7. WHAT IS HIGH SPEED RAIL?
As per UIC definition, trains running at speed of
200 kmph on upgraded track and 250 kmph or
faster on new track are called High Speed
Trains.
These services may require separate, dedicated
tracks and "sealed" corridors in which grade
crossings are eliminated through the
construction of highway underpasses or
overpasses.

Comparison of HSR System in the world
11. Commercial vs Social
• Railway has social obligation to run transport service
for all the area of country irrespective of profit
motive. It can not close uneconomic lines
• It can not increase fare due to adverse political
impact even though high fuel cost – latest reaction
on dynamic pricing
• It has to generate enough resources for efficient
maintenance & replacements of assets on its own
12. ENERGY EFFICIENCY
High Speed saves Energy Costs and reduces Greenhouse Gases

13. LAND REQUIREMENT
A HSR-line allows more passengers than an six lane highway per hour
Elevated rail corridors reduce the hassle of Land Acquisition.
Land requirements are Smaller

14. DECONGESTION AND CAPACITY ADDITION
High Speed Rail Motorway
Double Track 2x3 Lanes
12 Trains per hour per Direction 4000 Cars per hour per direction
1200 Pax/Train 2.0 (Average) Passengers per car
Capacity = 14400 Passengers
per hour
Capacity = 8000 Passenger per
Hour
Reduction in commuting time between cities and
added capacity gives an excellent opportunity for
decongestion of the mega urban centers and growth of
smaller towns and other cities.
15. Increasing Urbanization
The major challenges faced are:
Major Urban centers are severely
congested:
Dramatic growth in vehicle
ownership in the past
decade.
Accessing jobs, education -
becoming increasingly time-
consuming.
Billions of man-hours are
lost with people stuck in
traffic.

16. Explosion in Inter City Travel
India’s urban population - 285 million
reported in the 2001 census and 377
million in 2011 census.
McKinsey Global Institute (MGI)
projects - 590 million by 2030 (40%
of India’s total projected population).
Increasing Urbanization
The rapid urbanization in the country
has triggered a growing demand for
inter city traffic between metropolitan
cities and 2nd and 3rd tier cities.
In absence of HSR, passenger traffic
of Airlines/ Car users is growing at 15-
20%

Journey time for air travel involves travel to airport, away from city centers and waiting
time at Airports. Distance between DELHI to CHANDIGARH is 245 Km.
19. HSR is energy efficient and is less polluting than Road/Air travel.
India imports about 80% of its oil requirement. HSR will use indigenous
energy resources like thermal/hydel/nuclear based energy
Economically as well environmentally, Rail based Transport
system is ideally suited for India.
NEED FOR HSR IN INDIA
20. Introduction of
TGV service in
1981-83
Evolution of first Class rail traffic in France
Before and after opening of the first HSR line
Existing long distance rail services have difficulties
in competing with road and air modes of transport,
The new HSR lines can stop the decline of the
railway’s share on the long distance transport
segment along those corridor.
It provides an attractive transport offer in terms of
reduced travel times and comfortable journey.
Despite the high investment cost it is economically
sustainable and need of the hour.

HSR Project(s)
(5) Land Acquisition
(3) Economic &
Financial Viability
(7) Selection of
Technology
High Speed Rail
Development
(2) Selection of
Project Corridor(s)
(6) Policy Framework
30. (1) POLITICAL WILL
Each HSR corridor will have a long gestation period and
will be highly capital intensive, so, strategic thinking is
required at the Apex level for implementing in a
programmed manner
Coordination among Central Government Ministries, State
Governments and Government Agencies
Success stories- National Highways, Airport
up-gradation, Yamuna express-way
31. (2) Selection of Project Corridor(s)
for Implementation
Vast country – Many potential corridors - Selection of
pilot Project;
Economically/financially viable projects to be given
priority;
Willingness of local governments to participate in the
project by way of land and funding support.
32. (3) Economic & Financial Viability of the
Project
High capital cost will impact viability
HSR will be a dedicated line; High demand risk due to
higher tariffs as compared to conventional rail.
Emphasis on other alternative revenue sources like Real
estate revenues, carbon credits, cross-subsidy from road/air
travelers.
33. (4) Financing of the Project(s)
The high capital costs of HSR makes it a financing
challenge.
GOI may not fully fund the corridors.
Most state governments will have to raise finances by
extra levies, real estate etc. even for part funding
Private sector may not have adequate financing
capability to fund the large HSR projects. Proper project
structuring by unbundling the projects into smaller
packages may be essential.
Funding by multilateral and bilateral funding agencies
34. (5) Land Acquisition
Critical due to stringent alignment requirements
HSR corridors pass through conurbations or sensitive
land;
Strong public protests adversely affecting large number
of projects.
Mix of alignment choice- grade/ elevated/ tunnels
35. (6) POLICY FRAMEWORK
Robust policy framework for:
Seamless implementation of projects
Assurance for attracting International investors
Creation of National High Speed Rail Authority
36. (7) Selection of Technology
Choice of Technology:
A) Fixed Infrastructure:
Mix of Embankment/Elevated/ Underground Structures and
their dimensional control;
Construction Gauge;
Fencing of the complete track/elevated track;
Electrical Installations.
B) Fast Upgrading Technology
Rolling Stock

