11.2 The enhanced air brake test, No.1 brake test and No.1A brake test shall be performed on every train as specified in these Rules and company procedures/work instructions by:
- the brake pipe leakage method; or
- the air flow method.
11.3 The conductor, or in his or her absence, the locomotive engineer, shall be responsible for determining that the prescribed test(s) has been completed prior to departure. When a pull-by inspection for the brake release is performed on freight trains, the conductor or locomotive engineer shall be provided with the results of the release and in turn, will update the train brake status system.
11.4 A vehicle assisted No.1 brake test or enhanced air brake test, may be performed by a certified car inspector(s) in accordance with company procedures/work instructions, and shall be made available to a railway safety inspector upon request.
12. No. 1 Brake Test

12.3 Exceptions: A No.1 brake test is not required on:
- trains operating over main tracks, between yards, up to a maximum of a thirty (30) mile (fifty (50) kilometre) radius. Such trains shall be engaged exclusively in the setting off or lifting of equipment at industry(s), and/or the transfer of equipment between yards, and they shall be filed with the Department.

- that the condition of the brake rigging on each car in the train meets the minimum requirement specified in Sections 22, 23 and 24 of these Rules;
- that, once the proper signal has been given to apply or release the brakes, the application and release of the brakes on each car is performed by visible verification of the piston or brake indicator device displacement following a minimum 20 PSI (137 KPA) brake pipe service reduction, which must remain applied until a release of the air brakes is initiated by the controlling locomotive or yard test device; and
- that piston travel on each car is within the specified limits.
12.5 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 positioned at one end of the car(s) being retested, and the brakes must remain applied until a release is initiated after a period which is no less than three minutes.
12.6 A pull-by inspection by a certified car inspector may be performed to verify the release of the train brakes.
12.7 Certified car inspectors shall report, in accordance with company procedures/work instructions, the results of all brake tests performed. Any brake system defect(s) discovered during the brake test and not repaired prior to departure shall be documented as bad order and reported to the conductor, or in his or her absence, the locomotive engineer. The conductor/engineer shall update the train brake status system with the identified defect(s). The results of the tests performed by certified car inspectors shall be retained for ninety-two (92) days.
12.8 Except as provided in sections 8.1 and 8.5, after completing a No.1 brake test, a brake effectiveness test, or an enhanced air brake test, a train may only depart from the safety inspection location for that train with one hundred (100) percent of the train brakes operative.

- the brake pipe has been re-coupled after being uncoupled; and/or
- the locomotive is re-coupled to the train after setting off cars.
15.2 The continuity test shall verify the capability to transmit a signal between the leading locomotive and to the rear of the last piece of equipment on the train.
15.3 A continuity test need not be performed when the locomotive engineer has been changed, provided that all of the following provisions are met:
- must be a direct handoff at the crew change location (crew to crew at controlling locomotive). Does not apply to trains left unattended while waiting for the outgoing crew.
- train must not perform any lifts or set-offs at the crew change location. In such case, continuity must be established, unless the lift or setoff has occurred and continuity has been established prior to a direct handoff.

16. Train Information Braking System (TIBS) Test
16.1 A TIBS test shall verify that an emergency brake application, initiated from the controlling locomotive or dedicated Input and Display Unit (IDU) through the TIBS system, will cause an emergency brake application on the last piece of equipment on the train.
16.2 When the sense and braking component of the TIBS system is first added to a train or when it is suspected that the sense braking component has been stricken or damaged while en route the operation of TIBS will be verified by a qualified person(s) in accordance with company procedures/work instructions.
16.3 In the event of a TIBS failure, where the standard locomotive gauges and air flow indicator display no loss of air pressure, the train may proceed at a speed not to exceed twenty-five (25) mph (forty (40) km/h), until the TIBS resumes normal operation.
17. Transfer Brake Test
17.1 Prior to departure, the locomotive engineer, or the portable locomotive remote control device operator must verify that there is sufficient braking effort to control the transfer. Transfers must have air applied throughout the entire equipment consist and the last three cars must be verified to have operative brakes.
18. Push-Pull Operation
18.1 On a train operated in a push-pull mode, a continuity test must be made from the controlling cab car or locomotive after changing ends.
19. Portable Locomotive Remote Control Device Tilt Test
19.1 A portable locomotive remote control device tilt test shall be performed once every twenty-four (24) hours, and when it is not a direct operator to operator hand off. The test shall be performed in accordance with company procedures/work instructions, and shall verify:
- application and release of the train brakes;
- that an emergency brake application is initiated as per its design;
- when tilted, the device will apply the brakes and nullify the transmission of power to the locomotive traction motors.
19.2 A modified tilt test may only be performed on a direct operator to operator hand off, in accordance with company procedures/work instructions.
20. Trains Using Back-up Hose or Valve
20.1 Before starting a train from any point where the brakes are to be controlled by the use of a back-up hose or valve at the rear of the train, the brakes shall be applied by using the back-up hose or valve.
