Final Study Flashcards
Definition of 908 Blocking
“Blocking” means holding signals at stop or points set to prevent rail movements from entering a section of line. Controls to points and signals are tagged / blocked / collared, to prevent the signals from being cleared and points moved.
What are the three forms of 908 blocking occupations?
- Proceed. 2. Work at. 3. Work between.
What is the definition of a Proceed track occupation?
Movement must only proceed in the direction specified. Hi-Rail Vehicles and Trolleys may set back short distances of up 100 metres within the limits of the proceed authority provided the movement is able to stop within half the clear visible distance and clear of any obstruction.
What is the definition of a Work Between track occupation?
Movement may work in either direction between the locations specified. The movement must not enter a station or siding which is a limit of the authority unless authorised to do so.
What is the definition of a Work At track occupation?
The authority is provided for work happening at one location only.
What are the three steps for applying 908 blocking?
- Enquiry from the person wanting to work on track. 2. Pre-authorisation check from Train Control. 3. Authorisation process: Train Control - Addresse - Train Control
What is required in a rule 908 enquiry? (7)
ITOLOTN 1. Identity. 2. Type of protection requested (proceed, work between etc). 3. On tracking location. 4. In multi-line areas, the line being occupied. 5. Occupation area including off tracking location. 6. Time required for work. 7. Nature of the work.
What information included in a 908 track call? (7)
- Addressee. 2. At location. 3. Commencement time and clearance time. 4. In multi-line areas, the line being occupied. 5. Proceed / Work at / Work between locations. 6. Last train clear. 7. Section of track verified blocked.
What are the pre-authorisation checks for 908 blocking. (5)
- Ensure the occupancy will not conflict with rail movements. 2. Confirm the location of conflicting rail movements. 3. Confirm last train clear of on tracking location. 4. Record details on the graph. 5. Apply blocking to signals and points.
What is the sequence for issuing a Mis60? (7)
- Establish the purpose and limits of the Mis60. 2. Carry out safety checks. 3. Draw the area on the TC diagram in blue pen. 4. Prepare the Mis60. 5. Ensure the appropriate protection has been applied. 6. Transmit the Mis60 to the signaler and obtain a correct readback. 7. Transmit the Mis60 to the addressee and obtain a correct readback.
What is the process for cancelling a Mis60? (5)
- Addressee reports limits cleared. 2. Train Control acknowledge and completes the bottom of the Mis60 form (addressee also does this.) 3. Addressee says “that is correct” then destroys Mis60. 4. Other addressees advised by TC that the Mis60 is cancelled and the appropriate portion of the form completed. 5. Used Mis60s are archived in Train Control.
What are the safety checks prior to issuing a Mis60? (6)
- Identify identity and location to ensure the Mis60 is going to the correct person. 2. Establish whether a Mis60 is still in force in any part of the proposed area. 3. Plot the Mis60 on the TC diagram and check against previous Mis60s for conflict. 4. Draw the limits in blue pen as a block encompassing stations and time as per the Mis60. 5. Draw the number of the Mis60 in a blue circle towards the terminating end of the Mis60 line. 6. Any error must be crossed out and redrawn, not erased.
What process is used to re-issue / amend a Mis60? (4)
- Confirm the line is safe and clear if the area is to be changed. 2. Re-issue the Mis60 covering the changed area/hours with the previous permit cancelled in the special conditions portion of the new form. 3. Cancel the previous Mis60 by entering the cancellation time as the time the new permit was issued. 4. Advise all addressees accordingly.
What are the names of the CSP boards and where are they located?
- Advanced Warning board 2000m from work site. 2. Inner warning board 1000m from work site. 3. Compulsory Stop Board 500m from work site. 4. Work site begins/ends board at the start of the work site.
What are the RPO’s Train Controller’s responsibilities if a compulsory stop board is located at a signal.
- RPO arranges for signals to be held at stop to prevent confusion. 2. Signaller (TC) to apply blocking to the signals being held at stop until advised by the RPO that the line is clear and safe for traffic to proceed.

What is 905 CSP used for?
- Work that involves breaking the track.
- Work that will interfere with the safe operation of trains. E.g., - Welding - Rerailing - Maintenance with heavy tools and/or equipment
What protection may be used for placing CSP boards?
- ITD 2. Blocking 3. Foul Time 4. Track Warrant
What 3 safeguards should be applied when MTMVs are berthed / stabled / working within station limits or in a siding?
- Setting a diverging route 2. Erecting danger stop disc / light and derailing block. 3. Blocking (where available)
What rules apply to HRVs carrying out rail greasing?
- Only approve track occupations of sections that are completely clear of rail movements (no “follow” approvals). 2. Only a train should follow a grease truck unless TC has been advised the grease truck deliberately did not grease the planned work area or the HiRail vehicle is necessary for an inspection for safety purposes.
When may ITD be used?
- Moving on foot (inspections, investigations, site familiarisations) 2. Making minor corrections that will not interfere with the safe running of trains. 3. When crossing the line at a maintenance crossing.
What is ITD?
Individual Train Detection is the minimum qualification required to move and work unsupervised on the rail corridor.

How is “Low Speed” displayed? What does it mean?
Not to exceed 25 km/h, able to stop clear of any obstruction. Indicates the points are correctly set but not necessarily that the track is unoccupied.
How is “Medium Speed” displayed? What does it mean?
Not to exceed 25 km/h unless a speed board authorises a higher speed. Medium speed must be maintained until clear of all points to which the signal applies.
How is “Restricted Speed” displayed? What does it mean?
Not to exceed 40 km/h. Able to stop within half the distance of clear line visible ahead.
How is “Intermediate Speed” displayed? What does it mean?
Not exceed 50 km/h. Maintain Intermediate Speed until clear of all points to which the signal applies.
Define a fixed signal
A coloured light signal, it includes station entry and block entry boards.
What does a two position signal indicate?
The route set but not the permissible speed.
Define an imperfectly displayed signal.
A signal displaying an aspect not described in the rules or an unauthorised aspect. Also the absence of a signal where one is usually displayed.
What are the three reasons you would use an “R” light?
- Reset an axle counter
- Recover a disabled train
- For stacking trains if the frequency required it.
What three things do you need to ensure before using an “R” light?
- Points are correctly set.
- Following a movement in the same direction.
- Opposing signal is not cleared.
What is “Normal Speed”?
Not to exceed the maximum speed laid down for the locality or as limited by the class of train.
What is a controlled signal?
A signal controlled by a signaler / Train Control.
