dont know state or center who r paying for metros....but let compaire UP nd tamilnadu metro:-
1:- UP
total build - lucknow = 23 km.
kanpur = 9 km.
- 23+9 = 32 km.
under construction - agra = 30 km.
approved - meerut = 15 km.
gorakhpur = 28 km.
so total metro will be = 23+9+30+15+28
= 105 km.
we r not taking praposed metro project here.
2:- tamilnadu
total build - only in chennai
blue line = 33 km.
green line = 22 km.
- 33+22 = 55 km.
under construction -
purple line = 46 km.
orange line = 26 km.
red line = 45 km.
total = 46+26+45 = 117 km.
so total metro will be = 55+117 = 172 km.
so clearly UP is making different short metro (105 km) in different cities...meanwhile tamilnadu is making (172 km) 67 km more lengthy metro than UP in only Chennai. dont know why they r crying.
