The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic
information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing
(MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however,
each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation.
The Rails Shapefile includes all features within the MTDB Super Class "Rail Features" distinguished where the MAF/TIGER Feature
Classification Code (MTFCC) for the feature in MTDB tha begin with "R". This includes main lines such as spur lines, rail
yards, mass transit rail lines such as carlines, streetcar track, monorail or other mass transit rail and special purpose
rail lines such as cog rail lines, incline rail lines and trams.

purpose:
In order for others to use the information in the Census MAF/TIGER database in a geographic information system (GIS) or for
other geographic applications, the Census Bureau releases to the public extracts of the database in the form of TIGER/Line
Shapefiles.

may not be suitable for high-precision measurement applications such as engineering problems, property transfers, or other
uses that might require highly accurate measurements of the earth's surface.Coordinates in the TIGER/Line shapefiles have
six implied decimal places, but the positional accuracy of these coordinates is not as great as the six decimal places suggest.

description TIGER/Line Shapefiles are extracted from the Census MAF/TIGER database by nation, state, county, and entity. Census MAF/TIGER
data for all of the aforementioned geographic entities are then distributed among the shapefiles each containing attributes
for line, polygon, or landmark geographic data.

Completeness Commission
ConceptualConsistency
measure Description
There may be some inconsistencies in feature names along features. An anomaly exists with the sporadic occurrence of road
segments comprising a complete chain with different MAF/TIGER Feature Census Class Code (MTFCC) values assigned. This problem
could affect applications that use the MTFCC values for network analysis, routing, or for assigning symbology to a feature
when creating a map. The Census Bureau performed automated tests to ensure logical consistency and limits of shapefiles. Node/geometry
and topology relationships are collected or generated to satisfy topological edit requirements. These requirements include:
(1) Complete chains must begin and end at nodes. (2) Complete chains must connect to each other at nodes. (3) Complete chains
do not extend through nodes. (4) Left and right polygons are defined for each complete chain element and are consistent throughout
the extract process. (5) The chains representing the limits of the files are free of gaps.
