Narrative:
Phl has 2 tower frequencys in operation, with 2 aircraft holding short of runway 9L after landing and our flight in position and hold. We were cleared for takeoff. Without our hearing the other 2 aircraft were cleared to cross our runway by another tower frequency. Our tower called for us to stop on runway. As we noticed the aircraft starting to cross, we ended up about 600 ft down runway 9L with brakes set, watching the parade. Bos has the answer. After landing, aircraft are told to hold short of runway, monitor the runway tower frequency. That way aircraft crossing and those told to take off can all hear what is going on.
