49 CFR § 232.205 - Class I brake test-initial terminal inspection.
§ 232.205 Class I brake test-initial terminal inspection .
( a ) Each trail and each car in the string shall receive a class I brake screen as described in paragraph ( degree centigrade ) of this section by a qualify person, as defined in § 232.5, at the come points :
( 1 ) The placement where the educate is primitively assembled ( “ initial concluding ” ) ;
( 2 ) A location where the string consist is changed other than by :

( i ) Adding a individual car or a solid block of cars, except arsenic provided in paragraph ( bel ) ( 2 ) of this section ;
( two ) Removing a individual car or a solid block of cars ;
( three ) Removing cars determined to be defective under this chapter ; or
( intravenous feeding ) A combination of the changes listed in paragraph ( a ) ( 2 ) ( one ) through ( a ) ( 2 ) ( three ) of this segment ( See §§ 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 24 hours .
( 4 ) A localization where a whole or cycle train has traveled 3,000 miles since its last class I brake test ; and
( 5 ) A location where the prepare is received in exchange if the train dwell is changed other than by :
( one ) Removing a car or a solid block of cars from the trail ;
( two ) Adding a previously tested car or a previously tested solid block of cars to the train ;
( three ) Changing motivation ability ;
( four ) Removing or changing the cabin car ; or
( five ) Any combination of the changes listed in paragraph ( a ) ( 5 ) of this section .
( A ) If changes other than those contained in paragraph ( a ) ( 5 ) ( one ) – ( a ) ( 5 ) ( volt ) of this incision are made to the gearing consist when it is received in counterchange and the caravan will move 20 miles or less, then the railroad may conduct a brake test pursuant to § 232.209 on those cars added to the educate .
( B ) [ Reserved ]
( b-complex vitamin ) Except american samoa provided in § 232.209, each car and each solid obstruct of cars added to a prepare shall receive a class I brake test as described in paragraph ( c ) of this section at the location where it is added to a educate unless :
( 1 ) The solid block of cars is comprised of cars from a individual previous caravan, the cars of which have previously received a class I brake trial and have remained continuously and consecutively coupled together with the train wrinkle remaining connected, early than for removing bad equipment, since being removed from its previous gearing and have not been off-air for more than 24 hours ; or
( 2 ) The solid block of cars is comprised of cars from a single previous prepare, the cars of which were required to be separated into multiple solid blocks of cars ascribable to space or trackage constraints at a particular placement when removed from the former train, provided the cars have previously received a class I brake test, have not been off-air more than 24 hours, and the cars in each of the multiple blocks of cars have remained continuously and consecutively coupled together with the coach credit line remaining connected, except for the removal of defective equipment. furthermore, these multiple solid blocks of cars shall be added to a gearing in the same proportional order ( no reclassification ) as when removed from the former train, except for the removal of defective equipment .
( hundred ) A class I brake test of a train shall consist of the succeed tasks and requirements :
( 1 ) Brake pipe escape shall not exceed 5 psi per hour or air flow shall not exceed 60 cubic feet per hour ( CFM ) .
( iodine ) escape Test. The brake shriek escape quiz shall be conducted as follows :
( A ) commit the air brake system to the pressure at which the train will be operated, and the blackmail at the rear of the prepare shall be within 15 psi of the press 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 gearing ;
( B ) Upon receiving the signal to apply brakes for test, make a 20-psi brake shriek service decrease ;

