8 coaches are very less. It should be a 16 coaches train. Demand is high for this route. And bypassing TPJ, would cut the travel time. If they want, They can introduce a separate VB till TJ or TVR via TPJ.
And MS-NCJ TT looks promising. Now we have 3 Premium Express trains till MDU from MS. Also, They need to focus on MS-MDU Tejas TT. VB is taking 5:38 hrs. And Tejas taking 6:15 hrs. Speed-up is required.
