I spotted this train with an A1 coach the other day at Aishbagh. Dunno why they felt the need to add it. I think AC Three Tier was enough, IMO. Still, since I could only catch a glimpse[ I was in another train from the adjacent platform], I am not sure if they removed one of the non AC coaches to add it or replaced B1 with A1. Hence, I am refraining from editing the rake of this train for now.
