paragraph (h)(5) and revised to require that electronic storage of
records be initiated by the person making the inspection within 72
hours following completion of the inspection. Existing paragraph (e)(2)
requires that electronic storage be initiated within 24 hours of
completion of the inspection. FRA believes that giving track owners an
additional 48 hours to upload inspection records would provide needed
flexibility without negatively impacting safety. For example, where an
inspector does not have internet connection or experiences computer
failure, it may take more than 24 hours to upload the inspection
report. The new 72-hour requirement would also take into account the
possibility of technical issues occurring late on a Friday that cannot
be remedied until the following Monday, due to limited availability of
technical support personnel.
    FRA proposes removing existing paragraph (e)(5), which requires
that the electronic system provide for maintenance of the inspection
records without corruption or loss of data. FRA believes that proposed
paragraph (h)(2), which would require that the track owner monitor the
database to ensure record accuracy, would make existing paragraph
(e)(5) redundant. FRA also proposes removing existing paragraph (e)(6),
which generally requires that track owners make paper copies of
electronic records available to FRA. FRA believes that this would also
be redundant given that existing paragraph (d) already requires this,
and would continue to require as redesignated paragraph (g). Finally,
FRA proposes removing existing paragraph (e)(7), which requires that
electronic track inspection records be kept available to persons who
performed the inspections and to persons performing subsequent
inspections. FRA believes this would be made redundant with the
addition of proposed paragraph (f), which would require the same for
all records.
    FRA is redesignating paragraph (f) as paragraph (i) and slightly
revising it for punctuation; no substantive change is intended.

VI. Regulatory Impact and Notices

A. Executive Order 12866, and DOT Regulatory Policies and Procedures

    This proposed rule is a significant regulatory action within the
meaning of Executive Order 12866 (E.O. 12866) and DOT policies and
procedures. See DOT Order 2100.6, Policies and Procedures for
Rulemaking (Dec. 20, 2018), available at https://cms.dot.gov/sites/dot.gov/files/docs/regulations/328561/dot-order-21006-rulemaking-process-signed-122018.pdf. Additionally, this proposed rule is
considered an E.O. 13771 deregulatory action. Details on the estimated
cost savings of this proposed rule can be found in the proposed rule's
Regulatory Impact Analysis, which FRA has prepared and placed in the
docket (docket number FRA-2018-0104). The analysis details estimated
costs and cost savings the railroad track owners regulated by the rule
are likely to see over a 10-year period.
    FRA proposes to revise its regulations governing the minimum safety
requirements for railroad track. The proposed changes include:
Permitting the inspection of rail using continuous rail testing;
allowing the use of flange-bearing frogs in crossing diamonds; relaxing
the guard check gage limits on heavy-point frogs used in Class 5 track;
removing the high-density commuter line exception; and other
miscellaneous revisions.
    The proposed revisions would benefit railroad track owners and the
public by reducing unnecessary costs and incentivizing innovation,
while not negatively affecting safety.
    The following table shows the net cost savings of this proposed
rule, over the 10-year analysis.

                                          Net Cost Savings, in Millions

----------------------------------------------------------------------------------------------------------------

    The estimated 10-year net cost savings of the proposed rule would
be $122.8 million (7%) and $148.9 million (3%). The annualized net cost
savings would be $17.5 million (7%) and $17.4 million (3%).
    The additional flexibility of this proposed rule would result in
cost savings for railroad track owners. Continuous rail testing would
reduce overtime hours for maintenance-of-way employees. The flange-
bearing frog

changes would eliminate the required inspection time during the first
week when compared to current conditions under the FRA waiver. The
continuous testing, flange-bearing frog, and heavy-point frog changes
would eliminate the need for and costs of applying for waivers to
implement such a testing practice and track components. In fact, fewer
slow orders would be needed with continuous testing, which would result
in a significant cost savings.
    The table below presents the estimated cost savings associated with
the proposed rule, over the 10-year analysis.

----------------------------------------------------------------------------------------------------------------

    The estimated 10-year total cost savings of the proposed rule would
be $148.7 million (discounted at 7%) and $180.3 million (discounted at
3%). The annualized cost savings would be $21.2 million (7%) and $21.1
million (3%).
    If railroad track owners choose to take advantage of the cost
savings from this proposed rule, they would incur additional labor
costs associated with continuous rail testing. These costs are
voluntary because track owners would only incur them if they choose to
operate continuous rail testing vehicles. The table below presents the
estimated costs, over the 10-year analysis.

