This document presents information on Sky Bus technology. Sky Bus is an elevated rail system that runs on tracks supported by columns above existing roadways. It was first developed in 1989 and launched in 2003 in India. The system uses lightweight coaches running on standard railway bogies along concrete tracks placed in an enclosed box structure up to 10 meters above roads. Stations are automated with computerized entry and service every 2 minutes. Advantages include mass transit capacity, no land usage, and reduced pollution. Disadvantages are high initial costs and electricity usage with high maintenance. The system aims to provide inexpensive public transportation without disrupting traffic below.

2. Introduction
 It is latest construction technology
which save time and money resulting
in easy execution of the project in
busy urban areas without disturbing
the existing traffic pattern.
 Sky bus technology launched 15th at
2003 at madgaon ,goa .

4. Discovery
 it is developed by
Mr. B. Rajaram.
 Sky bus metro
concept first
presented in
bologna university
italy ,by him in
1989.
 It offered by
konkan railway.

5. Description
 Heavy 52l60 kglm rails placed at
standard gauge floating in elastic
medium and damped by interia of
measured mass held in a 8m*2m box
enclosure, supported over a 1m
dia.column spaced at 15m and
located at 15m distance from each
other.

6. Capacity
 Can carry 18000pphpd-72000pphpd.
Can shift 20ft containers for corner to
corner.

7. Working principle
 Standard railway coach running on
railway track.
 The under frame with standard
railway wheel set running on railway
track.
 The railway wheels remains same
,they on same track ,the coach is
firmly attached.

9. In a curved manner

10. Compnents
sky way
Sky bogies
Sky coaches
Sky station
Traverser arrangements

11. Sky way
 It consists of
concrete box
structure carried
over a series of
piers at a height of
8-10m above
existing road level.
 Two rails fixed with
fastening within
the concrete box
support and guide
the sky bogie .

12. Sky bogies
 Standard two axle bogies.
 Speed of 100 kmph (max 160kmph).
 Linear induction motor-to be driven.
 Disc &emergency brakes.

14. Sky coaches
 double walled
light shells –wide
large windows.
 Air –conditioned
travel –automatic
doors.
 Audio visual
information to
passengers.

15. Sky station
 Smaller area
consumption.
 Fully computerized
–entry by electronic
swiping cards.
 Totally automated
without drivers or
guards.
 Service is every 2
minutes –no waiting
time for passengers.

16. Entry & exist portion

17. Traverser arrangements
 Traverser is a
system which
automatically
shift sky bus
unit from one
track to
another .

18. Advantages
 fast transportation
 Mass transport (36000pph& max up to
72000pph as required)
 No land problem
 Fire protection
 Noise free
 High capicity
 No pollution

19. Disadvantages
 Consume high electricity.
 High initial installation cost.
 High maintenance cost.

20. Why sky bus saves 50% to 75%
 Convential 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 20 m
length.
 Sky bus has no such
problem .no
derailment hence uses
very light weight
coaches and carries
more people using less
dead weight .
 Sky bus with the same
weight &length carries
300 persons
comfortably.

21. Future scope
 For overpopulated cities ,it is safer.
 Inexpensive mass public
transportation .
 Sky bus is an improved railway
technology ,eliminates the problem
of city suffering from heavy traffic.
