@ Rasheed ali :
You mean to say no direct local suburban train from Panvel to Dadar. Yes, that' right. Just for information .... few long distance express trains are available from Panvel for going directly to Dadar, provided that train has general unreserved coaches.. Such trains are ... 0112/Konkan Kanya, 0104/Mandovi Express, 0166/Ratnagiri Passenger .... depending upon suitability of timings and trains running schedule.
@ One more way out is local trains from Panvel to Wadala to Mahim to Mumbai Central. This is bcoz at Wadala, you get many...
more... local trains. Few trains are there from Panvel to Mahim.
