PREFACE
Since the release of Praja-RAAG’s “Call to Action Report on Suburban rail service for Bengaluru” in
August 2010, there have been several developments on its advocacy campaign front. The campaign for
‘Suburban Rail Service in Bengaluru’, aka, Namma Railu, has been enriched with continuous discussions
on its importance, socio-politico-economic analysis and regular coverage in the media. In July 2012,
RITES submitted its 2012 RITES report on “Implementation of Suburban rail service in Bengaluru”,
endorsing the need and demand of citizen groups for suburban rail service in the city. This was followed
by several high level interactions among the urban development departments of Karnataka Government to
consider the proposal and accord the necessary approvals at state government level.
In July, 2013, the Chief Minister of Karnataka finally gave the in- principle approval to the Namma Railu
Proposal. In October 2013, finally, DULT (Department of Urban Land Transport), GOK, sent a formal
proposal to Ministry of Railways for its approval and participation in the Special Purpose Vehicle (SPV).
The project since then is waiting for railway’s approval and implementation thereof.
This report is a collection of various data, analysis and reports on ‘socio-economic and environmental
impact of Namma Railu. These reports have been published on Praja-RAAG website @ www.praja.in at
various points of time during this campaign since its beginning in 2010.
It is our hope that readers of this report will be able to easily grasp the information presented and be able to
comprehend the socio-economic and environmental benefits of Namma Railu service in Bengaluru.

1 Introduction
Provisioning mass transport for the growing economy has never been so much of a priority before. With the
kind of visibility Bengaluru has in the international arena and the role India is going to play globally, it is
important for both central and state governments to sit up and take note. Ignoring long-term mass transport
needs for the city can result in grave consequences. The economy of any city thrives on availability of good
quality labor at affordable cost. Expensive housing and increased travel times can result in severe pressures
on productivity from human capital. This may ultimately lead to flight of capital and hurt the economy with
cascading effects.
Housing has already become unaffordable in Bengaluru for the lower and middle class, which form a major
portion of the workforce today and also in the long-term future. The industrial towns around Bengaluru are
close to existing railway tracks. These tracks can be said to lie wasted to some extent since a viable mass
transit option is not seriously considered. No amount of connectivity within the city will be enough if that
connectivity is not supplemented by mass transit to these nearby industrial towns. The key is thus frequent,
low cost connectivity which can be achieved by utilization and enhancement of the existing train tracks
between Bengaluru and the many growth centers in the suburbs and towns around it. Multiple reports over
twenty seven (27) years including many RITES survey reports have drawn attention to discuss this fact
repeatedly but with little action and follow-up.
1.1 The Need
Per McKinsey report on India’s urbanization by 2030 will be as follows:
 590 million people will live in cities, nearly twice the population of US today
 270 million people will be the net increase of working age population
 70% of net new employment will be generated in cities
 91 million households will be middle class, up from 22 million today
 700-900 million sqm of commercial & residential space needs to be built, or a new Chicago
every year
 2.5 billion sqm of roads will have to be paved, 20 times the capacity created in the past decade
 7400 Km of metros & subways will need to be constructed, 20 times the capacity added in the
past decade
Bengaluru is a leader in this growth. Per the report, it will have more than 10 million people inhabiting it
by 2030, of whom a majority will be from the middle and lower income group. For them, the urban
mobility challenge will only increase as the working population increases and hence, commute will
become a major quality of life indicator.
Further, research by Center for Ecological Sciences, IISc, reveals a 76% decline in vegetation cover and a
79% decline in water bodies due to the increase in built up space in the urban areas of Bengaluru. This
implies that any further significant net addition within the urban area will result in a decline in standard of
living.
How Bengaluru builds its infrastructure & manages this growth will determine if it will continue to lead in
taking the country forward or it will become a failure leading to urban chaos.

