Kiraye se speed ka kya connection? high speed ke liye ab VB ya T-18 aayegi. Raj/Shat/Duronto/Tejas to pehle se hi high speed traine hain. kiraya to unka bhi badhega. ab push-pull se aur bhi speed badhega, lekin kiraya speed ke hisab se nahi badhta. ab ki baar kiraya railways ko honewale ghate ko rokne ke liya badhaya jayega, speed badhane ke liye nahi. jab track aur traine upgrade hogi tab speed badh sakta hai. lekin agar stops badhenge, to speed badhega nahi balki ghatega. is mein kirayeka huchh lena dena nahi. superfast surcharge ke sath bhi agar traine airlines ko chhod ke sabse fast aur sab se sasti hai, to kya dikkat hai? vaise bhi VB mein railfanning ke liye darwaaje khol ke doorplating nahi kar sakte. high speed ki ek kami. :)
