The disclosure is directed to a method of detecting an object beneath a train.

The method may also include processing the second signal in accordance with a first procedure if the first signal indicates a speed of the train less than the threshold level, and processing the second signal in accordance with a second procedure different from the first procedure if the first signal is equal to or greater than the threshold level.