----------------------------------------------------------------------------------------------------------------

    The estimated 10-year costs of the proposed rule would be $25.9
million (discounted at 7%) and $31.4 million (discounted at 3%). The
annualized costs would be $3.7 million (at both 7% and 3%).
    The proposed rule would also encourage the use of continuous rail
testing, which may reduce certain types of derailments. FRA does not
have sufficient data to estimate the reduction in derailments. However,
FRA expects the proposed rule to result in safety benefits from fewer
injuries, fatalities, and property and track damage.

B. Regulatory Flexibility Act

    The Regulatory Flexibility Act of 1980 (5 U.S.C. 601 et seq.) and
Executive Order 13272 (67 FR 53461, Aug. 16, 2002) require agency
review of proposed and final rules to assess their impacts on small
entities. An agency must prepare an Initial Regulatory Flexibility
Analysis (IRFA) unless it determines and certifies that a rule, if
promulgated, would not have a significant economic impact on a
substantial number of small entities. FRA has not determined whether
this proposed rule would have a significant economic impact on a
substantial number of small entities.
    Therefore, FRA prepared an IRFA which is included as an appendix to
the accompanying Regulatory Impact Analysis and available in the docket
for this rulemaking (FRA 2018-0104) to aid the public in commenting on
the potential small business impacts of the requirements in this NPRM.

C. Paperwork Reduction Act

    The information collection requirements in this proposed rule are
being submitted for approval to the Office of Management and Budget
(OMB) under the Paperwork Reduction Act of 1995, 44 U.S.C. 3501 et seq.
The sections that contain the current and new information collection
requirements and the estimated time to fulfill each requirement are as
follows:

    All estimates include the time for reviewing instructions;
searching existing data sources; gathering or maintaining the needed
data; and reviewing the information. Pursuant to 44 U.S.C.
3506(c)(2)(B), FRA solicits comments concerning: Whether these
information collection requirements are necessary for the proper
performance of the functions of FRA, including whether the information
has practical utility; the accuracy of FRA's estimates of the burden of
the information collection requirements; the quality, utility, and
clarity of the information to be collected; and whether the burden of
collection of information on those who are to respond, including
through the use of automated collection techniques or other forms of
information technology, may be minimized. For information or a copy of
the paperwork package submitted to OMB, contact Ms. Hodan Wells,
Information Clearance Officer, Federal Railroad Administration, at 202-
493-0440, or Ms. Kimberly Toone, Records Management Officer, Federal
Railroad Administration, at<PHONE_NUMBER>.
    Organizations and individuals desiring to submit comments on the
collection of information requirements should direct them to Ms. Hodan
Wells or Ms. Kimberly Toone, Federal Railroad Administration, 1200 New
Jersey Avenue SE, 3rd Floor, Washington, DC 20590. Comments may also be
submitted via email to Ms. Wells at<EMAIL_ADDRESS>or to Ms.
Toone at<EMAIL_ADDRESS>    OMB is required to make a decision concerning the collection of
information requirements contained in this proposed rule between 30 and
60 days after publication of this document in the Federal Register.
Therefore, a comment to OMB is best assured of having its full effect
if OMB receives it within 30 days of publication. The final rule will
respond to any OMB or public comments on the information collection
requirements contained in this proposal.

    FRA is not authorized to impose a penalty on persons for violating
information collection requirements that do not display a current OMB
control number, if required. FRA intends to obtain current OMB control
numbers for any new information collection requirements resulting from
this rulemaking action prior to the effective date of the final rule.
The OMB control number, when assigned, will be announced by separate
notice in the Federal Register.

D. Environmental Impact

    FRA has evaluated this proposed rule in accordance with its
``Procedures for
    Considering Environmental Impacts'' (FRA's Procedures) (64 FR
28545, (May 26, 1999)) as required by the National Environmental Policy
Act (42 U.S.C. 4321 et seq.), other environmental statutes, Executive
Orders, and related regulatory requirements. FRA has determined that
this proposed rule is not a major Federal action, requiring the
preparation of an environmental impact statement or environmental
assessment, because it is categorically excluded from detailed
environmental review pursuant to section 4(c)(20) of FRA's Procedures.
See 64 FR 28547 (May 26, 1999).
    In accordance with section 4(c) and (e) of FRA's Procedures, the
agency has further concluded that no extraordinary circumstances exist
with respect to this proposed rule that might trigger the need for a
more detailed environmental review. As a result, FRA finds that this
proposed rule is not a major Federal action significantly affecting the
quality of the human environment.

