Located at Williamson Medical Center Station 12 was formed in the 2012 to address continued annexation by the City of Franklin. Originally District 12 was part of District 14. Over the years the district became smaller and more fractured due to annexation. In order to provide better service to the remaining portion of the district on the east side of Interstate 65 the district was split from District 14. Station 12 houses Engine 12 which is a 2018 Ford F550 built by Rosenbauer.
