You are wrong, Indian railways does not operate metros.
en.wikipedia.org
Hyderabad Metro Rail Limited (HMRL)
Similarly, Bangalore, Kolkota and several other cities have their own metro corporations operating outside the Indian railways. Their annual traffic is 4.7Billion. Indian railways as an organization transports 8 billion people.
If you combine both it is 12.7 Billion
I'm not talking about "metro."
(China has 32 billion metro riders a year.)

Suburban rail plays a major role in the
public transport system of many major Indian cities. T
hese services are operated by Indian Railways. Suburban rail is a rail service between a central business district and the suburbs, a
conurbation or other locations that draw large numbers of people daily. The trains are called suburban trains. These trains are also referred to as "local trains" or "locals". The suburban rail systems in Hyderabad, Pune, Lucknow–Kanpur and Bengaluru do not have dedicated suburban tracks but share tracks with long-distance trains. The suburban rail system of
Mumbai,
Kolkata and
Chennai have both dedicated tracks and tracks shared with long-distance trains.
The first suburban rail system in India is
Mumbai Suburban Railway which started operations in 1853. The
Kolkata Suburban Railway has the largest network in the entire country. The
Chennai Suburban Railway started its operations in 1931.
Suburban trains that handle commuter traffic are all
electric multiple units (EMUs). They usually have nine or 12 coaches, though can sometimes include 15 to handle rush hour traffic. One unit of an EMU train consists of one power car and two general coaches. Thus a nine coach EMU is made up of three units having one power car at each end and one at the middle. The rakes in the suburban rails run on
25 kV AC.<a href="

The suburban railways of Mumbai, Kolkata and Chennai occupy no more than 7.1% of the Indian Railways network, but account for 53.2% of all railway passengers.<a href="

rapid transit systems has led to a decline in the use of the suburban rail system.<a href="