1.2 Growth Center paradigm
CTTP 2007 commissioned by KUIFDC/IDD of GoK had this to say regarding Commuter Rail on existing
tracks: “With the development of the huge Multiple Economic Activity Areas like Electronic City, I.T.
Parks, Industrial & Commercial Areas with consequent job opportunities on the one hand and availability
of comparatively cheaper accommodation in surrounding towns like Hosur, Ramanagaram, Tumkur, etc.
where a large number of working population is likely to live, substantial commuter movement between
these towns and the Metropolis will take place.”
One critical element of this urban operating model of the future is how cities will make and enforce land &
space choices. Housing has already become unaffordable in Bengaluru for the lower and middle classes.
No city in India has allocated space and zoning for affordable housing. The housing market has a
preference to locate close to commercial/urban spaces to increase the premium the houses can fetch. This
increases both, the cost & mixed use urban sprawl. Counter magnet cities, with suburban mass transit, are
the best and most effective way to focus on affordable housing for middle & lower income groups who
will constitute 75% of the future workforce. Nearby suburban towns were often viewed as best options for
setting up industries to release growth pressures on the city to absorb new migrants and to relocate some
people from the city. It never happened, because a business ecosystem cannot be artificially replaced or
relocated. These suburban cities need to be zoned to take the housing pressure off Bengaluru and this can
happen only when the option of traveling to Bengaluru quickly and cheaply becomes a reality.
From the McKinsey report one can gather that, for the first time in India’s history, Karnataka along with
other large south Indian states will have more people in its cities than in its villages. This means that the
pressure on cities will increase considerably in the future to avoid urban sprawl and still manage their
growth. Increasing the area of Bengaluru and making it Bruhat Bengaluru has put undue pressure on civic
bodies and made the area difficult to manage. The alternate model is to enable suburban cities to
become more attractive destinations for settlers & connect them via mass transit trains to within an
approximate one hour commute distance from Bengaluru.

In the past two decades the state government in co-operation with the central government has attempted a
few options to address the urban transportation challenges. Namma Metro, Mono Rail, High Speed Rail to
BIAL, rejuvenated BMTC service are all examples. While most of this focus on making commute within
Bengaluru city easier, the suburban connects is what will bring dividends in the long run.
Efficiency in operations, more advanced levels of automation in signaling supplemented by close
coordination with local authorities in implementing last mile solutions and superior interchange with metro
are going to determine the success of the Commuter rail.
The rest of this report will provide the excerpts from Praja’s ‘Call to Action Report for Bangalore
Suburban rail service’ report of 2010 and 2012’s RITES technical feasibility report recommending
suburban rail service in Bengaluru along with socio-economic indicators buttressing the demand for it.
1.3 Namma Railu - What is it?
The suburban rail service for Bengaluru, aka Namma Railu, is a proposal for daily train services
connecting suburban growth centers within an approximate one hour travel distance to Bengaluru. It is a
proposal for running suburban rail service with environmental friendly electric trains which are bicycle &
disabled friendly, operating on existing tracks, doubled or quadrupled as necessary, for operation at a high
frequency of 20 or more trains per day between each origin-destination pair.
1.4 Growth centers
The growth centers indicated in the map as green are the towns which will be connected by the Commuter
Rail. These growth centers are significant because they are currently not very heavily populated despite
their close proximity to Bengaluru. They have sufficient headroom for growth and are approximately
within one hour traveling distance from Bengaluru. The catchment areas in between have the potential to
grow with suburban rail services.

About 1/3rd
of this population are not served because of lack of stations and last mile within local areas.
These 33% consequently move to other modes like private transport to fulfill their commuting needs,
putting further pressure on roads.

