Well SCR overall Always tries to Cover as Much Stations as Possible for any type of train, whether Permanent or Special.
Bext Examples are their Special trains and Most recently Launched ADI MAS Express, Most of the Stoppages it have in SCR region only.
Whereas CR is Concerned, from last 3-4 Years what I observed is that CR has started ignoring Most of its Major Stations also like Kalyan, Lonavala, Daund, Manmad, Jalgaon etc, nothing new with Gulbarga, Thane is also out of Question, even being the Busiest of all these stations,...
more... it generates the maximum revenue and passengers.
