In agartala s case I suppose there will not be much delays and trains can be easily flagged.Be among one of the new states to get the BG connection,there will be a huge fanfare and enthusiasm.I would like to see a Agartala-New Delhi Bi-weekly Rajdhani and Agartala-Sealdah Daily SF Exp to start upfront.NFR should give special attention to AGTL-SDAH as this alone will help connecting with whole Assam,Bengal and cities of Dharmanagar,Karimganj,Guwahati,Badarpur(link to silchar as well),Coochbehar,Siliguri,Malda,Bolpur and finally Kolkata gets linked.
