SKY BUS

INTRODUCTION
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. .
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.”
Why sky bus is safe?
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.
Technology of Sky Bus:
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.
Components Of Sky Bus:
Sky Way
Sky Bogies
Sky Coaches
Sky Stations
Traverse arrangements at terminals
Sky Way The Sky Bus travels along the road, but at
higher level.
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

Components
Structural Configuration
Structural LinkThere 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).
Cont..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.
Working Principle of Sky Bus
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.
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.
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…
Cont..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!
Safety Measures:
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%.
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.
Cont..In Madurai, from thiruparangndram to avaniyaburam
via tvs nagar-south gate-east gate-anupanadi-
theppakulam.
And from simmakal to koodal nagar via periyar-
southgate-east gate-thamukam-court-maatuthavani-
surveyor colony-ayyarbangalow-aanayur.
Why Sky Bus saves 50% to 75% in costs : 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.
Advantages Of Sky Bus Over Other
Modes:Performance
Safety
Land & Protection to existing buildings
Capital and running costs

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.
