Apparently, even the bad [as in very low mps tracks of PBH - SLN - AYC] tracks have been electrified and I saw this train running with GZB loco [as visible in image]. Sadly, I barely felt the acceleration commonly associated with such a loco and it moved at a snail's pace.
I only took a small trip in it b/w Basti to Babhnan and the AC coach was nearly empty. Probably few folks from Ayodhya might get in but I assume an AC chair car is more better for this train...
more... considering AC Three Tier is more expensive and this train is still a crawler.Maybe in the future, when mps of tracks are increased and stoppages at Gaur, Tinich are removed and train is extended to GKP, it can make sense; but currently, it's a dead horse to beat.
