1
Q

Faults that may prevent the Pantograph from rising?

A
  1. Auxiliary Compressor Governor defective.
  2. Auxiliary Compressor defective.
  3. Auxiliaries Set Button not pressed.
  4. Master Switch in Off.
  5. Low Battery Voltage.
  6. Air leak on Pantograph System.
  7. Battery fuse blown.
  8. Batteries dead.
  9. Pantograph isolated.
  10. Control Positive / Auxiliary Compressor / Battery Positive MCBs tripped in PTS Train Supply Panel.
  11. Control Positive MCB tripped in cab.

If unable to get enough air to raise the pantograph, it is possible to couple to another unit to feed air through. Before coupling, trip the Auxiliary Compressor MCB in the PTS Train Supply Panel of the defective unit to cut out the non-return valve allowing air to flow through to the pan air system.

Q

What will cause an ‘Emergency Brake Application’.

Break Continuity Wire - Breaking Wire 13

A

Powered by batteries - supplies Brake Controller in live cab.
Runs whole length of train.
If circuit is not energised - Brakes cannot be released

Below is a list of systems and equipment that can de-energise circuit and cause Emergency Brake Application.

Signalling Fail Safe:

TPWS - if activated by train stop, over speed or buffer stop loops
AWS – failure to cancel horn within 4 seconds

Passenger Fail Safe:

Pass com operation – in any Vehicle (including driving vestibule)
Egress operation – door opened while train is moving above 6mph

Driver Fail Safe:

  1. More than 1 driving desk open
  2. Master Switch - moved to neutral above 6mph
  3. Brake Controller – in emergency in any cab
  4. DSD – released when master switch in Forward or Reverse

Air Fail Safe:

  1. Brake Reservoir Governor – on each Vehicle, below 5.2 bar or defective
  2. Low Main Air Governor – on each DMS, below 5.2 bar or defective

External Train Equipment:

  1. Drum switches - On leading/trailing cabs incorrectly positioned

Electrical Fail Safe:

  1. Auxiliaries – tripped out
  2. Battery Positive MCB – in PTS Vehicle, tripped out
  3. Brake Control MCB – in DMS cab, tripped out in front or rear cab - (if tripped in rear cab brakes will release when at a stand but no traction power available)
  4. Control Positive MCB – in any cab or TS tripped out
  5. Control Supply MCB – in PTS Vehicle, tripped out
