Shirdi station does not have a daily slot available for parking rakes in the day time.

1) Bombay - Shirdi passenger between 10 and 5 (approximate timings).

On Tuesdays and Thursdays, MAS-SNSI and MYS-SNSI are also parked throughout the day, occupying 3 lines, leaving no line for reversing the loco of an incoming train.
On Tuesdays and Thursdays, the SNSI-Jalna DEMU arrives in the afternoon, and all 4 lines in the station are occupied in the afternoon.
The station can currently handle morning arrival/ evening departure for one more train on Mon,Wed,Fri, Sat and Sun. It is unlikely that they will use up that slot completely by increasing the frequency of the VSKP/TPTY trains.
