there is no timing issue..11025 arrives at KYN on pf 5 and deccan arrives on Pf 6..while deccan don't overtake 11025..beacuse 11025 direction is Mumbai then it goes till diva cabin and changes direction to Panvel.after departure from panvel..it changes to karjat line..this is how it goes to pune..coming in Mumbai direction and changing direction from diva cabin towards Panvel then karjat
