It is a railway board policy and railway board is neglective towards Dhanbad for providing any new/extending train.Given Gaya have few dedicated trains and 22409 runs above 100% occupancy hence less chances of its extension unless any strong political influence which dhanbad didn't have.
please wait...Translate to EnglishDude, it's like this railway board rule, and the railway board is totally ignoring Dhanbad when it comes to adding new trains or extending them. Gaya already has a few trains exclusively for it, and the train 22409 always has more than full occupancy. So, the chances of extending it are low, unless there's some serious political pull, which Dhanbad ain't got.
please wait...Translate to HindiYeh railway board ki policy hai aur railway board Dhanbad ke liye kisi naye ya existing train ko extend karne mein laparwahi dikhata hai. Gaya ke kuch dedicated trains hain aur 22409 ki occupancy 100% se zyada hai, isliye iski extension ke kum chances hain bina kisi mazboot raajneeti prabhav ke, jo Dhanbad mein nahi hai.
