Eh, that has been ongoing forever. Most projects are grossly delayed and over budget. Not a single metro outside of Delhi has any appreciably large metro rail system. Many have been in development for a decade. Projects get routinely stuck in political gridlock or because the builder went bankrupt.

The Bangalore metro project started in 2011. In over a decade, they've managed a paltry 56km of active rail lines - an average of 5km/year. Meanwhile, the city hasn't even had a master plan since 2016 and every government department works on its own without any collaboration whatsoever (resulting in disasters such as railway stations without any proper bus connectivity).

India's bureaucracy and polity will keep holding our infrastructure hostage.
