I was thinking why didnt ir didnt put another class in sf train.that is 3e coach. Lately I understood that they are not self generating.
In such why was design not made to make it slf generating. If this done, IR can introduce a class which carries more people n make more revenue.
Not going by which all trains need,almost every train has sl class n 3rd ac.
There...
more... is a segment wherd ppl can afford more sl class but fails short of 3rd ac.
