Appendix B to Part 234--Alternate Methods of Protection Under 49 CFR
234.105(c), 234.106, and 234.107(c).
Authority: 49 U.S.C. 20103, 20107, and 49 CFR 1.49.
Source: 61 FR 31806, June 20, 1996, unless otherwise noted.
Subpart A--General
Sec. 234.1 Scope.
This part imposes minimum maintenance, inspection, and testing
standards for highway-rail grade crossing warning systems. This part
also prescribes standards for the reporting of failures of such systems
and prescribes minimum actions railroads must take when such warning
systems malfunction. This part does not restrict a railroad from
adopting and enforcing additional or more stringent requirements not
inconsistent with this part.
Sec. 234.3 Application.
This part applies to all railroads except:
(a) A railroad that exclusively operates freight trains only on
track which is not part of the general railroad system of
transportation;
(b) Rapid transit operations within an urban area that are not
connected to the general railroad system of transportation; and
(c) A railroad that operates passenger trains only on track inside
an installation that is insular; i.e., its operations are limited to a
separate enclave in such a way that there is no reasonable expectation
that the safety of the public--except a business guest, a licensee of
the railroad or an affiliated entity, or a trespasser--would be affected
by the operation. An operation will not be considered insular if one or
more of the following exists on its line:
(1) A public highway-rail crossing that is in use;
(2) An at-grade rail crossing that is in use;
(3) A bridge over a public road or waters used for commercial
navigation; or
(4) A common corridor with a railroad, i.e., its operations are
within 30 feet of those of any railroad.
Sec. 234.4 Preemptive effect.
Under 49 U.S.C. 20106 (formerly Sec. 205 of the Federal Railroad
Safety Act of 1970 (45 U.S.C. 434)), issuance of these regulations
preempts any State law, rule, regulation, order, or standard covering
the same subject matter, except a provision directed at an essentially
local safety hazard that is consistent with this part and that does not
impose an undue burden on interstate commerce.
Sec. 234.5 Definitions.
As used in this part:
Activation failure means the failure of an active highway-rail grade
crossing warning system to indicate the approach of a train at least 20
seconds prior to the train's arrival at the crossing, or to indicate the
presence of a train occupying the crossing, unless the crossing is
provided with an alternative means of active warning to highway users of
approaching trains. (This failure indicates to the motorist
[[Page 486]]
that it is safe to proceed across the railroad tracks when, in fact, it
is not safe to do so.) A grade crossing signal system does not indicate
the approach of a train within the meaning of this paragraph if--more
than 50% of the flashing lights (not gate arm lights) on any approach
lane to the crossing are not functioning as intended, or in the case of
an approach lane for which two or more pairs of flashing lights are
provided, there is not at least one flashing light pair operating as
intended. Back lights on the far side of the crossing are not considered
in making these determinations.
Appropriately equipped flagger means a person other than a train
crewmember who is equipped with a vest, shirt, or jacket of a color
appropriate for daytime flagging such as orange, yellow, strong yellow
green or fluorescent versions of these colors or other generally
accepted high visibility colors. For nighttime flagging, similar outside
garments shall be retro reflective. Acceptable hand signal devices for
daytime flagging include `` STOP/SLOW'' paddles or red flags. For
nighttime flagging, a flashlight, lantern, or other lighted signal shall
be used. Inasmuch as Part VI of the Federal Highway Administration's
Manual on Uniform Traffic Control Devices addresses standards and guides
for flaggers and flagging equipment for highway traffic control, FRA
recommends that railroads be aware of the standards and follow them to
the greatest extent possible. Copies of the latest MUTCD provisions
regarding flagging will be available from FRA, as well as FMCSA, as
changes are made in this area.
Credible report of system malfunction means specific information
regarding a malfunction at an identified highway-rail crossing, supplied
by a railroad employee, law enforcement officer, highway traffic
official, or other employee of a public agency acting in an official
capacity.
False activation means the activation of a highway-rail grade
crossing warning system caused by a condition that requires correction
or repair of the grade crossing warning system. (This failure indicates
to the motorist that it is not safe to cross the railroad tracks when,
in fact, it is safe to do so.)
Highway-rail grade crossing means a location where a public highway,
road, street, or private roadway, including associated sidewalks and
pathways, crosses one or more railroad tracks at grade.
Partial activation means activation of a highway-rail grade crossing
warning system indicating the approach of a train, however, the full
intended warning is not provided due to one of the following conditions:
(1) At non-gated crossings equipped with one pair of lights designed
to flash alternately, one of the two lights does not operate properly
(and approaching motorists can not clearly see flashing back lights from
the warning lights on the other side of the crossing);
(2) At gated crossings, the gate arm is not in a horizontal
position; or
(3) At gated crossings, any portion of a gate arm is missing if that
portion normally had a gate arm flashing light attached.
Train means one or more locomotives, with or without cars.
