Metro & Railways
Delhi Metro completes 314 km
network after opening Shiv Vihar-
Trilokpuri Sanjay Lake section
Over 515 km metro rail network already operational in India and
more than 664 km of Metro Rail projects are presently under various
stages of implementation in 15 cities.
O
n October 31, the Delhi
Metro Rail
Corporation
(DMRC) opened the 17.8
km long Shiv Vihar –
Trilokpuri Sanjay Lake section of the
59 km long Majlis Park-Shiv Vihar
corridor (Line 7) of Phase 3, also
known as the Pink Line.
This stretch will be a major boon
for the eastern and northern fringes of
the
national
capital.
Three
interchange facilities at Welcome
(With Red Line), Karkarduma and
Anand Vihar ISBT (with Blue Line)
will
tremendously
boost
the
connectivity of areas such as Shiv
Vihar,
Gokul
Puri,
Maujpur,
Jaffrabad etc. In the future, this
stretch will get connected with the
presently operational Majlis Park –
Lajpat Nagar section of Pink Line.
With the opening of this section,
the Delhi Metro network now
becomes 314 kilometers long with 229
Metro
stations.
After
the
inauguration of this section, Delhi
Metro will have opened over 80
kilometers of new lines this year. All
the major corridors under Delhi
Metro’s Phase 3 are expected to be
opened for passengers by the end of
the year.
Interchange Facility on this Section
This section has three interchange
stations at Anand Vihar ISBT,
Karkarduma and Welcome. The
WWW.URBANTRANSPORTNEWS.COM
facility of interchange of Metro trains
between line 7 (Pink Line) & line 3/4
(Blue Line) is available at Anand
Vihar ISBT and Karkarduma Station
and between line7 & line 1 (Red Line)
at Welcome Station. The Maujpur
Station is a four (4) track station
having the provision of connection
from Maujpur to Mukundpur, a
corridor proposed in Phase-IV of the
Delhi Metro project.
Special Spans
The elevated section between I.P
Extension and Maujpur consists of
Special Spans including two Steel
Spans over the existing DMRC
Redline (Line 1) and Northern
Railway track between Welcome &
Shahdara.
Cantilever Construction (CLC)
Spans of lengths 255 meters over
Anand Vihar Railway Yard and
Mainline tracks were constructed over
running track with 25 KVA OHE
System.
Sharp Curves
Due to uneven twist and turns in
this alignment, Delhi Metro had to
construct as many as 10 curves on
this stretch that passes through very
congested areas like I.P. Extension,
Anand Vihar, Welcome, Seelampur,
Jaffrabad, and Maujpur.
Curves of less than 300 meters of
the radius are considered “Sharp

Curves” in Urban Rail Construction.
The work of building sharp curves
requires a lot of engineering skills and
several factors have to be kept in
mind
while
designing
special
segments/spans at the concerned
turn/juncture. DMRC had to form
especially dedicated beds in its
casting yard for the casting of special
segments. The segments were
constructed according to the already
defined ”radius of curvature” and
then put on the viaduct.
DMRC is expanding its
footprint of metro connectivity at
a scorching pace. We just
inaugurated the Sanjay Lake to
Shiv Vihar line on 31 October
2018, taking the total
operational lines to 532 km.
