NPR 726 Using half pilot staffs

Introduction

Half pilot staffs (half-staffs) authorise movements in only one direction. They are used for:

• pilot staff working of rail traffic over some signalled bidirectional sections of line, or
• protection of work on track.

Two half-staffs are joined together as a pilot staff to authorise bidirectional movements.

A half-staff is marked with:

• the name of one end of the section
• if necessary, the line or the location name
• sometimes, a location number or signal number.

Half-staffs are secured in pilot staff locks at the ends of sections:

• on a nominated signal, or
• on a post near a nominated signal, or
• in a cabinet near a signal.

Taking a half-staff from its lock prevents clearance of signals allowing entry to the affected section.

Authorising pilot staff working

Network Controller

1. Tell the relevant Signallers to arrange for removal of the half‑staffs at the entry and exit ends of the section.
2. Tell the exit-end Signaller to:
   1. secure the exit-end half-staff out of use
   2. tell you when this has been done
   3. tell the entry-end Signaller that the exit-end half-staff is secured out of use.
3. Get the necessary assurances for pilot staff working.
4. Compile an NRF 010 Pilot Staff Working Introduction form to authorise pilot staff working in a defined pilot staff section.
5. Issue the Pilot Staff Working Introduction to the Signallers at both ends of the pilot staff section.
6. Tell affected Signallers about the details and running‑direction of the first movement.
7. Tell the Signaller at the entry end to use the entry-end half‑staff to authorise movements.
8. Record, in permanent form, the time that pilot staff working started.

Getting a half-staff

Signaller at the entry end

1. Arrange for a Qualified Worker to remove the half-staff.

Qualified Worker

1. Go to the correct half-staff location.

1. Take the half-staff from the pilot staff lock.
2. Check that the half-staff is the correct one.
3. Check that affected signals at the location are at STOP.

Unidirectional pilot staff working

A half-staff can authorise one or more movements in one direction only.

Entry-end Signaller

   1. an NRF 008 Pilot Staff Notice (PSN) form. Record that the exit-end half-staff is secured out of use
   2. an NRF 011 Worksite Warning form, if there are more than six worksites in the affected portion.
2. Arrange to show the Pilot Staff Working Introduction and the half-staff to the Driver or Track Vehicle Operator of rail traffic ready to depart, and give the Driver or Track Vehicle Operator a completed:
   1. PSN
   2. NRF 007 Pilot Staff Ticket.
3. If the block is clear, authorise the Driver or Track Vehicle Operator to proceed.

Driver or Track Vehicle Operator

1. Check the assurances in the Pilot Staff Working Introduction form and the PSN.

3. Give the Pilot Staff Ticket to the exit-end Signaller.

Exit-end Signaller

1. Fulfil the Pilot Staff Ticket.
2. Report the arrival of rail traffic to the:
   1. entry-end Signaller
   2. Network Controller.

Joining half-staffs for bidirectional movements

To authorise bidirectional movements, the half-staff from one end is joined to the half-staff from the other end.

Network Controller

1. Tell the Signallers:

• which half-staff will be transferred
• whether to transfer the half-staff by rail or by other means
• to tell you when the half-staffs have been joined.

Signaller sending a half-staff

1. To transfer the half-staff by other than rail:
   1. check the section is not occupied
   2. arrange for the half-staff to be taken and given to the Signaller at the other end of the section.
2. To transfer the half-staff by rail:
   1. check that the block is not occupied
   2. compile a PSN
   3. record that the half-staff at the other end of the section is secured out of use
   4. show the Pilot Staff Working Introduction form to the Driver or Track Vehicle Operator of rail traffic ready to depart
   5. give the Driver or Track Vehicle Operator the PSN and the half-staff.
3. Authorise the Driver or Track Vehicle Operator to proceed.

Driver or Track Vehicle Operator

1. Check that the half-staff is the correct one for the section.
2. Transfer the half-staff, and give it to the exit-end Signaller.

Signaller receiving a transferred half-staff

1. Join the two half-staffs to make the pilot staff for the section.
2. Tell the Network Controller that this has been done.

Network Controller

1. Record, in permanent form, the time that the half‑staffs were joined.

Bidirectional pilot staff working

Entry-end Signaller

1. Compile:
   1. a PSN
   2. an NRF 011 Worksite Warning form, if there are more than two worksites in the affected portion.
2. If there is to be a following movement:
   1. give the PSN to the Driver or Track Vehicle Operator of rail traffic ready to depart
   2. show the pilot staff to the Driver or Track Vehicle Operator
   3. give the Driver or Track Vehicle Operator a completed Pilot Staff Ticket.
3. If the next movement will be from the opposite direction, give the PSN and the pilot staff to the Driver or Track Vehicle Operator of rail traffic ready to depart.
4. If the block is clear, authorise the Driver or Track Vehicle Operator to proceed.

Driver or Track Vehicle Operator

1. 5.   Check that the issued PSN and the pilot staff or Pilot Staff Ticket, are correct for the section.
2. 6.   Give the pilot staff, or the Pilot Staff Ticket, to the exit-end Signaller.

Exit-end Signaller
