Sound Transit Light Rail
Sound Transit Light Rail plans include much more than the DSTT.
A rail line will run from downtown Seattle to Tukwila by July 2009.
Extensions:
Airport Station
University link
North, East and South Link
Downtown Seattle Transit Tunnel (DSTT)
The Downtown Seattle Transit Tunnel (DSTT) presents a significant communications challenge:
>Passengers, buses, and trains must interact efficiently and safely.
>Using multiple stations, buses and trains must share the same roadbed.
>And everyone needs to know what is happening and when.
Communication Challenges
Communication Solutions
Integration of all communication systems, and a design for high availability, enables Sound Transit to meet their communication challenges.

System Integration
Backbone/WAN
Provides the communications infrastructure for:
– Field Control System (FCS)
– Central Control System (CCS)
– Public Announcement and Visual Message Sign (PA/VMS)
– Closed Circuit Television (CCTV)
– Emergency/Office Telephone System
– Access Control System (ACS)
Backbone/WAN• A bi-directional, high bandwidth fiber optic SONET
Ring/Wide Area Network (WAN) provides timely, reliable, and accurate voice, video, and data communications between Sound Transit stations and control centers.
• Redundant: fire or other catastrophic events cannot destroy both communications paths or disconnect any more than one Station or facility from communications with either the King County Metro Link Control Center.

Central Control System (CCS)
Central Control System Map
The CCS displays an icon-based map across multiple screens. Operators can monitor and access devices in all stations throughout the DSTT.
Central Control System (CCS)
• Vehicle communications• Traction electrification
system• Intrusion detectors• Fire alarms• EMPs• Station electrical equipment• Fare collection equipment• Flood detectors/sump pumps• Communications equipment• Radio amplifiers• Access control devices• Fire suppression system
Monitors:• Tunnel ventilation equipment• Station ventilation equipment• CCTV• Signal system devices• Emergency telephones• PA/VMS• Station lighting• Elevators/Escalators
Monitors and Controls:
Field Control System (FCS)
>The Field Control System is the bridge between DSTT devices and the Central Control System.
>It collects information from networking, monitoring, and control devices.
>It relies on many Programmable Logic Controllers (PLCs) for routine tasks.
>The PLCs “talk” to a field server.>An Emergency Management Panel can
communicate directly with the PLC system if the main communications backbone is disabled.

Emergency Management Panel (EMP)
An Emergency Management Panel (EMP) can request control of the Downtown Seattle Transit Tunnel communications system in an emergency situation. EMPs are located at station surface or mezzanine level entry points
Closed Circuit TV (CCTV)
From an ICC Workstation:Select, monitor, and control multiple camerasPlayback preset or user-selectable periods
Closed Circuit TV (CCTV)
Massive Storage:Cameras recorded 24/7Video retained for 30 daysLocal storage at each station in high resolution for four days
PA/VMS System
ICC Workstation - Message Control
Public Address (PA) and Variable Message Sign (VMS)
Pre-recorded or ad-hoc audio and/or visual messages can be sent to stations, zones, or groups.
Immediate or scheduled deliveryLive PA messaging
Messages can be saved for later use. Automated background messages for passenger information/safety
Variable Message Signs (VMS)
Emergency Telephone System
Phones located throughout the Light Rail system.
Direct access to an ICC workstation or emergency operator.
Calls are recorded.
Emergency Telephone (ETEL) – Non-Public Access
Passenger Emergency Telephone (PET) – Public Access
ICC Workstation provides Telephone Control

Emergency Telephone (ETEL)
Emergency voice communications from areas accessible by Sound Transit personnel or other first responders.
Keypad, display, and handset
Equipped with speaker for paging
Blue beacon helps locate the site

Networks
• Control System Network (CSN): uses the Network Management System (NMS) and a series of virtual LANs to monitor/control devices and manage emergency telephones, PA/VMS, and CCTV
• Office Services Network (OSN): manages public telephone, maintenance, and general computing – separated from CSN for security
