For the majority of the general population in India, Railways serve as the prime mode of travelling owing to its reliability and low cost fares. More than 23 million individuals utilize trains to travel from one to another on a regular basis. In any case, not many people know the actual significance of the 5-6 digit number which is written on the outside of the train compartments/coach.
Each train in India has this kind of numbers recorded on its coaches. These are for the most part 4,5 or 6 digit numbers out of which the initial 2 digits means the time of production. For instance if the number is 8439, it implies the train was made in 1984 also if its 04052, then it was produced in 2004. But still there are few trains which don’t follow this normal practice of classification particularly the Rajdhani express with the number 2951/2.
The rest of the numbers in the digit connote the kind of train whether its AC special or sleeper. Lets take a close look at how that actually functions :
001-025: AC First Class
025-050: Composite 1st AC +AC-2T
050-100: AC 2T
101-150: AC 3T
151-200: AC Chair Car
201-400: Sleeper 2nd Class
401-600: General Second Class
601-700: 2L Sitting Jan Shatabdi Chair Car
701-800: Sitting Cum Luggage Rake
Also The WCR, EF and NF means that the train is manufactured by Central Railway, East Railways and North Railways respectively.
