IRSE Seminar on
Role of Modern Signalling, Telecom & ICT Systems
in Making IR a World Class Rail Network
• What is the role that ICT can play in modernisation and upgradation of railways?
• What are the key ICT requirements?• What are some of the more interesting
technologies and approaches?• What are key applications?
ICT Verticals• Train operation• Commercial• Passenger Informatin• Asset Management
– Track, Land, Bldgs & Structures, Power, Signalling– Locos, Coaches, Wagons
• Administrative – ERP Solutions– HR, Accounts, Administration, Pension– Projects, MIS, Stores, Procurement
Role which ICT can play in railways• Increase in operational flexibility• Improve asset utilization – Availability• Raise effective capacity • Cost savings • Increased visibility• Improve customer satisfaction• Integration of dispersed elements
Infrastructure, Operations, rolling stock, safety, energy etc
• Informed decision making • Customer Centric Organisation – Right
information at right time and at right place

Integrated ICT Infrastructure for IR• Physical Communication Infrastructure
– OFC cable connecting activity centers 35000 km available, 50,000 km by 2012
– Most of major stns, yards, control centers, maintenance depots, Admin offices are on OFC n/w
– Total 7000 stns - Approx 100 A category, 400 B category dealing with 80% of traffic and balance C & D category stns.
– Physical access n/w on OFC to key activity centers and wi-max for other distributed applications is needed.
– Tower available (approx 1000 nos) at most imp stns and shall be needed elsewhere.
– Shall bring in all Engg & operational staff in the n/w for creating and accessing data/voice
– Shall lease capacity in interim period where Rlys n/w is taking time
• Can be developed by IR/RailTel with it’s own resources
• Optical Fiber cable
– OFC laid - 36275 RKM & Commissioned- 32924 RKM
• Backbone Layer
– STM 16 based backbone network covering about 26261 RKM (with Multiple rings on common section of 18948 RKM)
– DWDM implemented in 10500 RKM
• Total PoPs
-- Major Cities: 490 -- Minor Towns/Cities: 2950

Reliable Passenger Information?• Uncertainties in train operation
– Large and Widely Spread Railway Network– Different Type and Class of Trains to Varied Destinations– Local and social problems
• Different class of people• Scarcity of reserved Accomodation• Information is Important
– before reaching station– at station– during train journey– On arrival
• Possible through Centralised Information Dissemination System
Train Safety• Station Areas reasonably protected through vehicle detection
and interlocking to guard against Human Error• Station Managers are Stationary & in communication with
control• Block Sections are also covered• Loco’s/Trains Need means of Communication and safety
equipment to guard against human error• Driver being mobile, reliable communication is challenge• GSM-R for Loco to control communication • On Board Safety System-
• AWS• Train Protection and Warning System• Anti Collision Device.
• Disaster management System.
Security at Railway Stations and Trains• Important in the interest of National Security• Integrated IP based Surveillance System
– Networked IP Cameras linked to security control room– Baggage Scanning Machines– Metal/mm wave doors/detectors
• Centralised data storage & processing– 24X7 monitoring– Identification of unusual objects & movements– Automated information and escalation to concerned
agencies as planned– Preventive action before incident!
• Railways use GIS in their Organisation for Infra Mgmt & Maint plg– Engg track, bridges, tunnels & yards– Electric Power Distribution N/W– Signalling installations & comm N/W– Real state Mgmt– Maintenance of locos & other rolling stock –
depot management– Shipment & Asset tracking– Planning for replacement, works in progress,
sensitive spots– Natural terrain, site conditions

SIMRAN : Train Information System• Technology Mission for Railway Safety (TMRS)” one of the
project selected was “Satellite Imaging for Rail Navigation (SIMRAN)” .
• Purpose of the project is to standardize the GPS/GSM technology for tracking of trains and to disseminate the train running information to the passengers through Internet, SMS on Mobile phones, Call Centers, IVRS and through Train Indication Boards at the Railway Stations.
• Use by Operators to schedule train operations, by maintainers to schedule maintenance blocks.
• GIS based display at SM’s/ Control panel to exactly know train location.
• GIS based Centralised Train Operation and Information system
SIMRAN..
• Equipment Element sensors (either on board or on ground) detect anomalies of Infrastructure/ rolling stock components
• Information is transmitted to Controllers/ crews/ Maintainers for immediate action or logging for unscheduled maintenance
• Conditions detected include: Degraded Signalling elements, Track defects, Bridge/ culvert inconsistencies, overheated bearings and wheels, deteriorating bearings, cracked and flat wheels, derailed wheels, excessive coach/ wagon hunting, dragging equipment, excessive lateral and vertical loads, LC Gates obstructed/ blocked, OHE snapped etc.
• Vehicle-mounted sensors to detect various defects of ground based assets: like: Rail flaws, broken rail, misaligned track, corrugated track, and excessive rail stress could be detected
• GPS, DGPS or OFC based RFID sensors can determine location of defects and conditions
• Data can be transmitted over data link to control center and maintenance depots.
• Improves reliability, availability, and utilization rate of locomotives.
