RULE 34. Air brake test information must be reported to the Umler file within 24 hoursof repair date by the repairing company when Single Car Air Brake Test hasbeen performed. Refer to AAR Office Manual Rule 93.5. Single Car Air Brake Testing must be performed at 90 psi.6. Any car requiring a Single Car Air Brake Test must be equipped with anapproved pressure measurement tap and use the Brake Cylinder LeakageTest Gauge Method. If a car is not equipped, install required tap(s) asfollows. Refer to AAR standard S-4020 for detailed information. The newlyapplied tap shall be mounted such that it is always pointed at or above thehorizontal position to prevent trapping moisture. This does not apply to tapsmounted on empty/load devices.a.For cars (or articulated units) with single capacity brake systems anda single reservoir (per unit), the preferred location of the brakecylinder pressure tap is within a two-foot radius around the exteriorsurfaces of the pipe bracket where possible. The tap must be locatedin the piping to the brake cylinder(s), in a blanking plate mounted onthe brake cylinder (on cars with single brake cylinders) or in a coverplate applied to an automatic test device access port. If there is a pipeplug already in place, remove the plug and apply the pressure tap.b.For cars with empty/load valves, the preferred location is within a twofoot radius around the exterior surfaces of the empty/load valve wherepossible. There must be one pressure tap applied for each empty/load device on the car. The tap must be located in the piping from theempty/load device to the brake cylinder(s), on a blanking platemounted on the brake cylinder (on cars with single brake cylinders) oron the empty/load device. If there is a pipe plug already in place, inthe proper location, remove the plug and apply the pressure tap.c.For cars with relay valves and multiple reservoirs, one brake cylinderpressure tap shall be applied in accordance with 3.B.6.a. or 3.B.6.b.and additional tap(s) shall be located between the relay valve(s) andthe brake cylinder(s) being controlled by the relay valve. If the relayvalve controls only one cylinder, a tap mounted in a blanking plate onthe cylinder may be used.7. When performing a Single Car Air Brake Test, reflective sheeting must beinspected and cleaned per Rule 66—Reflective Sheeting.8. When performing a Single Car Air Brake Test in shop or on repair track, carsequipped with F-Type trainline brackets (see Rule 17, Figure 17.2) using a7/8 inch pin retainer bolt shall have the bolt replaced with a pin assemblyaccording to Rule 17.B.12.— 16 —
RULE 39. A car on a shop or repair track shall be tested to determine that the airbrakes apply and remain applied until a release is initiated, and the pistontravel shall be inspected.a.The following steps are required:(1) Charge the car to 90 psi(2) Make a 30 psi brake pipe reduction(3) Reduction must not produce an emergency application(4) Confirm brake shoes are against all wheels(5) Inspect for nominal piston travel(6) Recharge brake pipe to 90 psi(7) Brakes must release10. For piston travel requiring adjustment, refer to the initial setup column inFigures 3.1 through 3.12 and to the appropriate standard, S-4009,“Compression Slack Adjusters—Inspection, Testing, Removal, andApplication,” or S-4010, “Tension Slack Adjusters—Inspection, Testing,Removal, and Application.” Adjustment of piston travel is a non-billableitem, except for Job Codes 1150 through 1152.11. When setting piston travel on cars equipped with empty/load devices,condition the empty/load equipment for a loaded brake setting. For detailedinstructions for setting equipment to loaded position, refer to MSRP S-486.12. During accelerated application, valve operation of the NYAB DB-20emergency portion, air may be observed escaping from the interface of theside cover and body. This is air which is being released to exhaust by theoperation of the accelerated application valve and does not constitute acondemnable leak (see Rule 4, Figures 4.12 and 4.13).13. During release valve operation, an intermittent escape of air may be notedaround the bottom cover of the release valve. During the initial stages of abrake application, an intermittent escape of air may be noted around thebottom cover of the service portion. This is air that is being released toexhaust by operation of the valve portion and does not constitute acondemnable leak (see Rule 4, Figures 4.12 and 4.13).14. New gaskets must be applied to both end air hoses whenever a car is on ashop or repair track for any reason.15. Operating components of movable end-of-car hose assemblies must beinspected for proper travel and restrictions per Rule 6. Any binding shouldbe corrected and repairs must conform to the original or approved modifiedconstruction of the car. Contact car owner with questions.16. When on shop or repair track, inspect and test hand brakes in accordancewith AAR Standard S-486 Hand Brake Inspection Requirements. Paint tohand brake chain as shown in Rule 13 is to be applied and maintained attime of single car air brake test. Hand brake chain must be painted andmaintained per Rule 13.17. When on a shop or repair track; beams, brake hangers, hanger pins andbrackets, bottom rod and brake beam safety supports should be inspectedand renewed or repaired per Rule 7.— 17 —
