Inter-city Rail Network in Lahore.

Today I read in the news paper that the city of Lahore is finally going to have an intercity rail network. The government was sayin that the project was going to be completed in about four years which would also consist of an underground rail somthing like a tube. But I dont think that its going to be completed that soon. Anyway lets see. Pakistan really need a good mass transit system in the big cities! Although Islamabad isnt that big as lahore and karachi but it also need an immediat form of transit system because of the large increase in its population and ever increasing traffic on the roads.
