ITEM ITEM DESCRIPTION
Shape Data attribute inherent to the ESRI shapefile format,
which defines the data as a point, polyline, or polygon.
Version The VERSION is a 2-digit number that will be
incremented for all records in the database
whenever a new release is distributed. In this
release, the value is "02".
Revision The REVISION is a 2-digit number that will be
incremented individually for each record whenever
a change is made to one of the fields, in
this release the value will be no greater than
"00".
Moddate The MODDATE (or modification date) indicates when
each record in the database was last changed. As
changes are made to record, the modification
date is entered in the format 'yyyymmdd'.
Linkid Unique Identification for each line
Fips5 State/County FIPS Code
Country Country marker
A - United States
C - Canada
M - Mexico
Rrowner1 Reporting marks for the railroad owner -
an abandoned link is designated by the
value 'XXXX'. Rule 260 Codes used where available
Rrowner2 Reporting marks for a second or joint
railroad owner. This owner may also be a
previous owner when the ownership changes in the
middle of a year. Rule 260 Codes used where available.
Rrowner3 Reporting marks for a third railroad owner. Rule 260
Tr1 Abbreviation for the first railroad
having trackage rights.
Tr2 Abbreviation for the second railroad having
trackage rights.
Tr3 Abbreviation for the third railroad having
trackage rights.
Tr4 Abbreviation for the fourth railroad having
trackage rights.
Tr5 Abbreviation for the fifth railroad having
trackage rights.
Tr6 Abbreviation for the sixth railroad having
trackage rights.
Tr7 Abbreviation for the seventh railroad having
trackage rights.
Tr8 Abbreviation for the eight railroad having
trackage rights.
Tr9 Abbreviation for the nineth rail
trackage rights.
Subsidrr Reporting mark of the subsidiary railroad Of the
Owning railroad, rule 260 code. At this time,
only the NS shows a subsidiary - SOU
Abdn_rr The reporting mark of the last carrierto
own/operate the line, if known, rule 260 Code.
Orig_rr The mark of the carrier owning the line in the
near post-WWII period, rule 260 Code. If the
current owner or subsidiary road owned line the
mark is not usually repeated.
Abandoned Abandoned Flag
A - Abandoned, once in use
X - abandoned line,probably never used or constructed
Pass Passenger Flag designating type of passenger
service Military Flag designating importance of this line to the
military - in this version, not complete
State State Postal Code
Fra_reg FRA Region Code
Density Density Code - in this dataset, all values = 0, or unknown.
Rr_class Railroad classification code
" " - not applicable, abandoned
0 - not applicable, active
1 - Class I
2 - Class II
3 - Class III
Signals Type of signaling system - in this version blank
CTC - Centralized Traffic Control
ABS - Automated Block Signals
ACS - Automatic Cab Signals
ATS - Automatic Train Stop
ATC - Automatic Train Control
MAN - Manual Block incl. Dark.
TTO - Time table/Train Order
Railroad Identification of the railroad owner as
provided in the original 1:100,000 scale data.
The field may also contain the value "FRA ADDED"
where the link was not contained in the
original data.
Abdyr Year abandoned, if known -incomplete inthis
version.
Descript FGDL added item based on Railroad
USER NOTES:
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 Federal Railway Administration (FHA) 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.
The dataset provides location and attribute information for use in national and
regional cartographic and network analysis applications.
A note concerning data scale:
Scale is an important factor in data usage. Certain scale datasets are not
suitable for some project, analysis, or modelling purposes. Please be sure
you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the county
level. 1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:250000 scale datasets are recommended for projects that are at the
regional or state level or larger.
Vector datasets with no defined scale or accuracy should be considered
suspect. Make sure you are familiar with your data before using it for
projects or analyses. Every effort has been made to supply the user with
data documentation. For additional information, see the References section
and the Data Source Contact section of this documentation. For more
information regarding scale and accuracy, see our web pages at:

DATA LINEAGE SUMMARY:
In 2001, the Geoplan Center downloaded this data in shapefile format from the Bureau of Transportation Statistics website (http://199.79.179.77/gis/ntatlas/natlas.html). When received, the data was in Geographic projection, Datum: NAD83, Spheroid: GRS1980, Units: Decimal degrees. The data was reprojected to FGDL Albers HPGN, the "descript" item was added based on the existing items 'railroad", and lowercase characters within the attribute table were upcased.
