This disclosure is generally directed to systems and methods for determining a passage status of a train through a railroad crossing. In an example method, a railroad crossing status detector system provided in a vehicle may determine that a train is approaching the railroad crossing. The determination is made by evaluating a first detection signal received from a first train detection apparatus located on one side of the railroad crossing. The railroad crossing status detector system may then evaluate a second detection signal received from a second train detection apparatus located on the other side of the railroad crossing and determine that the train has traveled past the railroad crossing. The system may also evaluate one or both detection signals to determine whether the train is currently located at the railroad crossing or is backing up after traveling at least partway across the railroad crossing.

There are disclosed apparatuses and methods for withdrawal of a bearing from a gate mechanism including a mechanism housing, a carrier assembly, and discrete fasteners. The mechanism housing includes a receiving bore as well as housing fasteners and housing surfaces located about a periphery of the receiving bore and offset from one another. The carrier assembly includes a carrier housing having a carrier support mating with the receiving bore and a carrier bearing supported for rotation within the carrier housing. The carrier housing has flange fasteners aligning with the housing fasteners and the housing surfaces when the carrier housing mates with the receiving bore. The carrier assembly withdraws from the mechanism housing in response to removing the discrete fasteners from a first group of the flange fasteners aligned with the housing fasteners and inserting the discrete fasteners to a second group of the flange fasteners aligned with the housing surfaces.

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.
