A crossing gate mechanism includes an electric brushless direct current (BLDC) motor with a sensing device, a crossing gate arm operated via the BLDC motor, a motor brake coupled to the BLDC motor, wherein the motor brake is configured to hold the crossing gate arm in a position, and a controller configured to control the BLDC motor, wherein the controller is configured to control the BLDC motor to raise or lower the crossing gate arm in response to a gate control signal, and wherein, when the motor brake fails to hold the crossing gate arm in the position, the controller is configured to control the BLDC motor to hold the crossing gate arm in the position instead of the motor brake.

Device and method for responding to loss-of-brake on a railroad crossing gate mechanism

A crossing gate mechanism includes an electric motor with one or more sensor(s), a crossing gate arm operated via the electric motor, and a controller configured to control the electric motor to raise or lower the crossing gate arm in response to a gate control signal. The controller is further configured to sense a motion of the crossing gate arm and detect an obstruction that prevents the crossing gate arm to execute the motion. Further, an associated method and non-transitory computer readable medium are described.
