HB 1676 adds Claiborne, Union, and Grainger counties to the North East Tennessee Railroad Authority, expanding its membership from three to six counties (Anderson, Campbell, Scott, Claiborne, Union, and Grainger). The bill updates the authority's structure to ensure railroad service continuity and economic benefits across all six counties. It revises membership rules, requiring at least four counties to join via a two-thirds vote of their local governing bodies. This change formally extends the authority's jurisdiction to include the three newly added counties.
