(2) TB 70 - Metro Rail Blue Line Flashcards
What Rail Lines make up the Light Rail Network?
- Metro Blue Line
- Metro Green Line
- Metro Gold Line
- Metro Exposition Line
- Metro Crenshaw/LAX Line
- Regional Connector (Gold Line to 7th/Metro Center)
Light Rail Vehicles (LVR) consists of track and stations that are fed electrically by a ______ System as opposed to a third rail system like the Red/Purple line.
Catenary
(Catenary lines are fed from local utility substations)
The 34.5 kV AC from Traction Power SubStations (TPSS) is converted by a transformer/rectifier to _____ volt DC and fed through the Pantograph via Catenary lines in order to operate passenger vehicles.
750
Emergency Blue Light Stations (BLS’s), which have “mushroom” buttons to de-energize Cantenary lines, are located at:
-Traction Power SubStations (TPSS)
-cross passages
-elevated stations
-remote access points.
(If time permits, always call Rail Operations Control (ROC) first.)
True or False?
Light Rail Vehicles (LRV’s) do not weigh any LESS THAN heavy rail cars
True.
(they often weigh more).
Typically, the Light Rail Vehicles on all lines travel on two parallel tracks on the “right side of the road” like our motor vehicle traffic. This is important to know because in some of the emergencies that you will be involved with, the Metro authorities may decide to “single track.”
This means?
-trains may be traveling on an “uninvolved” track from both directions.
(ALWAYS look both ways before crossing)
It is also important to know the configuration and locations of the Guideways and stations in your _____ district because each location poses its own set of accessibility, exiting, and water availability considerations.
first-in
The vast majority of “train versus auto” incidents occur at ______ sections of the Guideway.
at-grade
______ stations and track are generally those transitional sections of the Guideway that take it from tunnels to at-grade or elevated sections.
U-cut
Whether a light rail track is at-grade, in a tunnel, at a station, or on an elevated structure, it will be near a mile marker.
Milepost markers are used throughout the rail network and are marked not to exceed distances of more than _____ mile.
1/10
At-grade stations and Guideways comprise the majority of the Light Rail System.
What Fire/Life Systems are at at-grade Stations?
-Emergency Lighting
(There are NO STANDPIPES installed in at-grade stations located in the City of Los Angeles.)
It is highly recommended that LAFD stations located in areas that have at-grade tracks brush up on extrication techniques contact the local ________ to exchange ideas and info on rail-related incidents.

Tunnels and Underground Stations
COMMON Fire/Life Safety Features:
- Class I Standpipes
—1st st Tunnel and Flower St Tunnel have the ONLY AUTOMATIC WET standpipes (sufficient pressure). The rest have MANUAL WET standpipe systems (need LAFD augmenting). - Lighting
— 90 min of battery backup - Blue Light Stations (BLS)
—Communicate with ROC and ability to de-energize rail in that segment - Emergency Walkways
—At least 30 inches wide - Antennas for LAFD radio transmission
—in repeat setting. 2,4,6,7,12,15,16,17
Tunnels and Underground Stations
Class I standpipes are located between ____ and ____ ft apart and are provided with FDC’s.
250 to 300 ft
Tunnels and Underground Stations
The ______ standpipes are ineffective until the Fire Department’s pumping apparatus can augment the system through the FDC’s.
manual wet
Unique Fire/Life Safety Features of Light Rail TUNNELS and STATIONS (BLUE, GOLD, EXPO):
(This EXCLUDES the Flower Street Tunnel of the Blue Line)
- Cross Passages and Emergency Exits
— 750ft apart.
—Emergency hatches mount flush, are with panic hardware, and allow LAFD access with a hydrant spanner. - Blue Light Stations
— Located at each cross passage and end of platforms
— Contain Emergency Trip Station (ETS) with a “mushroom” button
— Contain Emergency Telephone (ETEL) with automatic ring-down to ROC
— Under-Car Deluge Sprinkler System button located at ETS at end of platforms - Water System
— At every cross passage and every 250 to 300 ft throughout tunnel, 2-1/2” outlets.
— Fire Hose Cabinets with 100’ of 1-1/2” rubber lined hose and spray nozzle, a 2-1/2” FD outlet, and 40 BC dry chem or CO2 extinguisher. - Ventilation
— Fans located at each end of stations and at each portal entrance (if system is greater than 1000 ft). The fans are bi-directional
— Best to allow ROC to control them unless there is a proof of need to change their configuration. - Emergency Management Panel (EMP)
— Located on the mezzanine (concourse) lvl, or outside station entrance at street lvl
Tunnel Stations
The FDC to each station is easy to find.
It is on or around the _____ of the station by the main entrance.
address side
Activating the automatic sprinkler system (under-car Deluge system) will also de-energize the _______.
Overhead Catenary (OC) line in that section.
Tunnel Portion
The cross passage is used for the TRANSFER of passengers (or emergency responders) from one bore to another.
A _____ will identify each cross passage.
red exit sign
(Keep in mind that an exit sign does not necessarily lead one to the public way but leads to a Point-of-Safety. A Point-of–Safety is a location that brings the patrons out of harm’s way. The Point-of-Safety in this case is the next tunnel.)
Concerning the operation of the Emergency Ventilation fans, it is essential that first-responders have all the facts concerning:
-Train’s location
-Passenger Evacuation direction
-Fire Dept’s access location
(Emergency Ventilation Operations Procedural (EVOP) manuals is located inside the EMP’s of each light rail stations.)
The Emergency Ventilation fans will be found at Light Rail enclosed system stations, system underground or enclosed trainways greater than ______ ft.
1000 ft
EMP features:
-Indicate location (zone) and nature of alarm
-status of ventilation fans (if applicable)
-recall the elevators
-stop escalators that are downward flight
-Public address system
-two land lines (dial 9 to reach outside lines)
