What I mean is, just building on existing railway lines may not serve current traffic flows since the cities have grown without these rail lines being a part of their commute. The only exceptions are Mumbai, Kolkata and Madras, since they have running local trains for over 70 years. See the lack of crowd on MMTS in Hyderabad, when compared to the former.
As for metro-like rolling stock, Mumbai has new shiny toys imported from Bombardier and Siemens for this very purpose. They don't like the dull drab ICF inspired caterpillar like rakes. Never mind that these phoren trains initially struggled mightily with the Super Dense Crush Load (yes, that's an official term) on Mumbai WR evening services, and our ICF rakes shrugged it off like Bhim and sprinted ahead
I believe most if not all the rakes currently in service in Mumbai are of ICF. Few BEML are alos used, but those are of faulty design.
For more on this, read this blog, it has good info and inputs.

This is probably why the Kolkata metro is a zone of the Indian Railways, and runs BG trains. And that is probably why other cities decided to go with SG . Heck, even Delhi changed its mind, given that they were in a Trishanku situation to begin with. The first two lines are built to BG standards, but the trains are mostly SG coaches mounted on BG bogies. So they paid the higher cost for BG infra, but have to squeeze in SG space. Generally, we should have gone with BG metro lines all over - our population will mandate it in the future and except these Trishanku tracks in Delhi, others will face severe congestion and can do nothing about it.
I completely agree.....with the amount of population and congestion, higher capacity is the need of the hour. And this is a prime reason monorail will not be a success here.
