Narrative:

I was involved in a loss of separation between a B727 and a B737. The faster succeeding departure was turned inside the slower preceding departure by the tower controller. I believe the problem herein lies in the receipt of the flight information that the tower controller issued was not passed on to me in a timely manner. We have an antiquated drop tube system that xfers a flight progress strip between the tower and the radar controller. We have 1 box for 2 departure controllers that receive departure strips. The second strip was not in my possession in a timely manner to allow me to recognize a situation that was a potential conflict. Separate drop tubes for each departure controller or electronic xfer of flight information would have most likely assisted me in recognizing what the appropriate action to be taken should have been.

Title: CTLR HAD A LOSS OF SEPARATION ON A B727 AND A B737 ACFT DEPARTING IND.

Narrative: I WAS INVOLVED IN A LOSS OF SEPARATION BTWN A B727 AND A B737. THE FASTER SUCCEEDING DEP WAS TURNED INSIDE THE SLOWER PRECEDING DEP BY THE TWR CTLR. I BELIEVE THE PROB HEREIN LIES IN THE RECEIPT OF THE FLT INFO THAT THE TWR CTLR ISSUED WAS NOT PASSED ON TO ME IN A TIMELY MANNER. WE HAVE AN ANTIQUATED DROP TUBE SYS THAT XFERS A FLT PROGRESS STRIP BTWN THE TWR AND THE RADAR CTLR. WE HAVE 1 BOX FOR 2 DEP CTLRS THAT RECEIVE DEP STRIPS. THE SECOND STRIP WAS NOT IN MY POSSESSION IN A TIMELY MANNER TO ALLOW ME TO RECOGNIZE A SIT THAT WAS A POTENTIAL CONFLICT. SEPARATE DROP TUBES FOR EACH DEP CTLR OR ELECTRONIC XFER OF FLT INFO WOULD HAVE MOST LIKELY ASSISTED ME IN RECOGNIZING WHAT THE APPROPRIATE ACTION TO BE TAKEN SHOULD HAVE BEEN.
