Hello Friends,
It was planned in the past to construct and expand the MRTS service that is offered by the Chennai from the Chennai Beach to the Velachery. The MRTS stands for Mass rapid transit system is now in the state of Dilemma whether to expand the network or to leave the project as the population of the particular segment is vast and building the network may create some problem both economically as well as physically. Do you think the Network would be build in order to enhance the transportation in the country or the state will not proceed further to build the network.
