Day 3

Question 1

Name up to 8 sections of overhead wires?

Answer 1

*Hanger
*Dropper
*Insulated Dropper
*Catenary Wire
*Catenary Span Wire
*Spreader Bar
*Contact Wire
*Contact Span Wire
*In-Span Feeder

Question 2

What is ORCS?

Answer 2

Overhead Rigid Conduction System

A solid beam replacing overhead wires. Used in tunnels, and close to tunnel entrances.

Question 3

What are Beacons?

Answer 3

Beacons are train localisation equipment mounted on sleepers along tue network. They communicate with the train via the beacon antennas as trains pass over them.

Question 4

What are the different types of Beacons?

Answer 4

*Calibration of odometers
*ATO first approach (makes train aware of approaching station or limit of authority)
*ATO second approach (make train aware they have entered station or close to limit of authority)
*Localisation and relocalisation

Question 5

What are Axle Counters?

Answer 5

Axle counters are utilised as Secondary Detection Device (SDD) for rail traffic on network.

Used as a backup to the CBTC moving block system

Question 6

What is PPI

Answer 6

Point Position Indicator

Fixed signals in our network that provides information about the route, and indicating when a signal is clear for train to proceed or hold position.

Question 7

What are Buffer Stop Signals

Answer 7

Positioned at the end of a rail line/siding to indicate the end of the rail line.

Question 8

What are the two point components pictured called?

Answer 8

Question 9

What are the other point components pictured called?

Answer 9

Question 10

What is a ‘Facing Point’

Answer 10

Location at which a diverging movement may be made in the normal direction of travel

Question 11

What is a ‘Trailing Point’

Answer 11

Location at which a converging movement can be made in the normal direction of travel

Question 12

What is a Fouling Point

Answer 12

Located near the convergence of two tracks. The point marks where trains must be placed to prevent striking trains on the adjacent track.

Question 13

What are Catch Points?

Answer 13

Catch points physically prevent trains entering onto a mainline without authorisation.

In the normal position (not-authorised) there will be a gap between the switch blade and the stock rail, preventing the train from
Proceeding pass that point.

In reverse position (autherised) the switch blade will be hard up against the stock rail, allowing the train to pass.

Question 14

What is a Point Failure?

Answer 14

When points lose detection and show an unknown status, the signalling system conditions to set the route are not met. This causes the protecting signal (PPI) to display a “STOP” aspect and any established CBTC routes to be cancelled.

Question 15

When operating Metro trains, what are the CJCT responsibilities regarding points?

Answer 15

• When operating manually in PM or RM mode, it is the responsibility of the CJCT to check the points are set correctly by visually checking the points position and corresponding PPI
• In low visability use headlights and request TC to raise tunnel lighting to check points correctly
• If the CJCT cannot confirm the correct position of the points for the train movement, they must STOP and not move the train.
• At times a CJCT may need to preform a visual inspection on the points bf exiting the train and going trackside.

Question 16

What are the Modes of Operation

Answer 16

• UTO -Unattended Train Operations
• PM - Protected Manual Mode
• RM - Restriced Mode (RMF OR RMR)
• RRM - Remote Manual Mode

Question 17

What is UTO?

Answer 17

Unattended Train Operations

(normal mode) Driverless mode of operation, where trains are automatically controlled by ATC with full ATP.

Trains operate within CBTC and capable of operating in UTO at all times, except for some degraded operation scenarios and emergency incidents.

Question 18

How is UTO mode engaged?

Answer 18

• TC/DC has autherised for train for train to be placed into UTO
• Master controller in Full-Service Brake position
• Mode selector in ‘SHUTDOWN’ position.
• Turn train key to ‘LOCKED’ position and remove key
• Push and hold (2-3 secs) UTO engagement button. TCMS screen should go black, operator then taps screen to ensure train is in UTO
• Confirm train is on UTO with TC/DC

Question 19

What is PM?

Answer 19

Protected Manual

Utilised when ATO is not operational or for training reasons.

Train follows target speed restrictions with full ATP (automatic train protection)

Train operator controls the propulsion, coasting, braking and manually controls the opening and closing of train doors.

Automatic updating of journey info is
Displayed on PID’s and DRM’s.

Question 20

What is RM?

Answer 20

Restricted Mode

Either FORWARD or Reverse RM modes may be selected.

Allows operator to manually control train movement, with ATP limiting speed to 25kph, applying EB if speed surpassed.

When operating in RM mode, train may pass a Signal at Danger (STOP) and enter a ZIKS, SPKS, CSKS protected part of the track,

RM may also be used in conjunction with the ATC Bypass switch. In this mode, the train is not supervised or protected by the signalling system. Maximum speed is an enforced 25kph (train will cut acceleration at top speed, no EB will engage)

Question 21

What is RRM?

Answer 21

Remote Restricted Manual

In cases where a train has delocalised, RRM mode allows remote movement of 200m to move train to nearest beacon to localize. Speed is restricted to 25kph

RRM mode allows a maximum of 2 200m movements. An operator using RM mode will than be required to move the train

Question 22

What is DSD?

Answer 22

Driver Safety Device
(dead man switch)

Question 23

What is the panel pictured?

Name each part.
