KCG 715 extended portion it will arrive at 1145 and have to leave at 1700. The stabling lines should have watering facility. Being long distance train washrooms have to be cleaned which is done by use of hipressure water jet pump mounted on trolley which can be done only on PF. I don't know whether this jet pump is available at Kurnool though 3 trains are terminating and all are short distance. Taking to stabling line for 2.5hrs and bringing back at 1500 to PF for cleaning is a big task. May be SCr is waiting for new TT in which most trains will get speedup and change in timings to accomodate all extentions granted in Jan 2023. Even Uday can be extended to Guntur but there will be change in operational staff from Vja to GNT so not yet done. Same with Vskp KCG
