The Garrett Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. states of Ohio and Indiana. The line runs from Deshler, Ohio, west to Willow Creek, Indiana (in Portage), along a former Baltimore and Ohio Railroad (B&O) line. At its east end, just east of Deshler, the Garrett Subdivision becomes the Willard Subdivision. The line crosses the Toledo Subdivision at Deshler and ends at the junction with the Porter Subdivision and Barr Subdivision at Willow Creek.
