I travelled in this train last october (15622) and as everyone says it is one of the underrated superstars. Was bang on time at almost all the stations. It has a good run from NJP to GHY considering that it runs through doors and GLPT. Only problem is that it has less halts at stations in UP, unclean stations with very less food options. Was halted at Sitapur city for 1 hour, reached SPC around 8.15 am and halted there for 1 hour. Then again halted for 1 hour after exiting GKP for reasons unknown. It can be easily speeded up by 1 hour. Once tracked this someday in January when even rajdhani was running several hours late; it departed ANVT 4 hrs late but arrived NJP +1:50 and KYQ +1:55. Most passengers in this train get down at KIR or NJP.
