Sir, it moreover depends upon the convenient timings, favourable class of travel, availability of seats and penetration of services to that area. For eg. take the BCT ADI sector. If I want to reach ADI by morning, I would go for Gujrat Mail (the only non- AC train to have 11 AC coaches). But instead, I have work , which will get completed only by 11pm or so, then I would try Dadar Bhuj, even though I have to travel till Dadar.
