hope it helps you
Routes and Cost Factor: Well, the routes are fixed so you have to make your way to and from the stations. But then again much the same applies to buses. If tunnelling underground is not an option, then in many cities — you cannot put a metro route on most of the older interior roads. Grading requirements also limit the places where you can take a train tracks. Even when soil supports tunnelling, Underground tunnels are extremely expensive to build, operate and maintain.
Discomfort and Unfortunate: Metros can become heavily overloaded at peak times. If the Electricity in a Metro rail goes down (even for a moment) then a lot of people will be stuck.
Electricity: The Metro network is power hungry. One network easily surpasses the power requirements of many small cities and towns (This is because the metro rail doesn’t rely on locomotive technology to create thrust but runs using electricity hungry motors)
Ticket Pricing: Depending on government attitudes -- they can be heavily subsidised and thus cheap (advantage) or (as in the UK) the government may decide to make passengers pay for the service in which case they can get expensive (passengers will tell you that's a disadvantage).
Construction Disruption: Any long-term construction project that takes more than 15 years for completion will cause significant disruption to the lives of locals during the whole course of construction. Metro Construction also affects the traffic flow badly, which makes a lot of people late for their work.
Loss of control: Before laying metro line, Citizen drivers always have control over their journeys. After metro, People will have to adjust to allowing others to control their journey. (This may not be problem for many, but is for some).
