ABSTRACT
Railway is the backbone of Indian transportation system. To operate the railway system, it is necessary
to manage different functionalities. India Railway has many departments to operate the system correctly
and cost effectively. To minimize the risk and to maximize the profitability railway has an efficient
Railway Management System. Centre for Railway Information Systems or CRIS is an important Railway
Management Information Systems. The purpose of this paper is to give an overview about Centre for
Railway Information Systems. Different projects under CRIS has also discussed here. Different emerging
technologies use by CRIS has also discussed here. Flow charts are used to explain the ticket booking
concept easily. Contact information of different officials has also shared in this paper.
Keywords: Centre for Railway Information Systems, Railway Information Systems, CRIS, Railway
Management System etc.

Globally Railway is one of the biggest networks of transportation. To manage and operate the railway
network correctly and smoothly the whole system needs a strong and reliable Information system and a
strong Information Technology infrastructure.
Centre for Railway Information Systems or CRIS is an organization under the Ministry of railways,
Government of India. The main task of CRIS is to design, development, maintenance of different
Information Systems used in India Railway. It has been successfully implemented by the unique
collaboration of Information Technology professionals with the experience Railway personals. It has
used different modern technologies to successfully execute all the projects under CRIS. Digital railway

is one of the parts of Digital India program. CRIS is an important information system for Indian Railway
to manage different departments systematically.

Objectives
Railway is very important mode of transportation for the passengers and for the goods. It is a huge network
spread all over the country. The objectives of this study are:
™™ To learn about the Centre for Railway Information Systems - CRIS
™™ To know the different projects executed by CRIS
™™ To know the different Technologies used in CRIS
™™ To know the useful contact information of the officials
™™ To discuss the Advantages and the Challenges to CRIS
™™ To get a futuristic concept in CRIS

Methodology Adopted
The research work entitled ‘Projects of Centre for Railway Information Systems (CRIS)-The automated
Railway Management System: A Case Study’ is an interdisciplinary work and it is theoretical in nature.
Various secondary sources from different areas and subjects viz. Information Technology, Communication
Technology, ICT, Information System, Railway management, Railway Information systems etc. are used
to complete this work. Although the concept of this research is to study the different technologies used
in CRIS. Various web sites are analyzed and reviewed to gather different information and to make the
case study.

Projects under CRIS

Different projects have successfully executed under CRIS. The projects are as follows:

Software Projects
CRIS has develop, implements and maintain various types of software projects. The projects are as follows-
™™ Ticketing and Passenger
Ticketing and passenger service is one of the main tasks of CRIS. The details are described below-
™™ Unreserved Ticketing System
Unreserved Ticketing System is one of the important tasks of CRIS. UTS is used to book
the unreserved tickets by the passengers at railway counter. In August 2002, he unreserved
ticketing system has began as a pilot project at Northern Railway. One of the pioneers of this
centralized ticketing system was self-printing ticket machines (SPTMs) but this standalone
system was phased out with the advent of UTS.

Initially, there was the central hardware architecture at station level because of the event of
network failures it could server to the customer effectively using the dumb terminals and
dot matrix printers. As the reliability of the network has improved, a new design has been
implemented by introducing thin client machine supply to booking operators. Each Zonal
Railway is responsible for operating UTS counters and running services smoothly. CRIS only
maintains the UTS application and ensures business continuity at the system level.
The passenger may book the unreserved tickets from the following system:

™™ Passenger Reservation system

Passenger Reservation System is one of the challenging tasks of CIRS. Passenger Reservation
system is used to book reservation ticket for the passengers. It is world largest Passenger Reservation
system which is developed, implemented and maintained by CIRS.
The main advantage of this system is that anyone can book the ticket from anywhere and anytime
(except the maintenance time).
Information and Communication Technology (ICT) and different modern technologies like
Artificial Intelligence, Cloud Computing Technologies, Big Data Analysis, Data Mining etc. has
working simultaneously to execute the system smoothly. Country-wide Network for Computerized
Enhanced reservation and Ticketing(CONCERT) which is a distributed database model having 3
tier Client Server architecture with 4 data centres at New Delhi, Mumbai, Kolkata, and Chennai
has also perform a vital role in Passenger Reservation System.
The passengers get the facility to reserve train berth/seat upto
6 person at a time from anywhere. They might book the ticket
using website in online mode or through the mobile phones
without required to go to the rail reservation centers.
Indian Railway Catering and Tourism Corporation (IRCTC)
is the Subsidiary company under Indian Railways, Ministry of
Railways, Government of India. It provides ticketing, catering
and tourism services for the Indian Railways. CRIS has
designed and hosted the Next Generation e-Ticketing (NGeT)
System for the ticket booking to the passenger.

CONCLUSION
Railway is a very essential mode of transportation for all the countries. The countries economy is
completely depending on the railway system. The more strong the railway networks have a country, the
more revenue it would generate. Thus, to become more sustainable, reliable and cost-effective mode of
transportation, the railway system does not have any alternative.
In this study it is only consider the features of CRIS and the current projects of CRIS. There are many
other organizations but CRIS is only considered here for the study. This study is restricted to the Indian
Railway system only. The emerging technologies have just given an overview in this study. At present the
scope of implementation of the emerging technologies is very large. CRIS is a very stable Information
System for Indian Railway. It is expected CRIS will give better services in near future too.
