摘要： A system and method for detecting the presence or absence of cars, locomotives, or obstructions which may occupy a particular section of track of a model railroad. Digital Command Control signals are used to provide the excitation voltage needed to perform a measurement of the capacitance of an unoccupied section of track. Deviations from this unoccupied capacitance are then measured to indicate occupancy.

摘要： An electronic code transmitter is disclosed for driving a number of code following relays of a railroad signaling system. The electronic code transmitter comprises a timing circuit and a driving circuit. The timing circuit generates, at a predetermined code rate, square wave pulses with an approximate 50/50 duty cycle. The driving circuit receives the square wave pulses and conducts, at the predetermined code rate, a power source to the code following relays. Where the timing circuit is a timer IC operating in an astable oscillator mode, the timer IC receives an isolated DC power from a DC-DC converter. A resistor is coupled in parallel with the code following relays if the code following relays present a sufficiently high impedance load to the electronic code transmitter. Thereby, the electronic code transmitter is capable to drive code following relays of any load impedance.

摘要： A solid state code following track relay receives pulsating rail current from a railway code transmitter. The track relay includes first and second inputs structured to receive the rail current. Two Hall effect digital current sensors each have a coil and an output, which responds to current flowing through the coil. The coils of the current sensors are electrically connected in series between the first and second inputs and are structured to receive the rail current. The outputs of the current sensors are structured to turn on and off in response to the rail current. A circuit including dual one-shot multivibrators, which are triggered by positive and negative going edges from the respective current sensors, and a flip-flop, which is set and reset by the outputs of the respective multivibrators, determines that each of the current sensors is functional. Two solid state outputs are structured to follow the rail current.

摘要： A railway vehicle safety shunt system includes a pair of axle-mounted rail wheels having outer circumferential surfaces that engage the upper surfaces of the rails, respectively, radially outwardly flange portions that engage the lateral portions of the rails, respectively, and adjacent end surfaces that are respectively engaged by a pair of spring-biased wire brushes arranged parallel with the axis of rotation of the associated rail wheel. The brushes are electrically connected by a shunt conductor, thereby to present an indication of the location of the railway vehicle at a remote vehicle position monitoring and dispatching station.
