FFP - UNDER RIVER RAIL OPERATIONS Flashcards
Under River Tubes are cylindrical in shape and are constructed of brick, concrete, or tubular cast iron. Some cast iron tubes are lined with concrete. Which is the incorrect point about Under River Tubes?
A) Most tubes are between 14 and 19’ wide, which is only large enough to contain one track.
B) When evacuating passengers, walk the, between the running rails. Do not walk passengers outside the rails due to the 3rd rail alternating sides as it goes through the tube.
C) Most tubes have no access to the adjacent tube throughout the underwater areas.
D) There is very little space between the train and the tube. In the event of a collision or an explosion, it may be impossible to obtain access to the side of the train from the exterior.
B) When evacuating passengers, walk the, between the running rails. Do not walk passengers outside the rails due to the 3rd rail alternating sides as it goes through the tube. (INCORRECT)
(FFP UNDER RIVER RAIL 2.2.1)
- When evacuating passengers, WALK IN AREA OUTSIDE OF RAILS,
OPPOSITE THE 3RD RAIL. (Between rails is unsafe because of
drainage troughs)
Which point about emergency exits and crossovers associated with under River tubes is incorrect?
A) The tunnel to tube transition area is the point where the underground tunnel connects to the Under River tube. In most cases, it is the location of the last emergency exit and the last crossover to the adjacent tube until the other side of the river.
B) Emergency exits may be standard (flush with the sidewalk), or upright (located in the side of a structure). Both types of exits are opened with a subway emergency tool, the triangle key.
C) Exit stairways are constructed of either concrete or metal. The metal stairs are often steeper, with open treads.
D) Crossovers (cross passageways) are connections between adjacent tunnels. They are located only in underground areas and at the ends of under River tubes. Crossovers associated with emergency exits are usually one or more levels above the tracks.
D) Crossovers (cross passageways) are connections between adjacent tunnels. They are located only in underground areas and at the ends of under River tubes. Crossovers associated with emergency exits are usually one or more levels above the tracks. (INCORRECT)
(FFP UNDER RIVER RAIL 2.4, Figure 6A)
- Crossovers associated with emergency exits are USUALLY AT TRACK
LEVEL but may be located on or more levels above tracks.
Standpipes and other fire protection systems and equipment are found in Under River tubes. Which of the following is incorrect about these systems?
A) All under river standpipes in the NYC Transit System, are wet. Standpipes are city main fed. There are no pumps to augment pressure, but Siameses are usually located at the emergency exits closest to the river.
B) 2 1/2” outlets are located every 200’ throughout under River tubes. Section valves are located approximately 600’ apart.
C) Sound powered phone jacks are located at all under river standpipe outlets in all tubes.
D) 20 pound dry chemical extinguishers are located at power removal boxes, approximately every 600’
E) Emergency Evacuation Devices (EED) are located at both ends of each under river tube at the base of the emergency exits
C) Sound powered phone jacks are located at all under river standpipe outlets in all tubes. (INCORRECT)
(FFP UNDER RIVER RAIL 2.7.1)
- Sound powered phone jacks in all under River tubes EXCEPT
JORALEMON TUBE.
Communications in incidents involving under river tubes can be extremely challenging. Which of the following would not be a proper way to communicate at these incidents?
A) If enough personnel are on scene and conditions warrant, the HT relay should be established. The HT relay is the basic means of communication in the subway system.
B) For maximum repeater coverage, the IC 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.
C) Repeater coverage is available in all emergency exit stairways. If repeater use is unsatisfactory in the emergency exit stairwell, a HT relay on Channel 14 should be used.
D) Notify NYC Transit when Post Radios are in use with the subway system. Post Radios may be useful to communicate above ground from one side of the river to the other.
C) Repeater coverage is available in all emergency exit stairways. If repeater use is unsatisfactory in the emergency exit stairwell, a HT relay on Channel 14 should be used. (INCORRECT)
(FFP UNDER RIVER RAIL 2.9.1)
- At present THERE ARE NO REPEATER ANTENNAS at most
emergency exits and NO other repeater coverage inside most
emergency exit stairways. A HT relay on TACTICAL CHANNEL shall
be used.
Additional methods of communication include Blue Light Phones, TA Portable Radios and Sound Powered Phones. Which is the correct point about these methods of communication?
A) TA portable radios are carried by conductors, train operators and TA supervisors. These radios may not work above ground.
B) Members using Sound Powered Phones in the tubes should use handsets for more effective communication.
C) A blue light phone can be used to call outside the system, and can receive calls from outside the system.
D) To call a blue light telephone from outside the system, dial the 2 digit access code and the four digit extension number.
A) TA portable radios are carried by conductors, train operators and TA supervisors. These radios may not work above ground.