Warning system malfunction means an activation failure, a partial
activation, or a false activation of a highway-rail grade crossing
warning system.
Sec. 234.6 Penalties.
(a) Civil penalty. Any person (an entity of any type covered under 1
U.S.C. 1, including but not limited to the following: a railroad; a
manager, supervisor, official, or other employee or agent of a railroad;
any owner, manufacturer, lessor, or lessee of railroad equipment, track,
or facilities; any independent contractor providing goods or services to
a railroad; and any employee of such owner, manufacturer, lessor,
lessee, or independent contractor) who violates any requirement of this
part or causes the violation of any such requirement is subject to a
civil penalty of at least $500, but not more than $11,000 per violation,
except that: penalties may be assessed against individuals only for
willful violations, and where a grossly negligent violation or a pattern
of repeated violations has created an imminent hazard of death or injury
to persons, or has caused death or injury, a penalty not to exceed
$22,000 per violation may be assessed. Each day a violation continues
shall
[[Page 487]]
constitute a separate offense. Appendix A to this part contains a
schedule of civil penalty amounts used in connection with this rule. The
railroad is not responsible for compliance with respect to any condition
inconsistent with the technical standards set forth in this part where
such variance arises as a result of actions beyond the control of the
railroad and the railroad could not have prevented the variance through
the exercise of due diligence. The foregoing sentence does not excuse
any instance of noncompliance resulting from the actions of the
railroad's employees, agents, or contractors.
(b) Criminal penalty. Whoever knowingly and willfully makes, causes
to be made, or participates in the making of a false entry in reports
required to be filed by this part, or files a false report or other
document required to be filed by this part is subject to a $5,000 fine
and 2 years imprisonment as prescribed by 49 U.S.C. 522(a) and section
209(e) of the Federal Railroad Safety Act of 1970, as amended (45 U.S.C.
438(e)).

the railroad shall provide alternative means of warning highway traffic
and railroad employees in accordance with Secs. 234.105, 234.106 or
234.107 of this part.
(c) Nothing in this subpart requires repair of a warning system, if,
acting in accordance with applicable State law, the railroad proceeds to
discontinue or dismantle the warning system. However, until repair,
correction, discontinuance, or dismantling of the warning system is
completed, the railroad shall comply with this subpart to ensure the
safety of the traveling public and railroad employees.
[[Page 488]]
Sec. 234.105 Activation failure.
Upon receipt of a credible report of warning system malfunction
involving an activation failure, a railroad having maintenance
responsibility for the warning system shall promptly initiate efforts to
warn highway users and railroad employees at the subject crossing by
taking the following actions:
(a) Prior to any train's arrival at the crossing, notify the train
crew of the report of activation failure and notify any other railroads
operating over the crossing;
(b) Notify the law enforcement agency having jurisdiction over the
crossing, or railroad police capable of responding and controlling
vehicular traffic; and
(c) Provide for alternative means of actively warning highway users
of approaching trains, consistent with the following requirements (see
appendix B for a summary chart of alternative means of warning):
(1)(i) If an appropriately equipped flagger provides warning for
each direction of highway traffic, trains may proceed through the
crossing at normal speed.
(ii) If at least one uniformed law enforcement officer (including a
railroad police officer) provides warning to highway traffic at the
crossing, trains may proceed through the crossing at normal speed.
(2) If an appropriately equipped flagger provides warning for
highway traffic, but there is not at least one flagger providing warning
for each direction of highway traffic, trains may proceed with caution
through the crossing at a speed not exceeding 15 miles per hour. Normal
speed may be resumed after the locomotive has passed through the
crossing.
(3) If there is not an appropriately equipped flagger or uniformed
law enforcement officer providing warning to highway traffic at the
crossing, each train must stop before entering the crossing and permit a
crewmember to dismount to flag highway traffic to a stop. The locomotive
may then proceed through the crossing, and the flagging crewmember may
reboard the locomotive before the remainder of the train proceeds
through the crossing.
(d) A locomotive's audible warning device shall be activated in
accordance with railroad rules regarding the approach to a grade
crossing.
Sec. 234.106 Partial activation.
Upon receipt of a credible report of a partial activation, a
railroad having maintenance responsibility for the warning system shall
promptly initiate efforts to warn highway users and railroad employees
at the subject crossing in the same manner as required for false
activations (Sec. 234.107).
Sec. 234.107 False activation.
Upon receipt of a credible report of a false activation, a railroad
having maintenance responsibility for the highway-rail grade crossing
warning system shall promptly initiate efforts to warn highway users and
railroad employees at the crossing by taking the following actions:
(a) Prior to a train's arrival at the crossing, notify the train
crew of the report of false activation and notify any other railroads
operating over the crossing;
(b) Notify the law enforcement agency having jurisdiction over the
crossing, or railroad police capable of responding and controlling
vehicular traffic; and
(c) Provide for alternative means of actively warning highway users
of approaching trains, consistent with the following requirements (see
Appendix B for a summary chart of alternative means of warning).
