G4 CREW RECEIVED CONFUSING TAXI INSTRUCTIONS FROM TEB GND CTL.

Narrative

THE PROB AROSE DURING PEAK ARR/DEP TIME AT TEB WHEN THE TWR WAS NOTIFIED THAT EWR WAS SWITCHING RWYS; PROMPTING TEB TO SWITCH FROM A S TO N OP DURING THIS PEAK PERIOD. GND AND TWR WERE EXTREMELY OCCUPIED TRYING THEIR BEST TO 'SWAP' THE ARPT. OUR ACFT WAS HOLDING SHORT OF RWY 19 WHEN GND CTL INFORMED US TO TAXI ON TO AND HOLD SHORT OF RWY 24 AWAITING ARRIVING TFC ON RWY 24. WE COMPLIED WITH THIS AND NOTICED THE GND CTLR WAS 'RATTLING OFF' TAXI INSTRUCTIONS NEARLY NON-STOP; WHEN HE INSTRUCTED US TO TURN R ON RWY 24; L ON TXWY L AND HOLD SHORT OF TXWY G; BUT BEFORE WE COULD TURN ONTO RWY 24 HE TOLD US TO CONTINUE STRAIGHT AHEAD ON RWY 19 AND HOLD SHORT TXWY G. THE OTHER PLT AND I NOTICED TFC ON A R BASE TO RWY 1 (WHICH WE WERE NOW ON). I TOLD THE GND CTLR AND HE SAID THE TFC WAS GOING AROUND. AT THIS TIME HE INFORMED US THAT WE SHOULD HAVE TAXIED ONTO RWY 24; L ON TXWY L AND HOLD SHORT OF TXWY G. THIS SURPRISED US SINCE WE BOTH UNDERSTOOD WE WERE TO CONTINUE AHEAD ON RWY 19 TO TXWY G. WE EXPLAINED OUR CASE TO THE CTLR AND HE SAID NOT TO WORRY ABOUT IT. HOWEVER; ONCE WE WERE ESTABLISHED IN CRUISE I CONTACTED THE TEB TWR SUPVR ON THE AIR/GND LINE TO REQUEST THE TAPES. SHE ADVISED ME THAT THE RWY SWAP HAPPENED AT A VERY BUSY TIME AND CREATED HIGH WORKLOADS FOR PLTS/CTLRS. SHE FURTHER STATED THAT NO LEGAL ACTION WAS REQUIRED. EWR COULD HAVE PICKED A LESS BUSY TIME TO SWITCH RWYS SINCE THE WIND FAVORED A N OP ALL MORNING LONG. WHY DID THEY WAIT UNTIL THEN. THE GND CTLR WAS EXTREMELY BUSY AND WAS ISSUING TAXI CLRNCS RAPIDLY WHICH CREATED CONFUSION AT TIMES. THERE WAS LITTLE TIME TO CONFIRM HEARBACK/READBACK.
