i just considered adding KMT as this is being such one big station which doesn't get priority for halting trains when compared to Warangal.
and As Gudur and nellore are in close proximity, i just gave preference to GDR being a junction.
Will try to add from the list provided and regarding the halts pattern
And i followed the present APSK pattern but reduced...
more... the no.of halts to bare minimum exclusding out twin states in that. :)
