The stabling lines outside Tirupati Rly stn East towards Renigunta are already used to stable trains which have completed or taken to pitlines for SM/PM water filling. The lines doesn't have any water lines.As of now Tiruchanur station looks like a halt station rather then use as terminal as they are no water lines. If they are provided to PF 3 and PF 1 which are loop lines then some trains can start from there as terminal by waiting on the PF for 2 hrs turnaround time.
