              Subpart C_Inspection and Testing Requirements

 

Sec. 232.205  Class I brake test-initial terminal inspection.



    (a) Each train and each car in the train shall receive a Class I 

brake test as described in paragraph (c) of this section by a qualified 

person, as defined in Sec. 232.5, at the following points:

    (1) The location where the train is originally assembled (``initial 

terminal'');

    (2) A location where the train consist is changed other than by:

    (i) Adding a single car or a solid block of cars, except as provided 

in paragraph (b)(2) of this section;

    (ii) Removing a single car or a solid block of cars;

    (iii) Removing cars determined to be defective under this chapter; 

or

    (iv) A combination of the changes listed in paragraphs (a)(2)(i) 

through (a)(2)(iii) of this section (See Sec. Sec. 232.209 and 232.211 

for requirements related to the pick-up of cars and solid blocks of cars 

en route.);

    (3) A location where the train is off air for a period of more than 

four hours;

    (4) A location where a unit or cycle train has traveled 3,000 miles 

since its last Class I brake test; and

    (5) A location where the train is received in interchange if the 

train consist is changed other than by:

    (i) Removing a car or a solid block of cars from the train;

    (ii) Adding a previously tested car or a previously tested solid 

block of cars to the train;

    (iii) Changing motive power;

    (iv) Removing or changing the caboose; or

    (v) Any combination of the changes listed in paragraphs (a)(5) of 

this section.

    (A) If changes other than those contained in paragraph (a)(5)(i)-

(a)(5)(v) of this section are made to the train consist when it is 

received in interchange and the train will move 20 miles or less, then 

the railroad may conduct a

brake test pursuant to Sec. 232.209 on those cars added to the train.

    (B) [Reserved]

    (b) Except as provided in Sec. 232.209, each car and each solid 

block of cars added to a train shall receive a Class I brake test as 

described in paragraph (c) of this section at the location where it is 

added to a train unless:

    (1) The solid block of cars is comprised of cars from a single 

previous train, the cars of which have previously received a Class I 

brake test and have remained continuously and consecutively coupled 

together with the train line remaining connected, other than for 

removing defective equipment, since being removed from its previous 

train and have not been off air for more than four hours; or

    (2) The solid block of cars is comprised of cars from a single 

previous train, the cars of which were required to be separated into 

multiple solid blocks of cars due to space or trackage constraints at a 

particular location when removed from the previous train, provided the 

cars have previously received a Class I brake test, have not been off 

air more than four hours, and the cars in each of the multiple blocks of 

cars have remained continuously and consecutively coupled together with 

the train line remaining connected, except for the removal of defective 

equipment. Furthermore, these multiple solid blocks of cars shall be 

added to a train in the same relative order (no reclassification) as 

when removed from the previous train, except for the removal of 

defective equipment.

    (c) A Class I brake test of a train shall consist of the following 

tasks and requirements:

    (1) Brake pipe leakage shall not exceed 5 psi per minute or air flow 

shall not exceed 60 cubic feet per minute (CFM).

    (i) Leakage Test. The brake pipe leakage test shall be conducted as 

follows:

    (A) Charge the air brake system to the pressure at which the train 

will be operated, and the pressure at the rear of the train shall be 

within 15 psi of the pressure at which the train will be operated, but 

not less than 75 psi, as indicated by an accurate gauge or end-of-train 

device at the rear end of train;

    (B) Upon receiving the signal to apply brakes for test, make a 20-

psi brake pipe service reduction;

    (C) If the locomotive used to perform the leakage test is equipped 

with a means for maintaining brake pipe pressure at a constant level 

during a 20-psi brake pipe service reduction, this feature shall be cut 

out during the leakage test; and

    (D) With the brake valve lapped and the pressure maintaining feature 

cut out (if so equipped) and after waiting 45-60 seconds, note the brake 

pipe leakage as indicated by the brake-pipe gauge in the locomotive, 

which shall not exceed 5 psi per minute.

    (ii) Air Flow Method Test. When a locomotive is equipped with a 26-L 

brake valve or equivalent pressure maintaining locomotive brake valve, a 

railroad may use the Air Flow Method Test as an alternate to the brake 

pipe leakage test. The Air Flow Method (AFM) Test shall be performed as 

follows:

    (A) Charge the air brake system to the pressure at which the train 

will be operated, and the pressure at the rear of the train shall be 

within 15 psi of the pressure at which the train will be operated, but 

not less than 75 psi, as indicated by an accurate gauge or end-of-train 

device at the rear end of train; and

    (B) Measure air flow as indicated by a calibrated AFM indicator, 

which shall not exceed 60 cubic feet per minute (CFM).

