Abstract: There is provided a method of adjusting a height of a car floor plane of a railroad car relative to a platform of a train station. The method includes, using a height adjusting system mounted to an exterior side of the railroad car adjacent the car floor plane, emitting a first ultrasonic beam towards the platform of the train station and monitoring a reflection of the first ultrasonic beam; and generating a first signal based on said monitoring the reflection of the first ultrasonic beam. The method includes, using a processor, operating an actuator of a suspension system of the railroad car to adjust the height of the car floor plane to a height of the platform of the train station based on the generated first signal.
