Conrail , formally the Consolidated Rail Corporation, was the primary Class I railroad in the Northeastern United States between 1976 and 1999. The trade name Conrail is a portmanteau based on the company's legal name. It continues to do business as an asset management and network services provider in three Shared Assets Areas that were excluded from the division of its operations during its acquisition by CSX Corporation and the Norfolk Southern Railway.
