This document discusses Skybus, an emerging transportation technology that involves suspended railway systems running on tracks above roadways. Some key points: - Skybus aims to provide safe, high-capacity public transportation without disrupting traffic below. Coaches are suspended from above and guided along tracks mounted on elevated viaducts. - It is composed of sky ways (elevated tracks), sky bogies (motorized trucks), sky coaches (passenger cars), and sky stations (elevated platforms). Coaches hold 150 passengers each and are connected in pairs. - Proponents argue Skybus could provide mass transit at half the cost of underground metros while avoiding issues like derailment, collision, and caps

3.  WHAT IS SKYBUS ?
 Sky bus is a suspended railway system, can never capsize nor collide
due to its design and construction technique .
 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.”
 The sky bus technology offered by Konkani railway corporation .
 It redefines the thinking and planning for urban transport being eco-friendly.
 Pre-fabricated latest construction technologies, which save time and money
resulting in easy execution of the project in busy urban areas without
disturbing the existing traffic pattern

5.  COMPONENTS OF SKYBUS :
I. Sky Way
II. Sky Bogies
III. Sky Coaches
IV. Sky Stations
V. Traverse Arrangements

6. I . SKY WAY
 Path in which Sky Bus travels
 Includes concrete box carried over a series of piers at a height
of about 10m above existing road level
 Two rails are appropriately fixed to guide the bus

7. II . SKY BOGIES
 Two Standard axle bogies provide the drive mechanism
 Each bogie is driven by 3-phase alternating current (AC) motor.
 Speed of 100 kmph (max. 160 kmph)
 Disc & Emergency brakes is used
 Power is delivered using brushes or by current carrying wheels

8. III . SKY COACHES
 Double walled lightweight shells with wide large windows and suspended
below rails
 Air conditioned coaches and have 4m wide
and automatic doors
 Audio visual information to passengers
 2m x 2m space for easy entry & exit
 Each coach carries 150 passengers
 Each coach is 9.25m long and 3.2 m wide
 Consist of two coaches, with total length of
18.5m.

9. IV . SKY STATIONS
 Sky Stations where sky buses halt
 Have automatic doors and Lift
 Smaller area consumption
 Fully computerized
 Entry only by electronic swiping cards
 Lifted 5.5 – 6m above Ground Level

10. V . TRAVERSE ARRANGEMENTS
 There are no points and crossings
 Automatically shifts the skybus units for balancing loads or change of
roots
 The traverser acts like a station.

11.  WORKING PRINCIPLE :
 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

12.  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

13.  WHY SKYBUS ????
 Conventional railway provides
for heavy steel coaches to
protect people .
 So carry more steel and dead
weight instead of people.
 With total weight of 48T, a
railway can carry only 70
persons in 20mLength
 But for metro it costs about 230
corers and for underground
metro it costs about 398-400
cores
 Sky Bus has no such problem,
no derailment nor capsizing;
hence uses very light weight
coaches and carries more
people.
 It uses much less dead weight
 Sky Bus with the same weight
& length carries 300 persons
comfortably
 The approximate construction
cost for skybus is about 45-50
corers/km

14.  SAILENT FEATURES :
i. Pollution free
ii. Noise free
iii. Economical
iv. Air Conditioned Travel
v. Can carry 36000 persons per hour (pph)
vi. Can be extended to 72000 pph
vii. Can shift 20ft containers for corner to corner.

15.  SAFETY MEASURES :
 Safety airbags are provided with each coach
 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%.
 Sky Bus- eliminating the problems of existing metro rail systems
like derailments, collisions, capsizing and crushing people.

16.  ADVANTAGES :
 Fast transportation
 Mass Transport
 No land acquisition problem
 No demolition
 No vandalism
 No capsizing
 Tourism
 Low capital and running cost
 Luxury
 No deaths due to trespassing
 Low maintainance cost
 No interference with normal
traffic
 Can be built on existing flyover
 No pollution
 Comfort to passengers
 No derailment problem
 Fire Protection

17.  DISADVANTAGES :
 Consume High Electricity
 High Initial Cost
But instead of thermal power plant use of hydraulic power plant can
produce more electricity .

18.  SKYBUS IN NEAR FUTURE :
 As it saves 50% - 70% of the cost it is seen as the future of metro.
 The authorities in Mumbai set up with the idea to consider setting up a
sky bus system on a 9.8 km sketch between Andheri and Ghatkopur .
 To the Tamil Nadu Government, has presented a possible route network
between Muthialpet in North Chennai to Athipet in the west — via
Koyambedu — and Mahabalipuram 45 km South
 The sky bus is proposed by Indian railways in India in following cities
Hyderabad , Pune , Mumbai, Bangalore ,Chennai , Delhi, etc.

19.  CONCLUSION :
 Research confirms that 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.
 Ultimately life is more precious than any other thing hence we need to
give safer transportation facility along with it economy also play
important role.