E. Federalism Implications

    Executive Order 13132, ``Federalism'' (64 FR 43255 (Aug. 10,
1999)), requires FRA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' are defined in the
Executive Order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.'' Under
Executive Order 13132, the agency may not issue a regulation with
federalism implications that imposes substantial direct compliance
costs and that is not required by statute, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by State and local governments or the agency consults
with State and local government officials early in the process of
developing the regulation. Where a regulation has federalism
implications and preempts State law, the agency seeks to consult with
State and local officials in the process of developing the regulation.
    FRA has analyzed this proposed rule in accordance with the
principles and criteria contained in Executive Order 13132. FRA has
determined that this final rule has no federalism implications, other
than the possible preemption of state laws under 49 U.S.C. 20106.
Therefore, the consultation and funding requirements of Executive Order
13132 do not apply, and preparation of a federalism summary impact
statement for the proposed rule is not required.

F. Unfunded Mandates Reform Act of 1995

    Pursuant to section 201 of the Unfunded Mandates Reform Act of 1995
(Pub. L. 104-4, 2 U.S.C. 1531), each Federal agency shall, unless
otherwise prohibited by law, assess the effects of Federal regulatory
actions on State, local, and tribal governments, and the private sector
(other than to the extent that such regulations incorporate
requirements specifically set forth in law). Section 202 of the Act (2
U.S.C. 1532) further requires that before promulgating any general
notice of proposed rulemaking that is likely to result in the
promulgation of any rule that includes any Federal mandate that may
result in expenditure by State, local, and tribal governments, in the
aggregate, or by the private sector, of $100,000,000 or more (adjusted
annually for inflation) in any one year, and before promulgating any
final rule for which a general notice of proposed rulemaking was
published, the agency shall prepare a written statement detailing the
effect on State, local, and tribal governments and the private sector.
This proposed rule would not result in such an expenditure, and thus
preparation of such a statement is not required.

G. Energy Impact

    Executive Order 13211 requires Federal agencies to prepare a
Statement of Energy Effects for any ``significant energy action.'' 66
FR 28355 (May 22, 2001). FRA evaluated this proposed rule in accordance
with Executive Order 13211 and determined that this regulatory action
is not a ``significant energy action'' within the meaning of the
Executive Order.
    Executive Order 13783, ``Promoting Energy Independence and Economic
Growth,'' requires Federal agencies to review regulations to determine
whether they potentially burden the development or use of domestically
produced energy resources, with particular attention to oil, natural
gas, coal, and nuclear energy resources. See 82 FR 16093 (March 31,
2017). FRA determined this proposed rule would not burden the
development or use of domestically produced energy resources.

H. Privacy Act Statement

    In accordance with 5 U.S.C. 553(c), DOT solicits comments from the
public to better inform its rulemaking process. DOT posts these
comments, without edit, to www.regulations.gov, as described in the
system of records notice, DOT/ALL-14 FDMS, accessible through
www.dot.gov/privacy. To facilitate comment tracking and response, we
encourage commenters to provide their name, or the name of their
organization; however, submission of names is completely optional.
Whether or not commenters identify themselves, all timely comments will
be fully considered. If you wish to provide comments containing
proprietary or confidential information, please contact the agency for
alternate submission instructions.

5. Amend Sec.  213.9 by revising paragraph (b) to read as follows:

Sec.  213.9  Classes of track: operating speed limits.

