With work on the Kalwa-Airoli connector beginning, Railways has now put an end to the debate of how trains of the new corridor will continue onto the main line after Kalwa by designing a merger similar to that of Wadala where Bandra and Panvel locals alternate seamlessly without crossovers and detentions. 

This will not only ensure a link and smooth operation of local trains from Navi Mumbai-Airoli trans-harbour line to the main line towards Kalyan. Explaining the alignment, an official said that after the new Digha Gaon station, the line rises up to cross over the two mail/express lines near Parsik tunnel, cross over the slum colony where a new elevated Kalwa station has been proposed there. The line then moves ahead, bypasses the existing slow and fast lines and takes a turn towards the Kalwa car shed from where it runs parallel to the main lines for some distance and lands in the middle of existing up slow and down slow corridors.