( C ) If the locomotive used to perform the escape test is equipped with a means for maintaining brake pipe imperativeness at a constant level during a 20-psi brake pipe service reduction, this feature of speech shall be cut out during the escape test ; and
( D ) With the brake valve lapped and the pressure maintaining sport cut out ( if so equipped ) and after waiting 45-60 seconds, note the brake pipe escape as indicated by the brake-pipe gauge in the locomotive, which shall not exceed 5 psi per minute .
( two ) Air Flow Method Test. When a locomotive is equipped with a 26-L brake valve or equivalent blackmail maintaining locomotive brake valve, a dragoon may use the Air Flow Method Test as an surrogate to the brake organ pipe escape test. The Air Flow Method ( AFM ) Test shall be performed as follows :
( A ) charge the air travel brake system to the blackmail at which the gearing will be operated, and the pressure at the rear of the educate shall be within 15 pounds per square inch of the press at which the string will be operated, but not less than 75 pounds per square inch, as indicated by an accurate gauge or end-of-train device at the rear conclusion of train ; and
( B ) Use a calibrate AFM indicator to measure air travel flow. A aim equipped with at least one distribute baron unit or an breeze repeater unit providing a source of brake pipe control air from two or more locations must not exceed a compound menstruation of 90 cubic feet per moment ( CFM ). Otherwise, the air travel flow must not exceed 60 CFM. Railroads must develop and implement operate rules to ensure compliant operation of a string if air flow exceeds these parameters after the class I brake test is completed .
( three ) The AFM indicator must be calibrated for accuracy at periodic intervals not to exceed 92 days. The AFM index and all test orifices must be calibrated at temperatures of not less than 20 °F. AFM indicators must be accurate to within ±3 standard cubic feet per minute ( CFM ) at 60 CFM air travel flow .
( intravenous feeding ) For each AFM indicator, its survive date of calibration must be recorded and certified on Form F6180-49A .
( vanadium ) An AFM indicator not incompliance with this depart must :
( A ) not be used, including in the performance of a escape test or to aid in the control or brake of the trail ;
( B ) Be tagged in accordance with § 232.15 ( boron ) and include text that it is “ inoperative ” or “ delinquent ” ; and
( C ) Be placed with its tag in a blatant placement of the controlling locomotive cab .
( 2 ) The examiner ( south ) shall take a placement 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 decree to make the determinations and inspections required by this section. A “ roll-by ” inspection of the brake release as provided for in paragraph ( bacillus ) ( 8 ) of this department shall not constitute an inspection of that side of the prepare for purposes of this requirement ;
( 3 ) The coach brake system shall be charged to the coerce at which the string will be operated, and the press 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 by rights positioned, air hoses shall be properly coupled and shall not kink, bind, or foul or be in any early stipulate that restricts air hang. An interrogation must be made for leaks and necessity repairs made to reduce escape to the command minimum. Retaining valves and retaining valve pipes shall be inspected and known to be in proper condition for military service ;
( 4 ) The brakes on each car shall apply in reception to a 20-psi brake pipe military service reduction and shall remain use until a liberation 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 bespeak is given. A car found with brakes that fail to apply or remain apply may be retested and remain in the train if the retest is conducted at an air travel blackmail that is within 15 pounds per square inch of the breeze pressure at which the educate will be operated. The retest may be conducted from either the controlling locomotive, the head-end of the consist, or with a desirable test device, as described in § 232.217 ( a ), positioned at one end of the cable car ( randomness ) being retested, and the brakes shall remain use until a release is initiated after a period which is no less than three minutes. If the retest is performed at the car ( second ) being retested with a suitable device, the compress air travel in the car ( mho ) shall be depleted anterior to disconnecting the hoses between the cable car ( second ) to perform the retest ;
( 5 ) For cars equipped with 8 1/2-inch or 10-inch diameter brake cylinders, piston travel shall be within 6 to 9 inches. If piston travel is found to be less than 6 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 change of location shall be within the piston travel stenciled or marked on the car or badge plate. Minimum brake cylinder piston travel of truck-mounted bracken cylinders must be sufficient to provide proper brake horseshoe 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 penetrate rod passes through the hand truck bolster or is secured with cotter keys equipped with a locking device to prevent their accidental removal, buttocks rod base hit supports are not required ; and
( 8 ) When the acquittance is initiated by the controlling locomotive or yard test device, the brakes on each freight car shall be inspected to verify that it did unblock ; 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 restricted 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 secrete assign of the inspection on the criminal record required in paragraph ( vitamin d ) of this department .
( 9 ) Although an air repeater unit is not a locomotive or gear under part 229, an breeze repeater unit operated in accordance with this part must :
( one ) Receive an inspection in accord with § 229.21 where and when an inspection is required in accordance with § 232.205 ( a ) ( 1 ) ; and
( two ) otherwise comply with part 229 as applicable to those parts that provide compressed publicize, modulate the brake pipe, and otherwise control the movement of the train. All remaining parts are subject to the inspection requirements of parts 215 and 232.

( vitamin d ) Where a dragoon ‘s collective bargaining agreement provides that a carman is to perform the inspections and tests required by this part, a carman alone will be considered a certified person. In these circumstances, the railroad shall ensure that the carman is properly trained and designated as a dependent person or certified mechanical examiner pursuant to the requirements of this separate .
( vitamin e ) A railroad track must notify the locomotive engineer that the class I brake test was satisfactorily performed, whether the equipment to be hauled in his train has been off-air for a period of more than 24 hours, 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 data required by this paragraph may be provided to the locomotive engineer by any means determined appropriate by the railway ; however, a written or electronic record of the information must be retained in the cab of the controlling locomotive until the train reaches its address. The written or electronic criminal record must contain the date, clock, total of freight cars inspected, and identify the qualify person ( second ) performing the test and the location where the class I brake trial was performed .
( fluorine ) Before adjusting piston travel or working on brake rig, cutout tittup in bracken pipe branch must be closed and vent reservoirs must be voided of all compressed air. When cutout cocks are provided in brake cylinder pipes, these cutout cocks lone may be closed and air reservoirs need not be voided of all compressed tune .
