The Robbinsville Industrial Track is a short freight line in Mercer County, New Jersey. The line is part of CSAO (Conrail Shared Assets Operations). The line is serviced by train WPBU-20, which is based out of Conrail's Burlington Yard in Burlington, NJ. At the beginning of 2010, Conrail was granted $2 million in funds from the NJ Department of Transportation to complete major upgrades to the line.[1]
