FFP - Under River Rail

Question 1

UNDER RIVER RAIL OPERATIONS

Answer 1

• Most tubes have no access to the adjacent tube through the
  underwater areas. Three exceptions are:
  
  1. 63rd street tunnel - most recently constructed - precast concrete -
     most susceptible to flooding if damaged.
  2. Lexington Ave tunnel - Contains 4 tracks
  3. 161st street tunnel - Contains 3 tracks
• All under river standpipes are wet - NYC Subway standpipes are dry
• Sound powered phone jacks are located at standpipe outlets
  (Exception: Joralemon Tube)
• Subway Repeater - often there are breaks between repeater zones
  inside under river tubes.
• There are no repeater antennas at most emergency exits, and no
  repeater coverage inside most emergency exit stairways. A HT relay
  on the tactical channel shall be used.
• All NYCT under river tubes have reversible fans at both ends, usually
  in the vicinity of the emergency exits nearest the water. Exceptions:
  there are no fans on the Brooklyn side of the Greenpoint-Jackson Ave
  Tubes, or on the Bronx side of the 149th street tubes. There are no
  ventilation fans or ductwork in the tubes themselves.
• Preparations for operations in under river tubes have 3 main elements
  
  1. Reconnaissance
  2. Planning
  3. Logistics
• Removing non ambulatory victims - skeds useful to move patients
  long distances over difficult terrain.
• Rail carts are the primary method for moving non ambulatory patients
  (More efficient than any other method)
• Victims removed in the following order:
  
  1. Ambulatory victims
  2. Non ambulatory victims
  3. Victims requiring Disentanglement / Extrication
  4. Black tag (deceased victims)
