The Youngstown Belt Railroad (reporting mark YB) is a part of the Ohio Central Railroad System, which was bought by Genesee & Wyoming Inc. in 2008, serving the area northwest of Youngstown, Ohio.

It also leases a short ex-Baltimore and Ohio Railroad segment from CSX Transportation, formerly operated by the W&T.

The company operates in three separate areas near Warren, Niles, and Youngstown, connected by trackage rights over the Norfolk Southern Railway.

[4] Other ex-Erie trackage includes two branches to Leadville (connecting with the Youngstown and Austintown Railroad there) and the U.S. Steel Ohio Works,[5] and the portion of the line at Warren north of the Warren and Trumbull Railroad junction (opened by the Atlantic and Great Western Railroad as part of a main line to Dayton in 1863[4]).

[7] Effective January 1, 1997, the Youngstown Belt Railroad began operating this trackage under lease.
