Hands down the best Route for a Lucknow Patna VB is via Kanpur Prayagraj DDU, as shown by this imaginary VB I made.
This is not the shortest route but this is the fastest one and is guaranteed to have more patronage than any other route.
I also made sure to make the TT as such it would not collide with any other...
more... train. A start at 0600 would have been ideal but then it would be sandwiched between Gomti and Tejas.
Give your thoughts.