2 Socio-Political Considerations
If one were to talk of socio-political benefits of proposed Namma Railu / CRS service, volumes can be
written on it. Since the objective of this document is to illustrate the highlights of benefits that suburban
rail service can bring in, only handful of the benefits are discussed in the following sections. The purpose
is to drive home the point that as every public utility project, as a public mass transit system, proposed
project is also full of socio-political benefits.
2.1 Moving growth beyond Bengaluru
The Bengaluru city for both good and bad reasons has reached the saturation point for any type of growth,
be it economics, population, industries or commerce. The result is seen in terms of rationing of power and
water. Housing has become expensive and proving to be a determining factor for availability of cheap
labor. It is time the growth in Bengaluru city and its suburbs was put on leash. It is time to pursue policies
and programs to shift the development and growth beyond Bengaluru. Nothing can be better for this
purpose than provisioning of Namma Railu, CRS to connect the towns of Mandya, Ramanagaram,
Tumkur, Doddaballpur, Chikballpur, Malur, Hosur and Bangarpet.
With the reliable suburban rail service, opportunities will open up in these towns for
 affordable housing
 cheap land for starting industries and businesses
 transportation of goods and products from and to Bengaluru and beyond
 opportunities to reside in towns and work in Bengaluru
 space for setting up new educational, research, health and sports institutes.
2.2 Reach and its coverage
Per RITES, there is a potential for 440 KMs of CRS network in the above BMRDA region. This network
spans across
 8 Loksabha Constituencies in Karnataka:
o Bengaluru Central
o Bengaluru South
o Bengaluru North
o Bengaluru Rural
o Chickballapur
o Kolar
o Tumkur
o Mandya
 47 Assembly Constituencies in Karnataka
o Benefiting 48 Million people in the catchment areas
o Garnering 30% of the public transport trips, i.e. 2.97 million
o Supporting 2 million commuters per day, an increase from 1.5 lakhs at present.

2.3 Profile of the Benefiting Population
The proposed CRS network touches all sections of the society. Its inclusiveness is not something made-up,
but comes with its turf.
 Out of 440 Km, 220 Km fall in urban areas and 220 Km in rural areas
 It reaches city central, suburbs, semi-rural and rural areas equally
 With right kind of rakes, ticket pricing, stops, it is guaranteed to attract all sections –
o Poor to Rich
o Office goers to industrial workers
o Urban dwellers to rural folks
o Students to senior citizens
The closest match by any other mass transit system comes from Namma Metro which is under
construction. Namma Metro is designed and built for commute inside the city and by its design excludes
certain areas, population, etc. In recent trends for reasons of profiteering, the present mass transit systems
providers like BMTC in the city is resorting to serving the affluent class more and neglecting the other
sections. That goes against the very purpose of public mass transit system, which must provide the
balanced connectivity across all sections and all regions.
Proposed Namma Railu Projectin comparison is well-placed to serve all sections and across all regions in
the BMR region. It is the best avenue of providing access to affordable mobility. The consequences of this
emphasis are explained in the subsequent sections in detail.

2.4 Comparison with similar mass transit systems
The closest comparative mass transit systems in Bangalore at present are, under construction ‘Namma
Metro’ along with some proposals for Monorail, LRT and HSRL which are before the state government.
Here are some comparisons in terms of network length and capacity.

2.5 Social, Economic Empowerment
Given its reach and impact on its beneficiaries, Namma Railu Project can also be proudly projected as
empowerment of socially and economically backward sections of the population both in urban and rural
areas of the Bengaluru region.

 Empowerment due to reliable and faster access to centers of education, health care, recreation,
industries and business
 Nothing short of poverty alleviation project, but in more sustainable form
2.5.1 Social Empowerment
For decades Bangalore has been known for educational and health institutes not limiting to famous IISc,
IIM-B and NIMHANS alone. After 1980’s liberal policy of state government to open up the education and
health sector to private entities, the whole of Karnataka witnessed a kind of revolution in higher
educational institutes in every town and city. Needless to say the number of higher educational and
medical institutes that have come up in the past 3 decades in Bangalore and its surrounding areas
especially in the proposed CRS catchment areas. The above map illustrates a handful of them.
Proposed CRS is well-placed to provide the mass transit connectivity to these centers of education, health
and employment. In general it will not be wrong to say that it would empower the people living in the city,
suburbs, villages and towns with affordable mobility to
 access educational institutes especially those offering professional and higher education courses.
 access vocational training institutes to get trained in technical and semi-technical skills.
 access personality development training institutes including finishing schools for leadership
training.
 access health and medical institutes for better and quality treatments.
 access markets and business centers.
 access various pilgrimage and tourist centers that lie inside and outside Bangalore city.
 access government departments and agencies for citizens’ services like processing passports
applications, ration cards, driving permits, etc.

