fare hke is very common now. now we may c hike in fare every now and then in the name of fue adjustmnt components due to hike in price of desiel. i have one question. why do we not cosider run ning traind loco only. or our researchers must step ahead to run trains by clean enery viz nuclear, solar etc. this will not ony reduce cost price for railway but also be eco friendly due to no smok emulsion. it will bea boon in long term.
