Q

What is a consideration of an IC regarding Diesel trains after power has been isolated to the track?

Q

What does run at caution mean?

A

That the train driver must travel at a speed whereby they can safely stop if necessary. On long straight stretches of line with clear visibility they can run at max 50mph but on bends or bad visibility it could be as low as 5mph.

16
Q

If crews committed to hazard zone without all control measures in place what needs to be done?

A

Priority message to control including:

  • location and nature of incident.
  • if trains need to be stopped or run at caution.
  • it traction current needs to be isolated.
  • action taken.
17
Q

Additional control measures needed of crews committed before all safety measures in place:

A
  • Brigade lookouts wither side of incident. Line of sight of poss.
  • Evac routes established and crews briefed. 3m from risk area and under supervision of safety officer.
  • min personnel.
  • do not enter tunnels unless confirmed trains have stopped.
  • crews to be withdrawn immediately on completion and control informed.
18
Q

Should LFB personnel be used as lookouts?

A

Generally no as network rail have trained staff for this due to the complexity of the network. However, in emergency circumstances they can be deployed for this reason.

19
Q

If LFB personnel deployed as lookouts what rules must they adhere to?

A
  • Handheld radio/Comms at all times with safety officer in hazard zone.
  • Acme thunderer. Portable lighting at night.
  • position agreed and not repositioned.
  • be aware of automatic trains.
  • 3m from track and facing approaching train.
  • high vis.
  • warn of approaching trains.
20
Q

How do you warn approaching train drivers that personally are on the line?

A

In daylight but holding both arms straight above your head and at night by waving a bright light violently from side to side.

21
Q

How do you request traction current to be isolated?

A

Priority message to control.

22
Q

What Comms facilities are available at railway incidents?

A
  • Channel 5 leaky feeder system on underground.
  • Signal post telephones on network rail.
  • gantry telephoned for OLE.
  • headwall telephones LUL.
  • public address systems.
23
Q

If following a Comms check at a 72d it is noted that channel 5 isn’t functioning correctly what needs to be done?

A
  • Inform station management.
  • Amend the status sign in LFB plans box.
  • Inform Control on return to station who wil report this to procurement.

Once defect rectified a retest is taken to and control notified of result.

24
Q

How can you identify an intervention point?

A
  • Access doors with black letters IP on white background.
  • Signs at platform level and in tunnels.
  • Priority message to control.

Keys are located in LFB plans box of adjacent stations.

25
Q

How do you get traction current switched off at a LU station and what needs to be done after confirmation?

A

Liase with responsible LU staff member. Once confirmed then message must be sent to control.

If no staff present then request must be made via control with exact location and reason.

26
Q

Can you go onto the track at an LU station without power confirmed off?

A

No.

27
Q

What should be contained in an LU LFB plans box and how can they be opened?

A
  • 2 sets of station plans (1 for command and 1 for BA).
  • Comms status indicator.
  • where necessary IP keys.

FB14

28
Q

How do the JLE (jubilee line extension) stations differ for firefighting purposes?

A
  • Station Control rooms with protected access.
  • Platform edge doors.
  • Ventilation systems (tunnels and station)
  • power supply points on stations and in tunnels.
  • pressurised staircase (IPs too) and FF lift.
  • Emergency service walkways and extra Comms systems.
29
Q

What is unique about DLR trains?

What is their max speed?

A

They are driverless. However, a member of staff on each train in contact with control centre who can manually drive if required.

55mph.

30
Q

Safe working distance on DLR?

A

2m from running rails.

31
Q

What is the acknowledgment signal a FF gives on a DLR to allow the train to pass safely?

A

1 arm raised facing oncoming train.

32
Q

What can impede jacking operations on a DLR train an how can you alleviate this?

A

Trains conducting shows which sit under the conducting rail.

Crews can release air by operating the valve situated inside the vehicle beneath the driving position at each end of the car. Shoe will be sprung down clear of the rail.

33
Q

Where can jacking be done on a DLR train and what type of jack?

A

On approved points. Body of train with 20 tonne hydrolite jack carried on FRUs and bogie of train with 10 or 15 tonne hydrolite jacks.

34
Q

What are located on DLR platforms to assist crews with stopping trains?

Additionally, what does this not do?

A

Emergency stop buttons which bring trains to a halt.

Does not isolate traction current.

35
Q

What is an additional track hazard at an incident involving post office automated rail link?

A

Not much space between tunnel walls and train so crews must not enter tunnel until power off and trains stopped. No safe working distance.
