Narrative:
Established on the deer park 2 arrival en route to bdl. 2 mi south of the madison VOR an aircraft appeared on TCASII 3 mi north of mad VOR and 500 ft below our altitude (11000 ft, 250 KTS). At the time of our observation we were under ZBW control. As we approached mad VOR we were asked to change frequencys over to bdl approach. Upon changeover, but prior to radio contact, we received a TCASII RA and observed previous mentioned aircraft was now 200 ft below us in a climb. We initiated a climb to 11800 ft and observed aircraft was 300 ft below us. After maneuver we returned to 11000 ft and observed other aircraft 6 O'clock to our position and returned to original altitude of 10500 ft, heading ese. Contact with bdl approach was made and bdl observed aircraft in conflict on his radar.

Title: FLC OF MLG ON STAR IS HANDED OFF FROM CTR TO APCH AND RECEIVES A TCASII RA WHILE ATTEMPTING CONTACT WITH APCH.
Narrative: ESTABLISHED ON THE DEER PARK 2 ARR ENRTE TO BDL. 2 MI S OF THE MADISON VOR AN ACFT APPEARED ON TCASII 3 MI N OF MAD VOR AND 500 FT BELOW OUR ALT (11000 FT, 250 KTS). AT THE TIME OF OUR OBSERVATION WE WERE UNDER ZBW CTL. AS WE APCHED MAD VOR WE WERE ASKED TO CHANGE FREQS OVER TO BDL APCH. UPON CHANGEOVER, BUT PRIOR TO RADIO CONTACT, WE RECEIVED A TCASII RA AND OBSERVED PREVIOUS MENTIONED ACFT WAS NOW 200 FT BELOW US IN A CLB. WE INITIATED A CLB TO 11800 FT AND OBSERVED ACFT WAS 300 FT BELOW US. AFTER MANEUVER WE RETURNED TO 11000 FT AND OBSERVED OTHER ACFT 6 O'CLOCK TO OUR POS AND RETURNED TO ORIGINAL ALT OF 10500 FT, HDG ESE. CONTACT WITH BDL APCH WAS MADE AND BDL OBSERVED ACFT IN CONFLICT ON HIS RADAR.
