Are we getting suburban trains or metro? If you run suburban trains with only AC coaches, it will be a flop. What is the idea behind suburban trains? To attract common man using own two wheeler or car to train. If AC trains are run, it will not help. Each suburban train should have AC and non AC coaches.
Somehow, i feel BMTC has a role in these type of decisions. If suburban trains and metro become successful and popular, BMTC will lose revenue.
