Narrative:

Upon departure from runway 30R at stl, we were assigned an altitude of 5000 ft and a heading of 335 degrees. Shortly after rotation, the first officer pointed out traffic which was departing runway 30L and was below our altitude. Tower control then gave us a heading of 340 degrees and asked us to contact departure. The first officer then contacted departure. Departure assigned us 6000 ft and to maintain 340 degrees. Upon reaching 6000 ft, the departure controller assigned us a new heading. The first officer read back the heading, but I had not heard it because we had received a TA (TCASII) which was associated with a single chime and flashing amber annunciators. I asked the first officer to give me the heading, but he had not written it down. I then asked him to ask departure to repeat the heading. The first officer asked departure to repeat the heading, but departure did not respond. TCASII was showing a target below our altitude and to the left. Shortly thereafter, we received an RA associated with a triple chime and flashing red annunciators. I believed the RA to be associated with the traffic to the left and I began to climb. Almost immediately, departure said we were clear of conflict and I began to level off at 6300 ft. ATC had never advised us of a conflict or to take immediate action. The first officer and I then noticed traffic about 1000 ft above us and to the right which must have been associated with the RA. Departure then said that he showed us at 6300 ft and he asked us to maintain 6000 ft and to turn to 270 degrees. We were given 15000 ft shortly thereafter and the flight continued to lnk normally.

Narrative: UPON DEP FROM RWY 30R AT STL, WE WERE ASSIGNED AN ALT OF 5000 FT AND A HDG OF 335 DEGS. SHORTLY AFTER ROTATION, THE FO POINTED OUT TFC WHICH WAS DEPARTING RWY 30L AND WAS BELOW OUR ALT. TWR CTL THEN GAVE US A HDG OF 340 DEGS AND ASKED US TO CONTACT DEP. THE FO THEN CONTACTED DEP. DEP ASSIGNED US 6000 FT AND TO MAINTAIN 340 DEGS. UPON REACHING 6000 FT, THE DEP CTLR ASSIGNED US A NEW HDG. THE FO READ BACK THE HDG, BUT I HAD NOT HEARD IT BECAUSE WE HAD RECEIVED A TA (TCASII) WHICH WAS ASSOCIATED WITH A SINGLE CHIME AND FLASHING AMBER ANNUNCIATORS. I ASKED THE FO TO GIVE ME THE HDG, BUT HE HAD NOT WRITTEN IT DOWN. I THEN ASKED HIM TO ASK DEP TO REPEAT THE HDG. THE FO ASKED DEP TO REPEAT THE HDG, BUT DEP DID NOT RESPOND. TCASII WAS SHOWING A TARGET BELOW OUR ALT AND TO THE L. SHORTLY THEREAFTER, WE RECEIVED AN RA ASSOCIATED WITH A TRIPLE CHIME AND FLASHING RED ANNUNCIATORS. I BELIEVED THE RA TO BE ASSOCIATED WITH THE TFC TO THE L AND I BEGAN TO CLB. ALMOST IMMEDIATELY, DEP SAID WE WERE CLR OF CONFLICT AND I BEGAN TO LEVEL OFF AT 6300 FT. ATC HAD NEVER ADVISED US OF A CONFLICT OR TO TAKE IMMEDIATE ACTION. THE FO AND I THEN NOTICED TFC ABOUT 1000 FT ABOVE US AND TO THE R WHICH MUST HAVE BEEN ASSOCIATED WITH THE RA. DEP THEN SAID THAT HE SHOWED US AT 6300 FT AND HE ASKED US TO MAINTAIN 6000 FT AND TO TURN TO 270 DEGS. WE WERE GIVEN 15000 FT SHORTLY THEREAFTER AND THE FLT CONTINUED TO LNK NORMALLY.