RULE 318. Slack adjusters repaired or renewed on other than repair track may betested without the use of a single car test device. 20 psi reductions must bemade from a brake pipe pressure of at least 80 psi. All other steps in MSRPS-486 paragraph 4.1 must be followed.19. Except for cars equipped with either a 10 inch or an 81/2 inch diameterbody-mounted brake cylinder, all cars must have legible decals, or stickersaffixed to the car or must be equipped with a badge plate displaying Initial setup information The permissible brake cylinder piston travel range for the car when performing the initial terminal (Class I) brake test and inspection The length at which the piston travel renders the brake ineffective, if different from the initial terminal brake test and inspection limits.a.Decals must meet the requirements of AAR Specification M-947 andmust be a minimum size of 7 inch by 8 inch. See Rule 80 forapplication and billing.20. When a car is inspected and tested per Chart A line 14 or a car is inspectedfor a LORF-AHS EHMS alert, considerable special attention must be givento the following items during car inspection, since they are known to be keycontributors to Undesired Emergency (UDE) events: Excessive wear, slack, or bending on A or B end uncoupling levers. Alsocheck toggle clearance where the cut levers and lock lift interact. Bent, broken, or defective end air hose arrangements. Reworked or fabricated arrangements may require additional focus. Pay special attentionto trolley arrangements for proper travel and binding or fouling, bent, orbroken conditions. A and B end hose support conditions and proper adjustment for height. A and B end angle cock conditions. Trainline conditions that may contribute to a stretch leak (broken bracketsand missing pipe clamps, for example) A and B end intermediate air hoses must be inspected thoroughly, especially for issues that would arise during transition of slack action, such asbinding through support mechanisms, pinching, and incorrect length.Inspect through range of travel.21. Per Chart A line 14, one additional Service Stability Test (S-486 3.8) andone additional Separate Vent Valve Test (S-486 3.4.3, if equipped) must beperformed if a car passes the SCABT without replacement of any of thefollowing: a service valve, emergency valve, A-1 reduction relay valve, ventvalve, B1 quick-service valve, or pipe bracket.— 18 —

Multi-unit cars have multiple brake sets—each set comprising a controlvalve and appurtenances. When one brake set is tested for cause (perChart A), each remaining brake set must receive a separate Single Car AirBrake Test. Report one test date to the Umler file. When a tap is added toone brake system, each remaining brake system must have tap applied andtested.5. All car owners must ensure that initial air brake testing information isreported to the Umler file in the form prescribed by the current AAR UmlerData Specification Manual.— 29 —
RULE 36. Problems reporting air brake test information to the Umler file should bedirected to: csc@railinc.com.7. Why Made Code 12 may not require a billable item.8. If evidence is available that a non-condemnable built up tread or slid flatwere caused by hand brakes having been left on, do not test the car.9. Report why made 24 when test described by Job Code 1144, 1145, or 1146is performed for noncondemnable built up tread or slid flat. Do not reportwhy mades 12, 20 or 21 for this cause for attention.10. If car is listed in Maintenance Advisory MA-63 or Early Warning EW-5171,“Cars Overdue for Periodic Air Brake Testing”, and Single Car Test isperformed, Job Code 1139, Job Code 1140, or Job Code 1142 should bereported and car must be removed from Maintenance Advisory MA-63 orEarly Warning EW-5171.11. If a car is tested for MA-63 or EW-5171 and has an open EHMS LORF-NCFalert, complete the LORF-NCF procedure per Rule 3.12. A LORF-NCF EHMS alert is activated when a car has a Unique CarGrouping Count (UCGC) of three or more. A UCGC is the number of uniquegroupings of cars surrounding and including the car in question when one ormore LORF-NCF events have occurred.13. When a car is inspected and tested per Chart A line 14,a.Report the SCABT associated with a LORF-NCF cause for attentionusing Why Made Code 1A when no other Why Made Code applies.b.The applicable LORF-NCF EHMS alert must be closed once theinspection and the SCABT are complete, within 24 hours.14. A LORF-AHS alert is activated when a car has experienced three unique airhose separations with any partnering car or two unique air hose separationswith different partnering cars.15. The applicable LORF-AHS EHMS alert must be closed using JobCode 1128 once the inspection is complete, within 24 hours.16. Defects related to piston travel that is outside of nominal range, asdescribed in A.1.d. and A.2.b., only require piston travel adjustment, not asingle car test, unless a single car test is otherwise required by CHART A.17. Additional charge per Rule 75 may be made if jacking of car is necessary tosafely accomplish repairs. The jacking procedure utilized to perform repairssafely will be determined by the repairing facility and/or repair force.Exception to choice of jacking procedure will not be allowed.18.