The rolling stock for the
TGV lines is procured
by SNCF and is funded
through lease
commitments
39. TGV, France
In addition to borrowings, the TGV lines have also been developed with grant
funding from local sources. Funding pattern for three TGV lines are:
Funding by Source TGV Est East Rhine Rhone Brittany loire

Concession model Partnership contract
► Rail operators pay an
access charge based on
their actual use of the
infrastructure
► Demand risk lies with
the concessionaire
►RFF pays a rental or
availability fee based on
the performance of the
private sector partner
► Demand risk remains

Note:- S.N. 2 to 7 are the studies of Diamond Quadrilateral of High Speed Rail Network
50. The best option & main features :-
This alternative is the longest one (1,565 Km)
Alternative D is the best one in terms of Investment and Territorial
Structure, and the second one in terms of Environment
This alternative is the one with more commercial stops (17) which
determines the number of passengers available along the corridor
In terms of “social benefits”, alternative D is the one that allow more
benefit impact in the society (less cost per kilometre and more
demand)
52. Implementation Options
Considering the case studies, following could be the
implementation options
Non – PPP Option: The project are implemented by the
Government on EPC basis
PPP Options
Option 1: Design, Build, Finance, Operate and Transfer
(DBFOT) of the entire project by a single Private Developer
Option 2: Unbundling the project into different components, so
as to make the project components attractive to private players
from the perspective of affordability in terms of size and risk
allocation:
B&T (Fixed infrastructure)
DFOT (Train operations)
53. Implementation Options
Whether project is implemented through PPP or partial
Government funding route, pre-construction activities should
be started in a programmed manner – Government guidelines
MOR has already created a company named High Speed Rail
Corporation of India as a subsidiary of RVNL.
MOR has further created company called NHSRC for
implementation of Mumbai-Aahmedabad High Speed Railway
Corridor
54. Funding Options

64. Total Design Management
HSR is an integrated system, composed of Hardware, Software and Human-
ware, and factors affect each other.
Total design management, aiming at overall optimization, Ultimate safety,
Reliability, LCC and Environmental friendly, is essential.
Safety is the top priority for HSR.
Not only Construction cost but also O & M cost affect success of HSR.
Overall optimization can minimize necessary structure and facilities and
reduce total life cycle cost.
The key is appropriate interfacing on the entire HSR system with technical
standards and human resource development.
66. Project Cost :- Mumbai – Ahmedabad (Sabarmati)
Project Cost per KM = 1,312 billion JPY/508.5 KM = 2.58 billion JPY/KM
Project cost per KM = 709 billion INR/ 508.5 KM = 1.40 billion INR/Km
Assumptions:
1) Construction period is assumed as seven (7) years from2017 to 2023.
2) Escalation in capex cost during Construction period: 60% of WPI Inflation forecast.
A WPI forecasts by IMF is 6.2% per annum.
3) IDC is calculated with option 1(Public Sector + ODA) case.

79. • This is a 380 kms of high speed construction site between Jinan to
Shedong. 86% of the corridor is elevated with viaduct and
remaining are either tunnel or embankment with BLT. A typical pier
is having 8 piles with 40 m depth. Casting of girders are done in
casting yard which are generally located 15 kms apart. Casting yard
is spread over 7 hectares and production rate is 2 girders per day.
One typical girder weighs 180 T having a span of 31.5 m.

In Spain there is a provision of refund of 100% fare if the
train is late by more than 5 min. In this case destination was
about 5 kms and only 5 min was left to reach platform at
destination. European Rail Traffic Management System
(ERTMS) is normally available for High Speed route to take
care of such eventuality. In this case it was about to be
provided in next few days. The conventional system AFSA by
Dymetronics was discontinued only few days back and the
new system ERTMS was not in place. The driver was under
pressure to reach destination within the permitted time and
Technology was not there to check and control. It seems to
be Human Error with System Failure and gives a feeling ….
