METRO RAIL DESIGN CRITERIA SECTION 9 / SYSTEMS

DE304.09 9-90 Revision 4 : 05/09/12

Metro Baseline Re-Baseline: 04/29/10

subsystems and/or functions shall be considered part of the communications system

and its design; including certain requirements related to expanding the subsystems

to fulfill future needs:

• Radio

• Telephone (TEL)

• Public Address (PA), Visual Message Signs (VMS) and Transit Information

System (TIS)

• Closed Circuit TV (CCTV)

• Cable Transmission System (CTS)

• Supervisory Control and Data Acquisition (SCADA)

• Intrusion Detection and Controlled Access

• Central Control Consoles and Displays/Rail Operations Control (ROC)

• Gas Monitoring

• Seismic Detection

• Fire Alarm

• Emergency Management Panel

• Communications Power System

The above subsystem design requirements are detailed in the following sections of

this document. Communications requirements for any communications based Train

Control System are not contained herein.

The Rail Operations Control (ROC) will contain the necessary displays, control

consoles communications apparatus and the operating personnel responsible for

the overall safety and security of passengers and the daily operations of the trains,

stations and all supporting wayside apparatus. The ROC will serve as the focal point

from which all LRT System operations will be supervised, regulated and controlled.

Yard Control shall contain the necessary displays, control panels, communications

apparatus and personnel to manage train movements and consists within the Yard.

Maintenance Control will be responsible for vehicle, personnel, and inventory control

within the shop, personnel, maintenance equipment and inventory control within the

LRT and HRT System, and communications between the shop and operations

facilities, `including Central Control and Yard Control. In addition, it will have

maintenance-oriented management information services including vehicle and other

system apparatus histories inventory analysis, and maintenance forecasting.

The Communications system shall consist of private voice and data circuits

connecting the ROC with stations and other areas within the LRT and HRT system.

These functions shall be provided by communications network elements: radio;

telephone; public address; closed circuit television; cable transmission, supervisory

control and data acquisition; intrusion detection and access control; gas monitoring

and seismic detection, ROC and other subsystems equipment. These elements are

described in the following paragraphs.

A. Radio Transmission shall provide the primary voice communications services for

all areas. Two-way voice communications via radio shall serve trains and

maintenance Vehicles and Portables with channels provided for operations,

maintenance, security and fire/police emergency functions.
