What are the six operating positions of the 26L automatic brake valve on the N class? R M F S H E |
1. release - 500kPa in BP normal running position - not braking 2. minimum reduction - reduces BP by 50kPa to slightly apply brakes = smoother application of brakes-BP=450kPa 3. full service - service application zone - normal application of train brakes - self lapping. BP is 350kPa (or 325kPa). Auxiliary res & brake cylinder are fully equalised. 4. suppression - not really used - Vigilance Control suppressed-does not operate. 5. handle off - handle is removed in this position - used for trailing loco OR for your rear cab - VC disabled 6. emergency - applies train brakes faster-emergency. BP reduced to 0 kPa. Train must be brought to a stop before resuming running. |

What is the SA26 independent brake valve on the N class? R F |
Only brakes the loco. Use when stationary/slow movements/light engine. For stopping a moving train, use the automatic brake. Two operating positions: - release - brake cylinders have 0kPa - handle off in release position - full application - 310kPa |
|
What is the MU2A valve used for? |
The MU2A valve is used to isolate the independent brake valve when it’s not in use. It has two operating positions: - lead or dead - cut in - brake on - TRAIL 6-26 - cut out - brake off |

|
What is the No3 control pipe used for? |
The No3 control pipe connects the independent brake valve to to the brake racks on all locomotives in a multi-unit consist. |
|
|
What is the No4 independent release pipe used for? |
The brakes on all locomotives in the multi-unit consist may be released while the automatic (train) brake is applied by depressing the independent brake valve handle in the release position. |