    (iii) The AFM indicator shall be calibrated for accuracy at periodic 

intervals not to exceed 92 days. The AFM indicator calibration test 

orifices shall be calibrated at temperatures of not less than 20 degrees 

Fahrenheit. AFM indicators shall be accurate to within  3 standard cubic feet per minute (CFM).

    (2) The inspector(s) shall take a position on each side of each car 

sometime during the inspection process so as to be able to examine and 

observe the functioning of all moving parts of the brake system on each 

car in order to make the determinations and inspections required by this 

section. A ``roll-by'' inspection of the brake release as provided for 

in paragraph (b)(8) of this



[[Page 541]]



section shall not constitute an inspection of that side of the train for 

purposes of this requirement;

    (3) The train brake system shall be charged to the pressure at which 

the train will be operated, and the pressure at the rear of the train 

shall be within 15 psi of the pressure at which the train will be 

operated, but not less than 75 psi, angle cocks and cutout cocks shall 

be properly positioned, air hoses shall be properly coupled and shall 

not kink, bind, or foul or be in any other condition that restricts air 

flow. An examination must be made for leaks and necessary repairs made 

to reduce leakage to the required minimum. Retaining valves and 

retaining valve pipes shall be inspected and known to be in proper 

condition for service;

    (4) The brakes on each car shall apply in response to a 20-psi brake 

pipe service reduction and shall remain applied until a release of the 

air brakes has been initiated by the controlling locomotive or yard test 

device. The brakes shall not be applied or released until the proper 

signal is given. A car found with brakes that fail to apply or remain 

applied may be retested and remain in the train if the retest is 

conducted at an air pressure that is within 15 psi of the air pressure 

at which the train will be operated. The retest may be conducted from 

either the controlling locomotive, the head-end of the consist, or with 

a suitable test device, as described in Sec. 232.217(a), positioned at 

one end of the car(s) being retested, and the brakes shall remain 

applied until a release is initiated after a period which is no less 

than three minutes. If the retest is performed at the car(s) being 

retested with a suitable device, the compressed air in the car(s) shall 

be depleted prior to disconnecting the hoses between the car(s) to 

perform the retest;

    (5) For cars equipped with 8\1/2\-inch or 10-inch diameter brake 

cylinders, piston travel shall be within 7 to 9 inches. If piston travel 

is found to be less than 7 inches or more than 9 inches, it must be 

adjusted to nominally 7\1/2\ inches. For cars not equipped with 8\1/2\-

inch or 10-inch diameter brake cylinders, piston travel shall be within 

the piston travel stenciled or marked on the car or badge plate. Minimum 

brake cylinder piston travel of truck-mounted brake cylinders must be 

sufficient to provide proper brake shoe clearance when the brakes are 

released. Piston travel must be inspected on each freight car while the 

brakes are applied;

    (6) Brake rigging shall be properly secured and shall not bind or 

foul or otherwise adversely affect the operation of the brake system;

    (7) All parts of the brake equipment shall be properly secured. On 

cars where the bottom rod passes through the truck bolster or is secured 

with cotter keys equipped with a locking device to prevent their 

accidental removal, bottom rod safety supports are not required; and

    (8) When the release is initiated by the controlling locomotive or 

yard test device, the brakes on each freight car shall be inspected to 

verify that it did release; this may be performed by a ``roll-by'' 

inspection. If a ``roll-by'' inspection of the brake release is 

performed, train speed shall not exceed 10 MPH and the qualified person 

performing the ``roll-by'' inspection shall communicate the results of 

the inspection to the operator of the train. The operator of the train 

shall note successful completion of the release portion of the 

inspection on the record required in paragraph (d) of this section.

    (d) Where a railroad's collective bargaining agreement provides that 

a carman is to perform the inspections and tests required by this 

section, a carman alone will be considered a qualified person. In these 

circumstances, the railroad shall ensure that the carman is properly 

trained and designated as a qualified person or qualified mechanical 

inspector pursuant to the requirements of this part.

    (e) A railroad shall notify the locomotive engineer that the Class I 

brake test was satisfactorily performed and provide the information 

required in this paragraph to the locomotive engineer or place the 

information in the cab of the controlling locomotive following the test. 

The information required by this paragraph may be provided to the 

locomotive engineer by any means determined appropriate by the railroad; 

however, a written or electronic record of the information



[[Page 542]]



shall be retained in the cab of the controlling locomotive until the 

train reaches its destination. The written or electronic record shall 

contain the date, time, number of freight cars inspected, and identify 

the qualified person(s) performing the test and the location where the 

Class I brake test was performed.

    (f) Before adjusting piston travel or working on brake rigging, 

cutout cock in brake pipe branch must be closed and air reservoirs must 

be voided of all compressed air. When cutout cocks are provided in brake 

cylinder pipes, these cutout cocks only may be closed and air reservoirs 

need not be voided of all compressed air.
