In order to provide increased safety and expedite train movements, three roads operating in Chicago area have completed installation of interlockings, controlled by table interlockers, at two railroad grade crossings within city limits; plants include home and approach signals for protecting and directing train movements, but no switches or derails, operated by interlockings, are involved.
