PHL LCL CTRL ISSUED RWY XING CLRNC AFTER MISINTERPING COORD FROM THE COORD POS CTLR. A TKOF CLRNC WAS CANCELED.

Narrative

WHILE WORKING THE LCL W POS; I WAS REQUIRED TO COORD WITH THE CABIN COORD POS CTLR TO CROSS RWY 9L WITH ACFT THAT JUST LANDED RWY 9R TO GET TO THEIR GATE. I ASKED TO CROSS RWY 9L TWICE. THE CABIN COORDINATOR SAID TO CROSS. I OBSERVED ANOTHER ACFT BEING WORKED BY LCL E POS THAT WAS WAITING TO CROSS RWY 9L AT TXWY E; START TO MOVE ALSO NBND ACROSS RWY 9L. I ISSUED XING INSTRUCTION TO 2 ACFT; 1 AT TXWY W AND 1 AT TXWY T. THE 'LE' CTLR SAW THE ACFT HE HAD CROSSED CLR RWY 9L AND ISSUED TKOF CLRNC TO A B737 ON RWY 9L. THE A320 I HAD CROSSED AT TXWY T WAS JUST MOVING ONTO THE RWY. THE COORD POS CTLR SAW THIS AND ALERTED 'LE' CTLR TO CANCEL THE B737 TKOF; WHICH HE DID. THE COORD POS CTLR POS IS ABOUT 1 MONTH OLD AT PHL WITH NOT ALL COORD POS CTLRS VERY FAMILIAR WITH IT. THE COORD POS CTLR WHO WAS ORDERED BY THE SUPVR TO OPEN THE POS STATED; 'I'M REALLY NOT COMFORTABLE WITH THIS;' AS DID I. HE WAS TOLD TO 'DO IT ANYHOW AND I'LL GET SOMEONE TO GET YOU OUT WHEN I CAN.' THE COORD POS CTLR WAS ACTUALLY GIVING A RWY XING TO THE GND CTLR FOR RWY 35. I HEARD AND SAW WHAT I WAS EXPECTING. THE SUPVR USED POOR JUDGEMENT IN OPENING THE POS ON RWY 9. THE COORD POS CTLR HAS NO FREQ AND IS THEREFORE UNABLE TO DIRECTLY COMMUNICATE WITH THE PLTS.
