The Department of Transportation (DOT) Federal Rail Administration (FRA) Railroad Yards contains detailed attributes on railroad yards located throughout the United States. The yard locations and names, along with the current owner, are being updated by Oak Ridge National Laboratory Geographic Information Sciences and Technology Group (ORNL-GIST) as of 2010. Existing yards that were not in the original dataset are being added, yards that have been removed from service have been retained in the dataset and their status noted in the COMMENTS field. The owning railroad is identified by railroad reporting mark. This can be cross-referenced to the complete railroad owner name in the Railroads table. This dataset is an interim deliverable.
