2. ABOUT DMRC
• A Government Company jointly promoted by
Government of India and Government of
Delhi.
• Incorporated in May 1995, under the name
Delhi Metro Rail Corporation Ltd. (DMRC).
• The two Governments have 50% shares
each in this Corporation
• Has the responsibility for construction and
operation of Delhi Metro
w w w. d e l h i m e t r o r a i l . c o m
ADVANTAGES OF METRO SYSTEM
• Has a carrying capacity as high as 60,000 –
80,000 phpdt (peak hour peak direction
traffic).
• Requires 1/5th energy per passenger km.
compared to road – based system.
• Causes no air pollution in the city and
lesser noise levels
• Occupies no road space if underground
and only about 2 metre width of the road,
along central median, if elevated.

3. ADVANTAGES OF METRO SYSTEM
• Carries same amount of traffic as 6 lanes of
bus traffic or 26 lanes of private motor cars
(each way)
• Is more reliable, comfortable and safer than
road based system
• Reduces journey time by anything between
50% and 75% depending on road conditions

8. SALIENT FEATURES
• DMRC HAS ELECTRICAL DRIVEN MRTS
WHICH USES STATE OF THE ART ROLLING
STOCK ON ALL LINES
• THREE LINES ARE IN OPERATION (65KM) IN
PHASE-I
• COACHES ARE EQUIPPED WITH 3 PHASE
AC TRACTION MOTORS WITH
REGENERATIVE BRAKING SYSTEM

SALIENT FEATURES
THE TECHNOLOGY EMPLOYED IN
DMRC IS DIFFERENT FROM THE
PREVALENT SYSTEM ADOPTED BY
THE OTHER METRO SYSTEM IN THE
COUNTRY
OTHERS USE CONVENTIONAL
ELECTRO-DYNAMIC RHEOSTATIC
