One more possibility for SC TPTY VB is taking the route via Mahabubnagar, Gadwal Jn, Kurnool City, Gooty Jn and then Renigunta Jn... but the issue is that it's single line from Mahabubnagar till Dhone Jn... so don't know how will this work... cause that route distance is 644kms and can be covered in maybe 8hrs... so let's see if they would take this route.....
