I&O Oasis Subdivision

The Oasis sub-division was the first railroad into Cincinnati.   Constructed by the Little Miami Railroad prior to the Civil War, it became the Pennsylvania Railroads primary route into Cincinnati after the PRR purchased the Little Miami.  The railroad east of Mariemont was abandoned in 1976 by Penn Central (never included in Conrail) and PRR facilities on the line closed in favor of New York Central facilities at Sharonville.  Conrail operated the balance of the line until I&O purchased it in 1995.  The portion from Oakley to Mill was built by the Cincinnati & Chicago Railroad.  The line sees only local traffic from Valley to Oasis, however, from Valley to Mill, Norfolk Southern has trackage rights.  NS dispatches the line between Valley and Mill, as they operate the mot trains, although the line is owned by I&O.  I&O dispatches the line from Valley to Oasis (where the L&N's Ohio River bridge connected with the PRR).
