Narrative:

After pushback ground control cleared us to taxi to runway 25R. As we began taxi, my first officer noticed that there had been a change in the single engine procedures with a left turn after departure instead of the usual right turn. I was discussing the procedures with him so to memorize it before we departed. I had been in and out of las just prior to the reopening of runway 25R and I was in a way 'spring-loaded' to taxi straight ahead and go to runway 25L as I had done the last 2 months. We were still discussing the new procedures and I just called for the pre takeoff checklist when ground control (almost simultaneously with my head looking back to the left) said 'XXXX you better stop.' I stopped quickly and smoothly approximately 20 ft from the hold short line for runway 25R (taxi speed approximately 10-12 KTS). At that moment a white dc-9 on rollout crossed in front of us. Ground then asked if they had given us runway 25R or left and I replied runway 25R. I made a left turn down the taxiway to the departure end of runway 25R. Many thanks to the ground controller (who I called later) for keeping his eyes open. Fatigue, complacency (doing what I had previously done for 2 months), end of day, distraction of new procedures and several others almost added to filling out a lot of reports and possibly bent metal. We must maintain proper vigilance (heads up and outside) during the critical phase of taxiing.

Title: CAPT OF MLG WAS STOPPED BY GND CTLR INTERVENTION FROM TRANSGRESSING ACTIVE RWY AND A POSSIBLE COLLISION WITH ANOTHER ACFT ON ROLLOUT.

Narrative: AFTER PUSHBACK GND CTL CLRED US TO TAXI TO RWY 25R. AS WE BEGAN TAXI, MY FO NOTICED THAT THERE HAD BEEN A CHANGE IN THE SINGLE ENG PROCS WITH A L TURN AFTER DEP INSTEAD OF THE USUAL R TURN. I WAS DISCUSSING THE PROCS WITH HIM SO TO MEMORIZE IT BEFORE WE DEPARTED. I HAD BEEN IN AND OUT OF LAS JUST PRIOR TO THE REOPENING OF RWY 25R AND I WAS IN A WAY 'SPRING-LOADED' TO TAXI STRAIGHT AHEAD AND GO TO RWY 25L AS I HAD DONE THE LAST 2 MONTHS. WE WERE STILL DISCUSSING THE NEW PROCS AND I JUST CALLED FOR THE PRE TKOF CHKLIST WHEN GND CTL (ALMOST SIMULTANEOUSLY WITH MY HEAD LOOKING BACK TO THE L) SAID 'XXXX YOU BETTER STOP.' I STOPPED QUICKLY AND SMOOTHLY APPROX 20 FT FROM THE HOLD SHORT LINE FOR RWY 25R (TAXI SPD APPROX 10-12 KTS). AT THAT MOMENT A WHITE DC-9 ON ROLLOUT CROSSED IN FRONT OF US. GND THEN ASKED IF THEY HAD GIVEN US RWY 25R OR L AND I REPLIED RWY 25R. I MADE A L TURN DOWN THE TXWY TO THE DEP END OF RWY 25R. MANY THANKS TO THE GND CTLR (WHO I CALLED LATER) FOR KEEPING HIS EYES OPEN. FATIGUE, COMPLACENCY (DOING WHAT I HAD PREVIOUSLY DONE FOR 2 MONTHS), END OF DAY, DISTR OF NEW PROCS AND SEVERAL OTHERS ALMOST ADDED TO FILLING OUT A LOT OF RPTS AND POSSIBLY BENT METAL. WE MUST MAINTAIN PROPER VIGILANCE (HEADS UP AND OUTSIDE) DURING THE CRITICAL PHASE OF TAXIING.
