Method for securing a level crossing, and stationary control device for a train control system
A method for securing a level crossing permits timely securing of the level crossing and is particularly effective and reliable. The method proceeds in such a way that vehicle data are received from a track-bound vehicle approaching the level crossing by a stationary control device of a train control system. The vehicle data include at least the current position and the current speed of the track-bound vehicle. A strike-in point is determined on the basis of the received vehicle data and route data including at least the location of the level crossing. Securing of the level crossing is triggered when the strike-in point is reached. A stationary control device for a train control system and an arrangement having such a stationary control device are also provided.

DIRECTION CONTROL FOR A MOTOR OF A GATE CROSSING MECHANISM
Examples described herein provide a method for direction control of a motor of a gate crossing mechanism. The method includes providing, by a field-effect transducer (FET) driver, a first voltage via a high output to a normally open contact of a first relay and to a normally closed contact of a second relay. The first voltage causes a shaft of the motor to turn in a first direction. The method further includes providing, by the FET driver, a second voltage via a low output to a normally closed contact of the first relay and to a normally open contact of the second relay. The second voltage causes the shaft of the motor to turn in a second direction opposite the first direction.
MODULAR RAILROAD TRACK SIMULATOR
A system for simulating a railroad track. The system comprises one or more modular track simulation units that are smaller than conventional track simulators and are easy to use with and be connected to a device being tested (e.g., grade crossing predictor). Each track simulation unit may have one of a plurality of impedances associated with a corresponding railroad track length. The units are combinable such that the system can simulate multiple, different track lengths. Each unit has a plurality of test points that can be connected to the device under test and/or used to alter conditions of the simulated track.
Railway road crossing warning system with sensing system electrically-decoupled from railroad track
A railway road crossing warning system (10) including a railway road crossing control unit (18) that may be selectively set to a primary or a secondary mode of operation is provided. In the primary mode of operation, the railway road crossing control unit is responsive to a primary activation signal (21) received from a primary activation-signal source (22), such as a positive train control (PTC) system. In the event the primary activation signal from the primary activation-signal source is not available, railway road crossing control unit (18) is set to the secondary mode of operation, where the railway road crossing control unit is responsive to one or more signals (25) received from a secondary activation-signal source (26) including a railway-vehicle sensing system (28) electrically-decoupled from a railroad track (12). Disclosed embodiments maintain operational robustness in the presence of changing weather and avoid variable electrical ballast conditions that otherwise could develop across the rails, while providing a cost-effective and reliable backup capability for a PTC-started crossing system.
