Discard all ICF coaches or break the manufacturing chain of ICF coaches. Manufacture new LHB coaches and try some engineering to power all the coaches with single EOG/ make self generators. Effective use of HOG class LOCOS and renew the traditional layout of rails. Transform the rails into high speed (by less no. of joints). Speed will automatically increase by 50-70KMPH. Though will take some time, IR haven't introduced any new train in past two rail budget so apply all the profits into these with minimal labour coast and maximum technology cost.
