The data set covers the 48 contiguous States plus the District of Columbia. Purpose: The database provides location and partial attribute information for use in national and regional network analysis applications.

A partial quality control evaluation of the accuracy of these attributes was performed on the database. The likelihood of attribute errors is greater in the urban than in the rural areas. The railroad ownership and trackage rights attributes are not complete. Of the 174,428 line segments in the dataset only 61,183 (approximately 35 percent) contain a value for the first railroad owner. Of 174,428 line segments, only 23,896 (less than 14 percent) contain a value for the first trackage right. For each ASCII attribute file a corresponding dBase format attribute file is supplied. Due to the requirement for the file name extension 'dbf', the attribute file number is included in the file name prefix (RAIL100K.TL2 contains the same attributes RAIL1TL2.DBF). Logical Consistency Report: The database is interconnected and is a flowable network. However, there probably are occasions where the connection between links are not exactly in the correct geographical location. There should be no redundancy of lines or nodes in the database. Initial QC checks found no obvious under- or overshoots. The database, however, is geographically accurate, at the 1:100,000 scale Completeness Report: The only attribute data included in this initial version of the 1:100,000 scale network are track ownership and trackage rights (for 14 railroads) and the State FIPS Code for the links. There are no attributes listed for Sidings. The ownership/trackage attributes were generated by conflating the FRA's 1:2,000,000 and the 1:100,000 TIGER/Line databases to the enhanced 1:100,000 DLG database. The railroad ownership and trackage rights attributes are not complete. Of the 174,428 line segments in the dataset only 61,183 (approximately 35 percent) contain a value for the first railroad owner. Of 174,428 line segments, only 23,896 (less than 14 percent) contain a value for the first trackage right. This version of the dataset contains no node attributes. The sequence number (SEQ) in the ownership (RAIL100K.TL1, RAIL1TL1.DBF) and trackage rights (RAIL100K.TL2, RAIL1TL2.DBF) attribute files may not truly reflect the number of railroads having ownership or trackage rights. In some cases the data provider skipped sequence number(s). For example, LINKID = 2010 has only a single Trackage Right assigned at SEQ eight. Positional Accuracy Horizontal Positional Accuracy Horizontal Positional Accuracy Report: The horizontal accuracy for these data can be stated as being that associated with a 1;100,000 scale map.
