Already MMTS is not Running with Improper timings.
You mean to say it is running properly or improperly?

Aren't these trains going to LPI? So,whats wrong making it official?

Do you know that MMTS gets priority against express trains and even Shatabdi as a train enters LPI? The schedule of many trains runs haywire in the morning due to MMTS. From LPI to SC, Rajkot SC express is held up at LPI for almost an hour most of the time.

Actually, long time time ago, Nizam had given his land for the construction of rail line from Hyb-Mumbai with the condition tat there should come up a station in that land and each & every train passing tat station should stop there. Tat station is nw Begumpet. I read this in Internet but forgot the site.
Tats the reason many of the trains hav stop there which has become a tradition.
But i hav seen many ppl catching trains from BMT

Yah especiall for HYB bound trains...
Have u observed diff,Most passengers of mumbai mail,hussain sarag,rayalaseema train passengers will use

That was James Street my dear friend. Begumpet was not a real station till the MMTS actually started years ago.

good idea just a group of ppl write a request and drop at railnilyam pro office,certainly it wl be taken care

Another reason to stop the trains at begumpet station is for the convenience for the passengers coming from hyderabad and old city. They dont have to go all the way to secunderabad and vice versa for passengers from secunderabad to board trains at begumpet and not go all the way to Nampally.

the reason for halt is convenience

For d same reason we have mumbai cstm bound trains halting at dadar, chennai bound trains at perambur, delhi bound trains a nzm/? and similar halt for hwh and sbc bound trains.
