If a train is running full on the route it doesn't mean that other ones should be stopped to capitalise on the income from AC Superfasts.
Going by this logic, Railways should run only 1 Rajdhani to Mumbai and Kolkata and terminate the rest 2.
Not everyone can afford AC tickets, and neither does Shri Shakti cater to all the stations of NDLS-SVDK route. Railways is a public enterprise and before revenue, passenger facilitation should be there.
Even...
more... with Shri Shakti on the route, there's no doubt that USK will run full daily sparing some 1st AC seats.
It's high time that USK should resume it's operations.
