator intervention; and then disarming all of the turn-outs so that only the first unoccupied turn-out approached by the slot-car is toggled.

6. An automatic turn-out apparatus for a model roadway layout comprising:
-
a lead-in leg; a curve leg; a straight leg; electric switch means for coupling one at a time of the curve leg and the straight leg to the lead-in leg; detection means for detecting and indicating a vehicle approaching the turn-out; means for arming the turn-out; and means for automatically toggling the switch means in response to said the indication of a vehicle approaching the turn-out only if the turn-out is armed. - View Dependent Claims (7, 8)
