Total Underground length = 14.300km
Total Alignment length = 23.085km
 Corridor 2
Break-up of alignment length
Alignment length is 22.000 km from dead end to dead end

22. Technical Inputs
• GEOTECHNICAL INVESTIGATION
 A total of 75 Boreholes were carried out along the corridors.
 Archeans rock, found in the peninsular region are generally composed of granite and
Gneisses of Peninsular Gneissic Complex, composition of duke is mainly Doleritic
whereas sedimentary formations are mainly of shale and sand stone with or without
fossiliferous beds.
• UTILITY DIVERSION
Following engineering items have been studied and described in this chapter:
 Existing utilities and planning for their diversion during construction, if necessary.
 Land acquisition necessary for the project both on permanent basis as well as
temporary, including its break up between Government and private ownership.
Details of utility provided in the report are based on information provided by utility
agencies and need to be physically verified before taking up construction work.

23. Technical Inputs
• POWER SUPPLY SYSTEM
 Broad estimation of auxiliary and traction power demand is made based on
the following assumptions:-
I. Specific energy consumption of rolling stock – 70KWh/1000 GTKM
II. Regeneration by rolling stock – 20%.
III. Elevated/at –grade station load – initially 200KW, which will increase to 300 KW
inclusive of Property Development loads in the year 2026.
IV. Underground Station load – initially 2000 kW, which will increase to 2500 kW in the year
2026.
V. Depot auxiliary load – initially 2000KW, which will increase to 2500 KW in the year 2026.
• SCADA SYSTEM
I. The entire system of power supply (receiving, traction & auxiliary supply) shall be
monitored and controlled from a centralized Operation Control Centre (OCC) through
SCADA system. Modern SCADA system with intelligent remote terminal units (RTUs)
shall be provided. Optical fibre provided for telecommunications will be used as
communication carrier for SCADA system

24. Inputs Other Than Technical
• Maintenance Depots:
 Two depots are proposed in phase-I. The Koyambedu Depot-cum-Workshop
will be the main depot and located on corridor 2. the second depot is at
Minambakkam on corridor 1 for stabling & inspection.
• Train Operation Plan:
 Salient Features of the proposed trains operation plan are :
 Running of services for 19 hours of the day (5 AM to Midnight) with a
 station dwell time of 30 seconds,
 Make up time of 5 -10% with 8 -12% coasting.
 Scheduled speed for these corridors has been assumed as 34 Kmph.

25. Inputs Other Than Technical
Total 184 coaches (92 coaches for Corridor 1 & 92 coaches for Corridor 2) are
required in the year 2011.

26. Clearances and Commitments
• Implementing a metro project in a congested metropolis is indeed a challenge.
• In sheer size, magnitude and technical complexity there are no parallels to metro
• projects. Further, these projects are to be carried out in difficult urban
environment without dislocating city life, while at the same time preserving the
environment.
• The project involves integration of a number of complex technical systems – some
of these technologies used in these systems are totally new to the country – each
one of which is a major project by itself.
• Interfacing various system contracts is a difficult and highly skilled exercise.
• Side by side, timely and adequate funds have to be assured for implementation
and lands, without encumbrances, have to be taken possession of in time.
• Clearances from the local authorities have to be taken permission to cut trees,
diversion of utilities, management of road traffic, etc., all of which will call for an
efficient and competent project implementing agency.
• Eg. Land Use Policy etc.

27. Approvals
 Government of Tamil Nadu have approved in
principle the two initial corridors on 7-11-2007
 Government of India have approved the
Chennai Metro Rail project on 28-1-2009.

28. Cost Estimates
• Capital costs workout at March 2007 price level as described hereunder
 Corridor 1 Rs. 5,997 Crores
 Corridor 2 Rs. 5,106 Crores
(Note: Under the ‘Fully Underground’ considered at one stage as per State
Govt.’s request, the cost of Corridor I was Rs. 7408 crores and Corridor II was
Rs. 7978 crores which was considered unviable.)
Costs are excluding taxes and duties, but including general charges @ 5% on
all items except land and 3% contingencies on all items.

29. Year Wise Investment
Figs in Rs. Cr
FY Without Taxes & Duties With Central Taxes Only
2008-09 533 570
2009-10 2971 3279
2010-11 3080 3484
2011-12 2705 3096
2012-13 1544 1767
2013-14 1621 1853
2014-15 613 701
Total 13067 14750
The staff is assumed to be provided @ 45 persons per kilometre. The escalation
factor used for staff costs is 6% per annum to provide for both escalation and
growth in salaries.
The cost of other expenses is based on the O & M unit cost expected for the
Delhi Metro Phase-1 project. The rate of electricity assumed in the Delhi Metro
study is about Rs. 2.30 per unit whereas at present in Chennai the applicable
rate is Rs. 3.00 per unit. The latter has been used for all calculations. The O&M
cost (excluding staff cost) has been obtained by providing an escalation of 5%
per annum.

30. Financing Plan
• Funding Patter based on SPV model is selected as represented below:
• This project which is termed as a social project is implemented and operated
under a SPV owned by Government of Tamil Nadu (GOTN) and Government of
India (GOI)

31. Revenues
• The Revenue for Chennai metro mainly consists of fare box collection and other
incomes from property development, advertisement, parking etc.
Year Corr 1&2 Trips Per Day (In lakhs)
2013-14 6.66
2016-17 7.75
2026-27 12.87
• The growth rate for traffic is assumed at 5.2% per annum
• The trip distribution has been worked out by considering average lead of 8.33 KM
and with an assumption that maximum lead is 30 KM, The graphic presentation
of the same is placed below.

32. Fare Structure
• The metro fare obtained by multiplying the bus fare by 2 times has been rounded
off to the nearest rupee.
• Other Sources of revenue:
 Development of Property
 Leasing of Parking Right at the station
 Advertisements on viaducts and many more……
