Narrative:
While on approach to runway 16L den on localizer and following GS we were told a dash 8 was turning 2 mi in front of us for the runway. We said that we had the airport in sight and we were looking for the aircraft. I then checked the TCASII display to rechk position and closure. We were at 180 KTS and configuring the aircraft to land. I noticed another target on the TCASII that appeared to be much closer and to our right. We got a traffic alert shortly followed by an RA to 'descend now.' we followed the RA and reported the RA to approach at den. We then idented the aircraft, it was an airbus that had overshot runway 16R and was correcting back. It was so close that I could see the pilot looking across the cockpit behind the copilot out the side window. They were entering a hard right turn to go back to the centerline about 100 ft above and 300 ft to our right side. We were not informed of any paralleling traffic by approach control.

Title: NMAC ON 8 MI FINAL AT 8600 FT MSL TO RWY 16L BTWN A B757-200 AND AN AIRBUS ON AN OVERSHOOT ON RWY 16R AT DEN.
Narrative: WHILE ON APCH TO RWY 16L DEN ON LOC AND FOLLOWING GS WE WERE TOLD A DASH 8 WAS TURNING 2 MI IN FRONT OF US FOR THE RWY. WE SAID THAT WE HAD THE ARPT IN SIGHT AND WE WERE LOOKING FOR THE ACFT. I THEN CHKED THE TCASII DISPLAY TO RECHK POS AND CLOSURE. WE WERE AT 180 KTS AND CONFIGURING THE ACFT TO LAND. I NOTICED ANOTHER TARGET ON THE TCASII THAT APPEARED TO BE MUCH CLOSER AND TO OUR R. WE GOT A TFC ALERT SHORTLY FOLLOWED BY AN RA TO 'DSND NOW.' WE FOLLOWED THE RA AND RPTED THE RA TO APCH AT DEN. WE THEN IDENTED THE ACFT, IT WAS AN AIRBUS THAT HAD OVERSHOT RWY 16R AND WAS CORRECTING BACK. IT WAS SO CLOSE THAT I COULD SEE THE PLT LOOKING ACROSS THE COCKPIT BEHIND THE COPLT OUT THE SIDE WINDOW. THEY WERE ENTERING A HARD R TURN TO GO BACK TO THE CTRLINE ABOUT 100 FT ABOVE AND 300 FT TO OUR R SIDE. WE WERE NOT INFORMED OF ANY PARALLELING TFC BY APCH CTL.