(FFP UNDER RIVER RAILS 2.9.5)
B - HEADSETS are more effective than handsets
C - Blue light phone CANNOT be used to call outside system however
it can receive calls from outside the system.
D - To call a blue light phone for, outside the system, DIAL 1 + AREA
CODE (USUALLY 718) + 3 DIGIT EXCHANGE + 4 DIGIT EXT. #

(FFP UNDER RIVER RAIL 3.2)
- E stands for EVACUATION & EGRESS ACCESS POINTS
Ladder 100 is assigned to an emergency exit at a reported explosion in an under river tube. Which action taken by Ladder 100 is incorrect?
A) Ladder 100 consulted the Emergency Exit Guidebook and Operational Guide to verify that they were operating at the correct emergency exit.
B) Upon opening the exit door, Ladder 100 checked for the presence of smoke, haze, odors, unusual sounds, and people in stairwell.
C) Ladder 100 notified the dispatcher which emergency exits they opened, and requested power off on Track #1 due to passengers self-evacuating on Track #1.
D) Ladder 100 descended the stairwell and searched the tracks for approximately 1/2 mile to ensure any self evacuating passengers were not missed in the initial stages of the operation.
D) Ladder 100 descended the stairwell and searched the tracks for approximately 1/2 mile to ensure any self evacuating passengers were not missed in the initial stages of the operation. (INCORRECT)
(FFP UNDER RIVER RAIL 3.3)
- Members should assist evacuating civilians BUT SHOULD NOT BE
COMMITTED TOO FAR INTO A DANGEROUS AREA until a proper
hazard assessment is completed.
Ladder 100 is operating at a fire in a under river tube. The ventilation fans on the Brooklyn side of the tube are operating in supply mode. The ventilation fans on the Manhattan side of the tube are operating in exhaust mode. There in an occupied subway car in the tube, approximately 2500 feet from Brooklyn, and 1300 feet from Manhattan. Which would be a correct thought for Ladder 100 to consider concerning evacuation of the passengers of this car?
A) Evacuate the passengers towards Brooklyn, after ensuring power removal in the affected tube.

- Black Tag
When ambulatory victims have reached the area at the base of the emergency exit stairs, there are several possible removal options. Which of the following is incorrect concerning removal?
A) Passengers may be directed to walk along the track to the nearest station. This decision will be based on travel distance, patient condition, and the status of 3rd rail power.
B) FD members attempting to descend emergency exit stairways must first allow civilians to evacuate.
C) When 2 emergency exits are present, designate an evacuation stairway and an attack stairway
D) A Rescue Train is always the quickest option. The more likely scenario is using the Rescue Train on the same track as the incident.
D) A Rescue Train is always the quickest option. The more likely scenario is using the Rescue Train on the same track as the incident. (INCORRECT)
(FFP UNDER RIVER RAIL 7.2.2)
- Rescue Train TAKES TIME TO PUT INTO OPERATION.
The more likely scenario is using the Rescue Train in adjacent tube.
Using Rescue Train on same side as incident is UNLIKELY.
Removing non ambulatory victims from the tube will be labor intensive and will require increased personnel and logistical support. Which choice below is incorrect concerning the removal of non ambulatory victims?
A) Victim removal teams would spread out from victim location to emergency exit. Victims would be passed from team to team in a relay fashion.
B) SKED stretchers have proven to be the most efficient way to move non ambulatory victims.
C) Rail carts, which ride on the tracks, are the primary method for moving patients and equipment.
D) Rescue Trains may also be used. Potential rescue trains should be swept for secondary devices by law enforcement personnel prior to deployment.
B) SKED stretchers have proven to be the most efficient way to move non ambulatory victims. (INCORRECT)
(FFP UNDER RIVER RAIL 7.2.2, Note 7.3)
- SKEDS are USEFUL to move patients long distances over difficult
terrain.Relay teams are MORE EFFICIENT method of moving non ambulatory
victims.
When FD units operate at fires in an under river rail incident, they will confirm power removal, but operate as if power is on. Which of the following guidelines is incorrect about engine operations?
A) It is most likely that hand lines will be stretched through an emergency exit.
B) Units shall use the FT-2 Nozzle
C) When stretching a hose line through a train, it may be necessary to chock numerous car doors to reach the fire. Many chocks would be required.
D) Several units may need to work together to stretch and operate a hand line.
E) Consider the use of dry chemical extinguishers, which are located at the blue lights in the tube.
A) It is most likely that hand lines will be stretched through an emergency exit. (INCORRECT)
(FFP UNDER RIVER RAIL 8.1.3)
- Most likely that hand lines will be OPERATED FROM STANDPIPE
OUTLETS.If incident is very close to emergency exits IT MAY BE FEASIBLE to
stretch a hand line via the emergency exit.Cannot operate from an emergency exit in a way that will hinder
passenger evacuation.
