Narrative:
Operating as flight X non passenger repos flight to atl from crw. On approach to atl, approach controller was busy. Last assigned heading was 180 degrees, altitude was 6000 ft MSL. We were being vectored to runway 26R localizer. As we approached the localizer course we commented on being left on the heading. I was the PNF, could not get through to reach ATC. I then noticed traffic on TCASII. I looked up to visually acquire the traffic when we received the 'traffic, traffic' aural message. I instructed the first officer to turn right to join the runway 26R localizer. I saw a B727 at our altitude in a left turn. He disappeared behind my aircraft. ATC then cleared us to join runway 26R, initial heading 290 degrees. Immediately we were given a descent clearance to 5000 ft then 4000 ft. We proceeded in to runway 26R and landed without incident. When being vectored for final in atl, sometimes you are given a heading to pass through the localizer, usually for spacing. If this is going to happen, usually the ATC will tell you about it. I noticed us going through and was unable to query controller. I thought we were being sent through intentionally until I saw the traffic on TCASII. I then decided to turn right to join the runway 26R localizer.

Title: APCH CTLR HAS ACFT VECTORED THROUGH LOC AND CONFLICTS WITH ACR ON PARALLEL RWY. POSSIBLE LTSS.
Narrative: OPERATING AS FLT X NON PAX REPOS FLT TO ATL FROM CRW. ON APCH TO ATL, APCH CTLR WAS BUSY. LAST ASSIGNED HDG WAS 180 DEGS, ALT WAS 6000 FT MSL. WE WERE BEING VECTORED TO RWY 26R LOC. AS WE APCHED THE LOC COURSE WE COMMENTED ON BEING L ON THE HDG. I WAS THE PNF, COULD NOT GET THROUGH TO REACH ATC. I THEN NOTICED TFC ON TCASII. I LOOKED UP TO VISUALLY ACQUIRE THE TFC WHEN WE RECEIVED THE 'TFC, TFC' AURAL MESSAGE. I INSTRUCTED THE FO TO TURN R TO JOIN THE RWY 26R LOC. I SAW A B727 AT OUR ALT IN A L TURN. HE DISAPPEARED BEHIND MY ACFT. ATC THEN CLRED US TO JOIN RWY 26R, INITIAL HDG 290 DEGS. IMMEDIATELY WE WERE GIVEN A DSCNT CLRNC TO 5000 FT THEN 4000 FT. WE PROCEEDED IN TO RWY 26R AND LANDED WITHOUT INCIDENT. WHEN BEING VECTORED FOR FINAL IN ATL, SOMETIMES YOU ARE GIVEN A HDG TO PASS THROUGH THE LOC, USUALLY FOR SPACING. IF THIS IS GOING TO HAPPEN, USUALLY THE ATC WILL TELL YOU ABOUT IT. I NOTICED US GOING THROUGH AND WAS UNABLE TO QUERY CTLR. I THOUGHT WE WERE BEING SENT THROUGH INTENTIONALLY UNTIL I SAW THE TFC ON TCASII. I THEN DECIDED TO TURN R TO JOIN THE RWY 26R LOC.
