Nahi I mean to say ki suppose train A already Lhbfied hai jisme suppose 10SL coaches hai train B ko Lhb hona hai jiske liye manlo 8 3E coaches allot hua hai according to the list aur 2 SL. Toh jab rakes ayenge toh iye 3E coaches mutually distribute ho jayenge matlab Train A ke 4 SL coaches hatake 3E lag jayenge aur uske Sl train B ko de diye jayega. Toh isse train B ko pehle ke alloted 2 aur train A se mila hua 4SL milake 6 SL coaches aur 4 3E coaches ho jayega. Aur train A bhi 6 SL aur 4 3E coaches se chalegi.
