West delhi is already well connected and all four lines are operational there in, its east delhi that needs to be better connected and has now hit this block..hopefully this will be resolved soon...
Yea, it seems there is trouble with land acquiring as in the Mukundpur-Shiv Vihar corridor . Originally the line was to start operations from the Shiv Vihar side, but now its changed plans and making operations from the Mukundpur side.
It seems that the land in the shiv vihar side ahas many trees and these needs to be cut for the metro.. but the rule says that in that case the trees needs to be planted elsewhere and this substitute land is still not identified or sanctioned.
