Examples described herein provide a computer-implemented method for thermal lockout for a motor of a gate crossing mechanism. The method includes monitoring a motor current across a sense resistor of the motor. The method further includes determining a present thermal capacity unit (TCU) at a time interval based on the motor current across the sense resistor. The method further includes determining whether the motor is at a thermal limit by comparing the present TCU to an expected TCU. The method further includes responsive to determining that the motor is at the thermal limit, causing initiating a hard fault.

Examples described herein provide a computer-implemented method for predicting a state of a hall sensor for a motor having a plurality of hall sensors associated therewith. The example method includes receiving a previous state of the hall sensor. The example method further includes detecting a current state of the hall sensor. The example method further includes predicting a predicted next state of the hall sensor based on the previous state of the hall sensor, the current state of the hall sensor, and a direction of a shaft of the motor.

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.

A gate retraction device is provided to return a crossing gate arm to a home position. The gate retraction device comprises a frame to hold a gate pivot pin that is configured to provide a bi-directional rotation of the crossing gate arm. The gate retraction device further comprises a main pivot assembly that receives the gate pivot pin on one end so as to enable rotation of the main pivot assembly in a horizontal plane. The main pivot assembly comprises a first side and a second side opposite of the first side and wherein the main pivot assembly further comprises a spring pin extending on the first side and the second side of the main pivot assembly. The gate retraction device further comprises a spring-loaded assembly trapped against the spring pin of the main pivot assembly as the main pivot assembly rotates.
