Multiple Signals, SPECIAL SPEEDS,Level XINGS Flashcards
How should multiple signals on the same post be read for 2 positions signals?
From Top to bottom left to right
Each signal has its own road (4 signals = 4 directions)
What is a co-acting signal? What’s the purpose?
They used were a signal, cannot be easily seen due to an obstruction
How can we identify which signal is the co actor?
It has the same number as the actual signal it may (or may not) be followed by the letter P
What speed is the definition of
extreme caution?
Not exceeding 25 km/h or posted track speed if that is less than.
Being able to stop the train in half the distance that can be seen and being prepared to find the section ahead, occupied, obstructed or track damaged
What circumstances are we required to do a max of 25 km/h?
• At Beginning of Terminal dead end platforms
When are we required to do 40?
-2 answers
• To and from mainlines diversion from the straight track
• Train assisted by another when brake is controlled from the lead
When are we required to do 15?
- Passing over, facing points, that are normally trailing points
- shunting movements
- Pushing trains during a rescue
- Moving in a siding
- Wrong line movement at a level Crossing
- Passing over facing points when held by hand
Are we required to follow speedboards?
Yes
Where are curve boards located?
(In regards to the line so you know which line it applies to)
On the left-hand side of the line, facing the driver, when approaching the curve from either end
When should the driver reduce the speed of the train when faced with a curve board?
Before the train into the curve, the train must be at or below speed indicated
not at the actual curve board
What is a WOLO (advice Notice) ?
It is a speed restriction that is applied due to the increased stress imposed by a higher temperature on the tracks
What is a WOLO 80?
80 km/h max speed
RAIL TEMP is 55 or above
(Line specific)
Before update Temperature forecast 38° - 41°
Rail temp 55° and rising
What is WOLO 70
Junction specific
Max speed 70 km/h
When RAIL temp is above 58
Previous to the update was when Temperature reached above 42°
How are drivers notified about Wolo restrictions?
Notis is placed in the Sign On area
Noticeboards at Flinders Street
TC calls throughout the day
WOLO boards at various locations
At what time WOLO restrictions usually enforced?
Between 12:00 and 20:00 hours
Who can cancel a WOLO?
Track Manager
What are the different types of level crossings?
Boom gate with flashing lights and warning bells
Pedestrian and bicycle with active control
Pedestrian and bicycle with passive control
Tramway level crossings
Warning, lights only
Private ‘giveaway to trains’ crossings
What does active control mean? What does passive control mean?
Active - Flashing lights bells and boom Gates
Passive - Fixed warning signs only
What is level crossing activation points?
At some locations level crossings are activated when the train passes an automatic signal through short-circuiting the track circuit or activating the axle counter
What is a flashing light repeating side light?
A repeating flashing red or white side light that the driver can see at a level crossing,
which tells the driver warning devices are active and functioning
Name three types of whistle boards
Normal type
healthy state indicator type
predictor board type
How much the driver respond on passing a normal type whistle board?
- Sound along whistle
- Observe the level crossing activates
- Observe crossing is clear of vehicles, pedestrians or other obstruction
- Sound along whistle prior to entering the Crossing
What is a healthy state indicator whistle board
A yellow cross - indicates the crossing is working correctly
What is a predictor board?
A black diagonal cross inside a black circle on a white background
On reaching predictor board drivers must not increase speed until train has entered the crossing
Currently none within metro system
When another train is approaching the Crossing at the same time as your train, what must both drivers do?
Both drivers must sound the whistle continuously until both trains have reached the crossing
What is the definition of a long whistle?
Distinct with
Intensity,
Duration or
Repetition
appropriate at which the warning is required to be heard
When starting a train from a platform near the Crossing with no boom gates how many times must driver sound the whistle?
2x
- When leaving the platform
- And again, when approaching the Crossing
What is the definition of emergency whistle?
A series of short urgent blasts on the train whistle
How should a driver respond on observing danger at a level crossing?
Apply the emergency brake
Sound a continuous, whistle
Report the incident to TC
(Or REC if other lines affected)
How must the driver respond if protection equipment has not operated when approaching the level crossing?
