Ya Agreed With U that No Single Train Runs From Mumbai CST/LTT To Vasai Road.. Ya Main Line Has To Be Halted Just Once.. But It Would not Affect Much As It Will Take 5th Line From Diva via Cross Over Before Diva Station Done By Many South Bound Trains From Mumbai.. And After That A Huge Curve For Vasai Line.. But Isse Bhi Jyda Complicated Hai Going From Vasai To Panvel.. Which Is Done By Many South And North Bound Trains With Heavy Cross Overs.. And As A Commuter Travelling From Last 5 Yrs From Asangaon - Kalyan To Dadar / Vadala Road.. I have analysed each and Every Track of this belt.. It is not so tuff to run Trains from Mumbai CST/LTT To ADI.. Also WR Has Started Running Trains From Mumbai Central / BDTS To Mangalore/ Madgaon Which Is Much More Tedious.. Having LR At Vasai...

And Then Going Towards Panvel With Heavy Cross Overs.. So If WR Can Take Such Initiatives Then CR Would Also Do.. In My Point Of View It Is Not That Tuff To Run A Train From LTT/CST To ADI / JP.. Jo Cross Over Most Of The South Bound Trains Karti Hai Utna Hi Karna Hai.. And Remember It Is More Tedious To Go From Vasai To Panvel Instead Going From Thane - Diva To Vasai.. Hope U would Understand..!!

I disagree here.
BSR to PNVL , the train uses the normal tracks till CR main line , and then runs on the farthest most branch line towards Left side (While going from BSR to PNVL) ad then again there is no crossover at all near Diva Jn as the train directly goes to the Left hand tur towards the PNVL main line.
But if a train is coming from BSR side, then after Kopar bridge it has to get on the CSTM Main line , otherwise it can never go towards CSTM....

And this coming up on Main line is a very tedious work as for a single train to enter the main line , atleast 15 minutes clearance window is required from Kalyan side which is very very tough. Already Kalyan-Thane main line is fully congested due to LTT , CSTM , Dadar bound trains coming from Kasara and Pune side , Plus the additional Pune trains going towards western route. Its very schedule wastage for running a Western route-CSTM/LTT train.
The konkan bound trains crossover the main line near Diva Jn where its a regular and normal scene but a CSTM-ADI train would be needed to cross over the tracks from Domvibali area (before Kopar station) which is Not suitable to do this as it would first directly cross over from Up line to Down line and then to Kopar branch line , That means Stopping the traffic on Both ways (UP & Down) just for allowing a train to cross over. Bro kalyan and Diva ka haal fir samajh rahe ho kya ho jayega ?
Ek ke baad ek train queue ho jayengi...Bcoz at least 15 minutes is needed to allow the train fully cross over the main lines.
Thanks.
