Not at all a reliable train. Though speed is good after MGS but punctuality is almost Zero. Travelled from BSB to HWH & had such a horrible experience. Train departed BSB at midnight ( 6 hrs behind its schedule ) & reached HWH next day at 16:10 hrs ( 8 + hrs late ). We had to book in sleeper coach as AC coaches were already waitisted & had to spend the next day suffering & suffocating under scorching temperature . Also many UR people boarded the train after Patna & occupied the seats. .Worst journey ever in an SF train. Even if it departs on time from ALY/BSB then also it reaches late .
