They already have Vasco Da Gama railway station they should develop it as a proper terminal by commissioning the 2nd pitline and terminating more trains there. Connectivity features are also pretty good there. As far as Verna is concerned it's an industrial estate and a small village that's why it is a freight terminal.
It's a shame that they don't even have a single premium train terminating at Vasco and all are usurped by Madgaon as if all rich people live there and Vasco is basically a slum.
