Figure 2-31: U.S. DOT-FRA Crossing Inventory Form Part I, Item 25
Leave this field blank because FRA will populate this field with information from Notices
of Quiet Zone Establishment that have been received. This item will indicate whether a
quiet zone is in effect for the crossing. If a quiet zone is in effect, this item will indicate if
it is for 24 hours per day or only a partial day (usually 10 p.m. to 7 a.m.)
If the crossing is not located in a Quiet Zone, the “No” box will be checked. If it is
located in a 24-hour quiet zone, the “24 hr” box will be checked. If it is located in a
partial quiet zone, the “Partial” box will be checked. If it is in a Chicago-excused area
(those crossings in the Chicago area that are currently excused from the Train Horn
Rule), the “Chicago Excused” box will be checked. The effective date that was provided
in the Notice of Establishment will be the “Date Established.” (Note: “Chicago Excused”
crossings will not have an entry in the “Date Established”).
26. HSR Corridor ID
Figure 2-32: U.S. DOT-FRA Crossing Inventory Form Part I, Item 26
If this is a high-speed rail (HSR) crossing, enter the four-character “HSR Corridor ID” as
defined in Appendix F to this manual.
Note: This field is used to identify the “Section 1010” or “Section 1103” HSR corridor on
which the crossing is located. If the crossing is located on such a corridor, enter the
“HSR Corridor ID,” a four character code (ABC#) as defined in Appendix F to this
manual. The corridor may be divided into logical sections by including a numeric
number (1–9) for the “#” character. If a numeric number is not used, replace “#” with “X.”
FRA will assign an HSR Corridor ID for any corridor, or portion thereof that is not
currently defined in the Appendix. If “HSR Corridor ID” is not applicable, then check the
N/A box.
27. Latitude

Highway-Rail Crossing Inventory Instruction and Procedures Manual

Instructions for Completing the U.S. DOT Crossing Inventory Form
Enter the latitudinal coordinate as measured at the center of the crossing. This field,
along with “Longitude,” is used to identify the crossing location using a standardized
Global Positioning System (GPS) location point. The “Latitude” must be entered in
decimal form as (nn.nnnnnnn), with at least five digits to the right of the decimal point
(which is accurate to 4 feet). We will accept up to seven places to the right of the
decimal point.
Actual latitude measurements can be obtained either with a GPS device at the crossing
location or by using an Internet mapping program, such as Google Maps or Bing Maps.
To find latitude and longitude on Google Maps, zoom in on the location of the crossing,
right click on the crossing, and select “What’s Here?” The coordinates will appear in the
search bar above the map, with the latitude measurement listed first. In Bing Maps,
right click on the crossing and select the gray box that either says “location” or identifies
the closest street address. The coordinates will appear under the address to the left of
the map, with the latitude listed first.
To convert latitude values from degrees, minutes, and seconds to decimal form:
Latitude in decimal format = degrees + (minutes divided by 60) + (seconds divided by
3,600).
Latitude coordinate ranges within the continental United States are from 24 to 49
degrees. Alaska latitude values range from 50 to 71 degrees.
Note: The FRA Office of Railroad Safety uses the World Geodetic System 1984
(WGS-84) datum standard. (A datum is the measurement [shape] of the earth's
ellipsoid.)
28. Longitude
Figure 2-34: U.S. DOT-FRA Crossing Inventory Form Part I, Item 28
Enter the longitudinal coordinate as measured at the center of the crossing. This field,
along with “Latitude,” is used to identify the crossing location using a standardized GPS
location point. The “Longitude” must be entered in decimal form as (-nnn.nnnnnnn),
with at least five digits to the right of the decimal point (which is accurate to 4 feet).
FRA will accept up to seven places to the right of the decimal point.
Actual longitude measurements can be obtained either with a GPS device at the
crossing location, or by using an Internet mapping program, such as Google Maps or
Bing Maps. To find latitude and longitude on Google Maps, zoom in on the location of
the crossing, right click on the crossing and select “What’s Here?” The coordinates will
appear in the search bar above the map, with the longitude measurement listed second.
In Bing Maps, right click on the crossing and select the gray box that either says

“location” or identifies the closest street address. The coordinates will appear under the
address to the left of the map, with the longitude listed second.
To convert longitude values from degrees, minutes, and seconds to decimal form:
Longitude in decimal format = degrees + (minutes divided by 60) + (seconds divided by
3,600).
Longitude coordinate ranges within the continental United States are from -66 to -124
degrees. Alaska longitude values range from -165 to -132 degrees.
Note: The FRA Office of Railroad Safety uses the WGS-84 datum standard.
29. Lat/Long Source
Figure 2-35: U.S. DOT-FRA Crossing Inventory Form Part I, Item 29
Enter a check in the appropriate box to indicate the source, “Actual” or “Estimated,” for
the latitude and longitude coordinate values being provided.
Actual values are those where GPS measurements are taken at the crossing or
determined by a positive identification method. Latitude and longitude values, in
general, should be taken in the field at the intersection of the centerline of the roadway
or pathway with the centerline of the railroad tracks with a horizontal accuracy of
1 meter or better. Mapping software, such as Google or Bing maps, may be used to
obtain “Actual” values.
Otherwise, the values are indicated as “Estimated.” Any values provided after March 7,
2015 must be actual values.
30. Railroad Use
Figure 2-36: U.S. DOT-FRA Crossing Inventory Form Part I, Item 30
Only the railroad may enter any text or data of its choice in these fields. For example,
the railroad may note whether monitoring is being conducted at a passive crossing. No
editing will be performed on these fields. These fields are optional.
