Part 134-Signal Failure Reports

MONTHLY REPORT OF FAILURE OF BLOCK SIGNAL SYSTEMS, IN7TER-
LOCKING, AUTOMATIC TRAIN STOP, TRAIN CONTROL, AND CAB
SIGNAL DEVICES, AND OTHER SIMILAR APPLIANCES, METHODS,
AND SYSTEMS TO INDICATE OR FUNCTION AS INTENDED

C)RDER

.Lt a Session of the Interstate Commercee C'ummission, Div'ision 3, held at its
office in Wasuhington, D. C., on the 18th day of May A. D. 1954.
The matter of revising Formrs 1, 2, and 3 entitled "Signal Falilure Report" and
the method embodied in the instructions therein set forth being under
consideration :
It appearing, That carriers are presently required to furnish information on
Forms 1 and 2, some of which is no longer needed or necessary, and in order
that such information no longer required may be eliminated from said forms
and related instructions,
It is ordered, That the said Forms 1, 2, and 3 be and they are hereby con-
solidated and revised in the matter indicated by the following accompanying
forms:
I 134.1 Lial of forms.
1. Signal failure report.
2. Instructions.
And it is further ordered, That this order shall become effective on the flrat
dlay of October A. D. 1954.
(See. 12, 24 Stat. 383, as amended; 49 U. B. C. 12. Interprets or applies see.

INSTRUCTIONS
1. A report in accordance with the method and form prescribed must be sent
to the Interstate Commerce Commission, Bureau of Safety and Service, Wash-
ington, D. C., for each month, showing all failures of block-signal systems, inter-
locking, automatic train-stop, train-control, and cab-signal devices, and other
similar appliances, methods, and systems, to indicate or function as intended,
such report to be filed with the Commission within 30 days after the end of the
month for which the report is made.
2. Report shall include all failures of the specified devices on the line of the
reporting carrier.

3. The name of the reporting carrier, the month covered by' the report and
rthe railroad; r~egioa, dlivision, system or device, covered by this report should be
given inl the spaces provided.
4l. Under "ClawsSfication," and under "False restrictiv-e failures" in columns
'1. ", 3l, and 41 should be shown the number of false restrictive failures of block-
spinal systems, interlocking, automatic train stop, traini control, and cab sigmi~le,
and other~sPitiiilar appliances, methods, and systems, respectively, and in column
,5 the total number of these failures.
3. A false restrictive failure is a failure of a system, device or appliance to
indicate or function as intended which results in greater restriction than is
requi red.
G. Under '"Classitic~ation,, and under "FaRlse plroceeld failures" in columns 6, 7,
t;, and 9 should be shown thle number of false proceed failures of block-signal
systems, interlocking, automatic train stop, train control, and cab signals, and
other similar appliances, nwethods, andl systems, respectively, and in column 10 the
total number of these failures.
7. A false proceed failure is a failure of a system, device. or appliance to
indicate or function as intended which results in less restriction than is
required.
8. Under "Classification," and under ''Potential false proceed conditions" in
columns 11, 12, 13, and 14 should be shown the number of potential false
proceed conditions in block-signal systems, interlocking, automatic train stop,
train control, and cab signals, and other similar appliances, methods, and
systems, respectively, and in column 15 the total number of these conditions.
9. Potential false proceed conditions include conditions of apparatus existing
whlen no train is present, under which a false proceed failure would have
occurred had a locomotive or train approached or entered a section of track
occupied by another train or where the safety of the track was impaired.
10. Except as set forth in paragraph 11, a failure should not be counted more
thain once in columns 1, 2, 3, 4, 6, 7, 8, and 9: the failure should be classified
under the basic system or appliance of which it forms an essential part. For
example, assume a broken rail bond within interlocking limits which prevents
a homle signal from being cleared and causes the automatic block signal in rear
to display approach, as well as correspondling indications of a cab-signal system
otn each train appronebing this point. Such failure should be included in column
2 under interlocking.
11. WChen a condition producing failures extends over a period of more than 24
hours, one failure should be reportedly for the first 24 hours, and an additional
failure for each succeeding 24-hour period until necessary repairs are made.
Should failures of automatic train-stop, train-control, or cab-signal devices occur
o11n more than one trip due to the same defective condition of locomotive ap-
paratus, one failure should be reported for each trip made by the locomotive on
which suich failures occur until implroper condition is corrected.
''12. Under "'Remark~s" identify the other appDliances, methods and systems for
which "False r~estrictive failures" are reported in column 4. Do not report in
column 4t failures of traffic-control systems, as such failures should be reported
under "Block systems" or "Interlocking."
13, Under "Description of False Proceed Failures or Potential False Proceed
Conditions"': In column 16 show the faiFures, numbered consecutively by rail-
road, region, or division; in column 17i, the date; in column 18, the number of the
'locomotive involved (and initials if foreign) if failure involves automatic train-
stop, train-control, or cab-signal devices; in column 19, the signal number, switch










number, roaidway or interlocking location ; and in column 20, the kind of failure,
whether false p~roc~eed, or whether a potential false proceed condition. In column
21 showf the nature and cause of failure, indicating when moe thianr one of the
systems, devices and applirnnees listed is afftectedl by a single failure. See
example, paragraph 10.
1-1. The date, signature, a~nd tite of the r~eporting oflicer must be given on
the line provided for that purpose at the bottom of the form.
15. Copies of the prescribed formo and instructions will be furnished upon
application to the Bureau of Safety and Service.
16. The follorwing: abbreviations may be used ~in. the report:
A, Automatic. EP~, E~lectropneumatic.
AB, Automatic block. FcP, False proceed.
ACS, Automatic cab signal. F`R, False restrictive.
APB, Absolute permissive block. AI, Mlanual block.
