Tender invited for Development of Train Collision Avoidance System

ISO 9001: 2008 Effective from 18.06.2012 RDSO/SPN/196/2012 Version 3.1.1
Document Title : Specification of Train Collision Avoidance System
x. RS485 ports (minimum two & upgradable to six) for interfacing with OFC/
Quad cable for connectivity with other Station unit. RS485 ports shall be
internally wired through built-in modem for interfacing with Quad Cable
Network.
xi. An Ethernet port for connecting it to Centralized Management System.
xii. USB 2.0 interface for downloading of log & other data for diagnostic
purposes.
xiii. Interface for connecting 21” LCD panel in a room at the station.
xiv. Interconnecting cables
4.5 RFID tags shallbe fitted on point zones, near Signals & track in block section
for giving Track Identification Number (TIN) information to loco unit, location
correction, identifying signal by Loco unit& for direction determination in
tunnels. Each RFID tag shall communicate the distance to next RFID tag.
4.6 RFID tags at all the places shall be duplicated with identical information.
4.7 TCAS shall be universally suitable for various types of sections of Indian
Railways e.g. Stations equipped with Relay interlocking, Electronic interlocking,
Multi-aspect Colour Light Signalling, Electromechanical Signalling with Multiple
Aspect Colour Light Signalling, Automatic Signalling (Not in the current Phase),
Suburban (excluding underground railway sections), Multiple Line, Intermediate
Block Signalling Sections; turnouts of all types having different speed
potentials.
4.8 TCAS shall be suitable for all types of electric and diesel locomotives, including
all types of microprocessor based locomotives, Distributed Power Wireless
Control System (DPWCS) locomotives running on Indian Railways. In case of
Microprocessor based locomotives, the braking system of TCAS will be suitably
interfaced with the computer controlled braking system of the locomotive.
However, the loco unit in ‘Coupled/ Banking’ mode shall not apply any
brake.
4.9 TCAS shall be suitable for Air/Vacuum /Dual/Electro-pneumatic Brake
system/CCB/EP70 of Diesel and Electric Locomotives, EMUs/ DMUs/ MEMUs
as well as any other self-propelled vehicles treated as train.
4.10 TCAS units shall be capable of working in all electrified as well as nonelectrified
territories. It shall be suitable for use on AC/DC
EMUs/DMUs/MEMUs/single or multi-headed electric/diesel locomotives/
banking locomotives.
4.11 TCAS Network shall be suitable for train speeds atleast up to 160 km/h.
4.12 The Loco unit & Station unit shall work on the DC power supply & shall have
battery backup.
4.13 The Loco unit, Station unit & Track side equipments shall not in any way
infringe the schedule of dimensions being followed by the Indian Railways.
4.14 TCAS shall be capable of giving following three levels of brake commands for
train braking
i Normal Brake command
ii Full Service brake command
iii Emergency brake command
& the Brake Interface Unit (BIU) shall apply normal, service & emergency
brakes of locomotives respectively based on the type of brake command
through existing brake system of locomotives. Also, equipment shall have
facility to give additional command in conjunction with Normal Brake / Full
Service Brake / Emergency Brake which shall be used to develop higher brake
cylinder pressure corresponding to loco independent brake, if train is a light
engine.
4.15 The fixing of the equipment, including antenna should be rugged enough so
