There is no scope of doing that.
To reduce the burden on Kacheguda, railway can shift the existing pitlines to Falaknuma, that will add 2-3 platforms. They have to also lay a 3rd line between Falaknuma & Kacheguda to continue the movement of trains.
Secunderabad,...
more... I am not sure how it can be expanded even more. Unless the entire parking & concourse is moved underground new platforms can't be added.
Though to reduce the platform occupancy there is one possibility to extend some of the existing terminating trains to either Malkajgiri or Medchal (though both stations will need some enhancements before doing so).
