The current composition is 2 AC Chair Car, 11 2S and 2 DR. Total 15.
All 15 were passenger carrying coaches.
If 22 coaches JS is made to operate it will be 20 Passenger carrying coaches. I don't think there will be a increment of 5 coaches.
Same happened for bza -mas js to lhb but they keep cc to 16 I think
Future js tag can be off or if patronage for 22 not there cc may reduce
Ecor could have easily started new train small cc 8 coacher to new place for that eog'needed ,js lhb to 14-16 coacher
JS is getting good demand but not that good demand to get 22 coaches. Present number of coaches is enough as of now. Remaining coaches should be transferred for dhauli
No need for new train present trains like dhauli or blgr Intercity can be provided with lhb coaches
