Mumbra Kalwa 5/6th line karke CR / IR/ Government ne janta ka paisa waste kiya hai. Express trains and Mumbai local still share tracks. They could plan well and ensure only track sharing takes place from CSMT to Vidyavihar. From Vidyavihar to Kalyan, they have 6 lines now but not utilizing it properly. If you check in morning, Mandovi express from CSMT to Goa runs from Kalva. So at crossing at Diva, they have to stop EMU towards Thane. Further, if they wanted to run fast trains via Kalva, why did they waste money and built platforms at Kalva station? I was hoping that CSMT semi fast which go slow after Thane wont change tracks and these new platforms will be used but that too is not the case.
