Narrative:

We had received climb to 15000 ft from present 10000 ft. Maximum forward airspeed for traffic. We were at 330 KTS. At 11500 ft ATC said 'stop climb at 12000 ft, cleared direct eed VOR.' as we selected direct eed from present position, a turn was needed. On rollout, my course line showed a .2 from centerline. Ie, his scale showed no offset. First officer side negligible, so at most, 2/10 right of course line. We saw crossing traffic level at 12000 ft and TCASII had chimed alert as 'traffic' as he descended to 12000 ft. He passed just inside our 2 1/2 mi range ring and TCASII RA occurred, 'climb, climb.' at 12300 ft, TCASII said 'clear of conflict.' we notified ATC of action. It was close enough to trigger TCASII RA. I think that after maximum forward airspeed request (which we acknowledged and advised of our speed), controller did not adjust spacing for the speed. He was trying to get our company B757 above and ahead of us for ord. He had given us heading vectors prior to 'direct needles.'

Title: A CLBING ACR JET HAS A POTENTIAL CONFLICT WITH A COMPANY B757 THAT WAS STARTING A CLB FROM 12000 FT ON A XING PATH ON FREQ WITH ZLA, CA.

Narrative: WE HAD RECEIVED CLB TO 15000 FT FROM PRESENT 10000 FT. MAX FORWARD AIRSPD FOR TFC. WE WERE AT 330 KTS. AT 11500 FT ATC SAID 'STOP CLB AT 12000 FT, CLRED DIRECT EED VOR.' AS WE SELECTED DIRECT EED FROM PRESENT POS, A TURN WAS NEEDED. ON ROLLOUT, MY COURSE LINE SHOWED A .2 FROM CTRLINE. IE, HIS SCALE SHOWED NO OFFSET. FO SIDE NEGLIGIBLE, SO AT MOST, 2/10 R OF COURSE LINE. WE SAW XING TFC LEVEL AT 12000 FT AND TCASII HAD CHIMED ALERT AS 'TFC' AS HE DSNDED TO 12000 FT. HE PASSED JUST INSIDE OUR 2 1/2 MI RANGE RING AND TCASII RA OCCURRED, 'CLB, CLB.' AT 12300 FT, TCASII SAID 'CLR OF CONFLICT.' WE NOTIFIED ATC OF ACTION. IT WAS CLOSE ENOUGH TO TRIGGER TCASII RA. I THINK THAT AFTER MAX FORWARD AIRSPD REQUEST (WHICH WE ACKNOWLEDGED AND ADVISED OF OUR SPD), CTLR DID NOT ADJUST SPACING FOR THE SPD. HE WAS TRYING TO GET OUR COMPANY B757 ABOVE AND AHEAD OF US FOR ORD. HE HAD GIVEN US HDG VECTORS PRIOR TO 'DIRECT NEEDLES.'
