In 2002, IRR's "Bangor and Aroostook System" (BAR, CDAC, VBB, and QS/NV) entered bankruptcy protection and service became jeopardized. Both Canadian National and New Brunswick Southern Railway applied to the Surface Transportation Board for permission to operate former BAR lines that served major industrial customers in northern Maine. CN was granted permission to operate from Van Buren, Maine to Madawaska, Maine, while NBSR was granted permission to operate former BAR lines from Brownville Junction south to Searsport and north to Madawaska; neither applications became necessary after the BAR lines were sold.
