Do you know railway runs sleeper class on heavily subsidized fare from which they don't even earn enough profit. Railway only recovers 57% of operating costs. You want sleeper class people to pay same fare in bullet train as they pay in sleeper class, right? Time is inversely proportional to money. You will save a lot of time when you will travel by bullet train and inside you will appreciate it too. Your double standards clearly reflects when you don't even have any problems with rajdhani, Shatabdi, and Duronto but have problems with VB. We live in capitalist country where more you pay more services you get. You can't expect cheap prices for high speed travel which will be enabled in bullet train. Sleeper class can't run above 130 then when Delhi Mumbai and Delhi Howrah will be 160 capable then obviously only fully AC class trains will be allowed to...
more... go 160. Then don't cry later that my sleeper train is only running at 130.
