A herringbone-type milking parlor of the type in which the cow is milked from the side utilizes a rotating rail that moves from a horizontal exit position to a vertical position to urge the cow to exit from the milking stall. The rail stays in this position until a new cow has moved into the milking stall, at which time the rail indexes back to a position short of vertical to engage the brisket of the cow and move it gently back towards the rump rail and into a proper milking position.