(1)(i) If an appropriately equipped flagger is providing warning for
each direction of highway traffic, trains may proceed through the
crossing at normal speed.
(ii) If at least one uniformed law enforcement officer (including a
railroad police officer) provides warning to highway traffic at the
crossing, trains may proceed through the crossing at normal speed.
(2) If there is not an appropriately equipped flagger providing
warning for each direction of highway traffic, or if there is not at
least one uniformed law enforcement officer providing warning, trains
with the locomotive or cab car leading, may proceed with caution
[[Page 489]]
through the crossing at a speed not exceeding 15 miles per hour. Normal
speed may be resumed after the locomotive has passed through the
crossing. In the case of a shoving move, a crewmember shall be on the
ground to flag the train through the crossing.
(3) In lieu of complying with paragraphs (c) (1) or (2) of this
section, a railroad may temporarily take the warning system out of
service if the railroad complies with all requirements of Sec. 234.105,
``Activation failure.''
(d) A locomotive's audible warning device shall be activated in
accordance with railroad rules regarding the approach to a grade
crossing.
Sec. 234.109 Recordkeeping.
(a) Each railroad shall keep records pertaining to compliance with
this subpart. Records may be kept on forms provided by the railroad or
by electronic means. Each railroad shall keep the following information
for each credible report of warning system malfunction:
(1) Location of crossing (by highway name and DOT/AAR Crossing
Inventory Number);
(2) Time and date of receipt by railroad of report of malfunction;
(3) Actions taken by railroad prior to repair and reactivation of
repaired system; and
(4) Time and date of repair.
(b) Each railroad shall retain for at least one year (from the
latest date of railroad activity in response to a credible report of
malfunction) all records referred to in paragraph (a) of this section.
Records required to be kept shall be made available to FRA as provided
by 49 U.S.C. 20107 (formerly 208 of the Federal Railroad Safety Act of
1970 (45 U.S.C. 437)).

Sec. 234.265 Timing relays and timing devices.
Each timing relay and timing device shall be tested at least once
every twelve months. The timing shall be maintained at not less than 90
percent nor more than 110 percent of the 41 predetermined time interval.
The predetermined time interval shall be shown on the plans or marked on
the timing relay or timing device. Timing devices which perform internal
functions associated with motion detectors, motion sensors, and grade
crossing predictors are not subject to the requirements of this section.
Sec. 234.267 Insulation resistance tests, wires in trunking and cables.
(a) Insulation resistance tests shall be made when wires or cables
are installed and at least once every ten years thereafter.
(b) Insulation resistance tests shall be made between all conductors
and ground, between conductors in each multiple conductor cable, and
between conductors in trunking. Insulation resistance tests shall be
performed when wires, cables, and insulation are dry.
(c) Subject to paragraph (d) of this section, when insulation
resistance of wire or cable is found to be less than 500,000 ohms,
prompt action shall be taken to repair or replace the defective wire or
cable. Until such defective wire or cable is replaced, insulation
resistance tests shall be made annually.
(d) A circuit with a conductor having an insulation resistance of
less than 200,000 ohms shall not be used.
(e) Required insulation resistance testing that does not conform to
the required testing schedule of this section shall be completed in
accordance with the following schedule:
(1) Not less than 50% by the end of calendar year 1996;
(2) Not less than a total of 75% by the end of calendar year 1997;
and
(3) One hundred percent by the end of calendar year 1998.
Sec. 234.269 Cut-out circuits.
Each cut-out circuit shall be tested at least once every three
months to determine that the circuit functions as intended. For purposes
of this section, a cut-out circuit is any circuit which overrides the
operation of automatic warning systems. This includes both switch cut-
out circuits and devices which enable personnel to manually override the
operation of automatic warning systems.
Sec. 234.271 Insulated rail joints, bond wires, and track connections.
Insulated rail joints, bond wires, and track connections shall be
inspected at least once every three months.
Sec. 234.273 Results of inspections and tests.
(a) Results of inspections and tests made in compliance with this
part shall be recorded on forms provided by the railroad, or by
electronic means, subject to approval by the Associate Administrator for
Safety. Each record shall show the name of the railroad, AAR/DOT
inventory number, place and date, equipment tested, results of tests,
repairs, replacements, adjustments made, and condition in which the
apparatus was left.
(b) Each record shall be signed or electronically coded by the
employee making the test and shall be filed in the office of a
supervisory official having jurisdiction. Records required to be kept
shall be made available to FRA as provided by 49 U.S.C. 20107 (formerly
Sec. 208 of the Federal Railroad Safety Act of 1970 (45 U.S.C. 437)).
(c) Each record shall be retained until the next record for that
test is filed but in no case for less than one year from the date of the
test.
