Siemens Cab equipment/Train overview Flashcards
What is the holding brake pressure?
110KPA
What is the speed threshold for the holding brake on a Siemens?
0.2km
At what speed can’t you apply your spring park brakes?
5km/h
What happens if you apply your spring park brake at that speed and over?
Safety loop de energises, emergency brake goes on
What is the brake pressure for B1?
57KPA
What is the Brake pressure for B6?
189kpa
At what pressure increments does the pressure go up from B1 to B6
26kpa to 27kpa B1-57KPA B2-83KPA = 26KPA B3-109KPA = 26KPA B4 - 136KPA = 27KPA B5 - 162KPA = 26KPA B6 - 189KP = 27KPA
What is emergency brake cylinder pressure?
280KPA
What is the job of a static inverter?
To convert 1500vdc from the pantographs and traction storage into 400vac
Where are the static inverters located?
Trailer cars
How many static inverters per car?
2
What happens if 1 static inverters” becomes defective and inoperative?
HVAC runs at 50% capacity
What happens if both static inverters become defective and inoperative?
Train fails to power
If the safety loop is bypassed, what emergency button is working?
Lead car only
What is the dead mans switch?
Test function for the hand and foot pilot valve
How long is the dead mans switch active?
60 seconds
When is set speed used?
For coupling and low speed shunting movements
What is the set speed limited too?
6km/h and an over speed light comes on
8km/h an emergency brake comes on
What happens when you travel over 119km/h?
Traction is lost and the train cannot accelerate
What happens if you travel over 120km/h
Over speed light illuminated
What happens if you go above 125km/h?
Emergency brake applies
What is a critical defect verbatim?
Critical defects are safety critical failures of the pneumatic friction brake system or a complete loss of Auxillary power (two defective static inverters)
Where is the first aid kit located?
Cabinet top right near b side wall
Where are the ATWs?
Beneath the cabinet
Where are the emergency track circuit jumper cables?
In a shelf above the cabinet
Where are the red and green flags?
To the left of the cabinet in their own recepticals?
Where is the fire extinguisher?
A side under the desk
Where is the switch stick
Beneath the cabinet
If you drop the foot or hand pilot valve, what happens?
Audible tone for 3 seconds then after a further 3 seconds the safety loop opens (emergency brake)
What happens if the cab/train manned circuit breaker is tripped?
Active cab will become non active and safety loop opens
Driving is only possible from another cab
Where is the Trailer MCB panel located?
To the side of door two at 2 end of the car
What does brakes cut out bogie 2 fault light mean in a trailer car fault panel?
Friction brake of bogie 2 has become isolated
How is a Siemens cars arranged?
DMA - T - DMB
How do you identify a DMA?
It has a PA circuit breaker
How do you identify a DMB
It is equips with a CCTV recorder circuit breaker
How do you identify what end you are on from the outside?
Air compressor indicates A side, 1 end
Battery box indicates B side 2 end
How do you identify what end you are in from the inside of a trailer car?
T car fault panel on the ceiling to the right of door 2 at 2 end
Name the roof mounted equipment
Pantograph
Antenna
Surge arrester
HVAC
What main res pressure does the safety loop open?
600KPA
How do you make a cab to saloon call?
Press cab to saloon Press button on much Relay your message Hang up mic Press cab to saloon
What does brakes cut out bogie 2 fault light mean in a the motor car fault panel?
Bogie has been isolated
