What equipment is mounted to the roof of a Siemens trailer car?
2 HVACs
What are the different motor car types for a Siemens consist?
How are they identified?
DMA = PA circuit breaker
DMB = CCTV circuit breaker
What equipment is in the traction container?
What functions do they perform?
Traction inverter:
- converts 1500vDC to variable 3 phase AC for traction motors
Traction control unit:
- processes inputs from master controller and powers motors accordingly, controls holding brake
What is in the high voltage container?
Right hand side:
- HSCB, grounds switch (M car)
- auxiliary equipment (T car)
Left hand side:
- brake control unit
What does the static inverter do on a Siemens?
Converts 1500v DC to:
- 400v AC (3 phase)
- 230v AC (single phase)
- 110v DC (battery, safety loop)
What is the purpose of the self excite button?
Manually starts the SIV in the event of low battery supply
What are the positions of the master selector switch?
Reverse
Neutral (stopped at signal, cab unattended/deactivation)
Forward
Set speed (6km/h)
How is the cab made active in a Siemens?
- Key in master key switch
- turn key to “on” position
What are the operating zones on a Siemens master controller?
Emergency brake (B7)
Brake (B1-B6)
0 (coast)
Drive (D1-D7)
What are the brake cylinder pressures for each level of braking?
Holding brake = 110 kPa
B1 = 57 kPa
B2 = 83 kPa
B3 = 109 kPa
B4 = 136 kPa

Where is the trailer car fault and MCB panel located?
To the right of door 2
What are the positions of the brake pipe mode key switch?
0 - normal train operation
1 - pushed by other train
2 - pulling other train
3 - pulled by other train
4 - pushing other train
At what main res pressure will the emergency brake apply?
<600 kPa
