This morning my dad asked me a puzzling question which I'd throw open to all railfans to answer- What would be the longest (most expensive) journey by First AC from Mumbai to anywhere on Indian Railways network, strictly adhering to the following two conditions-
1) The train/trains used should be mail/express, passengers or superfast only. No Rajdhani/Duronto allowed.
2) Changing trains is allowed but the combination should necessarily follow the shortest direct route from Mumbai to the destination, so, for example, you can suggest going from Mumbai to Guwahati changing multiple trains to...
more... be in First AC all the way as long as the route being taken is same as the route of the shortest direct train from Mumbai to Guwahati. You cannot go Mumbai to Delhi and change train to go Delhi-Guwahati because there is a shorter Mumbai-Guwahati route available (though First AC is not available on that train)
Maximizing distance is not really important, what matters the most is that the First AC fare should be maximized!
I hope I have not confused you guys! Please suggest the "most expensive" First AC route
