Week 9 - SLW

Question 1

Over what type of line can you use SLW? (P1 Reg 1)

Answer 1

Double line

When one line of a double line becomes blocked, SLW by pilotman allows trains to travel over the other line in either direction

Question 2

Who is appointed to be in charge of SLW? (P1 Reg 4.2)

Answer 2

The pilotman

Question 3

Who will appoint the pilotman? (P1 Reg 2.1)

Answer 3

Network Rail Area Operations Manager

Question 4

What do you need to remind a pilotman of when making the arrangements for SLW? (P1 Reg 2.2.2)

Answer 4

• Controlled level crossings which are protected by signals
• Automatic level crossings
• Barrow or foot crossings with white light indications
• Unworked points
• Intermediate signal boxes which are closed and what time they will open
• Any ESR’s / TSR’s affecting either the single line or any train returning to the proper line
• If the obstructed line is

1) Protected by a line blockage as per TS1 Reg 13.2
2) Under T3 possession
3) Occupied by a failed train

Question 5

When can you divide the single line into two sections for wrong direction movements? (P1 Reg 3.6)

Answer 5

• The arrangement is authorised in the SBSI’s
• The arrangement is authorised by the NR Area Ops Manager
• An intermediate handsignaller is appointed as shown in the SBSI’s

Question 6

When does SLW come into effect? (P1 Reg 2.2.1)

Answer 6

When the RT3191 form is completed

Question 7

What is the restriction with SLW where the protection for a line blockage is in the same signal section as the crossover? When does this not apply? (P1 Reg 3.3)

Answer 7

• When the obstructed line is protected by a line blockage, SLW must not be introduced if the line blockage protection is in the same signal section as the crossover
• This does not apply if the line blockage is beyond the facing crossover that will be used for SLW

Question 8

When do you need to arrange for an LXA at an AHBC crossing within the SLW section? (TS9 Reg 3.2)

When do you need to arrange for an LXA at a CCTCV crossing within the SLW section? (TS9 Reg 6.9)

Answer 8

• When the AHBC crossing does not have wrong direction controls
• Always for a CCTV crossing, unless authorised in the SBSI’s

Question 9

When does a handsignaller not need to be appointed? (P1 Reg 3.5.3)

Answer 9

• A main aspect signal which applies to trains leaving the single line is provided at the crossover

or

• The pilotman travels with every train over the single line in the wrong direction

Question 10

During SLW the visibility is poor, when does a handsignaller not have to be provided? (P1 Reg 3.5.4)

Answer 10

When a main aspect signal which applies to trains leaving the single line is provided at the crossover

Question 11

During SLW when may a pilotman authorise a train to enter or foul the single line? (P1 Reg 5.1)

Answer 11

Only after getting the signaller’s permission

Question 12

How are trains signalled in the right direction during SLW? (P1 Reg 3.4)

Answer 12

Normally

Question 13

When controlling wrong direction movements through the SLW section who do you issue instructions to? What do you need to make sure that they understand? (P1 Reg 3.5.2)

Answer 13

• You issue instructions to the pilotman and to handsignallers
• You must tell the handsignaller if the instructions for the train movement has been given to the train driver
• You must make sure that the pilotman and handsignaller understand what to tell drivers and to work only to your instructions

Question 14

What is the speed limit for the first and subsequent trains travelling in the wrong direction when passing over power operated points that are facing the movement in a SLW section that have not been secured and padlocked? (P1 Reg 3.7.3 and P1 Reg 6.2.c)

Answer 14

• 15mph for all trains

Question 15

What is the speed limit for the first and subsequent trains travelling in the wrong direction when passing over power operated points that are facing the movement in a SLW section that have been secured and padlocked? (P1 Reg 3.7.3 and P1 Reg 6.2.c)

Answer 15

• 15mph for the first train

- 50mph for subsequent trains

Question 16

Who authorises the withdrawal of SLW? (P1 Reg 14.1)

Answer 16

Only the pilotman

Question 18

How far does the line need to be clear when allowing a train to enter the single line in the wrong direction if there is a main aspect signal to control the movement through the crossover at the end of the single line? (TS2 Reg 9.2.1)

Answer 18

When the line is clear up to and including the point 183m beyond that signal

Question 19

How far does the line need to be clear when allowing a train to enter the single line in the wrong direction if there is a a handsignaller opposite the signal protecting the crossover? (TS2 Reg 9.2.2)

Answer 19

When the line is clear up to and including the point 183m beyond the handsignaller

Question 20

How far does the line need to be clear when allowing a train to enter the single line in the wrong direction if there is no main aspect signal to control the movement through the crossover and no handsignaller present? (TS2 Reg 9.2.3)

Answer 20

Except during poor visibility:

• If the crossover is facing the movement, the crossover must be reversed and the line is clear up to and including the overlap of the next signal beyond
• If the crossover is trailing the movement, the crossover is correctly set and the line is clear to a point 400m beyond

(During poor visibility you require either a handsignaller or a main aspect to control the movement)

Question 21

What train movements can be started in SLW without the pilotman present? (P1 Reg 5.2)

Answer 21

• A movement to / from an unaffected route at a junction at the end of the single line
• To pass through a trailing crossover which is on the approach to the obstruction
• An assisting train may enter or foul the single line, as long as the pilotman has given permission

Question 22

What train movements can you authorise without the pilotman’s permission? (P1 Reg 5.2)

Answer 22

• A movement to / from an unaffected route at a junction at the end of the single line
• A movement to pass through a trailing crossover which is on the approach to the obstruction