13. Soci0-Economic & Environmental Impact of Namma Railu
12
2.5.2 Scope for Poverty Alleviation
CRS in particular has the potential to help people in lower economic strata to climb the economic ladder
and come out of the condition they are in today. Affordable mobility to access education and employment
will open up the avenues of work and business. Lower labor rates will enhance the prospects of newer
businesses and newer jobs. Newer jobs mean more opportunities for work and earnings.
The profile of population in the CRS catchments, especially outside Bangalore, is mostly rural, agricultural
and poorer to a large extent. With the provision of CRS, there will be an opportunity to these sections to
access better avenues be they for education or for employment.
2.5.3 Economic Empowerment
It is a known fact that, in general, social empowerment will lead to the economic empowerment. The
improvement in literacy levels will boost the prospects of higher personal earnings and economics of the
locality. In the context of CRS, economic empowerment from greater affordable mobility access is well
recognized across the world. The proposed Suburban rail service will
 enable people to seek employment away from home.
 provide industry and business with labor with economic and affordable mobility.
 help reduce unemployment, hence reduce and prevent social problems.
 provide people an opportunity to afford a low cost housing in towns but still be able to work in
Bengaluru.
 stimulate economic growth in adjacent towns and catchment areas resulting in lifting the standard
of living.
 help people make more trips seeking health care services, shopping and looking for recreation.
2.6 Impact of affordable daily commute service
Using a socio-economic study done for public transit in the state of Wisconsin, USA, we can study how
the absence of affordable public transit system would impact the transit choices for the people, especially
those who live beyond urban sprawling. Here is a sample of that impact.

3 Economics and Return on Investment
In the era of market economy, there is absolutely no chance or room for any projects to be considered only
on basis of social good. These days government officials, entrusted with approving such projects are
scrutinizing them for economic impact, taking into account the investments needed and returns CRS will
accrue in coming years.
Namma Railu proposal is also going through such close scrutiny in government corridors on its economic
viability. This is what the Principal Secretary at UDD (Urban Development Department) had to say about
their due diligence on according approval to Namma Railu proposal:
.
It is well-known that investments into any infrastructure projects especially in the public mass transit
systems, is always a profitable venture. Not sure if the officers in GOK had enough time to ponder upon
the economic benefits of Namma Railu so that their job becomes a little easy and see fewer roadblocks in
approving the project.
Here is an attempt to bring out the economic benefits that Namma Railu will bring in with its introduction
in the region. Hopefully, these will not go unnoticed in government, political and public corridors.
3.1 Cost of building Namma Railu
Per RITES, the cost for building and making Namma Railu operational will cost in the range of 8000-9000
crores. Though this is a significant amount comparing with cost of building it with other mass transit
system provides an insight into cost and output comparisons. Here is a comparison of construction cost of
CRS with other planned mass transit systems in Bengaluru:
CRS* Metro* Monorail ∏ HSRL ∏
Daily Ridership 20,00,000 10,50,000 1,50,000 30,000

Construction Cost
(Per KM) (Crores)
15-20 200-400 150 180-200
"...Yes we are looking at it. Since this is a cost intensive project, the project requires lots of thinking
and co-ordination from various authorities and takes time. Once positive steps are taken, we
hopefully will like to forward..."
- Dr. Amita Prasad, Principal Secretary, UDD

