ACFT X (B757) WHILE TAXIING; ACFT Y (A320) CROSSED IN FRONT OF THEM. RPTR CONTENDS THAT THE GND CTLR NEVER GAVE THEM ANY INFO ON THE XING TAXIING TFC.

Narrative

GND CTL CONFUSION DURING TAXIING TO RWY 4L AT EWR FROM TERMINAL. SCENARIO AS FOLLOWS: HOLDING SHORT AT TXWY BM; GND CTL INSTRUCTIONS WERE; AFTER PASSING B737 (L TO R); FOLLOW COMPANY B737 TO RWY 4L. AT THE NEXT INTXN; WE WERE INSTRUCTED TO HOLD SHORT FOR A COMPANY RJ PASSING L TO R AND CONTINUE TO RWY 4L FOLLOWING THE SAME B737. AFTER FOLLOWING GND CTL INSTRUCTIONS; I CONTINUED TO TAXI AS INSTRUCTED WHEN AN A320 CROSSED IN FRONT OF US WITH NO CALL FROM GND CTL. HAD I NOT STOPPED; I FEEL WE WOULD HAVE COLLIDED. I CONTINUED TO TAXI AND THE NEXT INSTRUCTION FROM GND WAS HOLD SHORT AT TXWY V AND GIVE WAY TO AN ATR AND SWITCH TO TWR. THE PROB WAS I HAD ALREADY PASSED TXWY V AND THE ATR. AFTER SWITCHING TO TWR; I SWITCHED BACK TO GND AND STATED WHAT HAD HAPPENED. A DIFFERENT CTLR CAME ON FREQ AND INSTRUCTED ME TO HOLD SHORT AND WAIT FOR THE ATR AND SWITCH TO TWR. TWR INSTRUCTED ME TO POS AND HOLD WITH NO FURTHER REF TO THE ATR. I TOOK OFF WITH NO FURTHER INCIDENT. EWR GND CTL IS ALWAYS VERY BUSY AND CAN BE VERY DEMANDING -- EVEN TO THE MOST EXPERIENCED CTLRS. I THINK THE CAUSE OF THE ABOVE STATED PROB WAS A RELATIVELY INEXPERIENCED GND CTLR THAT GOT A LITTLE BIT BEHIND.
