摘要： A method of railroad track control includes partitioning a physical track block into a plurality of virtual track blocks, the physical track block defined by first and second insulated joints disposed at corresponding first and second ends of a length of railroad track. The presence of an electrical circuit discontinuity in one of the plurality of virtual track blocks; is detected and in response a corresponding virtual track block position code indicating the presence of the discontinuity in the one of the plurality of virtual track blocks is generated.

摘要： A surge suppression circuit for a track circuit is provided. The surge suppression circuit comprises a first surge protection device including a first pair of silicon avalanche diodes and a second surge protection device including a second pair of silicon avalanche diodes. The first surge protection device is connected on a first connection line between a first terminal of a railroad signaling electronic equipment to be protected from a surge and a first terminal of a first rail of two physical rails. The second surge protection device is connected on a second connection line between a second terminal of the railroad signaling electronic equipment and a second terminal of a second rail of the two physical rails. The first surge protection device and the second surge protection device are connected to an earth ground terminal.

摘要： Systems, devices, media, and methods are presented for controlling remote equipment in a network. A switch heater control system includes a weather modeling function. The system periodically obtains weather data according to a predetermined time interval. Based on the closest weather data set, the weather modeling function generates a hyperlocal forecast associated with each switch heater location. The system includes an active snowfall mode and a maintenance mode that controls heating based on an estimate of local snow depth, adjusted for wind conditions and passing trains. When the hyperlocal forecast indicates heating is required, the system calculates a melt duration, starts a timer, and transmits a start signal to the switch heater.

摘要： A simulated track inductor mount including a base configured to be fixed against a supporting surface and an inductor hub attached to and extending from the base. The inductor hub includes one or more surfaces defining a margin and being configured to engage with an inner surface of the simulated track inductor, and the one or more surfaces are fixed to a camming tab configured to flex to removably seat the simulated track inductor on the inductor hub.

摘要： A system of train control uses a quasi-moving block methodology for controlling operation of a plurality of trains from a remote office. The office parses the route information for each train into non-overlapping movement authorities that are issued via a communications network. As each train proceeds, it communicates with the office to automatically roll up its movement authority and release the portion of the movement authority behind the train. The office then extends the movement authority of the subsequent train to reflect the released portion of the movement authority of the leading train. The track can be divided into a series of track circuits to enable detection of broken rail or unexpected occupancy. The office segment can then control operation of trains accordingly if broken rail or unexpected occupancy is detected in the train's movement authority.

摘要： Method and system for communicating data between a transmitter and a receiver via a physical transmission medium interposed there between, wherein the transmitter outputs over the transmission medium towards the receiver, a predefined precursor signal followed by a target signal carrying data packet. Based on the precursor signal received at the receiver, estimated values of actual electrical parameters of the physical transmission medium are computed via a predetermined model of the physical transmission medium, wherein the computed estimated values of the electrical parameters are indicative of a distortion caused by the physical transmission medium on the predefined precursor signal outputted by the transmitter. The data packets originally outputted by the transmitter are estimated based on the computed estimated values of the actual electrical parameters and on the target signal received at the receiver.

摘要： Systems and methods for providing wireless communication between the interior of a moving vehicle (10, C1, C2) and stationary communication systems (11-1A, 11-2A) located along a track of the vehicle (10, C1, C2) are described, with the vehicle (10) having antenna sets (A1, A2) each including a plurality of antennas (A11, A12, A21, A22) mounted onto the vehicle (10) wherein said plurality of antennas has at least two pairs of antennas orthogonal polarization with respect to each other and wherein within each pair the antennas are configured to have full pattern diversity with a first antenna (A11, A21) of each pair oriented to receive/transmit signals essentially in direction of travel and a second antenna (A12, A22) of each pair oriented to receive/transmit signals essentially in direction opposite to the direction of travel and the stationary communication system (11-1, 11-2) comprising antenna systems (11-1A, 11-2A) for providing during operation two cross-polarized RF antenna corridors (17-1, 17-2) in the opposite directions along the track (19) and wherein the RF antenna corridors (17-1, 17-2) overlap along a section of the track, aid receiving/transmitting two independent signal channels (s5, s6) over the first cross-polarized RF antenna corridor (17-1) and receiving/transmitting two further independent signal channels (s7, s8) over the second cross-polarized RF antenna corridor (17-2).
