I advise you please do a basic research going to debate on any topic

Manmad dhone via sc,kurnool and akola-indore was one of the most north south , west south connection of pre independence india
It suffered a lot due to selfish motives of politicians from Karnataka, Maharashtra and coastal ap..first they kept this line in cold storage with the name of project...

broad guage .. one will hardly believe that the line part in Telangana was closed upto 2004 , this line was reopened in mid 2004

Coming to your question will wadi route serve the purpose
1)first the route needs to cross the secunderabad station .. already current trains at sc stop 20 min at outers...
2) sc lpi zone is occupied by mmts emu trains which are lifeline for the software companies , also mmts project doubling was done with state government cooperation
3)sc lpi zone has many coastal Andhra residents that is the reason all ap bound trains originate from lpi
4)sc lpi line is used to connect towns like mumbai, solapur,pune, bijapur,hubli,goa bound trains,latur, gulbarga, Bidar, there is high scope for intercity in bw these towns
5) sc Wadi line is dominated by cement frieght
6) so the sc kcg dhone line will serve as short cut and traffic free line for Hyderabad banglore and Hyderabad Chennai trains and majority of chennai/banglore -delhi/jaipur trains can be shifted through this
7) Hyderabad international airport falls on kcg dhone route
8)either you have to quadraple the sc lpi line which falls in core commercial area of Hyderabad which will cost a huge or u can double the kcg-dhone line which falls in remote and under developed areas

i understand your frustrations.
but fyi just look at the pic. There are 5 tracks but there are also 5 freights simultaneously on them.
Railways is politicsed, fully agree.

is known as the Coal India Corridor. Most of the coal production and loading is done along this line and this line feeds the grand chord at DHN,GMO,SEB and CAR respectively. This line is yet to be fully doubled.
as for whether DHNE-KRNT-KCG-SC deserves doubling . i never said no na bro?
my only point was that it was unfair to compare the grand chord with the DHNE-KRNT-SC line. that is all i said.

Comparisons is being drawn after "5th" electric railway line was being laid sir. We never said anything when the line was doubled, tripled, quadrapled. Are we people and the resources here are looking so much so useless that a single diesel line is being made for adjustment and another region is getting 5 electric railway lines?
If you are talking about alternatives I have attached a picture.You can see almost all Double electric railway line there. So there wasn't a need of DFC if already "alternative" was there. Even now we aren't asking for 5 lines sir. We are just asking a DOUBLE ELECTRIC RAILWAY LINE for a distance of 183 km so that Banglore gets closer to Delhi, UP, MP,...
