Jab he train Purnia se chalegi to departure kitna odd hoga...aur TAT bahut kam hoga...Why not ECR provide rake for Joshi exp ?? SER apna rake over utilize kyun karwa raha hai ?!? Better to convert this train with Sleeper AC gen..from purnia.. ECR should provide 2 rakes for it...
Ideal CC for Purnia Patna koshi exp should be 3ac-1;Sleeper-4;Gen-15;SLR-2
