RAIL SAARTHI app is very useful for psgrs....just now I gone through this app 'one app more info's....IRCTC, ntes, complaints, uts booking...in uts there r two options 1.book and travel & 2.book and print
book and travel option is useful for those who travels in suburban trains
book and print option is useful for booking from any stn to any stn which the train goes in that route ...after booking we have to take printout in atvm machines