* * * * *
    (b) If a segment of track does not meet all of the requirements of
its intended class, it is reclassified to the next lowest class of
track for which it does meet all of the requirements of this part.
However, if the segment of track does not at least meet the
requirements of Class 1 track, operations may continue at Class 1
speeds for a period of not more than 30 days without bringing the track
into compliance, under the authority of a person designated under Sec.
213.7(a), after that person determines that operations may safely
continue and subject to any limiting conditions specified by such
person.

in this part, the work on the track shall be under the continuous
supervision of a person designated under Sec.  213.7(a), and (c) as
applicable, and subject to any limiting conditions specified by such
person. The operating speed cannot be more than the maximum allowable
speed under Sec.  213.9 for the class of track concerned. The term
``continuous supervision'' as used in this section means the physical
presence of that person at the job site. However, since the work may be
performed over a large area, it is not necessary that each phase of the
work be done under the visual supervision of that person.

devices may be used to supplement visual inspection. If a vehicle is
used for visual inspection, the speed of the vehicle may not be more
than 5 m.p.h. when traversing track crossings and turnouts; otherwise,
the inspection vehicle speed shall be at the sole discretion of the
inspector, based on track conditions and inspection requirements. When
traversing the track in a vehicle, the inspection will be subject to
the following conditions--
    (1) One inspector in a vehicle may inspect up to two tracks at one
time provided that the inspector's visibility remains unobstructed by
any cause and that the second track is not centered more than 30 feet
from the track the inspector traverses;
    (2) Two inspectors in one vehicle may inspect up to four tracks at
a time provided that the inspectors' visibility remains unobstructed by
any cause and that each track being inspected is centered within 39

11. Add Sec.  213.240 to read as follows:

Sec.  213.240   Continuous Rail Testing

    (a) Track owners may elect to use continuous rail testing to
satisfy the requirements for conducting internal rail inspections under
Sec.  213.237, or Sec.  213.339 where applicable. When a track owner
utilizes the continuous rail test inspection process under the
requirements of this section, the track owner is exempt from the
requirements of Sec.  213.113(b); all other requirements of Sec.
213.113 apply.
    (b) Track owners shall adopt the necessary procedures for
conducting continuous testing. At a minimum, the procedures must
conform to the requirements of this section and address:
    (1) How test data will be transmitted and analyzed;

    (2) How suspect locations will be identified for field
verification;
    (3) How suspect locations will be categorized and prioritized
according to their potential severity;
    (4) How suspect locations will be field-verified; and
    (5) How suspect locations will be designated following field
verification.
    (c) The track owner must designate and record the type of rail test
(continuous or stop-and-verify) to be conducted prior to commencing the
test over a track segment and make those records available to FRA upon
request during regular business hours following reasonable notice. If
the type of rail test changes following commencement of the test, the
change must be documented and include the time the test was started and
when it was changed, the milepost where the test started and where it
was changed, and the reason for the change. If the track owner intends
to conduct a continuous test, at least 10 days prior to commencement of
the test the track owner must designate and record whether the test is
being conducted to satisfy the requirements for an internal rail
inspection under Sec.  213.237, or Sec.  213.339 if applicable. This
documentation must be provided to FRA upon request during regular
business hours follow reasonable notice.
    (d)(1) Continuous rail test inspection vehicle operators must be
qualified under Sec.  213.238;
    (2) Internal rail inspection data collected during continuous rail
tests must be reviewed and interpreted by a person qualified to
interpret the equipment responses; and
    (3) All suspect locations must be field-verified by a person
qualified under Sec.  213.238.
    (e) At a minimum, the continuous rail test process must produce a
report containing a systematic listing of all suspected locations that
may contain any of the defects listed in the table in Sec.  213.113(c),
identified so that a person qualified under Sec.  213.238 can
accurately locate and field-verify each suspected defect.
    (1) Subject to the requirements of paragraphs (c)(2) and (3) of
this section, if the continuous rail test inspection vehicle indicates
a suspect location, field verification must be conducted within 72
hours of the completion of the test run, or within 84 hours of the
detection of the suspect location, whichever is earlier.
    (2) If the continuous rail test inspection vehicle indicates a
suspect location containing a suspected defect that, if verified,
requires remedial action A, A2, or B identified in the table contained
in Sec.  213.113(c), the track owner must field-verify the suspect
location no more than 24 hours after the completion of the test run, or
36 hours from detection of the suspect location, whichever is earlier.
    (3) If the continuous rail test inspection vehicle indicates a
broken rail with rail separation, the track owner must have procedures
to ensure that adequate protection is immediately implemented.
    (4) A suspect location is not considered a defect under Sec.
213.113(c) until it has been field-verified by a person qualified under
