All WTRM-operated lines are owned by the nonprofit Economic Development Rail II Corporation (EDR-II).

As of 2023, Genesee & Wyoming owns 4 miles of the Warren and Trumbull Railroad, and can hold up to 286,000 pounds of supplies.

The Interstate Commerce Commission approved abandonment by CSX in 1993, after which the Mahoning Valley Economic Development Corporation formed EDR-II to buy the ex-Baltimore and Ohio Railroad line,[2] which had been built by the Painesville and Youngstown Railroad in the 1870s;[citation needed] the WTRM began operations in March 1994.

[3] EDR-II subsequently acquired two lines from Conrail in 1996, with operation by the WTRM under trackage rights.

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