Study Notes

Tunnel Infrastructure and Safety Features

Each tunnel is equipped with 6” wet standpipes featuring 2 ½” outlets located every 250 feet for fire safety.
Blue Light Stations (BLS) are situated at both ends of the Upper and Lower Platforms; these activate the undercar deluge system and shut down traction power.

Emergency Equipment

Emergency Equipment Room 106 is positioned at the East end of the Lower Platform, near Emergency Stairs 1/2/3 ABC.
Train Control & Communications (TC&C) Room 339 and the Fire Control Panel (FCP) are located at the West end of the Ancillary Level.

Power Hazards

There exists a 750 VOLT DC third rail located outside the track, presenting electrical hazards.
An emergency power cable, rated at 34,500 VOLT AC, runs approximately 6 feet above track level on the AL side, supplying station power through an emergency generator if there is a DWP failure.

Auxiliary Power Rooms

Two Auxiliary Power Rooms: RM 302 (East) and RM 354 (West).
Traction Power Substation Room 332 is centrally located on the Ancillary Level.

Ventilation System

Emergency fans are installed at each station end for ventilation, with a computer-controlled system operational for various scenarios; manual control is available at the Emergency Management Plan (EMP).
Ancillary areas lack mechanical ventilation but utilize room dampers for air control.

Blast Relief Shafts

Two Blast Relief Shafts (BRS) are situated, one adjacent to each end of the station: one near the North Fire Department Connection (FDC) on Vermont Ave and another on Wilshire, east of Shatto Place.

Emergency Response Infrastructure

Multiple emergency Blue Light Stations are distributed throughout the platforms to facilitate quick reporting and response during emergencies.
