One of my friends booked a telescopic ticket from Solapur to Dibrugarh by Hutatma/Azad Hind/Kamrup train, in sleeper class. He was issues 3 tickets corresponding to 3 legs of journey. The total fare was Rs.880/-. Due to some reasons, he had to cancel it. Cancel charges was only Rs.60/- with a refund of Rs.820/-. Total km is 3665. Travelling cost works out to approx. 24 paise/km. IR is really very very economical. Hats off.