3.3 Outcome of 8000 Crores Investment
This 8000 crores investment will not only help introduce CRS in Bengaluru but would have enhanced the
entire railway infrastructure capacity in the city by 100%. Here is a snapshot of what this investment will
do:
 Create capacity to operate CRS services - 675 Ssrvices per day carrying two million riders per day.
 Capacity enhancements at SBC, YPR, BYP, YEL - will double i.e. platforms, dtations, etc.
 Railways will be able to double the number of long distance trains it can operate and handle today.
 Enhancements to passenger amenities including ticketing counters, parking, etc.
 Latest signaling system to South Western Railway’s Bangalore division.
 ROB/RUB at every railway crossing in the CRS operational region - safety and easing congestion
due to manned crossings.
3.4 Return on Investment
It is known world over that every rupee that is invested in mass transit infrastructure will yield 6 rupees in
return. Here is a list of potential economic returns of 8000 Crores of investment in CRS:
 Total Economic Returns - 6 times of investment
 8000 Crores of investment will yield 48,000 crores in return.
 Business Sales - 3 times of investment
 Income to GOK in taxes and receipts - 1500 crores per annum
 Savings in the lieu of other PT projects – 10,000 crores
GOK's income of 1500 Crores per annum alone is more than enough to recover the cost (8000 Crores) in
five to six years.
3.5 Employment generation in construction, operations of CRS
There is no need to write about the employment generation due to activities in initial building/construction
and operation of CRS. According to ‘'The Socio-Economic Benefits of Transit in Wisconson - By HLB
Decision Economics' report,
 Every $10 million invested in transit capital projects yields 300 jobs (Direct and Indirect)
 Every $ 10 million invested in transit operations generates 600 jobs (Direct and indirect)
Given the demography of proposed CRS network, it will not be incorrect to assume similar benefits
accrual if not higher benefits.
3.6 Economic growth in adjacent towns
It is not a brainer to know the potential for catchments areas to benefit economically from CRS operations.
Trains bring industries and businesses, thereby bringing in increased economic activities in the vicinity. In
the context of Namma Railu, it is a foregone conclusion that towns of Mandya, Ramanagaram, Malur,
Bangarpet, Chikballapur, Doddaballapur and Tumkur will see the economic growth that is not seen in the
past. Economic growth means prosperity in towns. Who doesn't want it?
Major Towns Population Major Trade/Economic activity
Mandya 137,735 Rice, Sugar, Silk Rearing, Higher Educational Institutes
Ramanagaram* 79,365 Silk Rearing, Higher Educational Institutes
Malur* 27,815 Clay tile-and-brick industry, Small-scale industries, Business

3.7 Scope for upward mobility of poor and economic weaker sections
If CRS is implemented right, it will facilitate affordable access to schools/colleges, industries and
businesses thereby helping people from lower economic strata to help themselves to move upward. Greater
education means more opportunities for better jobs. Better jobs mean more monthly income, i.e.,
opportunity for greater prosperity. Looking at the potential of economic prosperity accrual due to CRS, it
is not wrong to say CRS has the potential to be a project for poverty alleviation in rural and urban areas of
Bengaluru.

4 Decongestion of City Roads
The vehicular growth in Bengaluru is going on an alarming pace with growth of 40% in last decade. Here
is a glimpse of this growth.
Year Total # of Vehicles
1981 1,90,653
1991 6,62,148
2001 15,66,142
2011 40,68,045
2015 68,82,868
2025 1,92,93,509
2030 3,22,86,085
This begs an important question; does Bengaluru have the space to accommodate so many vehicles?
Certainly Bengaluru city does not have the resources to accommodate all these vehicles. Even as of today,
all the major city roads are choked with perpetual traffic grid locks. The commute time has just multiplied
many times during these 2 decades of high growth rate of vehicles in the city. In these circumstances, any
addition of vehicles, without addressing infrastructure improvements, will only make the matters worse.
Road congestion is slowly impacting the city in many ways, one being the productivity of workers and
scope for further growth.
Like many other cities in India, Bengaluru has also reached a stage where it cannot afford to add more
congestion on its roads and slowly impact the sustainability. If this continues, Bengaluru will soon be on
fast track becoming a dead city like many others. Therefore, fighting congestion becomes paramount and
priority for state government, planners and citizens.
The solution lies in moving people not in moving vehicles if city roads are to be decongested. For that, city
needs a mass transit system to move people in large numbers. Namma Railu, aka suburban rail service,
provides that opportunity to address the congestion challenges on city roads by offering the mass transit
solution to move people in large numbers that too at affordable cost.

