A training and crowd gate for urging animals to move through a passageway. The training and crowd gate includes an overhead track which extends along the passageway and a carriage movably suspended from the track. A cross arm is mounted on the carriage and a plurality of flexible electrical conductors hang downwardly from spaced points on the cross arm to form a barrier across the passageway. An audible signal, a conductor charger and a carriage drive unit are carried on the carriage. A control at an operator's station remote from the crowd gate simultaneously energizes the audible signal means and carriage drive unit and further connects the conductor charger to a source of electrical energy. By repeating the movement of the charged barrier in the presence of an audible signal, the animals are trained to associate the audible signal with the movement of the barrier in a charged state and are subsequently move through the passageway ahead of the barrier even without a charge on the conductors.
