The document discusses the Sky Bus technology, a proposed new mass transit system that would provide urban transportation. Some key points: - Sky Bus claims to offer a safer alternative to existing metro rail systems by addressing issues like derailment. It works by transferring the load to a skyway structure if the wheels fail or get obstructed. - The skyway would consist of a continuous concrete box structure about 9 meters wide supported by 1 meter diameter columns spaced 10-15 meters apart. This would be constructed about 9-10 meters above road level. - Proponents argue Sky Bus could be built more quickly and at 50-75% lower costs than conventional metros since it would not require heavy coaches and could

3. INTRODUCTION
 The sky bus technology offered by Konkan railway
corporation . It redefine the thinking and planning for
urban transport being a eco-friendly.
 It is the patented technology developed for new
millennium and will cause a paradigm shift in urban
transportation all over the world. .

4. SKY BUS
“A unique mass transit system which than can be put
up within any two years in any crowded and
congested city for safe transportation without loss
of time.”

5. Why sky bus is safe

The present Railway Technology used in metros- defect of
derailment.

Sky Bus- eliminating the problems of existing metro rail
systems like derailments, collisions, capsizing and
crushing people.

Compared to conventional railway systems, the centre of
gravity of the mass being carried on the wheels is brought
down to be closer to the wheel support. Hence dynamic
safety is many times improved.

7. Working Principle of Sky Bus
•As long as the wheels are on the
rails, the coach runs.
•But failure of rails / obstruction
by a heavy wind force may create
dangerous situations.
When the wheels climb 25 to 30
mm flange, then derailment occurs.

8. Cont..
If derailment occurs, then there is
nothing to hold the coach, then the
coach just topples .
Such falling of coach can kill people
inside the coach and also people on
the road, if any.

9. Evolution Of Sky Bus Technology
Suppose a standard railway
coach running on a railway
track…
The under frame with standard
railway wheel – set running on
a railway track…

10. Structural Link
• There are two possible ways of doing this:
 The First Concept, The Load Can Be Transferred From The
Platform By A Tensile Member, the load can be transmitted by
a portal frame.
 The Second Concept Allows For More Freedom In
Configurations But Is Less Efficient As It Results In High
Bending Moments.
 . The Sky Bus Coach Was Designed For Various Specified
Loads Including This Condition And Analyzed Using The
Finite-element Method (Fem).

11. Technology Of Sky Bus

The median in the middle of road : 9.4 m wide,2.4 m high

The typical structural configuration :
 1m dia concrete columns,
 9m tall,
 spaced 10-15m apart supporting a continuous box
structure about 9m wide,
 cantilevering equally on both sides of the columns.

Sky way It consists of a concrete box structure 8.4*2.4m.
Carried over a series of piers at height of 9-10m above the
road level.

In middle roadway it supports by pile foundation about 1m
depth. There are no points and crossings.

12.  Performance
 Safety
 Land & Protection to existing buildings
 Capital and running costs
 Construction
 Charges
 Financial viability

13. Why Sky Bus saves 50% to 75% in costs
 Conventional railway provides for heavy steel
coaches to protect people from derailments and
capsizing. So carry more steel and dead weight
instead of people.
 The capital cost per km is Rs. 50 crores.
 The energy in Sky Bus, is used to carry more people than
in Metro Rails, which carries more dead loads.

14. Proposals For Establishing Sky Bus
 The authorities in Mumbai are sufficiently taken up
with the idea to consider setting up a sky bus system
on a 9.8 km stretch between Adhere and Ghatkopar.
 To the Tamil Nadu Government, has presented a
possible route network between Muthialpet in North
Chennai to Tippet in the west — via Koyambedu —
and Mahabalipuram 45 km South of the city.
Konkani railway corporation would soon begin work
on construction of a 1.6 km running track of Sky bus in
Goa.

15. Conclusion
 This research confirms that the advantages of sky bus
technology are tremendous. For overpopulated Indian
urban areas, sky bus seems to be the best solution for safe,
quality, and inexpensive mass public transportation.
 Indian state governments and metro city corporations are
waiting for final approval from experts. If sky bus project
receives approval by experts for its track tests, sky bus
will become the solution for urban public
transportation in 21st century, at least for India.
