Yes doubling was going in full swing between nagothane & roha. From Panvel to Nagothane doubling was commissioned & trains operational was started in 2016. Upto Nagothane to Roha doubling is almost completed only approx 1 km track doubling work is left. I think it will take 5 - 6 months more for completion. I seen the section on 4th Feb this month when I traveling in ne travail exp from thrissur to LTT.
