Abstract: AUTOMATIC CONTROL SYSTEM FOR RAILROAD INTERLOCKING       ABSTRACT OF THE DISCLOSURE    Trains approaching the junction switch for two converging rail lines are detected by separate approach relays which repeat one or more track sections along each approach line.          Each approach relay is reset when the train from the corres-ponding branch, as designated by switch correspondence relays, occupies the switch detector track section.  The approach relays control the position of a magnetic stick sequencing relay.  The reset of each approach relay by switch section occupancy assures the alternate positioning of the sequencing relay when successive trains simultaneously approach on both branches.  The sequencing relay position selects a correspond-ing interlocking route relay which prepares and initiates the establishment of the route over the junction switch for the next train.  Since the sequencing relay alternately operate to each of its positions, the route relays are alternately selected and trains thus alternately move from each approach branch line into the single track.
