In the 24 hours of the day there may be 50 to 60 trains are ‘coming in’ and ‘going out’ of Bengaluru Railway Station. With every train bringing in 1000 passengers each, the number of passengers it is handling (1000 * 50) 50,000 people. And out of them (say) 5% will ‘go out / coming in’ in their own Vehicles, another 10% use Autos, the remaining passengers will come to Kempa Gowda Bus Station to go to their destinations through Buses.

Can we provide them easiest way to reach the Bus Station?


People cross the Railway Platforms through “Foot Over Bridge”. The Foot over Bridge height say 30 ft height. If we use a Lift for another 30 ft height, totaling the height is 60 ft height. From that height at the Centre of the Railway Platforms to Bus station we provide, a Path Way. It is just like a RAMP. People come down easily to Bus Station without any hurdles, like crossing Platforms, parking area, subway, steps, etc.

We can provide trolleys with 20 passengers (2 Tons weight approximately) each which can slide easily to the distance and save the time & energy of the Passengers.

Advantages in this Project:-
(1) There is no Private Property in between these two points – Rly Stn & Bus Stn.
(2) The height of the Foot Over Bridge at Railway Station and the Ground Level at Bus Station may be more than 60 ft
(3) In addition movement of men / material, there will be scope of Power Generation – By sliding the 2 Tons Load Trolleys on the Rails on RAMP along with Pathway.
A layman’s – ‘Power Generation Calculations’. - .5 M.W.
As per notes from attachment, (Work & Energy Chapter – PAGE 6) the following is the ‘Power Generation Calculation’.
Please follow Link:-

This calculations I made for Benagaluru Path Way Project. Is it correct.
2Tons Load (20 – Passenger filled car) generates 278 watt per hour as per enclosed attachments.
2000 x 10 x 50 = 10,00,000 Joules = 278W 278 W
When train arrives into Railway Station, let us say, 1000 Passengers reach, get down and use the Transport will be 800 nos. 800 Passengers will be transferred in 40 Loads (800/20 = 40). 40 Loads
For every ‘four’ loads the Power generated will be more than 1 Kilo Watt (4278 = 1,112). 1 K W
With the Passengers in one train (40 Loads) we can generate 10 Kilo Watt Power per hour. 10 KW
With the Passengers from 50 trains per day, we can generate 50
10 = 500 (.5 MW) Power. 500 KW = .5 MW

Dear Mr. RL Swamy,

as per our discussion, I minute our meeting as below.
Points to Consider

  1.   Span of the Pathway: Approximately 200 – 250 meters in Bangalore
  2.   Width of Pathway planned: 30 – 40 feet
  3.   Self weight of the structure + weight of people + luggage
  4.   Intermediate support requirements
  5.   End stage extraction facilities

Scope of work.

  1.   Industrial Design
  2.   Engineering Design.
  3.   Design Validation with load calculations 
  4.   Prototype preparations to suitable scale

We would be interested in taking up this project further.
Let us have some agreements in place before we actually commence work on the project.
Best regards

Dear Sir,
As discussed ue have worked out a proposal of Roller Coaster for TIRUMALA Hills as follows.
The Roller Coaster will be designed in two parts part 1 is with the lift of 83M & 30o and part 2 from 83 to 165M.
Now we can consider to designs for the Roller Coaster.
Design 1

  1.  Roller Coaster with Chain & Sprocket Drive: -  The Roller Coaster will consist of four trains each with capacity of 16 persons. The train containing passengers is pulled up by the driving chain which is driven by the electric Motors will be released at the height of 83M. & 165M. respectively. 

The train after deboarding the passengers at 165M. will decent down on a slope under the influence of gravity. The speed of the train while coming down is controlled by slow down brakes fitted in the track.
2. Roller Coaster with DC Drive: - In this design A no of cars with capacity of two or four persons are fitted with the DC Motor which drives the Roller Coaster by Pneumatic /Rubber Tyre the current needed for the drive is supplied by the current collecting system fitted in the track. Suitable sensing system is fitted in the track to avoid the collision of cars.
In our opinion the design with DC Drive can be preferred over the chain & sprocket design this can be discussed during the finalization of design specifications.

In our opinion the cost of designing such a Roller Coaster would be around 8 to 10 Lacs.

We hope this to be in line with your immediate requirements in case of any clarification please feel free to contact us.
