People those who want to go Nagpur from Mumbai or from other station and not getting confirm ticket can book ticket up to Bhugaon which is next to Wardha (you have to get down at Wardha) and then book ticket from Wardha to Nagpur. You have to change seat as well as coach at Wardha Junction in same train (from slip train to main train). Because your ticket will be booked in slip coaches going to Ballharshah and the waiting list no. is less and easy to get confirm those tickets. And then board the main train (12139 CSMT NGP SEWAGRAM EXPRESS) to go Nagpur which is normally confirm.
