That is brilliant information mate. For some reasons i have always fancied overhead electrification of the electric locos. Thanks for sharing that.View attachment 321642

There are four tubes which makes the complete cantilever assembly namely
Stay Arm: It comprises of dia 28.4/33/7 mm (Small) size tube and an adjuster at the end to keep the bracket tube in position. It is insulated from the mast by stay arm insulator.
Bracket Tube: It comprises of dia 40/49 mm (Small) or dia. 30/38 mm (standard) bracket tube and insulated by bracket insulator. Catenary is supported from this member by catenary suspension brackets and catenary suspension clamp
Register Arm: It comprises of dia 28.4×33.7 mm tube to register the contract wire in the desired position with the help of steady arm
Steady Arm: It is 32 x 31 mm BFB section made of aluminum alloy to register the contact wire to the required stagger and to take the push up of contact wire. It is always in tension
Dropper is a fitting used in overhead equipment construction for supporting the contact wire from catenary. Two top tubes hold the weight; adjust the height and center of the Contact and catenary wire assembly whereas the bottom two tubes for adjusting the contact wire – stagger/height.
Contact and catenary assembly is designed for following different applications namely, push, pull, overlapping, crossover etc. The arrangement of the cantilever depends upon the height of the contact wire, encumbrance, setting distance, stagger and super elevation.
Stay and Bracket tube is supported on the mast with the help of insulator for electrical isolation called Stay Tube Insulator and Bracket Insulator. Two standard sizes of tubes 38mm and 49mm outside diameter are used for bracket assembly depending on the loading condition. Bracket assembly permits adjustment of equipment to cater for slewing or raising of track during maintenance. Length of stay tube can be varied by as much as 9 cm. in either directions and bracket tube is provided with free length of 10 cm beyond the caternary suspension clamp. Similarly projection of the register arm beyond the steady tube clamp is kept at 15 cm. This makes it possible to adjust the stagger of OHE at later stage without much difficulty.
Most important feature of Cantilever assembly is its flexibility, swiveling in all direction to take care of vertical push during movement of pantograph and expansion during change of ambient temperature and Vertical and Horizontal adjustment.

You do know that he has been in power for only two years. One can only do so much in two years.Big ticket items, PM is involved.
he should handle everything in a prudent manner.
His mishandling of such issues involving International trade would have ripple effects.
And BTW, check #212
In that article you will find, among all: mention of PM Modi & Khadi.
Now tell me you.
What is the relevance of Khadi with Indian Railways?
And I see that on post number #212, you have no objection, because you never came against that article.
Trying to be flippant? because Modi is your God?
Just one word of "Modi" and you are in jitters?
Why be selective?
Somebody posted this:
In this thread, did you ask him what is the relevance of this with Indian Railways?
Why your feathers get ruffled on one "Modi" word?
This thread is purely about Indian Railway's development past, present and the future. Let us stick to that.

I am no Modi fan either infact i have bashed the central govt countless times over the center vs Delhi turmoil. But I do believe that Modi is honest with his vision for India's future just as Kejriwal is a honest guy despite of what people says about him here.
So let us stick to the topic here and keep the political bashing limited to the Indian political threads.
I have a question, hope to get India friend answer, India's general how much is the train fare?
Sir, depends on what class you are traveling on and offcourse the distance.India's general how much is the train fare
Again you don't need to clarify that Modi is = PM. Everyone knows that.You tried to make a mountain out of a mole hill.
And you failed.
Modi = PM.
If there arises any anomaly in International trade dispute, handling, or otherwise, India's policies will be attacked, and who takes the hit being the top boss?
Modi again. And he will be mentioned.
2170 kilometers of travel just $6.8??? 42 yuan, this incredible, not including any service? Don't even provide food and water?Means the lowest class of accommodations ?
For a 2,170+ kilometre travel in lowest class you will need ~460 INR. Roughly 6.8 Dollars , but you don't get a reserved seat , no sleeping bunks,you get fans , lights , a charging point , and a latest addition of a RO filter in the coach itself.
Quite cheap if you are 3-4 friends and each manage a seat!
Figures are fo Tamil Nadu Sampark Kranti , running from Chennai to New Delhi.
Yes no food . But new coaches will have RO purifiers , so water will be free . You can get food on the station's , 70-80 INR will be enough for a tasty and satisfying meal , will not be too great , but good enough.2170 kilometers of travel just $6.8??? 42 yuan, this incredible, not including any service?

Ok, So how much is the most expensive?
Day, I see the huge price difference between the two country...Yes no food . But new coaches will have RO purifiers , so water will be free . You can get food on the station's , 70-80 INR will be enough for a tasty and satisfying meal , will not be too great , but good enough.
The most costly ,its 1St AC , costing INR 6,335 or near 95 USD, for the same 2170+ kilometres , Bedding , Food( meals , refreshments included) , Water , Towels , and a 4 or 2 cushioned bunks with doors , and of course WIFI, free....
Not that costly....
Price difference , well there are 2 reasons I seeDay, I see the huge price difference between the two country...
Perhaps India is really full of business opportunities "golden state"
The deepwater D/S Chikyu as deployed during NGHP-02 was designed by the Japanese government for international scientific drilling operations.A joint expedition by India and the U.S. discovered a major deposit of natural gas in the Indian Ocean, offering the potential to significantly expand energy production in a region that’s currently a big importer.
- Find may significantly expand regional energy production
- Gas locked in hydrate formations may exceed all known supplies
India’s Ministry of Petroleum and Natural Gas and the U.S. Geological Survey struck a large, highly enriched deposit of natural gas hydrate -- an icy form of the fuel -- in the Bay of Bengal off the country’s east coast, potentially the first producible reserve of its kind in the waters, the U.S. agency said in a statement Monday.
The finding may add to the world’s expanding supply of gas. The amount of the fuel contained in the planet’s gas hydrate accumulations is estimated to “greatly exceed the volume of all known conventional gas resources,” the agency said. The discovery also comes as countries like India and China seek to slash their dependence on higher polluting energy sources like coal, which releases twice the heat-trapping emissions as natural gas when burned.
“Advances like the Bay of Bengal discovery will help unlock the global energy resource potential of gas hydrates as well help define the technology needed to safely produce them,” Walter Guidroz, energy resources program coordinator for the U.S. Geological Survey, said in the statement.
The discovery follows an exploration of the region from March to July of last year. While earlier finds of hydrate accumulations were unlikely to be producible, formations in sand reservoirs like the one announced Monday are the most easily tapped with existing technologies. The next step is to determine whether production from the Bay of Bengal site is economic.
“The results from this expedition mark a critical step forward to understanding the energy resource potential of gas hydrates,” Tim Collett, a senior scientist with the U.S. agency, said in the statement

Where does it say the discovery is in Indian ocean? It's in the Bay-Of-Bengal and now any thoughtful person can figure out on why massacre and destruction of the patriotic forces in Bangladesh basing on lie, damn lie,recurrent lie and deception.
