Abstract: A software tool and an electronic interface facilitate model railroaders in initiating, monitoring and directing the path trains (i.e. engine and rail cars) will traverse on the model layout. The software tool and an electronic interface are connected to one of the I/O ports of a computer. The display presented on the computer monitor will mimic the model railroad layout depicting each track turnout with a red or green path. The green path depicts the selected path through the turnout while the red path is the deselected path. With all turnouts displayed simultaneously the condition of the layout relative to train movement can be seen at once by following the green paths. To change the path through a turnout, the user places the cursor on the representation of the turnout on the computer display and performs a left mouse button click. The software will recognize the particular turnout selected and cause a momentary actuating signal to be sent to the tracks turnout motor through the electronic interface.

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.

Abstract: If a vehicle fitted with a head station is to be mechanically and electrically coupled to other vehicles, attention must be paid to the alignment of the vehicles and the coupling condition of the high frequency plugs interconnecting the vehicles. In order to reduce the labor and time required in the high frequency coupling of the vehicles, each vehicle, except for the one with the head station, is fitted with a vehicle station which is connected to the ends of the vehicles via paired high frequency lines by plug-in components. Before the high frequency signals are switched through in a vehicle, the vehicle station checks whether there is a high frequency signal and whether or not the plugs are coupled.

Abstract: An electronic control system for model railroads incorporates electronics which "arms" all railroad track switch turn-outs (here after referred to as "turn-outs") at once, selects and toggles the state of a specific turnout by the approach of a model train directly after arming, and "disarms" all the turnouts at once when the selected turnout has operated. A variation of this method is also applied to model railroad electric uncoupler track sections or automatic unloader track sections to arm, select, operate and then disarm any desired track section.

Abstract: A switch machine operates a track switch under radio control via a switch controller. The switch controller may be given an identifying address unique to it which distinguishes the switch machine from other switch machines in the railway territory. In addressing or programming the switch machine, a portable terminal is used. The controller is enabled by a manually actuable switch to accept identifying addresses which is stored in electrically erasable programmable read-only memory (EEPROM). Whenever a message is received over the radio link, the identifying address is read out of memory. In order that the identifying address is vital (fail-safe) and to guard against any errors which change the identifying address and which can cause the controller to effectuate operation of the track switch in front of an oncoming train or when the train is over the switch, the address is stored in the EEPROM by encoding the identfying address into unique multi-bit check words.

Abstract: Trains approaching the junction switch for two converging rail lines are detected by separate approach relays which repeat one or more track sections along each approach line. Each approach relay is reset when the train from the corresponding branch, as designated by switch correspondence relays, occupies the switch detector track section. The approach relays control the position of a magnetic stick sequencing relay. The reset of each approach relay by switch section occupancy assures the alternate positioning of the sequencing relay when successive trains simultaneously approach on both branches. The sequencing relay position selects a corresponding interlocking route relay which prepares and initiates the establishment of the route over the junction switch for the next train. Since the sequencing relay alternately operates to each of its positions, the route relays are alternately selected and trains thus alternately move from each approach branch line into the single track.
