PASSENGER RESERVATION SYSTEM(PRS/SC)

Secunderabad (Telangana)

Building Profile

Reserved travel by Indian Railways is facilitated by the Passenger ReservationSystem (PRS). PRS provides reservation services to nearly 1.5 to 2.2 millionpassengers a day on over 2500 trains running throughout the country. The PRSApplication CONCERT (Country-wide Network of Computerized EnhancedReservation and Ticketing) is the world�s largest online reservation application,developed and maintained by CRIS. The system currently operates from 5 Datacentres located at New Delhi, Kolkata, Mumbai, Chennai & Secunderabad. Theserver clusters are connected together by a core network that enables universalterminals across country, through which the travelling public can reserve a berthon any train, between any pair of station for any date and class

The Passenger Reservation complex located at Secunderabad was built in the year1989, PRS houses important servers where the disaster recovery servers areinstalled for replicating of online information of the entire ticketing system onIndian Railway.

MOORE MARKET COMPLEX,SOUTHERN RAILWAY

Chennai (Tamil Nadu)

Unit Profile

The Moore Market Complex (MMC) is a commercial building complex and railwayterminus for the Chennai suburban railway system, situated in Park Town, Chennai.The name Moore Market comes from a market that used to exist at the sitebefore being demolished to make way for the expansion of the Chennai Centralstation.

Moore Market was originally built to house the hawkers in the Broadway area ofMadras. Its foundation stone was laid by Sir George Moore, president of theMadras Corporation in 1898. The building was designed in the Indo Saracenicstyle by RE Ellis and was constructed by A.S. Aiyar.

The structure was later razed to make way for the new Chennai Suburban Railwayterminus and reservation centre. This multi-storeyed building also houses theoffices of various departments of the railways. The demolition of the market andPeople's Park is considered to mark the beginning of heritage activism in the city.

At present the building has 10 floors with 1st and 2nd floor as Passenger ReservationSystem (PRS). Total builtup area is 15,956.06 square meters including airconditioned area of 4176.93 square meters.

309

Energy Consumption:

Specific energy consumption comparison chart has been plotted which shows thedecrement of 10.5% in financial year 2015-16 with respect to financial year2014-15.

Description of energy conservation measures:

Various energy conservation measures were undertaken to reduce the specificpower consumption at MMC building. Major energy conservation measures arelisted below.

1. Project 1 - Utilization of LED lights

1707 nos. of LED lights of various wattages have been provided in various locationssuch as passenger circulating area like PRS and offices. The replacement of thoselights which work round the clock were targeted for replacement to enablemaximum savings.

2. Project 2 - Judicious usage of air conditioners

3 nos. of 109TR high capacity centralized air conditioning plants are being used forconditioning the PRS and its servers. One plant had to be run exclusively during theoff load hours, i.e. between 00.00hrs. to 04.00hrs., just to condition the PRSserver room. To avoid this wastage of energy, the high energy consuming 109TRChiller plant is being switched off from 00.00hrs. to 04.00hrs. and instead 4 nos.of split AC plants are being operated to enable energy conservation.

310

3. Project 3 - Judicious switching off of passenger lifts.

The MMC building is equipped with 6 nos. of lifts, i.e. 3nos.on the east side and 3nos. on the west side of the building. During non-peak hours, judicious operationof lifts is being done to conserve electrical energy i.e. during day only 4 nos. of liftsare operated and during night 2 nos. are being operated during non-peak hours toenable energy conservation.

4. Project 4 - Utilization of star rated air conditioners.

47 nos.of non-star rated window air conditioners in the building have been replacedwith energy efficient 4-star rated air conditioners.
