What are the advantages of the First AC coach in Indian railways?

 

  1. The main differences between First AC and other AC Classes on the Indian Railways are privacy and space. There are a total of 18 passengers in a First AC Coach. To revisit the question of space, compare the number of passengers in a First AC coach to the total number of passengers in a coach in the other classes of accommodation:

    AC First:
    18-24
    AC Two Tier:
    46-54
    AC Three Tier:
    64-72
    Non-AC First Class (Very rare): 26
    Sleeper Class (Non AC):
    72-78
    Unreserved Second Class: Officially
    90, in actuality as many people as can be crammed into the coach!
  2. you can carry a dog in First AC/First Class. Dogs cannot be carried along with you in the coach in any other class. However, the carrying of the dog in First AC is subject to the following conditions:
    i. You must have reserved an
    entire two-berth coupe or four-berth cabin [If you don't have the entire coupe/cabin and other passengers object to the dog, the dog will have to travel in the 'dog box' in the guard's van, which will probably be the most traumatic experience ever for your dog.
    ii. You must purchase a luggage ticket for the dog at the luggage booking office.
  3. The ability to keep the door of your cabin/coupe bolted from the inside. No other class (except First Class Non-AC) offers this; even in AC Two Tier and AC Three Tier, the only 'protection' offered is a curtains.
  4. Thus, for people carrying expensive luggage (For example, if you're a photographer and are carrying all your camera equipment), the door could provide peace of mind.
  5. Primarily in the Rajdhani Expresses, especially the Delhi-Mumbai and Delhi-Calcutta Rajdhanis. Here, food is prepared personally in the Pantry Car and passengers have much more choice (Unlike the other classes where food is prepared and packaged at intermediate stations and loaded onto the train). However, this is applicable more only to premium trains. Even in normal trains, however, First AC passengers tend to get better service.
  6. Interaction in First AC is extremely low. Generally, the higher the class, the less the interaction. This can be a plus or a minus depending on your orientation and the purpose of your travel.

Why is the first AC coach train fare so high?

 Want to take a bath? Yes in the train? You have a shower option in the first Ac coach. That's different will it be clean or not?

Are you a couple? Need privacy? Indian Railway trains give you the option for a coupe and an exclusive private room on the train.

You don’t have to say excuse me sir during the lobby in the First AC train? None legs and hands are spread in the lobby.

You don’t have to beg for lower birth because you are aged or scared to climb on difficult steps of trains because First AC will give you a comfortable ladder.

Wanna taste good foods? Or fresh food direct from the Kitchen? The first AC provide the option of fresh food cooked at the train's pantry and delivered to you before it gets cold.

So tell this much facility that too on train will not be costly? Yea same train where in 3rd AC or sleeper people are fighting that in morning their is no reservations and non reservation people can sit on your seat.

ಜಗತ್ತಿಗೆ ಮೊಟ್ಟ ಮೊದಲ ಬಾರಿಗೆ ಎ ಸಿ ಕರೆಂಟ್ ಅನ್ನು ಪರಿಚಯಿಸಿದವರು ಯಾರು?

 ಜಗತ್ತಿಗೆ ಮೊಟ್ಟ ಮೊದಲ ಬಾರಿಗೆ ಆಲ್ಟರ್ನೇಟಿಂಗ್ ಕರೆಂಟ್ (AC - Alternating Current) ಅನ್ನು ಪರಿಣಾಮಕಾರಿಯಾಗಿ ಪರಿಚಯಿಸಿದವನು ಮತ್ತು ಪ್ರಚಾರಕ್ಕೆ ತಂದವನು ನಿಕೋಲಾ ಟೆಸ್ಲಾ (Nikola Tesla)

ಇವರು

  • Tesla Coil – ( used in radio, wireless power transmission ) ಅನ್ನು ಕಂಡು ಹಿಡಿದರು.
  • Polyphase system – ಅನ್ನು ಅಭಿವೃದ್ಧಿ ಪಡಿಸಿದರು.
  • AC motor ಮತ್ತು transformer ಗಳನ್ನು ಅಭಿವೃದ್ಧಿಪಡಿಸಿದರು.
  • AC ನ ವಾಣಿಜ್ಯ ಬಳಕೆ ಸಾಧ್ಯವಿದೆ ಎಂಬುದನ್ನು ತೋರಿಸಿದರು.
  • 1880ರ ದಶಕದಲ್ಲಿ George Westinghouse ಅವರ ಸಹಾಯದಿಂದ ಟೆಸ್ಲಾ ತನ್ನ AC ತಂತ್ರಜ್ಞಾನವನ್ನು ಉದ್ಯಮದಲ್ಲಿ ಬಳಕೆಗೆ ತಂದರು.

DC vs AC: "Current War" ಬಗ್ಗೆ ನಿಮಗೆ ಗೊತ್ತಾ?

ಇದೊಂದು ಐಡಿಯೋಲಾಜಿಕಲ್ ಮತ್ತು ಪ್ರಾಯೋಗಿಕ ವಿದ್ಯುತ್ ಯುದ್ಧ.

  • Thomas Edison(ಬಲ್ಬ್ ಕಂಡು ಹಿಡಿದವರು)– DC (Direct Current) ಗೆ ಬೆಂಬಲ.
  • Tesla & Westinghouse – AC ಗೆ ಬೆಂಬಲ.

Edison ವರು DC ಅನ್ನು ಹೆಚ್ಚು ಸುರಕ್ಷಿತವೆಂದು ಹೇಳಿದರೂ, Tesla ಮತ್ತು Westinghouse AC ನ ವೈಜ್ಞಾನಿಕ ಸಾಮರ್ಥ್ಯ ಮತ್ತು ವ್ಯಾಪ್ತಿಯನ್ನು ತೋರಿಸುವ ಮೂಲಕ AC ಯನ್ನು ವ್ಯಾವಹಾರಿಕವಾಗಿ ಮಾಡಿದರು.