RITES, in its 2012 report ‘Implementation of Commuter Rail System for Bangalore’, suggests that the
project be implemented in 4 phases. Here is a summary of those phases and outcomes.
Phase Investment
(In Crorers)
No. of Suburban
Services
Commuter trips that can be
generated per Day
At Present N/A N/A 1,50,000
1A 175 24 4,00,000
1 3831 172 8,00,000
2 2251 94 15,00,000
3 2504 NA 25,00,000
It is estimated that the ratio of 2-wheelers and Cars that are now fulfilling the commuter trips is about 75-
25, i.e. for every car, there are three 2-wheelers on the road. Taking these ratios and substituting these
personal vehicle trips for the same that can be generated by having suburban rail services/CRS, this is what
it would look like:
Year Phase (per RITES) 2 Wheelers Cars Total Commuter Trips
per day
2014 Without CRS 33,75,000 11,25,000 45,00,000
2016 With CRS - Phase 1A 30,75,000 10,25,000 45,00,000
2018 With CRS - Phase 1 27,75,000 9,25,000 45,00,000
2021 With CRS - Phase 2 22,50,000 7,50,000 45,00,000
2025 With CRS - Phase 3 15,00,000 5,00,000 45,00,000
NOTE: Total commuters trips are kept constant @ 45,00,000 which is about 33% of the total daily
commuter trips.
The numbers and graphic representation of the same clearly demonstrate that introduction of
suburban/commuter rail services will certainly bring down the number of personal vehicles on city roads.
This can only mean
 fewer personal vehicles on road, i.e. inefficiency in carrying capacity /trip gets reduced.
 fewer vehicles means less congestion on roads
 lesser congestion means, fewer fatalities

 The biggest beneficiary of lesser congestion would be the public transport buses which at present
have to compete with single occupancy vehicles. This will enable them to maintain their departure
and arrival times.

5 Environmental Impact
We all know inefficiency of fuel consumption of 2-wheelers and cars in comparison to Bus and Trains.
This gets more hazardous in urban commute space.
In terms of CO2 that is emitted from different vehicles then defines the overall sustainability of the
transport system that is operated in the city. Here is a rough estimate of CO2 emissions from 2 Wheeler,
Car and a Suburban Rail System /CRS.
 2 wheeler - 26 gms of CO2 per person per KM.1
 Car - 227 gms of CO2 per person per KM
 Commuter Train - 22 gms of CO2 per person per KM
If we extrapolate these numbers for the different phases of Namma Railu, in terms of total commuter trips,
this is what it would look like
Phases Year Total KMs / day CO2 Emission
in 2 Wheelers
(in Tonne)
CO2 Emission in
Cars (in Tonne)
CO2 Emission in

2 2021 1,50,00,000 334.82 938.30 380.30
3 2025 2,50,00,000 558.05 1563.90 633.83
NOTE: Here 10KM per trip is estimated to be the average trip length. That means, for phase 1-A, a total of 40 lakh
Kms of trip length is generated.

The benefits of such an enormous reduction in carbon emissions will have a significant impact on the city,
its air quality, and more importantly, health of the people.

6 CONCLUSION
Namma Railu, aka Suburban Rail Service can be a game changer for Bengaluru city. It could help
immensely to mitigate urban transport issues besides assisting the nearby towns with growth and
development. Expanding roads or building expensive roadways between the city and nearby
towns would not address issues of air pollution or traffic congestion. Construction costs being low
(when compared with new systems), Suburban Rail is probably the best option to connect satellite
towns or twin cities within a metropolitan region owing to the many benefits that it promises.

8 Appendix – A: The train ride that was an eye opener
First Praja train ride meet report by Pranav Jha, Founder Praja.in
On the morning of May 8, 2010, five of us – Muralidhar Rao, Pranav Jha, Manjari, Naveen and Satya –
travelled on a local suburban rail to Hosur to experience firsthand the feasibility of the Commuter Rail
System (CRS). Ah! Ufff!. What an eye opener. Easily the best Praja meeting of all. I am so lost for words
here. So would be IDS, Murali, Naveen and Manjari, you bet.
There was no one around to give us our tickets at Belundur Station. But the counter opened by the time
train arrived. Six rupees per person for a ride till Hosur. IDS paid Rs 10 from Hebbal to Hosur. How much
would you be willing to pay for a comfortable smoke - and traffic-free ride from Hebbal to Hosur?
Sathya took the train from Hebbal. Naveen, Manjari and myself got on to it at Belandur station at 7:10.
Murali joined us near Sarjapur Road at about 7:20.
We were at Hosur station by around 7:50. Had our morning coffee there as the engine changed ends.
Return ride started at 8:10 am. We were back at Belandur station by 8:45 or so.
“But all in all, after watching clean and empty train, and nice little stations, all so close from the busy
corridors and suburbs of Bangalore, we were wondering why this magnificent option was underutilized
while we all debate public transportation?”
