Now NTES is showing 20:03/05 and IRCTC 19:48/50 at Warangal for 02622
yes and train is coming daily as per ntes timings only
NTES is mirror of train's run, synced with Controller & Board while booking sites usually are updated after a long gap!!
There has been example of a train whose NTES Dep was earlier to irctc & Train departed only at the time mentioned in irctc (30 Mins halt)!!
Anyhow to show train's dep at 19:50 while it may dep at 20:05 will not make anyone miss the train but to show 20:05 & if train departs at 19:50 will make many miss it!!
