Bhai that was only once it was done in full year...some AC coaches was replaced...also if i am not wrong the no. Of 2AC in the coach composition was reduced in 2018 because of less demand of 2AC in this special.....
Recently also once it was broken to take away 1 no. SL coach during 1st rake formation of Gitanjali exp...if you see the present rake of SHM-JP Spl..not AC Spl as u mentioned...1 no. SL coach is a new one with wide window in that rake.......
