Eog stand for end on generation.Iska kaam hota hai AC Coaches ko power dena.Eog ke andar ek diesel generator laga hota hai jisse AC Coaches ko power milti hai.
Hog stands for Head on generation.Ye new feature hai hai aur uski wajah se ab Eog ki jaroorat nahi parti.Hog Locomotive me rehta hai,Ohe se jo power locomotive ko milti hai wahi power cables ke through Coaches me jaati hai jisse Eog ka jaroorat nahi paregi.Simply Hog se OHE se power Pantograph ke through loco me jaati hai aur wahi power cabled ke through Coaches me jaati hai jisse AC aur lights work karta hai.
