Narrative:
Location: 5 mi southeast of love field. Had been using GPS coupled to #1 DFGS to navigation on the arrival into dfw. Approach vectored us off and told us to intercept the runway 31R localizer and expect the stadium visual. We had not expected this since the ATIS said we could expect runway 35R. The first officer was new and had never flown into dfw this way before. As we scrambled to get out the plates, the first officer dialed in the localizer frequency and course (he was the PF) and armed the localizer. I dialed in TTT to identify one of the points on the visual. While we briefed, the aircraft flew through the course because we still had the aircraft on DFGS #1. The controller caught the error and there did not seem to be any conflicts. We could have prevented this by noticing that the flight mode annunciator showed VOR, not localizer, and remembered to switch the DFGS to #2. Supplemental information from acn 434592: during first officer IOE, first officer was PF using GPS with DFGS #1 selected for instructional purposes.

Title: AN S80 FLIES THROUGH THE LOC COURSE ON A NEW RWY ASSIGNMENT WHILE THE MCP WAS SET FOR THE WRONG GUIDANCE SYS.
Narrative: LOCATION: 5 MI SE OF LOVE FIELD. HAD BEEN USING GPS COUPLED TO #1 DFGS TO NAV ON THE ARR INTO DFW. APCH VECTORED US OFF AND TOLD US TO INTERCEPT THE RWY 31R LOC AND EXPECT THE STADIUM VISUAL. WE HAD NOT EXPECTED THIS SINCE THE ATIS SAID WE COULD EXPECT RWY 35R. THE FO WAS NEW AND HAD NEVER FLOWN INTO DFW THIS WAY BEFORE. AS WE SCRAMBLED TO GET OUT THE PLATES, THE FO DIALED IN THE LOC FREQ AND COURSE (HE WAS THE PF) AND ARMED THE LOC. I DIALED IN TTT TO IDENT ONE OF THE POINTS ON THE VISUAL. WHILE WE BRIEFED, THE ACFT FLEW THROUGH THE COURSE BECAUSE WE STILL HAD THE ACFT ON DFGS #1. THE CTLR CAUGHT THE ERROR AND THERE DID NOT SEEM TO BE ANY CONFLICTS. WE COULD HAVE PREVENTED THIS BY NOTICING THAT THE FLT MODE ANNUNCIATOR SHOWED VOR, NOT LOC, AND REMEMBERED TO SWITCH THE DFGS TO #2. SUPPLEMENTAL INFO FROM ACN 434592: DURING FO IOE, FO WAS PF USING GPS WITH DFGS #1 SELECTED FOR INSTRUCTIONAL PURPOSES.
