MLG FAILED TO COMPLY WITH CLRNC SPEED RESTRICTION AND BEGAN OVERTAKING ACFT LGT.

Narrative

OUR CLRNC WAS OAK 3 DEP RBL TRANS AF; CLB TO 23000'; EXPECT 35000' IN 10 MINS; MAINTAIN 250 KTS UNTIL ADVISED DURING THE DEP. NUMEROUS TFC TARGETS WERE CALLED TO OUR ATTN. SOME WE SAW AND SOME WE DID NOT. AT ABOUT 11000' MSL WE WERE HANDED OFF TO OAK CENTER FROM BAY DEP. WE CHKED IN CLBING TO FL230. I WAS ACCELERATING TO 290 KIAS AS SHOWN ON OUR PDC. I THOUGHT BAY DEP GAVE US RESUME NORMAL SPD. AT 13800' MSL OAK CENTER SAID STOP THE CLB AT 14000' AND WE DID SO ABRUPTLY. THEN ZOA ASKED WHAT OUR SPEED WAS AND IF WE WERE SPD RESTR. WE SAID 290 KTS AND NO FURTHER RESTRICTION. I BELIEVE THEY HAD TFC AHEAD ABOUT 5 MI. I NEVER SAW IT. AFTER THE TFC PASSED WE CONTINUED OUR CLB TO CRUISE ALT. I DON'T KNOW FOR SURE WHETHER OR NOT WE DID IN FACT HAVE A CLRNC TO RESUME NORMAL SPD. WE WERE BUSY WITH NORMAL DEP PROCS; TFC SCANNING; RADIOS AND NAV. I'M NEW TO THE MLG SO I WAS ALSO CONCENTRATING ON SMOOTH CTL INPUTS AND PRECISE NAV. I DON'T BELIEVE THERE WAS ANY COMPROMISE OF SAFETY HERE BUT THERE WAS A POTENTIAL FOR A NEAR MISS. ATC AND PLTS MUST BOTH WORK TOGETHER TO MAKE AIR TRAVEL SAFE. I WILL CERTAINLY PAY CLOSER ATTN TO 'RESUME NORMAL SPD' AND I WILL CONTINUE TO LOOK FOR OTHER TFC. NO MATTER WHO MADE THE ERROR TODAY; THE SYS WORKED AND TFC SEP WAS ACCOMPLISHED.
