good question. But in north any train A/c coaches will on demand. we cant compare those trains with this one. The trains which u mentioned started to DBRG after gauge conversion from GHY as trail. but it got very good patronage as they dont have much trains in that area. and it was used by army people more as well as tourists also now also the people above DBRG depends on this trains for faster connectivity, as further no train connectivity is there and Assam is mostly hill area and train is faster than bus. Now silchar connected so chances are there to extend one of these trains can go further also.
but here it is completely different. Comparing to...
more... that area here connectivity is good. and A/c express of A.P always have available seats in GNWL check and know this.
