Description:
Abstract: The Rail Network is a comprehensive data set of the
nation's railway system at the 1:2,000,000 scale. The data
set covers the 48 contiguous States plus the District of
Columbia.
Purpose: The database provides location and attribute
information for use in national and regional network
analysis applications.

Attribute_Accuracy_Report:
The FRA reports that the following attribute
is incomplete: Main_track
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.
