Yo, here's the deal with the train situation at this station. PF 1/1A is where the slow train to Kalyan rolls in. PF 2 is where the EMU train starts or ends its journey (recently, the slow trains to Kalyan have been using PF 2 if PF 2 is busy with other trains). PF 3 is where the slow trains to Thane are heading. PF 4 is where the fast trains to Kalyan are blasting through. PF 5 is where the fast trains to Thane are zooming by.

Is Station ke Trains ka Traffic Flow.
PF 1/1A (Ghar ki Platform/Double Discharge) → Kalyan ki taraf Slow Train.
PF 2 → EMU Origination/Termination Is Station se (Haal hi mein sab Slow Train Kalyan ki taraf PF 2 par hi aa rahi hai aur agar Origination/Termination PF 2 par rukne ka intezaar ho raha hai, toh PF 1/1A ka istemaal hota hai).
PF 3 → Thane ki taraf Slow Trains.
PF 4 → Kalyan ki taraf Fast Trains.
PF 5 → Thane ki taraf Fast Trains.
