Description:
Abstract: The Rail Network is a comprehensive database of the nation's railway
system at the 1:100,000 scale. The data set covers the 48 contiguous States
plus the District of Columbia.
Purpose: The data set provides location and partial attribute information for
use in national and regional network analysis applications.

Data_Quality_Information
Attribute_ccuracy:
Attribute_Accuracy_Report: The railroad ownership field is complete to
approximately mid-2000.
The FRA reports the following fields as complete:
Railroad Ownership
State/County (FIPS5)
State Code
FRA Regions
Link Type (subject to change)
Passenger Flag
Abandoned Flag
Billing Railroads
Railroad Class
The FRA reports the following fields as incomplete:
Signals
Density Code
Military Flag - applied only in some states
Abandonment Year
Also, the FRA reports that as many nodes as possible have been identified
with a name. There are likely more that are not easily identified. Many
nodes in the 1:100,000 scale rail network are 'mapped' to a node in the
1:2,000,000 scale rail network.
Special note concerning trackage rights: In some cases, a 'short
line'railroad may operate on its larger railroad connection(s) as its
billing railroad. For example, the larger railroad(s) treat traffic
originating or terminating on the short line as if it were originating
or terminating its own line; perform the billing, car reporting, and car
tracking; then share the revenue with the short line. These trackage
rights may exist as four, five, or six in the sequence, while one and
two remain empty.
Logical_Consistency_Report: The network is not topologically connected. There
should be no redundancy of lines or nodes in the data set. The data set
is geographically accurate at the 1:100,000 scale
Completeness_Report: See Attribute Accuracy Report (above).
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: The horizontal accuracy for these
data can be stated as being that associated with data compiled at the
1:100,000 scale.
