The document describes a new sky bus transit technology that could provide eco-friendly public transportation for crowded cities. The sky bus travels along roads elevated on columns, avoiding issues like derailment that affect current metro rail systems. It uses a concrete box structure held above the road on columns to guide powered bogies carrying suspended passenger coaches. This sky bus technology claims to offer safer, less expensive public transit that could be implemented more quickly compared to traditional rail. It is currently being considered for implementation in several major Indian cities.

3. The sky bus technology offered by Konkani 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. “ 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. The present Railway Technology used in metros, suffer from a
fundamental technology defect of derailment and separation
of travelling coach from the railway track, falling down on the
ground killing people.
Sky Bus is an improved Railway Technology,
eliminating the problems of existing metro rail systems
like derailments, collisions, capsizing and crushing
people, which they suffered for decades.

6. In the Sky Bus technology, the median in the middle of road
is used to raise columns to support 9.4 m wide concrete box
2.4 m high, which houses sky-guides and a powered bogie and
can run on the sky-guides at speed up to 100 kmps.

The Sky Bus travels along the road, but at
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

11. 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).

12. The typical structural configuration of the skybus railway
consists of 1m dia concrete columns about 9m tall, spaced
about 10-15m apart supporting a continuous box structure
about 9m wide, cantilevering equally on both sides of the
columns.
These cantilevered portions of the box structure has got a
continuous slit through which the passenger cars are suspended
from the bogies above, running on the rails which are
concealed in the box. These columns are usually placed in the
median space of existing roadways, thus enabling the skybus
route to follow existing road pattern.

13. •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.
13

14. 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.

15. Suppose a standard railway coach
running on a railway track…
The under frame with standard
railway wheel – set running on a
railway track…
15

16. The under frame remains the same,
railway wheels run on the same track,
coach is firmly attached to under frame
positively.
The under-frame with wheels and railway
traction motors & railway track enclosed
in the concrete box- travel on the railway
track , carrying the coach below outside
the concrete box- now the coach and the
track are positively held together- cannot
escape from rails!

17. 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.
In conventional railway wind can topple the trains. In Sky
Bus wind cannot topple- there is positive link between the rail
guidance system and the Bus Coaches- with 400%.

18. 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.

19. In Madurai, from thiruparangndram to avaniyaburam
via tvs nagar-south gate-east gate-anupanaditheppakulam.
And from simmakal to koodal nagar via periyarsouthgate-east gate-thamukam-court-maatuthavanisurveyor colony-ayyarbangalow-aanayur.

20. 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 of double line route, including
rolling – stock and train control is Rs. 50 crores.
The energy in Sky Bus, is used to carry more people than in
Metro Rails, which carries more dead loads.

22. 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.
