Very little of Marion Yard still exists, CSX does some switching there.
The route itself is out of service or pulled up long ago over much of the mileage west of Youngstown, Ohio.
In Ohio Ravenna to Kent and the Barberton to Rittman segments are operated by the Akron Barberton Cluster Railroad.
From West Salem to Mansfield it is operated by the Ashland Railway.
From Galion to Marion it is operated by CSX, it was the Erie/NYC joint double track.
West of Marion, nothing. The Dayton Branch is also history.
On the Cleveland line between Solon and E55th St in Cleveland are operated by another shortline, it's changed hands a couple times and I don't know who owns it. East of Solon and west of E. 55th St, it's all gone.
That's just about it for Ohio.
