#bookingtip
If wish to travel from mumbai to delhi, then you have book well 1 month in advance specially in sleeper. Its always full for mumbai to delhi quota as along with NZM, meerut and SRE also come in same quota.
Take RLWL less than 40. Above it in sleeper , its very tough to confirm.
If you dont get tickets,then there is...
more... three ways by which still you can travel from mumbai to delhi in this train:
1. Check BCT to JRC as its in GNWL ASR end to end quota, which majority of times remains vacant. If getting GNWL in SL till 60-70, take it. Confirmation has bright chances.
2. Check ST/BRC to NZM, sometimes this quota also remains vacant (personal experience) in SL, take it if don't wish to waste money. Reach ST by any earlier train and catch this.
3. Last option keep for premium tatkal. This is sure that you will get confirmed seat.
But during diwali and holi rush, don't wait and book 120 days arp. This train is a high demand train throughout 365 days but during diwali & holi, it gets filled up on the 1st day itself.
