The Best to do is, retain TVC Rajdhani as triweekly, and introduce a new triweekly rajdhani via Panvel-Itarsi and a weekly rajdhani via NCJ-MDU-BZA.
The ERS-NZM duronto can thus be extended to TVC and rerouted via BZA as a weekly AC superfast express with minimal stops at QLN,ALLP,ERS,TCR, PGT,CBE,ED,BZA,Bhopal
