FFP - Under River Rail Operations Flashcards
What is the shape of tube?
Cylindrical.
How are they constructed?
Of brick, concrete or tubular cast iron.
Some cast iron tubes are lined with concrete.
Tube walls are b/t 2’ and 2 1/2’ thick.
How wide are the tubes?
Most tubes are b/t 14’ and 19’ wide, which is ONLY large enough to contain ONE track.
How should passengers be evacuated from an under river subway tube?
Evacuate passengers along space OUTSIDE of running rails, OPPOSITE 3rd rail.
- It would be unsafe to walk b/t the running rails due to the drainage trough.*
- 3rd rail may change from side to side.*
Do most tubes have access to the adjacent tube throughout the underwater areas?
No.
Regarding crossovers, what are the exceptions?
a) 63rd St. (two level, two tracks)
b) Lexington Ave. (contain 4 tracks).
c) 161st St. (a set of 3 tracks)
Regarding the 63rd St. tunnel, the two tacks that run through the UPPER level are separated by what?
Concrete partition. Many openings exist in this partition throughout the under river areas.
Which tunnel would be the MOST susceptible to flooding?
The 63rd St. tunnel due to construction features.
In most cases, where is the last emergency exit and the last crossover located?
At the tunnel to tube transition area.
Square underground tunnel section connects to the round under river tube.
Crossovers aka cross passageways
Connections b/t adjacent tunnels.
They are located ONLY in underground areas AND at the ends of under river tubes.
What is the most common crossover?
A crossover at track level.
Crossovers associated with emergency exits are located where?
They are usually at track level BUT may be one or more levels ABOVE the tracks.
Are all under river standpipes in the NYCT system wet?
Yes.
They are city main fed.
Where are siameses USUALLY located?
At the emergency exits CLOSEST to the river.
In all cases, check the sign.
How often are the 2 1/2” standpipe outlets located?
Every 200’ throughout under river tubes.
Indicated on Side “B” of the operational guide as numbers in RED circles.
Where are section valves located?
Approximately 600’ apart.
They are often found at the based of emergency exits.
Where are sound powered phone jacks located?
At standpipe outlets.
Exception - Joralemon Tube b/t Brooklyn and Manhattan
The standpipe outlet can be used to?
Figure 7 - Pinpoint the location of the incident.
They are sequential.
*2.7.3 Used to provide an APPROXIMATE location of an incident.
Where are Emergency Evacuation Devices (EED) located?
At both ends of each under river tube,
at the base of emergency exits.
*Also located near stations, at the first blue light SOUTH of the station, on the SOUTHBOUND track.
If using the flat side up of the EED to move passengers from one train to another, what is used as guides?
Ropes or hooks.
At present, are there repeater antennas at most emergency exits?
No
Is there repeater coverage INSIDE most emergency exit stairways?
No
To ensure maximum repeater coverage, the I/C should?
Ensure that a member operating on the repeater channel is at street level in a position at the CLOSEST station on BOTH sides of the river.
Blue light phones are found?
Near the emergency power removal boxes, approximately 600’ apart.
Who can you call from this phone?
The T/A trainmaster or the phone in the token booth of the nearest station.
Who carries T/A portable radios?
a) Conductors
b) Train Operators
c) T/A supervisors
* These radios MAY NOT work above ground.*
Is it good practice to use the Post Radio during subways operations?
No. Do not use post radios in the immediate vicinity of
a) signals
b) communications equipment or
c) train operator cabs
due to the possibility of electrical interference.
Who do we notify when utilizing the Post Radio?
Notify NYCT.
*They may be useful to communicate ABOVE ground from one side of the river to the other.
What are the parameters of the blue light phone?
It CANNOT be used to call outside the system but can RECEIVE calls from outside the system.
1+area code (718)+three digit EXCHANGE+four digit EXTENSION.
Where are the NYCT under river tube reversible fans located?
At both ends, USUALLY in the vicinity of the emergency exits NEAREST to the water.
What are the exceptions to the reversible fans?
There are no fans on the Brooklyn side of the Greenpoint-Jackson Ave. Tubes OR
on the Bronx side of the 149th St. tubes.
There are no ventilation fans or ductwork in he tubes themselves.
Side “A” of the operational guide contains what info?
a) Maps
b) pictures
c) Information to locate a particular set of tubes,
d) the associated emergency exits and stations.
* The I/C can use this side to determine where to assign resources.
* Individual units can use it to understand where they need to go to carry out their assignments.
Side “B” of the operational guide contains what info?
a) Diagram of the tube
b) Information about emergency exits,
c) distances and
d) crossovers.
What does the acronym “LIVES” stand for?
Location of incident/Life hazard Incident information Ventilation Evacuation/Egress & access points Safety
If passengers are self evacuating…..
Request power-off on the affected tracks.
Where will the Command Post be established?
In most cases, the initial Command Post will be located at the station CLOSEST to the tunnel, in the BOROUGH of the FIRST ASSIGNED Deputy Chief.
Preparations for operations in under-river tubes have three main elements:
Reconnaissance
Planning
Logistics
Who would be a logical choice as a recon unit?
A Rescue or Squad company.
Metering capability
1 hour cylinders
Knowledge of structural issues.
The order of victim removal is
1) Ambulatory victims
2) Non-ambulatory victims
* Red Tag (Immediate Transport)
* Yellow Tag (Delayed transport)
3) Victims requiring Disentanglement/Extrication
* Red Tag (Immediate Transport)
* Yellow Tag (Delayed Transport)
4) Black Tag - Deceased victims.
What three items must we consider if we decide to move ambulatory passengers along the track to the nearest station?
1) Travel distance
2) Patient condition
3) The status of 3rd rail power
List, in order, the three ways to remove ambulatory victims out of a tube.
a) Direct passengers to walk along the track to the nearest station
b) Emergency Exit Stairways
c) Rescue train
What are the two possible scenarios for use of rescue trains?
1) A rescue train may be used on the track in the ADJACENT TUBE, accessed via the emergency exit crossover or
2) A rescue train on the same track AS INCIDENT.
When should potential rescue trains be swept for secondary devices by law enforcement personnel?
Prior to deployment.
The primary method for moving patients and equipment?
Rail carts, which ride on the tracks.
More efficient than any other method
What four options are available to remove NON-Ambulatory victims from a tube?
1) Victim removal teams
2) SKED stretchers
3) Rail carts
4) Rescue trains
What is one of the most important INITIAL DUTIES of SOC units?
Atmospheric monitoring.
For extended operations into a tunnel with a distance of UP TO ____’ FROM THE POINT OF ENTRY, consider using SOC units with their supplied air cart and hose.
300’
What is the voltage of the lines that run throughout the tubes at ceiling level?
1,000 volts
These lines are NOT DEACTIVATED by routine requests for power removal.
What are indications of train movement?
Increased noise levels and powerful air movement.
Indications of an approaching train are…..
A distant light reflecting on the running rails or vibration in the tracks.
Are SCBA face pieces equipped with APR adapters and canisters required?
Members MUST have these items.
What can a waterflow be caused by?
Either a failure of the tube wall or by a ruptured standpipe.