Attempt to stop the train, using emergency break if necessary
Sound an emergency whistle
Report to TC / REC call if required
If the train stops prior to the level crossing when driver has noticed, protection devices have not operated what must a driver do next?
- Sound a whistle
- Move train forward cautiously to within 3 m of the crossing to activate the circuit
- Stop the train once boom gates activate
THEN if safe to do so
- Ensure saloon lights are operational
- Sound a continuous whistle until the leading cab is clear of the crossing
- Proceed at a max of 15 km/h
- once lead cab is clear of xing, proceed as normal
If a train cannot stop prior to the level crossing the driver, must do what?
•. Continue to sound an emergency whistle
•. Flash headlights between high and low beam
•. Use any means to warn vehicles and pedestrians
•. Contact TC immediately
Can a driver proceed over level crossing, when the Crossing equipment is inoperative, even with authorization given to pass a defective signal by the signaller?
NO
if boom gates or crossing protection is inoperative at no time must a driver pass the crossing
How must a driver proceed when returning to the rear (or traveling on the wrong line) through a level crossing?
• Stop short of the level Crossing
• Move the train cautiously forward until the level crossing equipment starts to operate
• Stop the train
• Proceed through the crossing, once all protection equipment has fully operated and clear of vehicles and pedestrians
What is the max speed when the train is making a wrong line move through a level crossing?
15
Can a driver Enter a level crossing, without a Competent worker activating the crossing, during single line working?
No
Once the level crossing is activated during single line working, what must a competent worker do to let the driver know it is safe to proceed through the crossing ?
Gives the all right hand signal
What key switches can manually place the signal to the STOP position and what is the purpose of this?
5P & Abloy key (for high speed points)
Purpose of this is to raise the level crossing boom gates To allow the traffic through when they were unavoidable extended delays
When is the only time the level crossing key switches are operational?
The key switch will only work when the home signal there is in fleeting mode (Switched out)
In what position is the key switch for a home signal when the signal is at proceed?
REVERSE
Must turn key to NORMAL to raise boomgates
(signal goes to stop)
In what position is the Key switch for an automatic signal when the signal is at proceed?
Normal
Must turn switch to reverse for boom gates to be raised (signal goes to stop)
What are common markings on the level crossing key switches?
The markings vary:
• N (normal) or PROCEED (vertical)
• R (Reverse) or Stop or Boom Disable (2 or 10 o’clock pos.)
In which position can a level crossing Key be removed from the key switch?
When it is in the vertical position
(Drivers advised to remove key from the drivers keys prior to operation)
How long might it take for the boom case to operate once the key is removed from the level crossing key switch?
3 mins
Where are the key switches for operating boom gates normally located?
Usually at the end of the platform or on the station building
Can be found on signaling diagrams
What is the purpose of tramway speed signs?
To advise drivers of the designated speed for that tramway crossing
What does a tram square sign look like?
Square yellow reflectorized sign, with black lettering
How far ahead is an advance, tramway square AHEAD warning sign provided from the actual tram square
200m from the xing
When must the designated speed on a tram square ahead sign, be reduced by?
Prior to arriving at the speed restriction sign at the level Crossing
Where is a tram squared sign located?
At the Tram Square at the commencement of the speed restriction
When does the tram square speed restriction end?
When the train reaches the END TRAM SQUARE clearance sign
How far from the level crossing is the
‘end tram square 3 car only’
clearance sign located FOR A 3 CAR TRAIN?
80 m from the level crossing to indicate when the rear of the three car train has cleared the tramway square
When can a driver resume track speed after passing an end trance Square sign?
(Is it when the drivers cab has past the sign, or when the whole train his past the sign)
Once the driver’s cab has passed the sign
How far is the
‘end tram square’
sign located from the Tram Square. And to which train does this sign apply?
160 m from the tram square
Once drivers cab has passed the sign, the 6 car train has cleared the tramway square.
What is this marker And what does it indicate?
Limited clearance marker
Indicates
Not much room from the train to the structure
