Narrative:

After landing on runway 25L at lax, we were told to hold short of runway 25R while on the rollout due to departing traffic. As we turned off at taxiway P, I was beginning the after landing flow and when I looked up, it appeared that the captain was going to cross runway 25R. I said 'stop,' but was too late. It appeared that we had crossed the hold short line, but was difficult to tell how far. A B747-400 was on the takeoff roll and was not told to abort. The B747 rolled beyond our taxiway before it was airborne and had plenty of clearance. Also, tower did not say anything to us about crossing the hold short line. The WX at lax was low visibility and raining at the time this occurred. Also, we were in a new B767-300 that has some differences from the rest of the B767 fleet. This was my first time ever to see this airplane, which caused my after landing flow to take longer than normal. If I wasn't distraction by this new airplane, I would have noticed the captain was not going to stop sooner and could have prevented us from crossing the hold short line.

Title: A B767-300 FO RPTED THAT THE CAPT CROSSED THE HOLD SHORT LINE FOR RWY 25R WITHOUT PERMISSION AT LAX.

Narrative: AFTER LNDG ON RWY 25L AT LAX, WE WERE TOLD TO HOLD SHORT OF RWY 25R WHILE ON THE ROLLOUT DUE TO DEPARTING TFC. AS WE TURNED OFF AT TXWY P, I WAS BEGINNING THE AFTER LNDG FLOW AND WHEN I LOOKED UP, IT APPEARED THAT THE CAPT WAS GOING TO CROSS RWY 25R. I SAID 'STOP,' BUT WAS TOO LATE. IT APPEARED THAT WE HAD CROSSED THE HOLD SHORT LINE, BUT WAS DIFFICULT TO TELL HOW FAR. A B747-400 WAS ON THE TKOF ROLL AND WAS NOT TOLD TO ABORT. THE B747 ROLLED BEYOND OUR TXWY BEFORE IT WAS AIRBORNE AND HAD PLENTY OF CLRNC. ALSO, TWR DID NOT SAY ANYTHING TO US ABOUT XING THE HOLD SHORT LINE. THE WX AT LAX WAS LOW VISIBILITY AND RAINING AT THE TIME THIS OCCURRED. ALSO, WE WERE IN A NEW B767-300 THAT HAS SOME DIFFERENCES FROM THE REST OF THE B767 FLEET. THIS WAS MY FIRST TIME EVER TO SEE THIS AIRPLANE, WHICH CAUSED MY AFTER LNDG FLOW TO TAKE LONGER THAN NORMAL. IF I WASN'T DISTR BY THIS NEW AIRPLANE, I WOULD HAVE NOTICED THE CAPT WAS NOT GOING TO STOP SOONER AND COULD HAVE PREVENTED US FROM XING THE HOLD SHORT LINE.
