BRAKE POWER CERTIFICATE:-

  BPC is issued after intensive examination of train in empty   condition.

• No sick wagon is allowed to run.
• Prepare in triplicate.
• Indicates brake power percentage of the train.
• BPC will be invalid if,

(a)  The destination of the train is not mentioned on BPC.

(b)  The train composition of train is changed by 10 four wheeler unit or more.

(c)  The train is stable more than 24 hours at train examination points.

(d)  The integrity is changed of CC rake more than four, 8 wheeled wagon.

AIR PRESSURE CONTINUITY TEST:-

OBJECTIVE:-

      1-Continuity of brake pipe pressure from engine to brake van/ last vehicle.

2-On reduction of brake pipe pressure by driver, train brake must apply.

3-In emergency condition, if guard destroys BP pressure, then also train brake should be applied.

WHERE TO PERFORM:-

1-    When an engine is attached ahead or behind the train engine.

2-    When an engine is attached behind the last vehicle of the train.

3-    When traction or engine is changed.

4-    When shunting is performed in a train.

5-    Whenever air pressure leakage/brake power work is attended on a train.

6-    When a stable load has to be cleared from a road side station.

PROCEDURE:-

1. Charge the train with air pressure and ensure the requisite amount

                In Engine                         In Brake Van

          BP- 5.0                                   4.8 Kg/cm211- Maintenance is less.

          FP- 6.0                                    5.8 Kg/cm2

2. Guard will destroy the BP pressure by 1 Kg/cm2 with the help emergency handle of brake van or angle cock of last vehicle.

3. Driver will ensure that BP pressure drops in engine also. He will observe Air flow indicator, light and buzzer.

4. Guard will place the emergency handle in normal position and will allow   the BP pressure to charge again.

5. Driver and Guard will ensure that requisite amount of BP pressure is charged again in engine as well as in brake van.

6. Driver will destroy the BP pressure to zero with the help of driver’s brake valve.

7. Guard will ensure the Bp pressure in brake van /last vehicle has also   dropped to zero.

8. To ensure brake application on train, Assistant Driver and Guard will check 3 or 4 wagons / vehicles from their respective ends.

9. Driver will charge again Bp pressure by keeping the Driver’s brake valve in release position.

10. Driver and Guard will ensure that BP pressure both in engine and brake van / last vehicle is charged again to prescribed amount slowly and at Uniform rate.
