IRI - चाहे कितने भी हों मतभेद, फिर भी हम परिवार एक - Dr. Abhishek Rai

HS concept is good Vinay sir, problem is, just like everything else by central govt, in its implementation.
A superfast HS can generate profits like anything: entire rake is 3A, so everything inside can be standardized, the rake is air conditioned so less train resistance at high speeds and rakes are HOG which is very efficient and thus wastes less energy in loco.
A high speed superfast like mumbai Rajdhani has specific energy consumption around 15 units (energy required on average to pull 1000 tonnes for 1 km), the same value for EMU...

which has to constantly start stop is around 40!!
Add into it no concessions and dynamic fare abd you are literally looking at khuli tijori waiting to be emptied!
Problem is we have long distance HS wasting two entire days and running at a average speeds of less than 50kmph on routes where usually you have SF clocking in excess of 60 or even 70 kmph with sometimes non AC accommodation.
Patna banaswadi has decent schedule so gets patronage. Another good one is pune src humsafar.
